Carnosine

Definition

Carnosine is a naturally occurring dipeptide made up of the amino acids beta-alanine and histidine, found primarily in muscle tissues and the brain. It is believed to have various beneficial effects in the body, especially in regards to exercise performance.

Scientific / Technical Definition

Carnosine (beta-alanyl-L-histidine) is a dipeptide composed of beta-alanine and L-histidine, notable for its presence and concentration in muscle tissues and the central nervous system. It plays a role in buffering acid in muscles during intense exercise, possessing antioxidant properties, and has potential neuroprotective and anti-aging effects.

Benefits

• Improves muscle endurance and reduces fatigue during high-intensity exercise by buffering lactic acid.
• Acts as an antioxidant, helping to reduce oxidative stress.
• May have neuroprotective effects, potentially supporting cognitive health.
• Could have anti-aging properties due to its ability to combat glycation and free radical damage.

Examples

• Chicken
• Beef
• Fish
• Supplements containing carnosine or beta-alanine

Additional Information

• Effects: Carnosine helps in delaying muscle fatigue, enhancing muscle performance, and protecting against oxidative stress.
