Natural Factors L-Carnosine - 500 mg - An antioxidant naturally found in skeletal muscle, brain tissue, and the heart. It protects cells against oxidative stress, promotes cellular rejuvenation, protects cognitive function and memory, and speeds muscle recovery after exercise. L-carnosine’s natural ability to both protect against and delay aging make it an ideal longevity and anti-aging nutrient. 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).
