Beta-Hydroxy-Beta-Methylbutyrate (HMB)
A naturally occurring metabolite of the amino acid leucine is beta-hydroxy-beta-methylbutyrate (HMB). HMB is thought to function by boosting muscle protein synthesis and reducing muscle protein breakdown.HMB is frequently offered as a dietary supplement for people who lift weights and build muscle. There is, however, little scientific evidence to back up these uses.According to some research, HMB may benefit those who are new to weightlifting by boosting their strength and muscle mass. Other research, however, has not revealed any advantages of HMB supplementation in seasoned weightlifters.
