When used judiciously — and we emphasize the word ‘judiciously,’ meaning used in conjunction with a well-planned diet and workout routine — the best non-stim fat burners can potentially help in a fat loss journey (though it’s worth noting diet and activity levels will still be the largest contributors in any weight loss plan). Whether you’re preparing for your first bodybuilding show or just focused on burning fat for your own benefit, it may be worth looking at these supplements.
Most fat burner products contain stimulants, like caffeine (although sometimes it’s yohimbine). Plenty of people are a little sensitive to these ingredients, or they want to take their pills at night time and don’t want to mess up their night of recovery and rest. We have put together a list of the best non-stim fat burners on the market to help support all of your fat-burning needs without any of the added stimulants.

(3) Each serving only costs about $0.91, which is on the lower end of the price range for non-stim fat burners.

Best Non-Stim Fat Burner for Muscle Growth
Losing muscle can be the scariest part of trying to get leaner. With Transparent Labs Fat Burner, your shreds don’t have to come at the expense of your muscle gains.
Transparent Labs Stim-Free Fat Burner
Transparent Labs has two different fat burners, one of which has stimulants. This non-stim fat burner is high in ingredients that could help with retaining hard-earned muscle mass. The first ingredient on the list for this supplement is acetyl l-carnitine, which one study found to have been significant in increasing muscle mass (4). Although this supplement is geared toward fat burning, the added 750 mg of acetyl l-carnitine gives it the benefit of potentially maintaining your muscle mass while still allowing you to pursue fat loss goals.

Best Non-Stim Fat Burner for Women
Kaged Clean Burn, although stim-free, contains a high dose of chromium, which may be helpful for overweight women, as well as specifically for women with PCOS who may experience fat gain as a side effect of the condition.
Kaged Clean Burn
Kaged Clean Burn has 134mcg of chromium, which one study suggests may be beneficial for helping young overweight women lose weight when paired with exercise. The same study suggests it may be beneficial for women who experience coronary artery disease and non-insulin-dependent diabetes and are looking to see positive improvement in weight loss. (6) This formula further includes 1,000mg of l-carnitine, 100mg of Gymnema Sylvestre extract, and 33mg of capsicum fruit, which can help with thermogenesis.
Kaged Clean Burn
This product contains 33mg of capsicum extract, which can help increase your metabolism by raising your body’s internal temperature. In addition, you'll find l-carnitine, green tea extract, and gymnema sylvestre, which can also help with fat burn and weight loss, as well as blood sugar regulation.
On top of those ingredients, you’ll find 333mg of green tea extract, and if you’re a woman suffering from the weight-gain side effects from PCOS, you may be in luck. Studies suggest that green tea may be a helpful ingredient for women who are overweight or obese from PCOS as it may potentially decrease weight, decrease fasting insulin, and decrease their levels of free testosterone. (7) It will require you to take six pills per day — two pills three times daily — so it may not be suitable for those who struggle with taking pills. This is a third-party tested fat burner and will also only cost you about $0.35 per serving.
Who Should Buy Kaged Clean Burn
Women who have PCOS and are looking for a fat burner that may support their goal to drop their BMI and lose excess body fat.
Anybody who wants a technically stim-free fat burner but does not mind the small amount of caffeine found in the green tea extract.
People who like a fat burner that is third-party tested for accuracy.
Who Shouldn’t Buy Kaged Clean Burn
People who are ultra-sensitive to caffeine. This formula contains 333mg of green tea extract.
Folks who want a fat burner that may reduce appetite and cravings should look elsewhere for a product that includes fiber.
Women who want a powder or flavored fat-burning supplement.
For women trying to lose a significant amount of weight, chromium and green tea extract may be beneficial ingredients to help you shed extra body weight. If you’re a woman with PCOS, you especially may find this combination of ingredients to be helpful in dropping the excess weight often accompanied by PCOS.
Best Non-Stim Fat Burner for Appetite Suppression
Appetite can be a huge barricade when it comes to hitting your fat loss goals. With movement and calories burned correlating to how hungry you become, it can be a difficult balance to be burning the right amount of calories for fat loss while also making sure you are satiated. Leanbean’s potential appetite suppression may be the ticket to finding the balance.
Leanbean Fat Burner
Leanbean has a dozen ingredients, but it has a strong focus on what might be the most important aspect of weight loss: your appetite. Leanbean contains 12 ingredients. A big part of the appeal is glucomannan, a thickener made from the root of the konjac plant that research suggests can suppress appetite. (8) The ingredients list also has other fat burner stalwarts like cayenne pepper and green tea extract, and black pepper extract, which a 2016 paper found may increase metabolism. (9) It’ll require you to take six pills daily, so if that sounds daunting, you may want to opt for a fat burner with fewer pills per serving.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Leanbean fat burner seems a little low in green coffee extract and raspberry ketones, but we were pretty impressed. It contains a small amount of natural caffeine — 50 milligrams — which is less than a cup of coffee.
Who Should Buy Leanbean
People who have trouble with their appetite during weight loss, LeanBean has a strong emphasis on this aspect.
Anybody who likes cayenne, garcinia Cambogia, turmeric, or green tea extract — these popular fat burner ingredients are well dosed in LeanBean.
Those looking to suppress appetite as their main way of losing weight and burning fat.
Who Shouldn’t Buy Leanbean
People with a sensitivity to caffeine. The amount found in LeanBean is less than 10 percent of a small cup of coffee, but it’s worth mentioning.
Folks who like green coffee and raspberry ketones, it’s a little low on these ingredients.
Those who don’t want to take six pills each day.
LeanBean’s tiny amount of caffeine may disqualify it for some consumers, but for the average person, it’ll be barely noticeable, and it’s otherwise a terrific product.

