Acetyl L-carnitine

Acetyl L-Carnitine (ALC) is a metabolite that occurs naturally in the brain, liver, and kidney, and is a dietary supplement that can be found in many animal products. It is also produced during high-intensity exercise, and Acetyl L-Carnitine's role in the synthesis of acetylcholine is important for the central nervous system. Though Acetyl L-Carnitine is not considered an essential nutrient, the body's production of this acetyl ester version of L-Carnitine can decrease with age, making it a great supplement to use in your fitness protocol.
