Beta-Hydroxy Beta-Methylbutyrate, more commonly known as HMB, is an active metabolite of the Branched Chain Amino Acid, Leucine. Leucine is an amino acid, one of the building blocks of protein.
Taking HMB, along with the amino acids arginine and glutamine, you may increase strength, improve body composition, and reduce muscle damage when used during resistance training or intense endurance exercises
HMB is a great addition to your post workout supplementation.
