Lean Mass Synthesis

Meaning

Lean Mass Synthesis is the physiological process of generating new muscle, bone, and connective tissue, which is primarily driven by anabolic hormones and adequate substrate availability. This process involves the integration of amino acids into muscle protein, resulting in a net positive protein balance that increases muscle cross-sectional area and strength. Maximizing lean mass synthesis is a cornerstone of healthy aging, metabolic function, and physical vitality.
