Acetyl-L-Carnitine is the ester form of L-Carnitine; a naturally occurring amino acid metabolized from Lysine and Methionine and used extensively by the brain and nervous system. There is a significant amount of research on L-Carnitine's role in cardiac and skeletal muscle function and in its role in fat metabolism/loss.
N-Acetyl- L-Carnitine's research has focused mainly on its role in brain and nervous system function with regard to the aging process. The older we get, the more likely we are to suffer from cognitive/memory loss. Many nutrients have been studied for their potential in promoting brain health in older adults. N-Acetyl-L-Carnitine is one of those nutrients. N-Acetyl-L-Carnitine is involved in preventing age-related effects on the brain by protecting neurons from oxidative damage.
