Carnosine is a naturally occurring dipeptide composed of two amino acids, beta-alanine and histidine. It is primarily found in muscle and brain tissues, where it plays a role in buffering acidity and protecting cells from oxidative stress. Carnosine is thought to support muscle function and may have potential benefits for aging and cognitive health. Research suggests that carnosine may help improve exercise performance and reduce fatigue. Additionally, it has been studied for its potential anti-aging properties, as it may help combat the effects of glycation, a process that can damage proteins and contribute to age-related diseases.
