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 glutathione, a significant antioxidant sustaining neurons and protecting cellular components from superoxide radicals.
