Carnosine is a small peptide that contains two amino acids, beta-alanine and histidine. It is found in relatively high concentrations in several body tissues, most notably in skeletal muscles, heart muscles, and the brain.
Carnosine nutrient supplements have been very popular among body-builders and athletes mainly for improving muscular fatigue. Based on hundreds of studies, carnosine in now being considered one of the most important supplements for longevity based on its properties. The exact biological role of carnosine is not completely understood, but studies indicate that it possesses strong and specific antioxidant properties, protects against radiation damage, improves heart function, and promotes the recovery from injuries. Additional, suggested benefits of carnosine include its role 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 to the body).
