Research published in the Journal of Applied Physiology and other peer reviewed publications has suggested that HMB may have an effect on increasing muscle weight and strength. Three grams of HMB per day can help highly trained muscles combat protein breakdown, assist in muscle repair and support increased endurance.

Beta-hydroxy beta-methylbutyrate (HMB) is an important metabolite of the essential branched chain amino acid (BCAA) L-Leucine. Human and animal studies suggest protein breakdown and support significant increases in muscle strength and size when combined with intense resistance training.
