L-Carnitine plays a critical metabolic role in stimulating weight loss as it helps transport fats to the mitochondria where they are burned for energy. Clinical research has shown L-Carnitine supports athletic performance and endurance. Through a greater reliance on fat for energy, the body reduces depletion of muscle glycogen. This combined with the reduction of lactic acid accumulation in muscles can extend exercise capacity before fatigue. L-Carnitine L-Tartrate capsules can be recommended pre-workout.
