There are a lot of thermogenic fat burners on the market, most of them making pretty extravagant claims about their ability to get you ripped. Few manufacturers offer genuine independent peer-reviewed research to back their claims, so when one does, it makes reviewers like me sit up and pay attention. That's why Burn XT by Jacked Factory came on my radar.
Burn XT claims to have real, specific research to support its ability to act as a thermogenic weight loss and appetite suppressant supplement. So, how effective is it? Does the research stack up, or is it merely smokescreen noise to push a product? In this Burn XT thermogenic fat burner review, we discover whether this product really does what it claims.
Thermogenic Fat Burner
As one of few weight loss supplements for women and men that has been clinically shown to increase energy, focus, and metabolic rate, Burn-XT has set a new precedent for weight-loss...
What is Burn XT?
Burn XT is a thermogenic fat burner and appetitive suppressant manufactured by Jacked Factory. The company has been in existence since 2013 and has established itself as a popular player in the gym supplement market.
Thermogenesis is the process by which heat is produced in the body. This increases the core body temperature, resulting in increased energy and fat burn. Burn XT includes such proven thermogenic ingredients as caffeine anhydrous and Capsimax cayenne pepper fruit extract. There are, however, no ingredients that are directly related to appetite suppression.

Overall Score: 5.0
Burn XT is primarily a thermogenic fat burner. It's got two of the most well-regarded thermogenic boosters and provides them in decent quantities. As mentioned in the introduction, there is also a peer-reviewed independent study on the effectiveness of Burn XT.
A 2023 study was published in the Journal of the International Society of Sports Nutrition. The study analyzed the effectiveness of Burn XT in increasing energy burn; Results determined that the supplement was able to boost energy by 150 calories over three hours. At that rate, you would lose a pound of fat every twenty-three days. That is assuming, of course, that the calorie burn is consistent over that period of time. However, this study does provide a solid basis showing that Burn XT will achieve some level of calorie burn.¹
There is no evidence that Burn XT acts as an appetite suppressant. The label is conspicuously absent of any of the most well-established hunger suppressants like glucomannan or 5-HTP. Burn XT does contain 270 mg of caffeine anhydrous per two-capsule dose. This may be a problem for people who are sensitive to caffeine.
I've personally taken Burn XT over a period of 12 weeks while I was training in my home gym during the COVID lockdowns. At the time, I was following an intermittent fasting diet (16/8) and training daily with weights and cardio on the Ski-erg. My body fat percentage dropped by 1.5% over the three months, but I ascribe that more to the dieting and exercise-induced calorie deficit than the thermogenic effect produced by Burn XT. I did not experience any significant appetite suppressant effect from taking Burn XT.
At the end of the day, Burn XT ranks as a middle-of-the-road thermogenic fat burner. Its five ingredients will give you a slight fat loss boost, but here are other products out there that include more ingredients and work through a more significant number of fat-burning mechanisms to help you achieve your weight loss goals. Check our three alternatives to Burn XT section below for some great options.
Overall Verdict: PASS

+Proven thermogenic ingredients
+Well dosed

5 Burn XT Ingredients
There are just five active ingredients in Burn XT. Here's an overview of each compound, along with its dosage. It should be noted that the listed dosages are per capsule, and serving sizes may vary. Jacked Factory recommends taking two capsules per day.
1. Acetyl-L-Carnitine - 350 mg
Acetyl-L-carnitine (ALCAR) is a naturally occurring amino acid derivative that assists with the transportation of fatty acids into the mitochondria to be used for energy.
ALCAR may also enhance exercise performance by increasing energy output and decreasing workout fatigue. Making it easier to exercise can indirectly help with weight loss.
ALCAR may also have cognitive benefits. As such, it might enhance one's capacity for concentration, memory, and general brain function. ALCAR can help people stay focused on their exercise objectives and make healthier decisions by increasing cognitive function, which may help with weight loss.
ALCAR is typically taken at a dosage of 500–2,000 mg per day in a dose. You will be ingesting 700 mg daily when taken at the recommended dosage.²
We've taken a deeper look at if L-Carnitine is good for weight loss.
2. Green Tea Extract - 225 mg
Green tea extract contains catechins called epigallocatechin gallate (EGCG), which have been shown to promote a thermogenic effect that causes the body to expend more calories. This extract may also promote fat oxidation, the process by which stored fats are broken down to produce energy.³
Green tea extract contains caffeine, which stimulates the central nervous system and boosts metabolism. This also increases fat burning, helping achieve the daily caloric deficit essential for fat loss.
The recommended green tea extract for fat loss is 250-500 mg per day, so the 500 mg you get when taking two tablets of Burn XT is right up there.
?For an even further analysis, read our article on if green tea is good for weight loss.
3. Caffeine Anhydrous - 135 mg
Caffeine anhydrous is a concentrated form of caffeine that promotes a thermogenic effect while also stimulating the central nervous system, resulting in increased heart rate and greater energy expenditure. Caffeine may also promote lipolysis or the breakdown of stored fat into energy. It does this by stimulating the release of fatty acids into the bloodstream.?
Caffeine anhydrous acts as an exercise stimulant, reducing fatigue and providing a quick energy surge. As a result, you may be able to sustain your fat-burning workouts for longer and do them with greater intensity.
The 270 mg dosage from taking two capsules of Burn XT is considered to be within the safe range for most people. However, people who are sensitive to caffeine may suffer such adverse reactions as jitters, increased heart rate, and sleeping difficulty at this dosage.
?If you're one of the people who are caffeine sensitive, check out our list of the Best Non-Stimulant Fat Burners.
4. Capsimax® - 25 mg
Capsimax® is a patented extract of capsicum, the active ingredient in chili peppers. Capsimax includes capsaicinoids, particularly capsaicin, which are thought to contribute to its ability to burn fat. Capsimax is well-known for its thermogenic properties. It has been demonstrated that capsaicin increases thermogenesis, increasing energy expenditure and potentially promoting fat burning.?
Capsaicin has been found to improve lipolysis by encouraging the release of fatty acids from adipose tissue, enabling them to be used as a source of energy during exercise.
Capsimax may also raise the metabolic rate by triggering specific bodily receptors, such as transient receptor potential vanilloid 1 (TRPV1) receptors. This might help in weight loss efforts by increasing energy expenditure.
The 50 mg of Capsimax® you get from taking two capsules of Burn XT is within the typical range for Capsimax® supplementation.
5. Bioperine® - 2.5 mg
The fruit of the Piper nigrum plant is used to make Bioperine®, sometimes referred to as black pepper extract. It is frequently included in dietary supplements to improve the bioavailability and absorption of other substances. Although it doesn't directly aid in burning fat, it might support the effectiveness of the other ingredients in a Burn XT.
A dosage of 5 mg is typically used in weight loss supplements.
Burn XT Claimed Benefits
Jacked Factory makes a number of bold claims about Burn XT in its marketing. In addition to claiming that it is the fastest-growing fat burner in today's market, they also assert that it produces the following effects:
1. Boosts metabolism
Metabolism is a collective term referring to the myriad complex processes that take place within us to convert food into energy and the essential molecules that our bodies need. The more calories you burn at rest, the higher your metabolism will be and the more likely you'll be to achieve a daily caloric deficit.
2. Increases energy
By enhancing the process by which stored body fat is broken down into energy, Burn XT claims to provide its users with an energy boost. This helps power the user through fat-burning workouts, offset fatigue, and get through the day with more vigor.
3. Supports weight loss
By boosting the metabolism, increasing energy, promoting fat oxidation and lipolysis, and supporting workout performance, Burn XT claims to be able to help you achieve your weight loss goals. An extrapolation from the 2023 study mentioned earlier suggests a modest amount of weight loss, at the rate of a pound every 23 days, may be able to be achieved. To produce faster results, you should accompany your Burn XT supplementation with a calorie d]reduced diet and regular exercise.
4. Jumpstarts thermogenesis
Including such ingredients as Acetyl-L-carnitine, green tea extract, and caffeine anhydrous is claimed to promote a thermogenic effect by which the body's internal temperature rises. The body reacts by using more energy to bring the temperature back down to a state of homeostasis. The increased calorie burn that results may help with fat loss.

