1. Product Description
L-Carnitine is a quaternary ammonium compound naturally synthesized in the human body from lysine and methionine. It plays a crucial role in the transport of long-chain fatty acids into the mitochondria for β-oxidation and energy production. L-Carnitine is widely used in dietary supplements, sports nutrition, infant formula, and clinical nutrition products.