Best Non-Stim Fat Burner for Sleep
Legion Phoenix Stimulant-Free Fat Burner has a strong ingredient list to potentially help you burn fat, and curb appetite and cravings — but it also includes ingredients that may aid in your sleep and impact your memory of your dreams.
Legion Phoenix Stimulant-Free Fat Burner
Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may aid you in your weight-loss journey. Among the list of ingredients is Caralluma Fimbriata extract (CFE) which has been shown to reduce stress and anxiety in adults (10). When our stress and anxiety are lowered, the outcome may lead to better sleep. Another study found that there is a statistically significant relationship between high stress and poor sleep, meaning it can be extremely helpful to lower stress levels to improve sleep quality (11).
Legion Phoenix
Legion's Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.
CFE comes in at 1,000 mg per serving in the Phoenix blend, making it a helpful ingredient in this toolbox to potentially lower stress and cortisol levels, and lead to better sleep, and in turn, better fat-loss capabilities. This ingredient list also contains 5-HTP, a natural serotonin booster, which can potentially improve mood, lessen anxiety, and give you a better night’s sleep, especially if you suffer from insomnia (12). You’ll have to take three vegetarian capsules for a single serving of this fat burner and it will cost you$1.66 per serving.
Who Should Buy Legion Phoenix Stimulant-Free Fat Burner
Those who are looking to possibly lower their stress and cortisol levels, and in turn, may end up with a better night’s sleep will appreciate the addition of CFE and 5-HTP in this formula.
Athletes who want a fat burner with the addition of ingredients such as l-dopa to potentially curb cravings and appetite.
Anyone who wants ingredients that may help resolve insomnia and boost your mood will like the ingredients list on this product — especially 5-HTP.
Who Shouldn’t Buy Legion Phoenix Stimulant-Free Fat Burner
Folks who are looking for a basic formula may want to look elsewhere for a smaller ingredient list.
Someone looking for a supplement fully geared towards sleep may want to look for a fat burner or another supplement that has sleep at the forefront— this supplement has the added benefit of ingredients that may lead to better sleep, but the focus is generally on fat burning.
Those who are on a budget can find a less expensive option on this list.
Legion’s Phoenix Stimulant-Free Fat Burner is ideal for those who want their fat burner to possibly aid as a sleeping agent, as well. This formula contains 5-HTP, as well as CFE, which may lead to lowered stress levels and potentially improved sleep.

Best Non-Stim Fat Burner To Reduce Cravings
Cravings are one of the forefront issues when it comes to fat loss. This formula contains natural appetite suppressants, which can lead to a decrease in cravings, as well.
Leanbean Fat Burner
The best fat burners, in our opinion, impact fat loss in multiple ways: boosting metabolism, appetite suppression, and increasing energy and focus. Leanbean came out on top because of its potent dosage and research-backed ingredients. This fat burner contains glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Plus, you’ll find vitamins B6 and B12, which can help with your energy throughout the day. This product is marketed to women, but it’s a solid non-stim fat burner across the board — one of the only downsides is that you do have to take six capsules a day for a full dose. It’s also worth noting that this product does contain 50mg of caffeine, which is much less than a single cup of coffee, but not inconsequential.
Who Should Buy Leanbean
Anyone who wants a variety of ingredients working in concert to increase fat loss and energy expenditure.
People interested in energy boosters: Vitamins B6 and B12 are key for maintaining normal energy levels.
Those who find a fat-burner with appetite-suppressing ingredients to be appealing will enjoy this ingredient list.
Who Shouldn’t Buy Leanbean
Those who don’t want to have to take a lot of pills. Leanbean requires six daily.
Anecdotally, it might not be ideal for people with very sensitive stomachs as glucomannan can be harsh on some.
If you want a product free of caffeine entirely, you can find other options on this list that will work for you — this supp contains 50mg of caffeine.
We like Leanbean for its wide variety of fat burning and appetite-suppressing ingredients. If you’re okay with taking a decent number of pills, this supplement is the way to go to potentially help suppress your appetite or reduce cravings overall.

The Benefits of Non-Stim Fat Burner
While there are many potential benefits to supplementing with a fat burner, non-stim fat burners offer their own unique benefits. Whether you’re looking to increase thermogenesis, boost fat oxidation, achieve a higher metabolic rate, decrease appetite, or just avoid the poor sleep that may occur when you take stimulants, we detail each potential benefit below.
Non-Stim Benefits
When you opt for a stim-free fat burner, you choose to forego the caffeine or stimulants that are often utilized as fat-burning ingredients. There are many potential benefits to choosing the non-stim route, and it may be the best choice for you if you enjoy getting your stimulants from a caffeine source like coffee, or if you’re on medications that are already loaded with stimulants. It’s also a great choice for those who are easily affected by stimulants but still want a fat-burning supplement to assist them in their fat-burning quest.
Increased Thermogenesis
Thermogenesis is the process of heat generation in the body, which may help burn more calories through increased heat. A thermogenic aid may increase thermogenesis, and therefore, potentially increase calories burned. This includes energy expenditure from ingesting, digesting, and processing the food we eat. (13)

Not all fat burners are created with thermogenesis in mind, but if you’re interested in the potential benefits of thermogenesis, make sure you pick a supplement that states it is a thermogenic aid. It is worth noting you probably won’t burn a ton of extra calories, but if your end goal is fat loss and your diet, cardio, and resistance training set you up for success, this can be a potentially helpful tool for that extra push.
Increased Fat Oxidation
Fat oxidation is the process that breaks down fat stores in the body (triglycerides) that we accumulate from taking in excess fat that we do not burn throughout the day in our daily activities. In order for the body to target fat oxidation over other types of energy releases, you may have to work out at higher intensities — specifically, endurance training that lasts less than two hours can help facilitate fat oxidation. (14) Fat oxidation may also be a byproduct of some fat burning supplements.
Increased Metabolic Rate
The metabolic rate — also known as the basal metabolic rate — is the number of calories that are necessary for the body to perform its various functions while it’s at rest. Some fat burners have the potential to increase metabolic processes and in their wake, help you burn more calories.
Decreased Appetite
The science-backed way to lose weight is by burning more calories than you are taking in. Many know this as CICO, or calories in versus calories out. By supplementing with a fat burner that aims to decrease your appetite, you may have fewer cravings, food binges, or desires to consume an excessive number of calories.

