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 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.
