Acetyl-L-Carnitine

Acetyl-L-carnitine is a compound that is found naturally in the human body. This compound is also available in dietary supplements and is claimed to have several medicinal uses.

How Does It Work?

Acetyl-L-carnitine is essential for proper functioning of mitochondria, the "energy factories" of human cells. For most people, the body can make plenty of this compound on its own, making supplementation unnecessary. However, for some individuals (such as premature infants or people with certain genetic defects), supplementation with some form of carnitine (such as acetyl-L-carnitine) is necessary. In critical situations, the use of the prescription product levocarnitine (Carnitor®) is usually preferred.
 
It is not entirely clear exactly how this compound works for the various conditions for which it is used, although different mechanisms have been suggested by researchers.
 

Is Acetyl-L-Carnitine Effective?

Preliminary research suggests that this supplement might be effective for a number of different uses, although more research is necessary to confirm these early findings (see Does Acetyl-L-Carnitine Work? for more information).