Although sticking to a diet plan, macro breakdown, or good program will be your best friend here, a supplement that may help decrease your appetite can be a helpful tool, as well.
How We Chose The Best Non-Stim Fat Burners
When assessing the usefulness of a fat burner supplement, we looked at several factors. Sure, it has green tea extract, but is that enough? Here’s what you should think about.
Fat Oxidation
Perhaps the most popular ingredient in “fat burners” means it helps to burn fat, or more specifically, it helps to increase the amount of energy you burn from stored fat compared to stored carbs. Popular examples include green tea extract and l-carnitine.
Increasing Metabolic Rate
Increasing metabolic rate can be described as whether or not a product burns more calories. A popular example is cayenne peppers, which some research has found to burn an extra 50 or so calories, depending on the dosage. Other examples include hordenine and synephrine.
Appetite Suppression
There are a few ways appetite suppression works. A popular one is with ingredients that expand in the stomach, like glucomannan (found in LeanBean) and psyllium husk. A more popular method is 5-HTP, which may help with serotonin production, which appears to help with satiety and cravings.
Transparency
Scores of fat burners hide their ingredients behind proprietary blends so that the customer doesn’t know the exact amount of each. It helps them to keep their formula from being stolen by competitors, sure, but it also means that you don’t know how effective the product is.
How Much Do Non-Stim Fat Burners Cost?
Non-stim fat burners vary in their design, purpose, and ingredient list, which will affect the price point of each product. This list ranges in price from around $0.33 to $2.00 per serving, with many of the higher priced products offering a more robust ingredients list.

What To Consider Before Buying Non-Stim Fat Burners
These products are prone to exaggeration on the part of the manufacturers and wishful thinking by consumers. Make sure you’re mindful of these points.
Know Your Calories
Way too many people think adding a fat burner, with no other changes to their diet, will produce a six-pack. Fat burners might help burn some extra calories, but if you don’t know how many calories you’re burning, it’s a moot point.
Jacob Lund/Shutterstock
Find out your ideal calories with a macro calculator — then adding a fat burner might give you some support.
Manage Your Expectations
It’s generally understood that a pound of fat loss per week is very fast, and you can maybe get to two pounds if you’re quite overweight or obese. Anyone who says they lost 20 pounds in a month is exaggerating — you need to be patient.
Exercise Regularly
Many of the ingredients linked to fat oxidation produce their best results with a solid exercise routine: They’re meant to increase the amount of fat burned during exercise.
Credit: Da Antipina / Shutterstock
In addition, exercise helps to burn more calories and improve body composition. Taking a fat burner without a workout routine may produce suboptimal results.
Speak to a Physician
This is absolutely key. It would be best if you never made any changes to your diet or exercise regimen without first speaking to a doctor. This is especially the case with easily misunderstood supplements like fat burners.
Final Word
Fat burners are meant to act as an aid for fat burning goals in conjunction with a solid diet or meal plan, resistance training, and a cardio routine. Fat burners are not magic pills that will land you a top spot on the before and after picture list, but they can be a helpful tool to get you closer to your goals. If you’re sensitive to caffeine or just prefer to get your caffeine from a source outside of your fat burner, this list is chock full of excellent fat burning supplements sans the stimulants.
As you can see, there are many things to keep in mind when choosing the best non-stim fat burner, even when you’re trying to uncomplicate the ingredients list by removing caffeine. The right product totally depends on your own preferences, but we’ve found many non-stim products that operate on multiple fronts: potential appetite suppression, fat oxidation, and increased thermogenesis. Whatever your preference, there’s likely an option for you on this list.
FAQs
Are non-stim fat burners still effective?Yes; although caffeine may be a helpful fat burning ingredient, there are many non-stimulant fat burning ingredients available that also have the potential to help you reduce body fat. Some of the ingredients you’ll find in these non-stim fat burners are chromium, cayenne pepper which is also called capsicum, carnitine, and choline.
Why would I choose a non-stim fat burner over one with stimulants?There are several reasons someone may opt for a stim-free fat burner. Some people may be sensitive to stimulants and choose not to include them in their diet. Some may prefer to get their caffeine intake from coffee or a caffeinated tea. Others may not like how stimulants make them feel later in the day. There is no right or wrong answer; it just boils down to what makes the most sense for your lifestyle choices.
What are the downsides of a stim-free fat burner?Although there are no technical “downsides” as non-stim fat burners can be just as effective as fat-burners with stimulants, the only thing you’d be missing out on is another potential avenue for fat burning, as well as the heightened sense of alertness or focus some people receive from caffeine.
How much do stim-free fat burners cost?Stim-free fat burners can range in price, and on this list alone, you’ll find a range between around $0.33 and $2.00 per serving. The average price we found was about $1.12 per serving.
What is the best non-stim fat burner?With plenty of non-stim fat burners to choose from, we think Transparent Labs Stim Free Fat Burner is the best on the market.

When used judiciously — and we emphasize the word ‘judiciously,’ meaning used in conjunction with a well-planned diet and workout routine — the best non-stim fat burners can potentially help in a fat loss journey (though it’s worth noting diet and activity levels will still be the largest contributors in any weight loss plan). Whether you’re preparing for your first bodybuilding show or just focused on burning fat for your own benefit, it may be worth looking at these supplements.
Most fat burner products contain stimulants, like caffeine (although sometimes it’s yohimbine). Plenty of people are a little sensitive to these ingredients, or they want to take their pills at night time and don’t want to mess up their night of recovery and rest. We have put together a list of the best non-stim fat burners on the market to help support all of your fat-burning needs without any of the added stimulants.

Best Non-Stim Fat Burner
There can be a lot to think about when going into a fat-burning phase and picking the right supplement for your goals. This pick hits many of the essentials we like to see in a non-stim fat burner. It has a nice variety of ingredients, is third-party tested, and contains the amino acid carnitine, which may help you pack on muscle mass while also burning fat.

Best Non-Stim Fat Burner for Muscle Growth
Losing muscle can be the scariest part of trying to get leaner. With Transparent Labs Fat Burner, your shreds don’t have to come at the expense of your muscle gains.
Transparent Labs Stim-Free Fat Burner
Transparent Labs has two different fat burners, one of which has stimulants. This non-stim fat burner is high in ingredients that could help with retaining hard-earned muscle mass. The first ingredient on the list for this supplement is acetyl l-carnitine, which one study found to have been significant in increasing muscle mass (4). Although this supplement is geared toward fat burning, the added 750 mg of acetyl l-carnitine gives it the benefit of potentially maintaining your muscle mass while still allowing you to pursue fat loss goals.

