Formulation Notes

Acetyl-L-Carnitine (ALC) is a naturally occurring nutrient in the body that is involved in the metabolism of fatty acids into the universal energy molecule ATP. ALC supports the biosynthesis of acetylcholine, a key neurotransmitter for brain and nerve cell functions which regulates activities of the vital organs, blood vessels, and communication between nerves and muscles. ALC also supports levels of glutathione, a significant antioxidant sustaining neurons and protecting cellular components from superoxide radicals. Helps metabolize fatty acid to generate cellular energy Helps support neurotransmitter for brain and nerve cell functions Helps support neurons and protect cellular components from superoxide radicals
