1) L-Carnitine Fumarate enhance exercise endurance,L-Carnitine Fumarate improve athletic performance:Since L-Carnitine Fumarate can promote the oxidation of fatty acids across the mitochondrial membrane for energy, so when exercise can promote the body burn fat to provide energy, while L-Carnitine Fumarate can also promote the use of branched-chain amino acid oxidation, mitochondrial respiration may change enzyme activity, which can improve the ability of the body's aerobic oxidation for energy.

2) L-Carnitine Fumarate accelerating recovery from fatigue:L-Carnitine Fumarate can promote the intracellular pyruvate dehydrogenase activity, thereby promoting oxidation of glucose utilization, it is conducive to delay fatigue occurs during exercise. Produce too much lactic acid during exercise will increase the acidity of the blood and tissue fluid, reduce the formation of ATP, leading to fatigue, L-Carnitine Fumarate can remove excess lactic acid, improve exercise capacity, promote the recovery of sports fatigue. Ammonia is a product of protein degradation, but also the identification of exercise-induced fatigue, even if a lower ammonia content will have greater toxicity. The study found a protective effect of anti-L-carnitine ammonia toxicity can promote the urea cycle, degradation of ammonia urea, thereby releasing toxic ammonia.

3) L-Carnitine Fumarate Slowing aging:Energy is the largest anti-aging power, enough energy cells will be filled with vitality. In the human aging process, weakening cellular energy is one of the reasons for accelerated aging, appropriate supplement L-Carnitine Fumarate can delay the aging process.In addition, enough energy for cells play a protective role in senescent cells when the body energy supply,L-Carnitine Fumarate not only be abl to provide enough energy, but also to maintain a strong immune system, thus avoiding the invasion of some diseases.
