Versatile antioxidant support for cellular health and longevity | Versatile antioxidant support for cellular health and longevity L-Carnosine (beta-alanyL-L-histidine) occurs naturally in the body capsules by Pure Encapsulations muscle and nervous tissues and is formed by the amino acids alanine and histidine. Levels of this dipeptide can decline with age. It is a water-soluble antioxidant and promotes cell health and cell longevity. In vitro, L-carnosine maintains healthy advanced glycation end-product, or AGE, activity. These end-products are formed when aldehydes (such as aldose and ketose sugars) and lipid peroxidation by-products bind to proteins. L-Carnosine plays a role in maintaining DNA integrity. L-Carnosine may also support superoxide dismutase activity. In addition, L-carnosine may help to maintain healthy peptide metabolism in the brain and its membrane stabilizing properties support cellular health in the cardiovascular system. The concentration of L-carnosine in muscle may prove to be an important factor in high-intensity exercise performance based on a recent human study. L-Carnosine provides unique protective mechanisms in the body to maintain healthy protein and cellular function in various tissues.
