L Carnosine (beta-alanyl-L-histidine) is a dipeptide of the amino acids beta-alanine and histidine. It is highly concentrated in muscle and brain tissues. L-carnosine, sometimes called simply carnosine, is a combination of two amino acids, alanine and histidine. So it is known scientifically as beta-alanyl-L-histidine. L-Carnosine acts as an anti-oxidant, a substance that neutralizes free radicals. The specific uses of l-carnosine include support for the skin, joints and digestive system.