Best Non-Stim Fat Burner for the Money
Reaching your fitness goals can get pricey regardless of what your desired outcome is. This can include gym memberships, food, and of course — supplements. This fat burner may be the key to helping you unlock your fat-burning potential without breaking the bank.
Kaged Clean Burn
Just because you’re on a budget doesn’t mean you can’t find a solid stim-free fat burner. This option may only contain six ingredients, but in the right combination, numbers don’t matter. You’ll find 400 mcg of chromium, 100mg of Capsimax, 1000 mg of green tea extract, and a serious helping of 3,000mg l-carnitine to name a few.

The first three may lead to better fat burning, while the l-carnitine may also benefit muscle maintenance. Plus, at a serving size of two capsules, you get 90 servings per container, putting this product at a low cost of about $0.35 per serving.

Best Non-Stim Fat Burner Pre-Workout
For those who prefer to take their fat burner as a pre-workout in hopes of boosting your intra-workout fat burn, this may be the product for you.
Transparent Labs Stim-Free Pre-Workout

Best Non-Stim Fat Burner for Women
Kaged Clean Burn, although stim-free, contains a high dose of chromium, which may be helpful for overweight women, as well as specifically for women with PCOS who may experience fat gain as a side effect of the condition.
Kaged Clean Burn
Kaged Clean Burn has 134mcg of chromium, which one study suggests may be beneficial for helping young overweight women lose weight when paired with exercise. The same study suggests it may be beneficial for women who experience coronary artery disease and non-insulin-dependent diabetes and are looking to see positive improvement in weight loss. (6) This formula further includes 1,000mg of l-carnitine, 100mg of Gymnema Sylvestre extract, and 33mg of capsicum fruit, which can help with thermogenesis.
Kaged Clean Burn
This product contains 33mg of capsicum extract, which can help increase your metabolism by raising your body’s internal temperature. In addition, you'll find l-carnitine, green tea extract, and gymnema sylvestre, which can also help with fat burn and weight loss, as well as blood sugar regulation.
On top of those ingredients, you’ll find 333mg of green tea extract, and if you’re a woman suffering from the weight-gain side effects from PCOS, you may be in luck. Studies suggest that green tea may be a helpful ingredient for women who are overweight or obese from PCOS as it may potentially decrease weight, decrease fasting insulin, and decrease their levels of free testosterone. (7) It will require you to take six pills per day — two pills three times daily — so it may not be suitable for those who struggle with taking pills. This is a third-party tested fat burner and will also only cost you about $0.35 per serving.

Best Non-Stim Fat Burner for Appetite Suppression
Appetite can be a huge barricade when it comes to hitting your fat loss goals. With movement and calories burned correlating to how hungry you become, it can be a difficult balance to be burning the right amount of calories for fat loss while also making sure you are satiated. Leanbean’s potential appetite suppression may be the ticket to finding the balance.
Leanbean Fat Burner
Leanbean has a dozen ingredients, but it has a strong focus on what might be the most important aspect of weight loss: your appetite. Leanbean contains 12 ingredients. A big part of the appeal is glucomannan, a thickener made from the root of the konjac plant that research suggests can suppress appetite. (8) The ingredients list also has other fat burner stalwarts like cayenne pepper and green tea extract, and black pepper extract, which a 2016 paper found may increase metabolism. (9) It’ll require you to take six pills daily, so if that sounds daunting, you may want to opt for a fat burner with fewer pills per serving.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Leanbean fat burner seems a little low in green coffee extract and raspberry ketones, but we were pretty impressed. It contains a small amount of natural caffeine — 50 milligrams — which is less than a cup of coffee.

Best Non-Stim Fat Burner for Sleep
Legion Phoenix Stimulant-Free Fat Burner has a strong ingredient list to potentially help you burn fat, and curb appetite and cravings — but it also includes ingredients that may aid in your sleep and impact your memory of your dreams.
Legion Phoenix Stimulant-Free Fat Burner
Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may aid you in your weight-loss journey. Among the list of ingredients is Caralluma Fimbriata extract (CFE) which has been shown to reduce stress and anxiety in adults (10). When our stress and anxiety are lowered, the outcome may lead to better sleep. Another study found that there is a statistically significant relationship between high stress and poor sleep, meaning it can be extremely helpful to lower stress levels to improve sleep quality (11).
Legion Phoenix
Legion's Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.
CFE comes in at 1,000 mg per serving in the Phoenix blend, making it a helpful ingredient in this toolbox to potentially lower stress and cortisol levels, and lead to better sleep, and in turn, better fat-loss capabilities. This ingredient list also contains 5-HTP, a natural serotonin booster, which can potentially improve mood, lessen anxiety, and give you a better night’s sleep, especially if you suffer from insomnia (12). You’ll have to take three vegetarian capsules for a single serving of this fat burner and it will cost you$1.66 per serving.

Best Non-Stim Fat Burner To Reduce Cravings
Cravings are one of the forefront issues when it comes to fat loss. This formula contains natural appetite suppressants, which can lead to a decrease in cravings, as well.
Leanbean Fat Burner
The best fat burners, in our opinion, impact fat loss in multiple ways: boosting metabolism, appetite suppression, and increasing energy and focus. Leanbean came out on top because of its potent dosage and research-backed ingredients. This fat burner contains glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Plus, you’ll find vitamins B6 and B12, which can help with your energy throughout the day. This product is marketed to women, but it’s a solid non-stim fat burner across the board — one of the only downsides is that you do have to take six capsules a day for a full dose. It’s also worth noting that this product does contain 50mg of caffeine, which is much less than a single cup of coffee, but not inconsequential.

The Benefits of Non-Stim Fat Burner
While there are many potential benefits to supplementing with a fat burner, non-stim fat burners offer their own unique benefits. Whether you’re looking to increase thermogenesis, boost fat oxidation, achieve a higher metabolic rate, decrease appetite, or just avoid the poor sleep that may occur when you take stimulants, we detail each potential benefit below.
Non-Stim Benefits
When you opt for a stim-free fat burner, you choose to forego the caffeine or stimulants that are often utilized as fat-burning ingredients. There are many potential benefits to choosing the non-stim route, and it may be the best choice for you if you enjoy getting your stimulants from a caffeine source like coffee, or if you’re on medications that are already loaded with stimulants. It’s also a great choice for those who are easily affected by stimulants but still want a fat-burning supplement to assist them in their fat-burning quest.

