Who Benefits from HMB?

    Beta-Hydroxy Beta-Methylbutyrate, derived from the amino acid leucine, is a popular supplement with bodybuilders for building muscle mass and decreasing fat. Several studies showed that the supplement is safe and effective for increasing lean tissue and strength and preventing tissue breakdown after intense training. Other studies have not found any benefits. A review of literature by Alexis Ortiz from Texas Women’s University concluded that HMB benefits some people more than others. It works best in people without a history of strength training, athletes involved in high intensity periodized training, older adults and people suffering from degenerative diseases such as cancer and AIDS. HMB promotes muscle protein synthesis and cellular repair. (Strength and Conditioning Journal, 35 (8): 73-77,2013)
