Energy for cells and brain - acetyl-L-carnitine Acetyl-L-carnitine is considered an important building block for energy production and fat utilization as well as for the neurotransmitter acetylcholine. Unlike conventional L-Carnitine, which can be produced by the body itself, Acetyl-L-Carnitine has an additional acetyl group added. This extra acetyl group allows L-carnitine to cross the blood-brain barrier, the natural barrier between the bloodstream and the central nervous system. The acetyl content in acetyl-L-carnitine leads to a higher bioavailability and it can be absorbed more easily. In addition, acetyl-L-carnitine enables the formation of the important neurotransmitter acetylcholine, an indispensable messenger substance for numerous cognitive processes, which is required for the transmission of stimuli and information in the brain.
