Applications

L-Carnitine is a natural, vitamin-like nutrient responsible for promoting the β-oxidation process of long- chain fatty acids. In other words, it helps the body convert fatty acids into energy. L-Carnitine is often used in medicine and health food, sports drinks, infant nutrition and animal nutrition
