Supports Muscle VitalityFree Radical ScavengerSupports Cell IntegrityL-Carnosine (beta-alanyl-L-histidine) is a dipeptide, consisting of alanine and histidine. It is naturally found in high concentrations in muscles and nerve tissues and its levels are known to decrease with age. L-Carnosine protects cell and tissue structures during the aging process through its free-radical neutralizing and membrane-stabilizing functions.
