"-Carnosine is a dipeptide composed of the covalently bonded amino acids alanine and histidine and is found in the brain, heart, skin, muscles, kidneys and stomach. L-Carnosine supports healthy aging and cellular rejuvenation by its effects on two mechanisms: glycosylation and FREE RADICAL DAMAGE. Glycosylation is the oxidation of proteins by glucose resulting in cross-linking of proteins and which is implicated in loss of cell function, genome integrity and accelerated aging. L-Carnosine also protects the aging process of the brain by retarding lipid peroxidation and stabalizing cell membranes."