Side Effects of Burn XT
Burn XT is a natural supplement that contains well-researched ingredients. As a result, it is considered to be safe for the general population. However, people who are sensitive to caffeine may react badly to its 270 mg caffeine dosage. Side effects may include jitters, an energy crash, increased heart rate, and sleeping problems.
Some people may experience minor and usually temporary side effects of taking Burn XT, such as stomach upset, belching, gas, and diarrhea.
Real customer reviews of Burn XT
Burn XT has an average rating of 3.8 stars based on more than 73000 ratings on Amazon. Other sites give it around a 60% positive rating. The general consensus of Burn XT reviews is that Burn XT provides a mild boost to your weight loss when taken along with a reduced-calorie diet and exercise. However, a number of reviewers mention that it does not seem to have any appetite-suppressing effect.
Here are a couple of typical user reviews, one from Amazon and the other from Reddit:
How to take Burn XT?
Jacked Factory recommends taking two Burn XT capsules with water.
When to take Burn XT?
Burn XT should be taken first thing in the morning, before breakfast. If you choose, you can take another two capsules 5-6 hours later.
Who should take Burn XT?
Burn XT should be taken by people who are already following a calorie-restricted diet and who aim to achieve a daily caloric deficit to achieve long-term fat loss. They should also be doing a combination of resistance and cardio exercise to promote their body transformation goals.
Where to buy Burn XT?
Burn XT can be purchased from the official Jacked Factory website; it is also available from Amazon and other selected third-party retailers.
3 Alternatives to Burn XT
The thermogenic fat burner market is crowded, so it can be hard to identify the best from the rest. Here are three alternatives to Burn XT that I've studied in depth, have used personally, and recommend to my personal training clients ...
1. PhenQ
PhenQ is a very popular multi-faceted weight loss supplement manufactured by Wolfson Berg Ltd. It includes a number of compounds designed to speed up metabolism, reduce hunger, increase energy, and improve fat burning.
By taking a multi-faceted strategy, PhenQ sets itself apart from competing weight loss products. These include fat burning, hunger suppression, and energy enhancement. This is also a thermogenic fat burner, containing ingredients such as caffeine and capsicum extract that elevate the body temperature, leading to increased calorie fat burning.
Chromium picolinate and nopal are two ingredients in PhenQ that help suppress appetite and lessen snacking, which supports overall calorie restriction. PhenQ also contains A Lacys Reset®, a proprietary combination of alpha-lipoic acid and cysteine, which may help prevent the development of new fat cells and encourage the oxidation of existing fat.
PhenQ contains substances like caffeine and L-carnitine fumarate to boost energy levels and fight weariness, enabling people to stay active and involved in physical activities. This is done to counterbalance the probable energy reduction during calorie restriction. The combination of L-carnitine fumarate and a-Lacys Reset® may also improve mood and general well-being.
PhenQ is manufactured in GMP-approved facilities, ensuring adherence to strict production standards.

