Carnosine is highly concentrated in important tissues like those of the brain, the heart, and the muscles. It functions as a broad-spectrum antioxidant and supports the healthy functioning of enzyme systems. Many scientists suspect that carnosine plays a role in supporting longevity in some of our most vital organs. Swanson Ultra L-Carnosine delivers Right Age® Carnosine for healthy longevity.
