Everbuild Nutrition's HMB is a high-quality dietary supplement that contains the active metabolite of the essential amino acid leucine, known as β-hydroxy β-methylbutyrate (HMB). All the HMB present in the human body comes from dietary sources of leucine, with approximately 5% of dietary leucine being converted to HMB.

HMB helps reduce the breakdown of muscle proteins and mediates some of its effects.