2. Instant Knockout
Instant Knockout is a potent fat burner that was initially created for professional boxers and mixed martial artists. It has since garnered popularity among fitness fans for its alleged capacity to improve body composition overall, increase energy levels, and promote fat burning.
Green tea extract, cayenne pepper, and caffeine are among the ingredients in Instant Knockout that work together to promote thermogenesis. These substances increase the core body temperature, which increases metabolic rate and calorie expenditure.
Ingredients, including glucomannan and green tea extract, can enhance calorie restriction by promoting feelings of fullness and suppressing hunger. Instant Knockout combines caffeine anhydrous and other natural stimulants to fight fatigue and sustain energy levels during times of calorie restriction. These ingredients provide an energy boost that helps you remain focused and active during your weight loss workouts.
Instant Knockout contains ingredients, including piperine and green tea extract, which are said to enhance metabolism and encourage fat burning. These compounds are intended to improve the body's capacity to use fat stores as a fuel source.
Instant Knockout is produced in facilities that have received FDA approval, guaranteeing that strict quality and safety guidelines are followed. The manufacturer instills trust in the product's efficacy and safety by being open and honest about its contents and dosages.
Instant Knockout is normally taken four times per day to maximize its fat-burning effects.

3. PHEN24
PHEN24 sets itself apart in the fat-burning market by providing a daytime and nighttime dosage to help with weight loss efforts 24 hours per day. It is designed to tackle different facets of weight management, such as improving metabolism, curbing hunger, and getting adequate sleep.
PHEN24 comes in two different formulations, one for usage during the day and the other at night. The daytime recipe seeks to increase metabolism, promote fat burning, and increase energy levels. The nighttime blend is designed to promote better sleep, control nightly cravings, and support a healthy metabolism while you're sleeping.
Caffeine, guarana extract, and cayenne powder are among the substances in PHEN24's daytime formula that can improve energy expenditure, thermogenesis, and fat oxidation. These substances rev up the body's metabolic functions, encouraging the use of stored fat as fuel.
The daytime formula also contains glucomannan, a dietary fiber recognized for its ability to control hunger. It also includes guarana extract, which may promote fat burning by assisting people in staying concentrated and involved in physical activity throughout the day.
Griffonia extract and hops extract are two components in the PHEN24 nighttime formula that encourage calm and enhance sleep. Being well-rested is essential for weight loss because it promotes hormonal harmony, hunger control, and general well-being.

Burn XT FAQS
Does Burn XT really work?
Burn XT works in terms of helping to promote fat loss. The degree to which it does so, however, is debatable. According to a 2023 research study, it may achieve a fat loss rate of one pound in 23 days. Suppose your fat loss goal is one pound per week, achieved by a combination of calorie restriction, exercise, and supplementation. In that case, you can see that Burn XT will have a minimal effect, even given the best-case scenario.
Is Burn XT safe?
Yes, Burn XT is considered to be a safe supplement. It contains five all-natural, well-researched ingredients. Each of these ingredients is dosed within clinical guidelines. The only proviso is that people sensitive to caffeine may find the 270 mg dosage too much, producing side effects like jitters, sleep disturbance, and increased heart rate.
Does Burn XT raise blood pressure?
Burn XT does not raise most people's blood pressure when taken at the recommended dosage of two capsules per day. Once again, however, people who are sensitive to caffeine may experience an increase in blood pressure. If you take blood pressure medication, consult your health care professional before taking Burn XT.
Is Burn XT worth it?
Whether Burn XT is worth it is an individual decision. Based on my experience as a personal trainer and my use of many fat burner supplements, I believe that the very minimal best-case scenario fat loss you can achieve with Burn XT, based on research Jacked Factory themselves authorized, does not make it worth the money.
Summary
In this Burn XT review, we have found that Burn XT is a well-established thermogenic fat burner that promises to promote weight loss through increased metabolism and appetite suppression. It stands out due to the fact that there is an independent research study providing an objective analysis of its effectiveness. Unfortunately, this research shows a very modest weight loss. There is also no evidence that Burn XT provides any significant appetite-suppressing benefits.
Other thermogenic fat burners are available that include other fat loss mechanisms and provide a wider range of research-backed ingredients that represent better value for money. Each of the three profiled alternatives to Burn XT - PhenQ, Instant Knockout, and Phen24 - is recommended by SET FOR SET in preference to Burn XT.

5 Burn XT Ingredients
There are just five active ingredients in Burn XT. Here's an overview of each compound, along with its dosage. It should be noted that the listed dosages are per capsule, and serving sizes may vary. Jacked Factory recommends taking two capsules per day.
1. Acetyl-L-Carnitine - 350 mg
Acetyl-L-carnitine (ALCAR) is a naturally occurring amino acid derivative that assists with the transportation of fatty acids into the mitochondria to be used for energy.
ALCAR may also enhance exercise performance by increasing energy output and decreasing workout fatigue. Making it easier to exercise can indirectly help with weight loss.
ALCAR may also have cognitive benefits. As such, it might enhance one's capacity for concentration, memory, and general brain function. ALCAR can help people stay focused on their exercise objectives and make healthier decisions by increasing cognitive function, which may help with weight loss.
ALCAR is typically taken at a dosage of 500–2,000 mg per day in a dose. You will be ingesting 700 mg daily when taken at the recommended dosage.²
We've taken a deeper look at if L-Carnitine is good for weight loss.
2. Green Tea Extract - 225 mg
Green tea extract contains catechins called epigallocatechin gallate (EGCG), which have been shown to promote a thermogenic effect that causes the body to expend more calories. This extract may also promote fat oxidation, the process by which stored fats are broken down to produce energy.³
Green tea extract contains caffeine, which stimulates the central nervous system and boosts metabolism. This also increases fat burning, helping achieve the daily caloric deficit essential for fat loss.
The recommended green tea extract for fat loss is 250-500 mg per day, so the 500 mg you get when taking two tablets of Burn XT is right up there.
?For an even further analysis, read our article on if green tea is good for weight loss.
3. Caffeine Anhydrous - 135 mg
Caffeine anhydrous is a concentrated form of caffeine that promotes a thermogenic effect while also stimulating the central nervous system, resulting in increased heart rate and greater energy expenditure. Caffeine may also promote lipolysis or the breakdown of stored fat into energy. It does this by stimulating the release of fatty acids into the bloodstream.?
Caffeine anhydrous acts as an exercise stimulant, reducing fatigue and providing a quick energy surge. As a result, you may be able to sustain your fat-burning workouts for longer and do them with greater intensity.
The 270 mg dosage from taking two capsules of Burn XT is considered to be within the safe range for most people. However, people who are sensitive to caffeine may suffer such adverse reactions as jitters, increased heart rate, and sleeping difficulty at this dosage.

