L-Carnitine
PH-LCAR-001
Specifications
Description
L-Carnitine is a naturally occurring amino acid derivative essential for fatty acid transport into mitochondria for energy production. This quaternary ammonium compound plays a critical role in cellular metabolism.
Mechanism of Action
L-Carnitine shuttles long-chain fatty acids across the inner mitochondrial membrane for beta-oxidation, enhancing energy production from lipids. L-Carnitine is one of the key nutrients for proper mitochondrial function and plays a major part in protecting cellular membranes, preventing fatty acid accumulation, and modulating ketogenesis (Virmani & Cirulli, 2022). Significant increases in mitochondrial function were observed in human neuronal cells exposed to L-carnitine (Ferreira & McKenna, 2013).
