L-Carnosine is a natural body product consisting of the amino acids beta-alanine and L-histidine chemically bound to each other. Nerve cells (neurons) and muscle cells (myocytes) contain high levels of Carnosine. Carnosine is NOT a drug, vitamin or mineral and it does not react with any drugs. You are born with high levels of Carnosine in your body but unfortunately it decreases with age. The good news is that you can now replace Carnosine naturally with a daily supplementation.
L-Carnosine is the most effective anti-carbonylation agent yet discovered. (Carbonylation is a pathological step in the age-related degradation of the body's proteins.) Carnosine helps to prevent skin collagen cross-linking which leads to loss of elasticity and wrinkles. L-Carnosine is a super antioxidant that quenches even the most destructive free radicals: the hydroxyl and peroxyl radicals, superoxide, and singlet oxygen. Carnosine helps to chelate ionic metals (flush toxins from the body).
It also acts as a regulator of zinc and copper concentrations in nerve cells, helping to prevent overstimulation by these neuroactive minerals. What is known about the biological role of Carnosine in the body substantiates all of the above and other studies have indicated further benefits.
L-Carnosine is classified as a dipeptide, which is a combination of two amino acids, in this case alanine and histidine. It naturally occurs in high concentrations in skeletal muscle tissue, and therefore may support muscle vitality. L-Carnosine is also an antioxidant that stabilizes cellular membranes, protecting them from damage by free radicals.* Because L-Carnosine is only found in vertebrates, it is especially important for persons who do not consume beef, pork or chicken.