4. Capsimax® - 25 mg
Capsimax® is a patented extract of capsicum, the active ingredient in chili peppers. Capsimax includes capsaicinoids, particularly capsaicin, which are thought to contribute to its ability to burn fat. Capsimax is well-known for its thermogenic properties. It has been demonstrated that capsaicin increases thermogenesis, increasing energy expenditure and potentially promoting fat burning.?

The 50 mg of Capsimax® you get from taking two capsules of Burn XT is within the typical range for Capsimax® supplementation.
5. Bioperine® - 2.5 mg
The fruit of the Piper nigrum plant is used to make Bioperine®, sometimes referred to as black pepper extract. It is frequently included in dietary supplements to improve the bioavailability and absorption of other substances. Although it doesn't directly aid in burning fat, it might support the effectiveness of the other ingredients in a Burn XT.

Green tea extract, cayenne pepper, and caffeine are among the ingredients in Instant Knockout that work together to promote thermogenesis. These substances increase the core body temperature, which increases metabolic rate and calorie expenditure.
Ingredients, including glucomannan and green tea extract, can enhance calorie restriction by promoting feelings of fullness and suppressing hunger. Instant Knockout combines caffeine anhydrous and other natural stimulants to fight fatigue and sustain energy levels during times of calorie restriction. These ingredients provide an energy boost that helps you remain focused and active during your weight loss workouts.
Instant Knockout contains ingredients, including piperine and green tea extract, which are said to enhance metabolism and encourage fat burning. These compounds are intended to improve the body's capacity to use fat stores as a fuel source.
Instant Knockout is produced in facilities that have received FDA approval, guaranteeing that strict quality and safety guidelines are followed. The manufacturer instills trust in the product's efficacy and safety by being open and honest about its contents and dosages.
Instant Knockout is normally taken four times per day to maximize its fat-burning effects.

3. PHEN24
PHEN24 sets itself apart in the fat-burning market by providing a daytime and nighttime dosage to help with weight loss efforts 24 hours per day. It is designed to tackle different facets of weight management, such as improving metabolism, curbing hunger, and getting adequate sleep.
PHEN24 comes in two different formulations, one for usage during the day and the other at night. The daytime recipe seeks to increase metabolism, promote fat burning, and increase energy levels. The nighttime blend is designed to promote better sleep, control nightly cravings, and support a healthy metabolism while you're sleeping.
Caffeine, guarana extract, and cayenne powder are among the substances in PHEN24's daytime formula that can improve energy expenditure, thermogenesis, and fat oxidation. These substances rev up the body's metabolic functions, encouraging the use of stored fat as fuel.
The daytime formula also contains glucomannan, a dietary fiber recognized for its ability to control hunger. It also includes guarana extract, which may promote fat burning by assisting people in staying concentrated and involved in physical activity throughout the day.
Griffonia extract and hops extract are two components in the PHEN24 nighttime formula that encourage calm and enhance sleep. Being well-rested is essential for weight loss because it promotes hormonal harmony, hunger control, and general well-being.

Burn XT FAQS
Does Burn XT really work?
Burn XT works in terms of helping to promote fat loss. The degree to which it does so, however, is debatable. According to a 2023 research study, it may achieve a fat loss rate of one pound in 23 days. Suppose your fat loss goal is one pound per week, achieved by a combination of calorie restriction, exercise, and supplementation. In that case, you can see that Burn XT will have a minimal effect, even given the best-case scenario.
Is Burn XT safe?
Yes, Burn XT is considered to be a safe supplement. It contains five all-natural, well-researched ingredients. Each of these ingredients is dosed within clinical guidelines. The only proviso is that people sensitive to caffeine may find the 270 mg dosage too much, producing side effects like jitters, sleep disturbance, and increased heart rate.
Does Burn XT raise blood pressure?
Burn XT does not raise most people's blood pressure when taken at the recommended dosage of two capsules per day. Once again, however, people who are sensitive to caffeine may experience an increase in blood pressure. If you take blood pressure medication, consult your health care professional before taking Burn XT.
Is Burn XT worth it?
Whether Burn XT is worth it is an individual decision. Based on my experience as a personal trainer and my use of many fat burner supplements, I believe that the very minimal best-case scenario fat loss you can achieve with Burn XT, based on research Jacked Factory themselves authorized, does not make it worth the money.
Summary
In this Burn XT review, we have found that Burn XT is a well-established thermogenic fat burner that promises to promote weight loss through increased metabolism and appetite suppression. It stands out due to the fact that there is an independent research study providing an objective analysis of its effectiveness. Unfortunately, this research shows a very modest weight loss. There is also no evidence that Burn XT provides any significant appetite-suppressing benefits.
Other thermogenic fat burners are available that include other fat loss mechanisms and provide a wider range of research-backed ingredients that represent better value for money. Each of the three profiled alternatives to Burn XT - PhenQ, Instant Knockout, and Phen24 - is recommended by SET FOR SET in preference to Burn XT.

