HMB PRO features beta-hydroxy-beta-methylbutyrate (HMB), a natural metabolite of leucine that supports increased protein synthesis and decreased protein degradation. Vitamin D, which supports skeletal muscle health and function, complements HMB to render this formula an optimal choice for supporting muscle health.

HMB
Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the essential amino acid leucine, naturally present in human muscle cells, and it has been reported to have anabolic effects on protein muscle metabolism.[1,2] Several mechanisms of action have been proposed to explain the action of HMB on muscle health. Among them are that HMB attenuates training-induced proteolysis via downregulation of proteolytic pathways, and it acts as a signaling molecule for the stimulation of protein synthesis.[2-4]

Studies conducted mostly in athletes have suggested that HMB supplementation may exert beneficial effects on muscle mass and function, most notably when combined with resistance-type exercise training.
