Acetyl-L-carnitine (ALCAR) is a form of the amino acid L-carnitine that can cross the blood-brain barrier. ALCAR is thought to enhance cognitive health by increasing the availability of acetylcholine, a neurotransmitter that plays a key role in memory and learning. It also acts as an antioxidant, which may help protect the brain from damage caused by harmful molecules called free radicals. Additionally, ALCAR has been shown to increase blood flow to the brain and improve the function of mitochondria, the energy-producing structures in cells, which may also enhance cognitive health.
