L-carnosine, also known as beta-alanyl-L-histidine, is a naturally occurring dipeptide composed of the amino acids beta-alanine and histidine. It is found in high concentrations in various tissues, including the brain, muscles, and heart. L-carnosine plays several important roles in the body.
- Antioxidant properties: L-carnosine is a potent antioxidant, meaning it helps neutralize harmful free radicals and reduce oxidative stress. Free radicals are unstable molecules that can damage cells and contribute to various diseases and the aging process.
- Anti-aging effects: Due to its antioxidant properties, L-carnosine is believed to have anti-aging effects. It helps protect cells from oxidative damage, which can lead to premature aging. Additionally, L-carnosine has been shown to inhibit the formation of advanced glycation end products (AGEs), which are associated with age-related diseases.
- Brain health: L-carnosine is found in high concentrations in the brain and is involved in various neurological processes. It has been studied for its potential benefits in promoting cognitive function, improving memory, and protecting against neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
- Muscle performance and recovery: L-carnosine has been shown to enhance muscle performance and delay muscle fatigue during intense exercise. It helps regulate muscle pH levels and buffers the build-up of lactic acid, which can contribute to muscle fatigue. L-carnosine may also support muscle recovery and reduce exercise-induced muscle damage.
- Other potential benefits: L-carnosine has been investigated for its potential role in supporting cardiovascular health, immune function, and eye health. However, further research is needed to fully understand these potential benefits.
