As we age we need to protect the brain against neurodegeneration, as well as loss of cognitive function and memory. Carnosine has also been shown to rejuvenate connective tissue cells which can assist wound healing and the effects of aging of the skin. Carnosine is a naturally occurring molecule composed of two amino acids, histidine and alanine. Do not confuse it with carnitine.
Carnosine is found in higher concentrations of meat and fish so vegans may become deficient. The body can manufacture sufficient quantities but as we age this ability diminishes. By the time we are 70, carnosine levels have been decreased in the body by 63%. Carnosine has been shown to improve muscle function and recovery from muscle fatigue. It also protects against degeneration of the brain and loss of cognitive function associated with aging. Carnosine can improve mental function and behavior in children with autism and ADD and it can also heal peptic ulcers when combined with zinc.
