Why? Because L-carnitine is a naturally occurring compound in human cells, the human body can synthesize L-carnitine by itself, and food can also provide part of it. In cells, the basic function of L- carnitine is to transport fatty acids from mitochondria to the inner membrane of mitochondria. Because fatty acids can only be oxidized in mitochondria to release energy, fatty acids outside mitochondria cannot be oxidized into energy, so L- carnitine is just a carrier, just like a car transporting fat, and how much fat is consumed does not depend on L- carnitine.
If the amount of exercise is not large and the fat consumption is not much, just increasing L-carnitine will not increase the energy supply of fat oxidation, so it will not help to lose weight. Only when there is a lot of exercise, such as athletes or bodybuilders, the energy consumption per unit time is relatively high and the energy supply flow of fat oxidation is relatively large, so the synthesis of L-carnitine is relatively insufficient. At this time, taking extra L-carnitine is beneficial to the oxidation and consumption of more fat, so taking L-carnitine only when you have a lot of exercise is helpful to lose weight.
