Category - beta-Hydroxy beta-methylbutyric acid [HMB]

beta-Hydroxy beta-methylbutyric acid [HMB] is a metabolite of the amino acid leucine. Leucine and metabolites of leucine have been reported, by several studies, to inhibit protein degradation, have anabolic properties and lipolytic effects [breakdown of fat]. There are some promising studies in sedentary population, however, its effects in athletes are less clear. Most studies conducted on athletes have reported non-significant gains in muscle mass.