Best Non-Stim Fat Burner for Women
Kaged Clean Burn, although stim-free, contains a high dose of chromium, which may be helpful for overweight women, as well as specifically for women with PCOS who may experience fat gain as a side effect of the condition.
Kaged Clean Burn
Kaged Clean Burn has 134mcg of chromium, which one study suggests may be beneficial for helping young overweight women lose weight when paired with exercise. The same study suggests it may be beneficial for women who experience coronary artery disease and non-insulin-dependent diabetes and are looking to see positive improvement in weight loss. (6) This formula further includes 1,000mg of l-carnitine, 100mg of Gymnema Sylvestre extract, and 33mg of capsicum fruit, which can help with thermogenesis.
Kaged Clean Burn
This product contains 33mg of capsicum extract, which can help increase your metabolism by raising your body’s internal temperature. In addition, you'll find l-carnitine, green tea extract, and gymnema sylvestre, which can also help with fat burn and weight loss, as well as blood sugar regulation.
On top of those ingredients, you’ll find 333mg of green tea extract, and if you’re a woman suffering from the weight-gain side effects from PCOS, you may be in luck. Studies suggest that green tea may be a helpful ingredient for women who are overweight or obese from PCOS as it may potentially decrease weight, decrease fasting insulin, and decrease their levels of free testosterone. (7) It will require you to take six pills per day — two pills three times daily — so it may not be suitable for those who struggle with taking pills. This is a third-party tested fat burner and will also only cost you about $0.35 per serving.
Who Should Buy Kaged Clean Burn
Women who have PCOS and are looking for a fat burner that may support their goal to drop their BMI and lose excess body fat.
Anybody who wants a technically stim-free fat burner but does not mind the small amount of caffeine found in the green tea extract.
People who like a fat burner that is third-party tested for accuracy.
Who Shouldn’t Buy Kaged Clean Burn
People who are ultra-sensitive to caffeine. This formula contains 333mg of green tea extract.
Folks who want a fat burner that may reduce appetite and cravings should look elsewhere for a product that includes fiber.
Women who want a powder or flavored fat-burning supplement.
For women trying to lose a significant amount of weight, chromium and green tea extract may be beneficial ingredients to help you shed extra body weight. If you’re a woman with PCOS, you especially may find this combination of ingredients to be helpful in dropping the excess weight often accompanied by PCOS.
Best Non-Stim Fat Burner for Appetite Suppression
Appetite can be a huge barricade when it comes to hitting your fat loss goals. With movement and calories burned correlating to how hungry you become, it can be a difficult balance to be burning the right amount of calories for fat loss while also making sure you are satiated. Leanbean’s potential appetite suppression may be the ticket to finding the balance.
Leanbean Fat Burner
Leanbean has a dozen ingredients, but it has a strong focus on what might be the most important aspect of weight loss: your appetite. Leanbean contains 12 ingredients. A big part of the appeal is glucomannan, a thickener made from the root of the konjac plant that research suggests can suppress appetite. (8) The ingredients list also has other fat burner stalwarts like cayenne pepper and green tea extract, and black pepper extract, which a 2016 paper found may increase metabolism. (9) It’ll require you to take six pills daily, so if that sounds daunting, you may want to opt for a fat burner with fewer pills per serving.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Leanbean fat burner seems a little low in green coffee extract and raspberry ketones, but we were pretty impressed. It contains a small amount of natural caffeine — 50 milligrams — which is less than a cup of coffee.
Who Should Buy Leanbean
People who have trouble with their appetite during weight loss, LeanBean has a strong emphasis on this aspect.
Anybody who likes cayenne, garcinia Cambogia, turmeric, or green tea extract — these popular fat burner ingredients are well dosed in LeanBean.
Those looking to suppress appetite as their main way of losing weight and burning fat.
Who Shouldn’t Buy Leanbean
People with a sensitivity to caffeine. The amount found in LeanBean is less than 10 percent of a small cup of coffee, but it’s worth mentioning.
Folks who like green coffee and raspberry ketones, it’s a little low on these ingredients.
Those who don’t want to take six pills each day.
LeanBean’s tiny amount of caffeine may disqualify it for some consumers, but for the average person, it’ll be barely noticeable, and it’s otherwise a terrific product.

Best Non-Stim Fat Burner for Sleep
Legion Phoenix Stimulant-Free Fat Burner has a strong ingredient list to potentially help you burn fat, and curb appetite and cravings — but it also includes ingredients that may aid in your sleep and impact your memory of your dreams.
Legion Phoenix Stimulant-Free Fat Burner
Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may aid you in your weight-loss journey. Among the list of ingredients is Caralluma Fimbriata extract (CFE) which has been shown to reduce stress and anxiety in adults (10). When our stress and anxiety are lowered, the outcome may lead to better sleep. Another study found that there is a statistically significant relationship between high stress and poor sleep, meaning it can be extremely helpful to lower stress levels to improve sleep quality (11).
Legion Phoenix
Legion's Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.
CFE comes in at 1,000 mg per serving in the Phoenix blend, making it a helpful ingredient in this toolbox to potentially lower stress and cortisol levels, and lead to better sleep, and in turn, better fat-loss capabilities. This ingredient list also contains 5-HTP, a natural serotonin booster, which can potentially improve mood, lessen anxiety, and give you a better night’s sleep, especially if you suffer from insomnia (12). You’ll have to take three vegetarian capsules for a single serving of this fat burner and it will cost you$1.66 per serving.
Who Should Buy Legion Phoenix Stimulant-Free Fat Burner
Those who are looking to possibly lower their stress and cortisol levels, and in turn, may end up with a better night’s sleep will appreciate the addition of CFE and 5-HTP in this formula.
Athletes who want a fat burner with the addition of ingredients such as l-dopa to potentially curb cravings and appetite.
Anyone who wants ingredients that may help resolve insomnia and boost your mood will like the ingredients list on this product — especially 5-HTP.
Who Shouldn’t Buy Legion Phoenix Stimulant-Free Fat Burner
Folks who are looking for a basic formula may want to look elsewhere for a smaller ingredient list.
Someone looking for a supplement fully geared towards sleep may want to look for a fat burner or another supplement that has sleep at the forefront— this supplement has the added benefit of ingredients that may lead to better sleep, but the focus is generally on fat burning.
Those who are on a budget can find a less expensive option on this list.
Legion’s Phoenix Stimulant-Free Fat Burner is ideal for those who want their fat burner to possibly aid as a sleeping agent, as well. This formula contains 5-HTP, as well as CFE, which may lead to lowered stress levels and potentially improved sleep.

