HMB, also known as β-hydroxy-β-methylbutyrate, is an active metabolite of the essential branched-chain amino acid leucine, which can promote protein synthesis and reduce its decomposition, thereby increasing human body strength, delaying muscle fatigue, and also helping to prevent muscle atrophy in the elderly. The concentration of HMB in human plasma is 1~4Lmol/L, and the concentration can be increased by 5~10 times after eating, and the half-life is about 2~4 hours, but whether it is injected or additionally ingested, about 30% of HMB will be absorbed by muscles, so HMB is also used as a new nutritional supplement to increase strength and increase muscle volume.
