Research on this acetylated derivative of L-carnitine has centered largely on its role in maintaining brain and nerve function during aging.* The acetyl group can serve as a metabolic source of acetylcholine, a brain neurotransmitter, while the L-carnitine component carries fatty acids into mitochondria of nerve, heart, and muscle cells for use in energy production.* Other actions benefit membrane stability, production of nerve growth factor, and cerebral blood flow.* Provided in its stable, hydrochloride form.
