What type of forms is carnitine used?

Carnitine, a compound made from amino acids in the body, can be used in different forms. The most common form is L-carnitine, which is used to treat carnitine deficiencies and may help heart problems. Scientists have examined the use of acetyl-L-carnitine for age-related memory and fatigue problems, although its effectiveness is still being questioned. Propionyl-L-carnitine has been studied for circulation issues, heart failure and erectile dysfunction.

Carnitine supplements are usually taken in pill form, although it can also be given through an intravenous (IV) line by a health-care professional. Speak with your doctor before taking carnitine.
