Most research involving acetyl-L-carnitine has used 500 mg three times per day, though some research has used double this amount.1
Acetyl-L-carnitine is a molecule that occurs naturally in the brain, liver, and kidney. It is also available as a dietary supplement.
Acetyl-L-carnitine levels may decrease with advancing age. However, because it is not an essential nutrient, true deficiencies do not occur.
