Extra-Strength carnosine is multi-faceted anti-aging supplement. We use only the highest quality, top grade carnosine from European sources. As a naturally occurring combination of amino acids alanine and histidine (a dipeptide), carnosine is exceptional and distinctive in its ability to extend longevity benefits throughout the body. There is also a direct correlation between the life-span of a species of animal and the concentrations of carnosine in their muscle tissue. Carnsoine has been shown to provide the following functions: - Super antioxidant with superior protection of chromosomes against oxidative damage. - Protein anti-aging, safeguarding the protein-based infrastructure of the body against degradation. Proteins in the body define the structures of the body, and are necessary in performing the everyday functional activities. An 80 year old person looks different from a 20 year old, both on the inside and outside, due significantly to the aging of protein in the body. - Enhances heart contraction. Increases the contractibility of of cardiac muscle cells. (Roberts PR, Zaloga GP, Biochemistry (Mosc). 2000).
