ALCAR
Acetyl-L-carnitine, also known as ALCAR, is an acetylated form of L-carnitine. It is naturally produced by the body, although it is often taken as a dietary supplement. ALCAR is believed to play a role in energy production by transporting fatty acids into the mitochondria where they can be burned up and used as fuel.
