L-Carnosine is actually a combination of two amino acids, in this case alanine and histidine. This naturally-occuring substance has multiple functions in this body, the most remarkable of which is its ability to rejuvenate cells close to the end of their life-cycle (a state called senescence), revitalizing their appearance and increasing their span. L-Carosine is also a potent antioxidant that is able to protect proteins from several different forms of protein modification, including oxidation and carbonylation (the breakdown of protein cell membranes, leading to early cell death). Research shows that destructive changes to proteins over a normal lifespan significantly contribute to aging and the signs of aging, such as wrinkle skin and decreased cognitive function. Which means Carosine may Enhance to maintain youthful vigor and appearance.
