Carnitine/L-Carnitine

Acetyl-l-carnitine (γ-trimethyl-β-acetylbutyrobetaine [ALC]) is the acetyl ester of carnitine. ALC is present throughout the central and peripheral nervous systems, plays an essential role in the oxidation of free fatty acids, and has displayed neuroprotective properties. Carnitine is available without a prescription as a dietary supplement, and is found in highest concentrations in red meat and dairy products.