Best Non-Stim Fat Burner To Reduce Cravings
Cravings are one of the forefront issues when it comes to fat loss. This formula contains natural appetite suppressants, which can lead to a decrease in cravings, as well.
Leanbean Fat Burner
The best fat burners, in our opinion, impact fat loss in multiple ways: boosting metabolism, appetite suppression, and increasing energy and focus. Leanbean came out on top because of its potent dosage and research-backed ingredients. This fat burner contains glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Plus, you’ll find vitamins B6 and B12, which can help with your energy throughout the day. This product is marketed to women, but it’s a solid non-stim fat burner across the board — one of the only downsides is that you do have to take six capsules a day for a full dose. It’s also worth noting that this product does contain 50mg of caffeine, which is much less than a single cup of coffee, but not inconsequential.
Who Should Buy Leanbean
Anyone who wants a variety of ingredients working in concert to increase fat loss and energy expenditure.
People interested in energy boosters: Vitamins B6 and B12 are key for maintaining normal energy levels.
Those who find a fat-burner with appetite-suppressing ingredients to be appealing will enjoy this ingredient list.
Who Shouldn’t Buy Leanbean
Those who don’t want to have to take a lot of pills. Leanbean requires six daily.
Anecdotally, it might not be ideal for people with very sensitive stomachs as glucomannan can be harsh on some.
If you want a product free of caffeine entirely, you can find other options on this list that will work for you — this supp contains 50mg of caffeine.
We like Leanbean for its wide variety of fat burning and appetite-suppressing ingredients. If you’re okay with taking a decent number of pills, this supplement is the way to go to potentially help suppress your appetite or reduce cravings overall.

The Benefits of Non-Stim Fat Burner
While there are many potential benefits to supplementing with a fat burner, non-stim fat burners offer their own unique benefits. Whether you’re looking to increase thermogenesis, boost fat oxidation, achieve a higher metabolic rate, decrease appetite, or just avoid the poor sleep that may occur when you take stimulants, we detail each potential benefit below.
Non-Stim Benefits
When you opt for a stim-free fat burner, you choose to forego the caffeine or stimulants that are often utilized as fat-burning ingredients. There are many potential benefits to choosing the non-stim route, and it may be the best choice for you if you enjoy getting your stimulants from a caffeine source like coffee, or if you’re on medications that are already loaded with stimulants. It’s also a great choice for those who are easily affected by stimulants but still want a fat-burning supplement to assist them in their fat-burning quest.
Increased Thermogenesis
Thermogenesis is the process of heat generation in the body, which may help burn more calories through increased heat. A thermogenic aid may increase thermogenesis, and therefore, potentially increase calories burned. This includes energy expenditure from ingesting, digesting, and processing the food we eat. (13)

Not all fat burners are created with thermogenesis in mind, but if you’re interested in the potential benefits of thermogenesis, make sure you pick a supplement that states it is a thermogenic aid. It is worth noting you probably won’t burn a ton of extra calories, but if your end goal is fat loss and your diet, cardio, and resistance training set you up for success, this can be a potentially helpful tool for that extra push.
Increased Fat Oxidation
Fat oxidation is the process that breaks down fat stores in the body (triglycerides) that we accumulate from taking in excess fat that we do not burn throughout the day in our daily activities. In order for the body to target fat oxidation over other types of energy releases, you may have to work out at higher intensities — specifically, endurance training that lasts less than two hours can help facilitate fat oxidation. (14) Fat oxidation may also be a byproduct of some fat burning supplements.
Increased Metabolic Rate
The metabolic rate — also known as the basal metabolic rate — is the number of calories that are necessary for the body to perform its various functions while it’s at rest. Some fat burners have the potential to increase metabolic processes and in their wake, help you burn more calories.
Decreased Appetite
The science-backed way to lose weight is by burning more calories than you are taking in. Many know this as CICO, or calories in versus calories out. By supplementing with a fat burner that aims to decrease your appetite, you may have fewer cravings, food binges, or desires to consume an excessive number of calories.

Although sticking to a diet plan, macro breakdown, or good program will be your best friend here, a supplement that may help decrease your appetite can be a helpful tool, as well.
How We Chose The Best Non-Stim Fat Burners
When assessing the usefulness of a fat burner supplement, we looked at several factors. Sure, it has green tea extract, but is that enough? Here’s what you should think about.
Fat Oxidation
Perhaps the most popular ingredient in “fat burners” means it helps to burn fat, or more specifically, it helps to increase the amount of energy you burn from stored fat compared to stored carbs. Popular examples include green tea extract and l-carnitine.
Increasing Metabolic Rate
Increasing metabolic rate can be described as whether or not a product burns more calories. A popular example is cayenne peppers, which some research has found to burn an extra 50 or so calories, depending on the dosage. Other examples include hordenine and synephrine.
Appetite Suppression
There are a few ways appetite suppression works. A popular one is with ingredients that expand in the stomach, like glucomannan (found in LeanBean) and psyllium husk. A more popular method is 5-HTP, which may help with serotonin production, which appears to help with satiety and cravings.
Transparency
Scores of fat burners hide their ingredients behind proprietary blends so that the customer doesn’t know the exact amount of each. It helps them to keep their formula from being stolen by competitors, sure, but it also means that you don’t know how effective the product is.
How Much Do Non-Stim Fat Burners Cost?
Non-stim fat burners vary in their design, purpose, and ingredient list, which will affect the price point of each product. This list ranges in price from around $0.33 to $2.00 per serving, with many of the higher priced products offering a more robust ingredients list.

