L-Carnitine has been around for decades for one main reason… IT WORKS. It taps into the body’s fat supply by supporting the transport of fatty acids to the muscles’ mitochondria where they can be burned off as energy. Muscle contains the highest concentration of Carnitine in the body, which is why it is important for athletes. Break down fat – Your body can use L-Carnitine to help break down fat stores and burn them for energy. No Stimulants – These fat store burning properties work without the use of stimulants so it can be combined with any other fat burning aid you may be using as part of your daily supplement regimen. L-CARNITINE XS 3000 contains 3,000 mg of pure L-Carnitine per serving with a total of 31 servings per bottle to last you the entire month.
