Acetyl L-Carnitine is a form of L-carnitine, only acetylated. It is a very popular dietary supplement derived from amino acids, methionine and lysine. L-carnitine helps fatty acids to cross the membrane of the mitochondria and become available for usage. ALCAR, which is an alternate name for acetyl L-carnitine, is currently under research for possible treatment of Parkinson’s disease and cerebral ischemia. Neuroprotective benefits have been already attributed to ALCAR, but also assistance in cases of Peyronie’s disease, strokes and in treatment of depression. In food it is very much present in Beef and other red meats, in smaller quantities in mushrooms and carrots. Scientific studies have verified that regular supplements of L-carnitine improve the energy metabolism and can promote the neurotransmitter functions in brains of elderly people.
