Brain and Nerve Cell Function. Transports Fatty Acids. Boosts Cellular Energy. Vegetarian/Vegan. Acetyl L-Carnitine (ALC)is a modified amino acid that supports cellular energy production by assisting in the transport of fat into the mitochondria where it is oxidized and converted into ATP (cellular fuel). ALC is a highly bioavailable form of L-Carnitine that can cross the blood-brain barrier, where ithelps to manage oxidative damage, supports mitochondrial function and helps to maintain normal neurotransmitter activity. Clinical studies suggest that ALC helps to maintain optimal neurological health.
