The branched-chain amino acid (BCAA) metabolite B-hydroxy B-methylbutyrate monohydrate (HMB) has been shown to support the body's ability to minimize protein (i.e., muscle) breakdown and damage to muscle cells, which can occur after intense resistance exercise.1 By reducing muscle tissue breakdown, HMB may tip the scales of protein turnover in favor of new muscle growth. EAS was the first company to bring HMB to the market. Since then, it has been written up in numerous health and fitness magazines, hundreds of newspapers, and it's been featured on dozens of TV news programs as an exciting, breakthrough supplement that might allow people to get better results faster from the time they spend exercising.
