Carnitine is a non-essential amino acid. Carnitine is acetylated into Acetyl-L-Carnitine (ALCAR) in the brain, liver, and kidneys.
In living cells, it is required for the transport of fatty acids from the cytosol into the mitochondria during the breakdown of lipids (fats) for the generation of metabolic energy.
Regular supplements of L-carnitine, however, contribute to energy metabolism and improved neurotransmitter function in the brain in elderly patients.*
