Acetyl-L-Carnitine (acetyl carnitine) is a more bioavailable form of the amino acid L-Carnitine and is involved in many metabolic functions.
As an antioxidant, acetyl carnitine can protect neurons from damage caused by superoxide radicals.
Acetyl carnitine is involved in other aspects of neuronal metabolism and its molecular structure resembles the neurotransmitter acetylcholine. Also, acetyl carnitine supplementation supports energy utilization through fatty acid metabolism in the mitochondria.
