What is HMB?
HMB, meaning beta-hydroxy beta-methyl butyrate, is a dietary supplement sometimes used by athletes and bodybuilders. As a leucine metabolite, it reduces muscle protein breakdown while increasing protein synthesis, leading to a net increase in muscle mass.
HMB has been shown to help maintain muscle mass while dieting or during periods of low activity and promote muscle hypertrophy when combined with intense resistance training. We will dig deeper into the specifics later in the article, but for beginners will get the best results using HMB.
What Does HMB Do?
HMB works by reducing muscle cells protein breakdown and promoting protein synthesis. When you exercise, your body degrades muscle proteins, which causes muscular damage and discomfort. HMB helps reduce this muscle protein breakdown by inhibiting certain enzymes that break down muscle proteins1.
In addition to reducing muscle protein breakdown, HMB also increases protein synthesis, which is the process by which the body builds new proteins. This increase in protein synthesis could lead to more muscle mass and improve muscular strength over time.
HMB could also allow for faster recovery and better overall performance. According to research, HMB's anti-inflammatory qualities may aid in the reduction of muscle damage and discomfort following exercise2.
While we need more research to fully dig into the mechanisms behind HMB, its ability to reduce muscle protein breakdown and promote protein synthesis makes it a popular supplement for bodybuilders looking to support muscle growth and recovery.
How Does The Body Create HMB?
As previously stated, HMB is a metabolite of leucine, a branched-chain amino acid in high-protein diets such as beef, poultry, fish, and dairy products. Your body breaks these proteins into amino acids, including leucine.
Once leucine is in the body, it can be used in various ways, including protein synthesis and energy production. A small portion of leucine is also converted into HMB through a series of enzymatic reactions that occur primarily in the liver.
The human body gets all of its HMB from dietary sources of leucine, with roughly five percent of all dietary leucine being converted to HMB3.
While the body does produce some HMB on its own, the amount is relatively small compared to the amounts found in dietary supplements. Most people will want to supplement HMB to get a significant amount.
5 Best HMB Benefits
Looking for more reasons too convince you to take HMB? Here are the five best benefits of beta hydroxy beta methylbutyrate supplements.
1) Increases Lean Body Mass:
Recent research shows that HMB has been shown to help increase muscle growth, specifically in untrained young men4, boosting protein synthesis and improving recovery.
For example, a 2018 study showed HMB supplementation improved work capacity recovery within 24 hours after high-intensity exercise5.
2) Improves Muscle Strength:
Supplementing with HMB can improve strength gains in trained and untrained lifters. A 2009 meta-analysis examined nine studies that included trained and untrained subjects.
Based on the data, HMB offers a clear benefit for lower body strength gains in beginners6. Although the meta-analysis only showed a trivial benefit for trained lifters, some research supports strength gains for everyone.
For instance, one study by Panton and colleagues found that when paired with an exercise regimen, HMB may boost upper body strength and decrease muscle damage regardless of gender or training status7.
3) Reduces Muscle Damage:
HMB has been shown to reduce not only exercise-induced muscle damage but muscle loss from aging as well. In one study, 3g of HMB supplementation following a long run led to decreased creatine phosphokinase and LDH response.
Both are metabolites of muscular breakdown, so a reduction supports the concept that HMB supplementation can slow exercise-induced muscle damage8.
Additionally, HMB can prevent muscle loss in older adults. Another study examined how HMB affects older people after ten days of bed rest. The subjects supplementing with HMB saw less muscle loss than those who didn't take HMB9.
4) Boosts Muscle Protein Synthesis:
HMB activates the body's mTOR enzyme, inducing muscle protein synthesis10. The research is in mice, but it is plausible since HMB is a metabolite of leucine, and leucine is the primary driver of muscle protein synthesis11.
5) Reduces Inflammation:
HMB has anti-inflammatory properties that may help reduce inflammation and muscle soreness caused by intense training. That's great news for muscle recovery!
HMB Side Effects
What sets HMB apart from other supplements is its safety and effectiveness. It has been extensively studied in human trials for decades and is safe for long-term use, with no known adverse effects reported.
However, as with any supplement, dosage is key. Taking between 1 to 3g of HMB per day is recommended in most cases.
What Are HMB Supplements?
HMB supplements are dietary supplements commonly used by athletes and bodybuilders that contain HMB as the main active ingredient. As mentioned, HMB is a naturally occurring compound both found in food and produced in the body as a byproduct of leucine metabolism.
That said, it is much easier to get enough HMB through supplementation. HMB supplements come in various forms, including capsules, tablets, powders, and liquid formulations. You can also get products with HMB with amino acids arginine and glutamine or vitamin D.
Most studies looking at HMB have used the calcium salt of HMB (HMB-Ca). However, another form of HMB, HMB-free acid, has recently taken over as the most popular form.
They are typically taken daily in doses ranging from 1 to 3 grams, although the optimal amount depends on things like body weight and exercise intensity.
Are HMB Supplements Good For Bodybuilders?