Burn XT claims to have real, specific research to support its ability to act as a thermogenic weight loss and appetite suppressant supplement. So, how effective is it? Does the research stack up, or is it merely smokescreen noise to push a product? In this Burn XT thermogenic fat burner review, we discover whether this product really does what it claims.
Thermogenic Fat Burner
As one of few weight loss supplements for women and men that has been clinically shown to increase energy, focus, and metabolic rate, Burn-XT has set a new precedent for weight-loss...
What is Burn XT?
Burn XT is a thermogenic fat burner and appetitive suppressant manufactured by Jacked Factory. The company has been in existence since 2013 and has established itself as a popular player in the gym supplement market.
Thermogenesis is the process by which heat is produced in the body. This increases the core body temperature, resulting in increased energy and fat burn. Burn XT includes such proven thermogenic ingredients as caffeine anhydrous and Capsimax cayenne pepper fruit extract. There are, however, no ingredients that are directly related to appetite suppression.

Overall Score: 5.0
Burn XT is primarily a thermogenic fat burner. It's got two of the most well-regarded thermogenic boosters and provides them in decent quantities. As mentioned in the introduction, there is also a peer-reviewed independent study on the effectiveness of Burn XT.
A 2023 study was published in the Journal of the International Society of Sports Nutrition. The study analyzed the effectiveness of Burn XT in increasing energy burn; Results determined that the supplement was able to boost energy by 150 calories over three hours. At that rate, you would lose a pound of fat every twenty-three days. That is assuming, of course, that the calorie burn is consistent over that period of time. However, this study does provide a solid basis showing that Burn XT will achieve some level of calorie burn.¹
There is no evidence that Burn XT acts as an appetite suppressant. The label is conspicuously absent of any of the most well-established hunger suppressants like glucomannan or 5-HTP. Burn XT does contain 270 mg of caffeine anhydrous per two-capsule dose. This may be a problem for people who are sensitive to caffeine.
I've personally taken Burn XT over a period of 12 weeks while I was training in my home gym during the COVID lockdowns. At the time, I was following an intermittent fasting diet (16/8) and training daily with weights and cardio on the Ski-erg. My body fat percentage dropped by 1.5% over the three months, but I ascribe that more to the dieting and exercise-induced calorie deficit than the thermogenic effect produced by Burn XT. I did not experience any significant appetite suppressant effect from taking Burn XT.
At the end of the day, Burn XT ranks as a middle-of-the-road thermogenic fat burner. Its five ingredients will give you a slight fat loss boost, but here are other products out there that include more ingredients and work through a more significant number of fat-burning mechanisms to help you achieve your weight loss goals. Check our three alternatives to Burn XT section below for some great options.
Overall Verdict: PASS
Pros
+Proven thermogenic ingredients
+Well dosed

-Not suitable for people who are sensitive to caffeine
5 Burn XT Ingredients
There are just five active ingredients in Burn XT. Here's an overview of each compound, along with its dosage. It should be noted that the listed dosages are per capsule, and serving sizes may vary. Jacked Factory recommends taking two capsules per day.
1. Acetyl-L-Carnitine - 350 mg
Acetyl-L-carnitine (ALCAR) is a naturally occurring amino acid derivative that assists with the transportation of fatty acids into the mitochondria to be used for energy.
ALCAR may also enhance exercise performance by increasing energy output and decreasing workout fatigue. Making it easier to exercise can indirectly help with weight loss.
ALCAR may also have cognitive benefits. As such, it might enhance one's capacity for concentration, memory, and general brain function. ALCAR can help people stay focused on their exercise objectives and make healthier decisions by increasing cognitive function, which may help with weight loss.
ALCAR is typically taken at a dosage of 500–2,000 mg per day in a dose. You will be ingesting 700 mg daily when taken at the recommended dosage.²
We've taken a deeper look at if L-Carnitine is good for weight loss.
2. Green Tea Extract - 225 mg
Green tea extract contains catechins called epigallocatechin gallate (EGCG), which have been shown to promote a thermogenic effect that causes the body to expend more calories. This extract may also promote fat oxidation, the process by which stored fats are broken down to produce energy.³
Green tea extract contains caffeine, which stimulates the central nervous system and boosts metabolism. This also increases fat burning, helping achieve the daily caloric deficit essential for fat loss.
The recommended green tea extract for fat loss is 250-500 mg per day, so the 500 mg you get when taking two tablets of Burn XT is right up there.
?For an even further analysis, read our article on if green tea is good for weight loss.
3. Caffeine Anhydrous - 135 mg
Caffeine anhydrous is a concentrated form of caffeine that promotes a thermogenic effect while also stimulating the central nervous system, resulting in increased heart rate and greater energy expenditure. Caffeine may also promote lipolysis or the breakdown of stored fat into energy. It does this by stimulating the release of fatty acids into the bloodstream.?
Caffeine anhydrous acts as an exercise stimulant, reducing fatigue and providing a quick energy surge. As a result, you may be able to sustain your fat-burning workouts for longer and do them with greater intensity.
The 270 mg dosage from taking two capsules of Burn XT is considered to be within the safe range for most people. However, people who are sensitive to caffeine may suffer such adverse reactions as jitters, increased heart rate, and sleeping difficulty at this dosage.
?If you're one of the people who are caffeine sensitive, check out our list of the Best Non-Stimulant Fat Burners.
4. Capsimax® - 25 mg
Capsimax® is a patented extract of capsicum, the active ingredient in chili peppers. Capsimax includes capsaicinoids, particularly capsaicin, which are thought to contribute to its ability to burn fat. Capsimax is well-known for its thermogenic properties. It has been demonstrated that capsaicin increases thermogenesis, increasing energy expenditure and potentially promoting fat burning.?
Capsaicin has been found to improve lipolysis by encouraging the release of fatty acids from adipose tissue, enabling them to be used as a source of energy during exercise.
Capsimax may also raise the metabolic rate by triggering specific bodily receptors, such as transient receptor potential vanilloid 1 (TRPV1) receptors. This might help in weight loss efforts by increasing energy expenditure.
The 50 mg of Capsimax® you get from taking two capsules of Burn XT is within the typical range for Capsimax® supplementation.
5. Bioperine® - 2.5 mg
The fruit of the Piper nigrum plant is used to make Bioperine®, sometimes referred to as black pepper extract. It is frequently included in dietary supplements to improve the bioavailability and absorption of other substances. Although it doesn't directly aid in burning fat, it might support the effectiveness of the other ingredients in a Burn XT.
A dosage of 5 mg is typically used in weight loss supplements.
Burn XT Claimed Benefits
Jacked Factory makes a number of bold claims about Burn XT in its marketing. In addition to claiming that it is the fastest-growing fat burner in today's market, they also assert that it produces the following effects:
1. Boosts metabolism
Metabolism is a collective term referring to the myriad complex processes that take place within us to convert food into energy and the essential molecules that our bodies need. The more calories you burn at rest, the higher your metabolism will be and the more likely you'll be to achieve a daily caloric deficit.
2. Increases energy
By enhancing the process by which stored body fat is broken down into energy, Burn XT claims to provide its users with an energy boost. This helps power the user through fat-burning workouts, offset fatigue, and get through the day with more vigor.
3. Supports weight loss
By boosting the metabolism, increasing energy, promoting fat oxidation and lipolysis, and supporting workout performance, Burn XT claims to be able to help you achieve your weight loss goals. An extrapolation from the 2023 study mentioned earlier suggests a modest amount of weight loss, at the rate of a pound every 23 days, may be able to be achieved. To produce faster results, you should accompany your Burn XT supplementation with a calorie d]reduced diet and regular exercise.
4. Jumpstarts thermogenesis
Including such ingredients as Acetyl-L-carnitine, green tea extract, and caffeine anhydrous is claimed to promote a thermogenic effect by which the body's internal temperature rises. The body reacts by using more energy to bring the temperature back down to a state of homeostasis. The increased calorie burn that results may help with fat loss.

