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 contribute to muscle performance and may have potential benefits for aging and cognitive function. Research suggests that carnosine may help reduce the effects of glycation, a process that can lead to cellular damage and aging. It is also being studied for its potential role in various health conditions, including diabetes and neurodegenerative diseases.
