Contains the science-recommended daily allowance of 3 grams of HMB. ?-HMB (?-hydroxymethylbutyrate) is a metabolite derived from the metabolism of one of the three branched chain amino acids, Leucine. In muscle cells, HMB acts as a metabolic intermediary, amplifying the capacity for energy production, stimulating protein synthesis and reducing protein catabolism. In addition, HMB constitutes an intracellular cholesterol precursor molecule that improves the integrity of the cell membrane, reducing its disruption during exercise and helping to maximize the absorption of nutrients during and after training. The increase in intracellular levels of ?-HMB has been related to improvements in the processes of recovery, reconstruction and muscle growth.