Side Effects of Burn XT
Burn XT is a natural supplement that contains well-researched ingredients. As a result, it is considered to be safe for the general population. However, people who are sensitive to caffeine may react badly to its 270 mg caffeine dosage. Side effects may include jitters, an energy crash, increased heart rate, and sleeping problems.
Some people may experience minor and usually temporary side effects of taking Burn XT, such as stomach upset, belching, gas, and diarrhea.
Real customer reviews of Burn XT
Burn XT has an average rating of 3.8 stars based on more than 73000 ratings on Amazon. Other sites give it around a 60% positive rating. The general consensus of Burn XT reviews is that Burn XT provides a mild boost to your weight loss when taken along with a reduced-calorie diet and exercise. However, a number of reviewers mention that it does not seem to have any appetite-suppressing effect.
Here are a couple of typical user reviews, one from Amazon and the other from Reddit:
How to take Burn XT?
Jacked Factory recommends taking two Burn XT capsules with water.
When to take Burn XT?
Burn XT should be taken first thing in the morning, before breakfast. If you choose, you can take another two capsules 5-6 hours later.
Who should take Burn XT?
Burn XT should be taken by people who are already following a calorie-restricted diet and who aim to achieve a daily caloric deficit to achieve long-term fat loss. They should also be doing a combination of resistance and cardio exercise to promote their body transformation goals.
Where to buy Burn XT?
Burn XT can be purchased from the official Jacked Factory website; it is also available from Amazon and other selected third-party retailers.
3 Alternatives to Burn XT
The thermogenic fat burner market is crowded, so it can be hard to identify the best from the rest. Here are three alternatives to Burn XT that I've studied in depth, have used personally, and recommend to my personal training clients ...
1. PhenQ
PhenQ is a very popular multi-faceted weight loss supplement manufactured by Wolfson Berg Ltd. It includes a number of compounds designed to speed up metabolism, reduce hunger, increase energy, and improve fat burning.
By taking a multi-faceted strategy, PhenQ sets itself apart from competing weight loss products. These include fat burning, hunger suppression, and energy enhancement. This is also a thermogenic fat burner, containing ingredients such as caffeine and capsicum extract that elevate the body temperature, leading to increased calorie fat burning.
Chromium picolinate and nopal are two ingredients in PhenQ that help suppress appetite and lessen snacking, which supports overall calorie restriction. PhenQ also contains A Lacys Reset®, a proprietary combination of alpha-lipoic acid and cysteine, which may help prevent the development of new fat cells and encourage the oxidation of existing fat.
PhenQ contains substances like caffeine and L-carnitine fumarate to boost energy levels and fight weariness, enabling people to stay active and involved in physical activities. This is done to counterbalance the probable energy reduction during calorie restriction. The combination of L-carnitine fumarate and a-Lacys Reset® may also improve mood and general well-being.
PhenQ is manufactured in GMP-approved facilities, ensuring adherence to strict production standards.

