🧪 Formulation Notes

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 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.
