Carnosine is a protein building block that is naturally produced in the body. It is found in muscles, the heart, brain, and many other parts of the body.

Carnosine is important for many normal body functions. There's interest in using it to prevent aging because it seems to block certain chemicals that might play a role in the aging process. Carnosine levels in the body might also go down with age.

People use carnosine for aging, diabetes, autism, heart failure, depression, and many other conditions, but there is no good scientific evidence to support these uses.

Carnosine is also called L-carnosine. Don't confuse this with L-Carnitine. These are not the same.
