L-Carnitine L-Tartrate
[Product Introduction]
L-Carnitine (LC) is a vitamin-like substance derived from the amino acids lysine and methionine, requiring nutrients like vitamin C and iron for synthesis. It plays a crucial role in Food & Nutrition by acting as a coenzyme to transport long-chain fatty acids into the mitochondrial matrix for energy production through beta-oxidation. Typically, L-Carnitine appears as a white crystalline powder, highly water-soluble, and stable under acidic conditions. Besides facilitating fat metabolism, it regulates skeletal muscle protein balance by influencing protein synthesis and hydrolysis. Additionally, its antioxidant and anti-inflammatory properties help mitigate exercise-induced muscle damage. As a versatile Food Additive, L-Carnitine is widely used in sports nutrition and functional foods. Some production processes also utilize Plant Extract methods, catering to plant-based markets.
