Brain and Nerve Cell Function Transports Fatty Acids Boosts Cellular Energy A Dietary Supplement Vegetarian/Vegan Amino Acids Family Owned Since 1968 GMP Quality AssuredAcetyl-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 converted into ATP (cellular fuel). ALC is a highly bioavailable form of L-Carnitine that can cross the blood-brain barrier, where it helps 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.
