Acetyl-L-Carnitine is an established and well-researched dietary supplement. It is synthesized to furnish the body with a more bioavailable form of L-Carnitine. L-Carnitine is a derivative of the amino acid lysine and is naturally made by the body in the kidneys and liver. It is then transported to other tissues in the body such as the heart brain lungs and more. L-Carnitine is involved in cellular metabolism so supplementing with Acetyl-L-Carnitine can help increase energy production at the cellular level in the mitochondria. Mitochondrion (plural mitochondria) are basically the “power plants” of all cells. L-Carnitine’s name was derived from carnis (Latin for meat) since it was first isolated from meat in 1905.
