Beta-Hydroxy-beta-Methylbutyrate (HMB), a metabolite of leucine, works against the breakdown of muscle proteins similarly to leucine but is much more effective. HMB also promotes muscle building, protects cell membranes, counteracts cortisol, which promotes muscle breakdown. HMB contributes to tissue regeneration and muscle building, regulates nitrogen levels in the body, protects and regenerates muscles, reduces body fat, and has muscle-building and endurance-promoting effects.