Bodybuilders may benefit from supplementing with HMB for several reasons.
First, HMB studies show it supports building muscle by promoting protein synthesis and reducing protein breakdown. Combine more protein generation and less muscle loss with enough time, and you've got a recipe for muscle mass and strength gains.
Moreover, HMB may also help reduce muscle damage and soreness after exercise, allowing for faster recovery and better overall performance. The harder and more often you can train without injury, the better your performance.
Finally, HMB may have anti-inflammatory properties, which help reduce inflammation and oxidative stress, potentially positively impacting overall health and well-being.
Who Should Take HMB Supplements?
Most people can benefit by supplementing with HMB, but there are three groups who will see the best results.
1) Bodybuilders:
As mentioned, HMB supplementation is great for bodybuilders. Competitive bodybuilders often train in catabolic states, and anti-catabolism is one of HMB's best qualities. One user praised HMB's positive effects on their frequent, high-volume training schedule:
"HMB is great for long high intensity workouts with lots of volume. I'm able to recover and grow from 3 hour workouts now, doing ~15 sets per body part and 3 BP per workout (so total 40-45 sets). HMB is more or less useless for low volume work IMO." (source)
As bodybuilders get more training volume than most, a safe and effective supplement like HMB is a great option to improve body composition for anyone looking for that edge over the competition.
2) New Lifters:
New lifters can expect to gain muscle strength, improve body composition, increase muscle mass, and reduce muscle damage with HMB.
In case you didn't notice, beginners' benefits mimic those of advanced bodybuilders, but they're just to a larger degree.
Since beginners typically see more initial muscle damage from lifting, and HMB can suppress muscle damage and muscle protein breakdown, the impact of HMB for muscle growth is more significant.
3) Older Adults:
As we age, muscle mass and strength naturally decline, and HMB can help combat this by reducing protein breakdown and promoting protein synthesis.
Additionally, older lifters often experience more muscle soreness and fatigue from physical exercise than younger lifters. Supplementing with HMB may help reduce muscle damage and soreness after exercise.
Lastly, HMB's anti-inflammatory properties may positively impact overall health and well-being, especially for older lifters at increased risk of age-related health conditions.
Who Shouldn't Take HMB Supplements?
HMB supplements are generally safe for all people. However, there is insufficient research on their safety during pregnancy or breastfeeding, so it's best to avoid them. The same can be said for children, although there shouldn't be any issue.
Lastly, in rare occurrences, some experience GI issues when supplementing with HMB. If that happens, discontinue use or try a lower dose.

What is HMB?
HMB, meaning beta-hydroxy beta-methyl butyrate, is a dietary supplement sometimes used by athletes and bodybuilders. As a leucine metabolite, it reduces muscle protein breakdown while increasing protein synthesis, leading to a net increase in muscle mass.
HMB has been shown to help maintain muscle mass while dieting or during periods of low activity and promote muscle hypertrophy when combined with intense resistance training. We will dig deeper into the specifics later in the article, but for beginners will get the best results using HMB.
What Does HMB Do?
HMB works by reducing muscle cells protein breakdown and promoting protein synthesis. When you exercise, your body degrades muscle proteins, which causes muscular damage and discomfort. HMB helps reduce this muscle protein breakdown by inhibiting certain enzymes that break down muscle proteins1.
In addition to reducing muscle protein breakdown, HMB also increases protein synthesis, which is the process by which the body builds new proteins. This increase in protein synthesis could lead to more muscle mass and improve muscular strength over time.
HMB could also allow for faster recovery and better overall performance. According to research, HMB's anti-inflammatory qualities may aid in the reduction of muscle damage and discomfort following exercise2.
While we need more research to fully dig into the mechanisms behind HMB, its ability to reduce muscle protein breakdown and promote protein synthesis makes it a popular supplement for bodybuilders looking to support muscle growth and recovery.
How Does The Body Create HMB?
As previously stated, HMB is a metabolite of leucine, a branched-chain amino acid in high-protein diets such as beef, poultry, fish, and dairy products. Your body breaks these proteins into amino acids, including leucine.
Once leucine is in the body, it can be used in various ways, including protein synthesis and energy production. A small portion of leucine is also converted into HMB through a series of enzymatic reactions that occur primarily in the liver.
The human body gets all of its HMB from dietary sources of leucine, with roughly five percent of all dietary leucine being converted to HMB3.
While the body does produce some HMB on its own, the amount is relatively small compared to the amounts found in dietary supplements. Most people will want to supplement HMB to get a significant amount.
5 Best HMB Benefits
Looking for more reasons too convince you to take HMB? Here are the five best benefits of beta hydroxy beta methylbutyrate supplements.
1) Increases Lean Body Mass:
Recent research shows that HMB has been shown to help increase muscle growth, specifically in untrained young men4, boosting protein synthesis and improving recovery.
For example, a 2018 study showed HMB supplementation improved work capacity recovery within 24 hours after high-intensity exercise5.