5 Burn XT Ingredients
There are just five active ingredients in Burn XT. Here's an overview of each compound, along with its dosage. It should be noted that the listed dosages are per capsule, and serving sizes may vary. Jacked Factory recommends taking two capsules per day.
1. Acetyl-L-Carnitine - 350 mg
Acetyl-L-carnitine (ALCAR) is a naturally occurring amino acid derivative that assists with the transportation of fatty acids into the mitochondria to be used for energy.
ALCAR may also enhance exercise performance by increasing energy output and decreasing workout fatigue. Making it easier to exercise can indirectly help with weight loss.
ALCAR may also have cognitive benefits. As such, it might enhance one's capacity for concentration, memory, and general brain function. ALCAR can help people stay focused on their exercise objectives and make healthier decisions by increasing cognitive function, which may help with weight loss.
ALCAR is typically taken at a dosage of 500–2,000 mg per day in a dose. You will be ingesting 700 mg daily when taken at the recommended dosage.²
We've taken a deeper look at if L-Carnitine is good for weight loss.
2. Green Tea Extract - 225 mg
Green tea extract contains catechins called epigallocatechin gallate (EGCG), which have been shown to promote a thermogenic effect that causes the body to expend more calories. This extract may also promote fat oxidation, the process by which stored fats are broken down to produce energy.³
Green tea extract contains caffeine, which stimulates the central nervous system and boosts metabolism. This also increases fat burning, helping achieve the daily caloric deficit essential for fat loss.
The recommended green tea extract for fat loss is 250-500 mg per day, so the 500 mg you get when taking two tablets of Burn XT is right up there.
?For an even further analysis, read our article on if green tea is good for weight loss.
3. Caffeine Anhydrous - 135 mg
Caffeine anhydrous is a concentrated form of caffeine that promotes a thermogenic effect while also stimulating the central nervous system, resulting in increased heart rate and greater energy expenditure. Caffeine may also promote lipolysis or the breakdown of stored fat into energy. It does this by stimulating the release of fatty acids into the bloodstream.?
Caffeine anhydrous acts as an exercise stimulant, reducing fatigue and providing a quick energy surge. As a result, you may be able to sustain your fat-burning workouts for longer and do them with greater intensity.
The 270 mg dosage from taking two capsules of Burn XT is considered to be within the safe range for most people. However, people who are sensitive to caffeine may suffer such adverse reactions as jitters, increased heart rate, and sleeping difficulty at this dosage.

4. Capsimax® - 25 mg
Capsimax® is a patented extract of capsicum, the active ingredient in chili peppers. Capsimax includes capsaicinoids, particularly capsaicin, which are thought to contribute to its ability to burn fat. Capsimax is well-known for its thermogenic properties. It has been demonstrated that capsaicin increases thermogenesis, increasing energy expenditure and potentially promoting fat burning.?
Capsaicin has been found to improve lipolysis by encouraging the release of fatty acids from adipose tissue, enabling them to be used as a source of energy during exercise.
Capsimax may also raise the metabolic rate by triggering specific bodily receptors, such as transient receptor potential vanilloid 1 (TRPV1) receptors. This might help in weight loss efforts by increasing energy expenditure.
The 50 mg of Capsimax® you get from taking two capsules of Burn XT is within the typical range for Capsimax® supplementation.
5. Bioperine® - 2.5 mg
The fruit of the Piper nigrum plant is used to make Bioperine®, sometimes referred to as black pepper extract. It is frequently included in dietary supplements to improve the bioavailability and absorption of other substances. Although it doesn't directly aid in burning fat, it might support the effectiveness of the other ingredients in a Burn XT.
A dosage of 5 mg is typically used in weight loss supplements.
Burn XT Claimed Benefits
Jacked Factory makes a number of bold claims about Burn XT in its marketing. In addition to claiming that it is the fastest-growing fat burner in today's market, they also assert that it produces the following effects:
1. Boosts metabolism
Metabolism is a collective term referring to the myriad complex processes that take place within us to convert food into energy and the essential molecules that our bodies need. The more calories you burn at rest, the higher your metabolism will be and the more likely you'll be to achieve a daily caloric deficit.
2. Increases energy
By enhancing the process by which stored body fat is broken down into energy, Burn XT claims to provide its users with an energy boost. This helps power the user through fat-burning workouts, offset fatigue, and get through the day with more vigor.
3. Supports weight loss
By boosting the metabolism, increasing energy, promoting fat oxidation and lipolysis, and supporting workout performance, Burn XT claims to be able to help you achieve your weight loss goals. An extrapolation from the 2023 study mentioned earlier suggests a modest amount of weight loss, at the rate of a pound every 23 days, may be able to be achieved. To produce faster results, you should accompany your Burn XT supplementation with a calorie d]reduced diet and regular exercise.
4. Jumpstarts thermogenesis
Including such ingredients as Acetyl-L-carnitine, green tea extract, and caffeine anhydrous is claimed to promote a thermogenic effect by which the body's internal temperature rises. The body reacts by using more energy to bring the temperature back down to a state of homeostasis. The increased calorie burn that results may help with fat loss.

Side Effects of Burn XT
Burn XT is a natural supplement that contains well-researched ingredients. As a result, it is considered to be safe for the general population. However, people who are sensitive to caffeine may react badly to its 270 mg caffeine dosage. Side effects may include jitters, an energy crash, increased heart rate, and sleeping problems.
Some people may experience minor and usually temporary side effects of taking Burn XT, such as stomach upset, belching, gas, and diarrhea.
Real customer reviews of Burn XT
Burn XT has an average rating of 3.8 stars based on more than 73000 ratings on Amazon. Other sites give it around a 60% positive rating. The general consensus of Burn XT reviews is that Burn XT provides a mild boost to your weight loss when taken along with a reduced-calorie diet and exercise. However, a number of reviewers mention that it does not seem to have any appetite-suppressing effect.
Here are a couple of typical user reviews, one from Amazon and the other from Reddit:
How to take Burn XT?
Jacked Factory recommends taking two Burn XT capsules with water.
When to take Burn XT?
Burn XT should be taken first thing in the morning, before breakfast. If you choose, you can take another two capsules 5-6 hours later.
Who should take Burn XT?
Burn XT should be taken by people who are already following a calorie-restricted diet and who aim to achieve a daily caloric deficit to achieve long-term fat loss. They should also be doing a combination of resistance and cardio exercise to promote their body transformation goals.
Where to buy Burn XT?
Burn XT can be purchased from the official Jacked Factory website; it is also available from Amazon and other selected third-party retailers.
3 Alternatives to Burn XT
The thermogenic fat burner market is crowded, so it can be hard to identify the best from the rest. Here are three alternatives to Burn XT that I've studied in depth, have used personally, and recommend to my personal training clients ...
1. PhenQ
PhenQ is a very popular multi-faceted weight loss supplement manufactured by Wolfson Berg Ltd. It includes a number of compounds designed to speed up metabolism, reduce hunger, increase energy, and improve fat burning.
By taking a multi-faceted strategy, PhenQ sets itself apart from competing weight loss products. These include fat burning, hunger suppression, and energy enhancement. This is also a thermogenic fat burner, containing ingredients such as caffeine and capsicum extract that elevate the body temperature, leading to increased calorie fat burning.
Chromium picolinate and nopal are two ingredients in PhenQ that help suppress appetite and lessen snacking, which supports overall calorie restriction. PhenQ also contains A Lacys Reset®, a proprietary combination of alpha-lipoic acid and cysteine, which may help prevent the development of new fat cells and encourage the oxidation of existing fat.
PhenQ contains substances like caffeine and L-carnitine fumarate to boost energy levels and fight weariness, enabling people to stay active and involved in physical activities. This is done to counterbalance the probable energy reduction during calorie restriction. The combination of L-carnitine fumarate and a-Lacys Reset® may also improve mood and general well-being.
PhenQ is manufactured in GMP-approved facilities, ensuring adherence to strict production standards.

