What is Carnosine Carnosine is a small molecule composed of the amino acids, histidine and alanine. It is found in relatively high concentrations in several body tissuesmost notably in skeletal muscle, heart muscle, and brain.The exact biological role of carnosine is not completely understood, but numerous animal studies have demonstrated that it possesses strong and specific antioxidant properties. Carnosine has been suggested to be the water-soluble counterpart to vitamin E in protecting cell membranes from oxidative damage. Other suggested roles for carnosine include actions as a neurotransmitter chemical messenger in the nervous system, modulator of enzyme activities, and chelator of heavy metals i.e., a substance that binds heavy metals, possibly reducing their toxicity. What does it DO Researchers are finding that it's possible to block the increase of hydrogen ions, thus stabilizing pH levels and prolonging muscular activity. This is done by buffers or compounds in muscles that
