Helps the body with aerobic exercise (running, skiing, biking, etc) to process fat stores into energy. I agree immediately before exercise. This improves endurance jog lasting 30 minutes or more. That is, the time of onset of fatigue is removed when there is no strength to move his legs. Accordingly, when the regular training and balanced diet reduced fat stores. It makes sense to take just before the intensity and duration of aerobic exercise. The drug works only with you. This L-carnitine in its action does not differ from similar products of other well-known manufacturers, which I've tried.
