HMB

  • Heart and Circulatory Health

    High Cholesterol

    Supplementing with HMB, or beta hydroxy-beta-methylbutyrate, is an effective way to lower total and LDL cholesterol.
    High Cholesterol
    ×
    The combined results of nine double-blind trials indicate that supplementing with HMB, or beta hydroxy-beta-methylbutyrate, effectively lowers total and LDL cholesterol.1 All trials used 3 grams per day, taken for three to eight weeks.
  • Weight Management

    Obesity

    HMB may improve muscle growth and overall body composition when combined with an exercise program in people who are not already highly trained athletes.

    Biochemical and animal research show that HMB has a role in protein synthesis and might, therefore, improve muscle growth and overall body composition when given as a supplement. However, double-blind human research suggests that HMB may only be effective when combined with an exercise program in people who are not already highly trained athletes. Double-blind trials found no effect of 3 to 6 grams per day of HMB on body weight, body fat, or overall body composition in weight-training football players or other trained athletes.2,3,4,5,6 However, one double-blind study found that 3 grams per day of HMB increased the amount of body fat lost by 70-year old adults who were participating in a strength-training program for the first time.7 A double-blind study of young men with no strength-training experience reported greater improvements in muscle mass (but not in percentage body fat) when HMB was used in the amount of 17 mg per pound of body weight per day.8 However, another group of men in the same study given twice as much HMB did not experience any changes in body composition.

    Athletic Performance and Improving Body Composition with Strength Training in Untrained People

    HMB, a breakdown product of an essential branched-chain amino acid, has a role in protein synthesis and might, therefore, improve muscle growth and overall body composition. Research suggests it might be effective only when combined with an exercise program in people who are not already highly trained athletes.

    HMB (beta hydroxy-beta-methylbutyrate) is a metabolite (breakdown product) of leucine, one of the essential branched-chain amino acids.  Biochemical and animal research show that HMB has a role in protein synthesis and might, therefore, improve muscle growth and overall body composition when given as a supplement. However, double-blind human research suggests that HMB may only be effective when combined with an exercise program in people who are not already highly trained athletes. Double-blind trials found no effect of 3 to 6 grams per day of HMB on body weight, body fat, or overall body composition in weight-training football players or other trained athletes.9,10,11,12,13 However, one double-blind study found that 3 grams per day of HMB increased the amount of body fat lost by 70-year old adults who were participating in a strength-training program for the first time.14 A double-blind study of young men with no strength-training experience reported greater improvements in muscle mass (but not in percentage body fat) when HMB was used in the amount of 17 mg per pound of body weight per day.15 However, another group of men in the same study given twice as much HMB did not experience any changes in body composition.

    HIV and AIDS Support and Preservation of Lean Body Mass

    The combination of glutamine, arginine, and HMB may prevent loss of lean body mass in people with AIDS-associated wasting.

    The combination of glutamine, arginine, and the amino acid derivative, hydroxymethylbutyrate (HMB), may prevent loss of lean body mass in people with AIDS-associated wasting. In a double-blind trial, AIDS patients who had lost 5% of their body weight in the previous three months received either placebo or a nutrient mixture containing 1.5 grams of HMB, 7 grams of L-glutamine, and 7 grams of L-arginine twice daily for eight weeks.16 Those supplemented with placebo gained an average of 0.37 pounds, mostly fat, but lost lean body mass. Those taking the nutrient mixture gained an average of 3 pounds, 85% of which was lean body weight.

What Are Star Ratings?
×
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
