Acetyl-l-carnitine arginate is a patented form of carnitine that stimulates the growth of neurites in the brain. Studies show that acetyl-l-carnitine arginate stimulates the growth of new neurites by an astounding 19.5%, which is almost four times better than acetyl-l-carnitine.

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.83 Acetyl-l-carnitine also enhances the release of dopamine from neurons and helps it bind to dopamine receptors.84,85 Numerous human and animal studies validate the multiple beneficial mechanisms that acetyl-l-carnitine exerts in the brain.*

Acetyl-l-carnitine is more effective than L-carnitine in carrying fatty acids across the membrane into the cell where they are burned as energy.86-89 Since 1995, Life Extension members have been supplementing with acetyl-l-carnitine and deriving the many benefits this form of carnitine has shown in published scientific studies. With the discovery of acetyl-l-carnitine arginate, the benefits of acetyl-l-carnitine can now be greatly augmented.*

Acetyl-l-carnitine-arginate is a patented form of acetyl-l-carnitine. This amino acid boosts mitochondrial energy production through its ability to facilitate fatty acid transport across the membrane into the cell where they are burned as energy.96-99 Since 1995, Life Extension members have been supplementing with acetyl-l-carnitine and deriving the many benefits this form of carnitine has shown in published scientific studies. With the discovery of acetyl-l-carnitine- arginate, the benefits of acetyl-l-carnitine can be greatly augmented.

For some people, L-carnitine, especially acetyl-l-carnitine, may have a stimulating effect. Therefore, it may be unwise to take it in the evening.