You can assess your needs and desires in a non-stim fat burner, and it’s likely you’ll be able to find a non-stim fat burner that’s within your budget to match.
What To Consider Before Buying Non-Stim Fat Burners
These products are prone to exaggeration on the part of the manufacturers and wishful thinking by consumers. Make sure you’re mindful of these points.
Know Your Calories
Way too many people think adding a fat burner, with no other changes to their diet, will produce a six-pack. Fat burners might help burn some extra calories, but if you don’t know how many calories you’re burning, it’s a moot point.
Jacob Lund/Shutterstock
Find out your ideal calories with a macro calculator — then adding a fat burner might give you some support.
Manage Your Expectations
It’s generally understood that a pound of fat loss per week is very fast, and you can maybe get to two pounds if you’re quite overweight or obese. Anyone who says they lost 20 pounds in a month is exaggerating — you need to be patient.
Exercise Regularly
Many of the ingredients linked to fat oxidation produce their best results with a solid exercise routine: They’re meant to increase the amount of fat burned during exercise.
Credit: Da Antipina / Shutterstock
In addition, exercise helps to burn more calories and improve body composition. Taking a fat burner without a workout routine may produce suboptimal results.
Speak to a Physician
This is absolutely key. It would be best if you never made any changes to your diet or exercise regimen without first speaking to a doctor. This is especially the case with easily misunderstood supplements like fat burners.
Final Word
Fat burners are meant to act as an aid for fat burning goals in conjunction with a solid diet or meal plan, resistance training, and a cardio routine. Fat burners are not magic pills that will land you a top spot on the before and after picture list, but they can be a helpful tool to get you closer to your goals. If you’re sensitive to caffeine or just prefer to get your caffeine from a source outside of your fat burner, this list is chock full of excellent fat burning supplements sans the stimulants.
As you can see, there are many things to keep in mind when choosing the best non-stim fat burner, even when you’re trying to uncomplicate the ingredients list by removing caffeine. The right product totally depends on your own preferences, but we’ve found many non-stim products that operate on multiple fronts: potential appetite suppression, fat oxidation, and increased thermogenesis. Whatever your preference, there’s likely an option for you on this list.
FAQs
Are non-stim fat burners still effective?Yes; although caffeine may be a helpful fat burning ingredient, there are many non-stimulant fat burning ingredients available that also have the potential to help you reduce body fat. Some of the ingredients you’ll find in these non-stim fat burners are chromium, cayenne pepper which is also called capsicum, carnitine, and choline.
Why would I choose a non-stim fat burner over one with stimulants?There are several reasons someone may opt for a stim-free fat burner. Some people may be sensitive to stimulants and choose not to include them in their diet. Some may prefer to get their caffeine intake from coffee or a caffeinated tea. Others may not like how stimulants make them feel later in the day. There is no right or wrong answer; it just boils down to what makes the most sense for your lifestyle choices.
What are the downsides of a stim-free fat burner?Although there are no technical “downsides” as non-stim fat burners can be just as effective as fat-burners with stimulants, the only thing you’d be missing out on is another potential avenue for fat burning, as well as the heightened sense of alertness or focus some people receive from caffeine.
How much do stim-free fat burners cost?Stim-free fat burners can range in price, and on this list alone, you’ll find a range between around $0.33 and $2.00 per serving. The average price we found was about $1.12 per serving.
What is the best non-stim fat burner?With plenty of non-stim fat burners to choose from, we think Transparent Labs Stim Free Fat Burner is the best on the market. We love its ingredient list, which includes vitamin B12, carnitine, and forskolin, and we appreciate that it is totally free of any stimulants, including caffeine. Plus, at $0.91 per serving, it’s hard to beat the high quality for the price.

When used judiciously — and we emphasize the word ‘judiciously,’ meaning used in conjunction with a well-planned diet and workout routine — the best non-stim fat burners can potentially help in a fat loss journey (though it’s worth noting diet and activity levels will still be the largest contributors in any weight loss plan). Whether you’re preparing for your first bodybuilding show or just focused on burning fat for your own benefit, it may be worth looking at these supplements.
Most fat burner products contain stimulants, like caffeine (although sometimes it’s yohimbine). Plenty of people are a little sensitive to these ingredients, or they want to take their pills at night time and don’t want to mess up their night of recovery and rest. We have put together a list of the best non-stim fat burners on the market to help support all of your fat-burning needs without any of the added stimulants.

Best Non-Stim Fat Burner for Women
Kaged Clean Burn, although stim-free, contains a high dose of chromium, which may be helpful for overweight women, as well as specifically for women with PCOS who may experience fat gain as a side effect of the condition.
Kaged Clean Burn
Kaged Clean Burn has 134mcg of chromium, which one study suggests may be beneficial for helping young overweight women lose weight when paired with exercise. The same study suggests it may be beneficial for women who experience coronary artery disease and non-insulin-dependent diabetes and are looking to see positive improvement in weight loss. (6) This formula further includes 1,000mg of l-carnitine, 100mg of Gymnema Sylvestre extract, and 33mg of capsicum fruit, which can help with thermogenesis.
Kaged Clean Burn
This product contains 33mg of capsicum extract, which can help increase your metabolism by raising your body’s internal temperature. In addition, you'll find l-carnitine, green tea extract, and gymnema sylvestre, which can also help with fat burn and weight loss, as well as blood sugar regulation.
On top of those ingredients, you’ll find 333mg of green tea extract, and if you’re a woman suffering from the weight-gain side effects from PCOS, you may be in luck. Studies suggest that green tea may be a helpful ingredient for women who are overweight or obese from PCOS as it may potentially decrease weight, decrease fasting insulin, and decrease their levels of free testosterone. (7) It will require you to take six pills per day — two pills three times daily — so it may not be suitable for those who struggle with taking pills. This is a third-party tested fat burner and will also only cost you about $0.35 per serving.
Who Should Buy Kaged Clean Burn
- Women who have PCOS and are looking for a fat burner that may support their goal to drop their BMI and lose excess body fat.
- Anybody who wants a technically stim-free fat burner but does not mind the small amount of caffeine found in the green tea extract.
- People who like a fat burner that is third-party tested for accuracy.
- People who are ultra-sensitive to caffeine. This formula contains 333mg of green tea extract.
- Folks who want a fat burner that may reduce appetite and cravings should look elsewhere for a product that includes fiber.
- Women who want a powder or flavored fat-burning supplement.
Best Non-Stim Fat Burner for Appetite Suppression
Appetite can be a huge barricade when it comes to hitting your fat loss goals. With movement and calories burned correlating to how hungry you become, it can be a difficult balance to be burning the right amount of calories for fat loss while also making sure you are satiated. Leanbean’s potential appetite suppression may be the ticket to finding the balance.
Leanbean Fat Burner
Leanbean has a dozen ingredients, but it has a strong focus on what might be the most important aspect of weight loss: your appetite. Leanbean contains 12 ingredients. A big part of the appeal is glucomannan, a thickener made from the root of the konjac plant that research suggests can suppress appetite. (8) The ingredients list also has other fat burner stalwarts like cayenne pepper and green tea extract, and black pepper extract, which a 2016 paper found may increase metabolism. (9) It’ll require you to take six pills daily, so if that sounds daunting, you may want to opt for a fat burner with fewer pills per serving.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Leanbean fat burner seems a little low in green coffee extract and raspberry ketones, but we were pretty impressed. It contains a small amount of natural caffeine — 50 milligrams — which is less than a cup of coffee.
Who Should Buy Leanbean
- People who have trouble with their appetite during weight loss, LeanBean has a strong emphasis on this aspect.
- Anybody who likes cayenne, garcinia Cambogia, turmeric, or green tea extract — these popular fat burner ingredients are well dosed in LeanBean.
- Those looking to suppress appetite as their main way of losing weight and burning fat.
- People with a sensitivity to caffeine. The amount found in LeanBean is less than 10 percent of a small cup of coffee, but it’s worth mentioning.
- Folks who like green coffee and raspberry ketones, it’s a little low on these ingredients.
- Those who don’t want to take six pills each day.