2) Improves Muscle Strength:
Supplementing with HMB can improve strength gains in trained and untrained lifters. A 2009 meta-analysis examined nine studies that included trained and untrained subjects.
Based on the data, HMB offers a clear benefit for lower body strength gains in beginners6. Although the meta-analysis only showed a trivial benefit for trained lifters, some research supports strength gains for everyone.
For instance, one study by Panton and colleagues found that when paired with an exercise regimen, HMB may boost upper body strength and decrease muscle damage regardless of gender or training status7.
3) Reduces Muscle Damage:
HMB has been shown to reduce not only exercise-induced muscle damage but muscle loss from aging as well. In one study, 3g of HMB supplementation following a long run led to decreased creatine phosphokinase and LDH response.
Both are metabolites of muscular breakdown, so a reduction supports the concept that HMB supplementation can slow exercise-induced muscle damage8.
Additionally, HMB can prevent muscle loss in older adults. Another study examined how HMB affects older people after ten days of bed rest. The subjects supplementing with HMB saw less muscle loss than those who didn't take HMB9.
4) Boosts Muscle Protein Synthesis:
HMB activates the body's mTOR enzyme, inducing muscle protein synthesis10. The research is in mice, but it is plausible since HMB is a metabolite of leucine, and leucine is the primary driver of muscle protein synthesis11.
5) Reduces Inflammation:
HMB has anti-inflammatory properties that may help reduce inflammation and muscle soreness caused by intense training. That's great news for muscle recovery!
HMB Side Effects
What sets HMB apart from other supplements is its safety and effectiveness. It has been extensively studied in human trials for decades and is safe for long-term use, with no known adverse effects reported.
However, as with any supplement, dosage is key. Taking between 1 to 3g of HMB per day is recommended in most cases.
What Are HMB Supplements?
HMB supplements are dietary supplements commonly used by athletes and bodybuilders that contain HMB as the main active ingredient. As mentioned, HMB is a naturally occurring compound both found in food and produced in the body as a byproduct of leucine metabolism.
That said, it is much easier to get enough HMB through supplementation. HMB supplements come in various forms, including capsules, tablets, powders, and liquid formulations. You can also get products with HMB with amino acids arginine and glutamine or vitamin D.
Most studies looking at HMB have used the calcium salt of HMB (HMB-Ca). However, another form of HMB, HMB-free acid, has recently taken over as the most popular form.
They are typically taken daily in doses ranging from 1 to 3 grams, although the optimal amount depends on things like body weight and exercise intensity.
Are HMB Supplements Good For Bodybuilders?
Bodybuilders may benefit from supplementing with HMB for several reasons.
First, HMB studies show it supports building muscle by promoting protein synthesis and reducing protein breakdown. Combine more protein generation and less muscle loss with enough time, and you've got a recipe for muscle mass and strength gains.
Moreover, HMB may also help reduce muscle damage and soreness after exercise, allowing for faster recovery and better overall performance. The harder and more often you can train without injury, the better your performance.
Finally, HMB may have anti-inflammatory properties, which help reduce inflammation and oxidative stress, potentially positively impacting overall health and well-being.
Who Should Take HMB Supplements?
Most people can benefit by supplementing with HMB, but there are three groups who will see the best results.
1) Bodybuilders:
As mentioned, HMB supplementation is great for bodybuilders. Competitive bodybuilders often train in catabolic states, and anti-catabolism is one of HMB's best qualities. One user praised HMB's positive effects on their frequent, high-volume training schedule:
"HMB is great for long high intensity workouts with lots of volume. I'm able to recover and grow from 3 hour workouts now, doing ~15 sets per body part and 3 BP per workout (so total 40-45 sets). HMB is more or less useless for low volume work IMO." (source)
As bodybuilders get more training volume than most, a safe and effective supplement like HMB is a great option to improve body composition for anyone looking for that edge over the competition.
2) New Lifters:
New lifters can expect to gain muscle strength, improve body composition, increase muscle mass, and reduce muscle damage with HMB.
In case you didn't notice, beginners' benefits mimic those of advanced bodybuilders, but they're just to a larger degree.
Since beginners typically see more initial muscle damage from lifting, and HMB can suppress muscle damage and muscle protein breakdown, the impact of HMB for muscle growth is more significant.
3) Older Adults:
As we age, muscle mass and strength naturally decline, and HMB can help combat this by reducing protein breakdown and promoting protein synthesis.
Additionally, older lifters often experience more muscle soreness and fatigue from physical exercise than younger lifters. Supplementing with HMB may help reduce muscle damage and soreness after exercise.
Lastly, HMB's anti-inflammatory properties may positively impact overall health and well-being, especially for older lifters at increased risk of age-related health conditions.
Who Shouldn't Take HMB Supplements?
HMB supplements are generally safe for all people. However, there is insufficient research on their safety during pregnancy or breastfeeding, so it's best to avoid them. The same can be said for children, although there shouldn't be any issue.
Lastly, in rare occurrences, some experience GI issues when supplementing with HMB. If that happens, discontinue use or try a lower dose.
