Carnosine, featuring the characteristic imidazole-ring, is a dipeptide molecule, made up of the amino acids beta-alanine and histidine. It is highly concentrated in muscle and brain tissues. Carnosine and carnitine were discovered by Russian chemist Vladimir Gulevich.
Carnosine is used by mouth to prevent signs of aging and for preventing or treating complications of diabetes such as nerve damage, eye disorders (cataracts), and kidney problems. It is also used to improve muscle strength and exercise performance along with many other uses.