Best Non-Stim Fat Burner for Sleep
Legion Phoenix Stimulant-Free Fat Burner has a strong ingredient list to potentially help you burn fat, and curb appetite and cravings — but it also includes ingredients that may aid in your sleep and impact your memory of your dreams.
Legion Phoenix Stimulant-Free Fat Burner
Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may aid you in your weight-loss journey. Among the list of ingredients is Caralluma Fimbriata extract (CFE) which has been shown to reduce stress and anxiety in adults (10). When our stress and anxiety are lowered, the outcome may lead to better sleep. Another study found that there is a statistically significant relationship between high stress and poor sleep, meaning it can be extremely helpful to lower stress levels to improve sleep quality (11).
Legion Phoenix
Legion's Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.
CFE comes in at 1,000 mg per serving in the Phoenix blend, making it a helpful ingredient in this toolbox to potentially lower stress and cortisol levels, and lead to better sleep, and in turn, better fat-loss capabilities. This ingredient list also contains 5-HTP, a natural serotonin booster, which can potentially improve mood, lessen anxiety, and give you a better night’s sleep, especially if you suffer from insomnia (12). You’ll have to take three vegetarian capsules for a single serving of this fat burner and it will cost you$1.66 per serving.
Who Should Buy Legion Phoenix Stimulant-Free Fat Burner
- Those who are looking to possibly lower their stress and cortisol levels, and in turn, may end up with a better night’s sleep will appreciate the addition of CFE and 5-HTP in this formula.
- Athletes who want a fat burner with the addition of ingredients such as l-dopa to potentially curb cravings and appetite.
- Anyone who wants ingredients that may help resolve insomnia and boost your mood will like the ingredients list on this product — especially 5-HTP.
- Folks who are looking for a basic formula may want to look elsewhere for a smaller ingredient list.
- Someone looking for a supplement fully geared towards sleep may want to look for a fat burner or another supplement that has sleep at the forefront— this supplement has the added benefit of ingredients that may lead to better sleep, but the focus is generally on fat burning.
- Those who are on a budget can find a less expensive option on this list.

Best Non-Stim Fat Burner To Reduce Cravings
Cravings are one of the forefront issues when it comes to fat loss. This formula contains natural appetite suppressants, which can lead to a decrease in cravings, as well.
Leanbean Fat Burner
The best fat burners, in our opinion, impact fat loss in multiple ways: boosting metabolism, appetite suppression, and increasing energy and focus. Leanbean came out on top because of its potent dosage and research-backed ingredients. This fat burner contains glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism.
Leanbean
This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you'll find 50mg of caffeine for a subtle boost in energy.
Plus, you’ll find vitamins B6 and B12, which can help with your energy throughout the day. This product is marketed to women, but it’s a solid non-stim fat burner across the board — one of the only downsides is that you do have to take six capsules a day for a full dose. It’s also worth noting that this product does contain 50mg of caffeine, which is much less than a single cup of coffee, but not inconsequential.
Who Should Buy Leanbean
- Anyone who wants a variety of ingredients working in concert to increase fat loss and energy expenditure.
- People interested in energy boosters: Vitamins B6 and B12 are key for maintaining normal energy levels.
- Those who find a fat-burner with appetite-suppressing ingredients to be appealing will enjoy this ingredient list.
- Those who don’t want to have to take a lot of pills. Leanbean requires six daily.
- Anecdotally, it might not be ideal for people with very sensitive stomachs as glucomannan can be harsh on some.
- If you want a product free of caffeine entirely, you can find other options on this list that will work for you — this supp contains 50mg of caffeine.

The Benefits of Non-Stim Fat Burner
While there are many potential benefits to supplementing with a fat burner, non-stim fat burners offer their own unique benefits. Whether you’re looking to increase thermogenesis, boost fat oxidation, achieve a higher metabolic rate, decrease appetite, or just avoid the poor sleep that may occur when you take stimulants, we detail each potential benefit below.
Non-Stim Benefits
When you opt for a stim-free fat burner, you choose to forego the caffeine or stimulants that are often utilized as fat-burning ingredients. There are many potential benefits to choosing the non-stim route, and it may be the best choice for you if you enjoy getting your stimulants from a caffeine source like coffee, or if you’re on medications that are already loaded with stimulants. It’s also a great choice for those who are easily affected by stimulants but still want a fat-burning supplement to assist them in their fat-burning quest.
