NOW Acetyl-L-Carnitine is a highly bioavailable form of the amino acid L-carnitine, specifically formulated to support optimal neurological health and cellular energy production. This compound facilitates the transport of fatty acids into the cell’s mitochondria, where they are converted into ATP (cellular fuel), a vital process for high-demand tissues like the brain. Acetyl-L-Carnitine can cross the blood-brain barrier, offering support for cognitive functions such as memory, mental clarity, and overall healthy aging. This product provides 500 mg of Acetyl-L-Carnitine per vegetarian capsule in a 50-count bottle. It is designed for adults to take 1–2 capsules once or twice daily as needed.
