L Carnitine vs. Acetyl L Carnitine: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 2, 2024
L-Carnitine aids in energy production by transporting fatty acids into mitochondria; Acetyl L-Carnitine, a form of L-Carnitine, also benefits brain function.

Key Differences

L-Carnitine is a naturally occurring amino acid derivative, essential for transporting long-chain fatty acids into mitochondria for energy production. Acetyl L-Carnitine, a form of L-Carnitine, has an added acetyl group, which enhances its ability to cross the blood-brain barrier.
