A major cause of aging is a reduction in the energy-producing components of the cell, resulting in reduced cellular metabolic activity, and the accumulation of cellular debris. L-carnitine helps maintain cellular energy metabolism by assisting in the transport of fatty acids from the cytosol into the mitochondria within the cell, where fats are oxidized to produce the cellular energy (adenosine triphosphate or ATP).
The acetylated form of L-carnitine (acetyl-L-carnitine) facilitates the release and synthesis of acetylcholine by donating its acetyl group to the production of acetylcholine, an important neurotransmitter. Acetyl-L-carnitine also enhances the release of dopamine from neurons and helps it bind to dopamine receptors.
Acetyl-L-carnitine is as effective as L-carnitine in carrying fatty acids across the membrane into the cell where they are burned as energy, but also promotes optimal brain health. With the discovery of acetyl-L-carnitine arginate, the benefits of acetyl-L-carnitine can now be greatly augmented.
