Formulation Notes

How it works: Acetyl-L-Carnitine (ALC) is a naturally occurring component of fat metabolism and cellular energy production. ALC readily crosses the blood-brain barrier and promotes healthy nerve cell function by maintaining normal mitochondrial bioenergetics, stabilizing cell membranes, and contributing to the production of acetylcholine, an important neurotransmitter that plays a role in learning and memory. ALC also supports the brain's natural free radical neutralizing defenses.
