L-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 is naturally produced in the body by the enzyme carnosine synthetase. L-Carnosine supports healthy aging and cellular rejuvenation by its effects on two mechanisms: glycosylation and FREE RADICAL DAMAGE. Glycosylation is the oxidation of protiens 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.
