DL-Carnitine is widely used in dietary supplements and pharmaceuticals due to its role in energy metabolism. It helps transport fatty acids into mitochondria, where they are oxidized to produce energy, making it popular in weight management and sports nutrition products. It is also used in the treatment of certain metabolic disorders where the body cannot properly process fats for energy. In addition, DL-Carnitine supports heart health and has been studied for its potential benefits in improving exercise performance, reducing muscle fatigue, and enhancing recovery after physical activity. It is also found in some animal feed formulations to improve growth performance and meat quality.