2. Instant Knockout
Instant Knockout is a potent fat burner that was initially created for professional boxers and mixed martial artists. It has since garnered popularity among fitness fans for its alleged capacity to improve body composition overall, increase energy levels, and promote fat burning.
Green tea extract, cayenne pepper, and caffeine are among the ingredients in Instant Knockout that work together to promote thermogenesis. These substances increase the core body temperature, which increases metabolic rate and calorie expenditure.
Ingredients, including glucomannan and green tea extract, can enhance calorie restriction by promoting feelings of fullness and suppressing hunger. Instant Knockout combines caffeine anhydrous and other natural stimulants to fight fatigue and sustain energy levels during times of calorie restriction. These ingredients provide an energy boost that helps you remain focused and active during your weight loss workouts.
Instant Knockout contains ingredients, including piperine and green tea extract, which are said to enhance metabolism and encourage fat burning. These compounds are intended to improve the body's capacity to use fat stores as a fuel source.
Instant Knockout is produced in facilities that have received FDA approval, guaranteeing that strict quality and safety guidelines are followed. The manufacturer instills trust in the product's efficacy and safety by being open and honest about its contents and dosages.
Instant Knockout is normally taken four times per day to maximize its fat-burning effects.

3. PHEN24
PHEN24 sets itself apart in the fat-burning market by providing a daytime and nighttime dosage to help with weight loss efforts 24 hours per day. It is designed to tackle different facets of weight management, such as improving metabolism, curbing hunger, and getting adequate sleep.
PHEN24 comes in two different formulations, one for usage during the day and the other at night. The daytime recipe seeks to increase metabolism, promote fat burning, and increase energy levels. The nighttime blend is designed to promote better sleep, control nightly cravings, and support a healthy metabolism while you're sleeping.
Caffeine, guarana extract, and cayenne powder are among the substances in PHEN24's daytime formula that can improve energy expenditure, thermogenesis, and fat oxidation. These substances rev up the body's metabolic functions, encouraging the use of stored fat as fuel.
The daytime formula also contains glucomannan, a dietary fiber recognized for its ability to control hunger. It also includes guarana extract, which may promote fat burning by assisting people in staying concentrated and involved in physical activity throughout the day.
Griffonia extract and hops extract are two components in the PHEN24 nighttime formula that encourage calm and enhance sleep. Being well-rested is essential for weight loss because it promotes hormonal harmony, hunger control, and general well-being.

Burn XT FAQS
Does Burn XT really work?
Burn XT works in terms of helping to promote fat loss. The degree to which it does so, however, is debatable. According to a 2023 research study, it may achieve a fat loss rate of one pound in 23 days. Suppose your fat loss goal is one pound per week, achieved by a combination of calorie restriction, exercise, and supplementation. In that case, you can see that Burn XT will have a minimal effect, even given the best-case scenario.
Is Burn XT safe?
Yes, Burn XT is considered to be a safe supplement. It contains five all-natural, well-researched ingredients. Each of these ingredients is dosed within clinical guidelines. The only proviso is that people sensitive to caffeine may find the 270 mg dosage too much, producing side effects like jitters, sleep disturbance, and increased heart rate.
Does Burn XT raise blood pressure?
Burn XT does not raise most people's blood pressure when taken at the recommended dosage of two capsules per day. Once again, however, people who are sensitive to caffeine may experience an increase in blood pressure. If you take blood pressure medication, consult your health care professional before taking Burn XT.
Is Burn XT worth it?
Whether Burn XT is worth it is an individual decision. Based on my experience as a personal trainer and my use of many fat burner supplements, I believe that the very minimal best-case scenario fat loss you can achieve with Burn XT, based on research Jacked Factory themselves authorized, does not make it worth the money.
Summary
In this Burn XT review, we have found that Burn XT is a well-established thermogenic fat burner that promises to promote weight loss through increased metabolism and appetite suppression. It stands out due to the fact that there is an independent research study providing an objective analysis of its effectiveness. Unfortunately, this research shows a very modest weight loss. There is also no evidence that Burn XT provides any significant appetite-suppressing benefits.
Other thermogenic fat burners are available that include other fat loss mechanisms and provide a wider range of research-backed ingredients that represent better value for money. Each of the three profiled alternatives to Burn XT - PhenQ, Instant Knockout, and Phen24 - is recommended by SET FOR SET in preference to Burn XT.
