However, by slightly altering the chemical structure of this nutrient (adding the acetyl group), it can cross the blood-brain barrier and function to support both brain health and energy production. *. SUPPORT ENERGY PRODUCTION - Acetyl-L-Carnitine is the acetylated ester of L-carnitine and plays an important role in the transfer and utilization of long-chain fatty acids, which are used in the production of energy. Each capsule contains 800 mg of Acetyl L-Carnitine. *. NATURAL COMPONENT OF OUR BRAIN'S CHEMISTRY - Acetyl-L-Carnitine (ALC) is a natural component of our brain's chemistry and promotes the production of acetylcholine, the most abundant neurotransmitter in the brain. The body makes ALC in small amounts, but as we age, levels decline. Acetylcholine is involved in supporting memory, focus, and learning. It also serves to regulate activities of vital organs and blood vessels and communication between nerves and muscles. *.
