Carnosine is naturally found in “excitable” tissues, such as muscle and nerve tissue, and reaches high concentrations in skeletal muscle. It functions in these tissues to maintain the proper pH and electrical charge. It also protects brain and muscle cells from oxidative damage.
Carnosine possesses additional benefits including neutralizing toxic heavy metals, promoting wound healing, and promoting healthy aging and cellular rejuvenation. In muscles, carnosine stimulates microcirculation, neutralizes the extensive formation of lactic acid during high intensity exercise, and promotes recovery from exercise. These effects accelerate the working capacity of muscle exhausted by preceding exercise. This explains carnosine’s popularity among bodybuilders and athletes for improving muscle function and recovery from muscle fatigue.
Carnosine is also very important for brain health as it has been shown to protect against neurodegeneration as well as loss of cognitive function and memory. Carnosine levels in the body decline with age. By the time a person is 70 years old, carnosine levels have decreased by 63%.
Carnosine has been shown to rejuvenate connective tissue cells, which may explain its beneficial effect on wound healing as well as why it’s used to fight the effects of aging on the skin (wrinkles and loss of elasticity). Because of its many beneficial effects, carnosine is becoming well-known as a longevity and anti-aging nutrient.
