L-carnitine, also known as L-carnitine or carnitine, is an ingredient of food and is considered as a vitamin nutrient. It is an amino acid derivative, and its main function is to transport long-chain fatty acids through mitochondrial inner membrane to mitochondrial matrix for oxidation and energy supply. L-carnitine is also involved in the transportation of some branched-chain amino acid metabolites, which is beneficial to the normal metabolism of some amino acids and plays a role in reducing fat. Simply put, L-carnitine is like a "porter", which can move larger fat cells into the "burning furnace" of mitochondria. Reducing fat with its participation will get twice the result with half the effort.

L-carnitine has no toxic side effects on human body, is suitable for people to reduce fat with aerobic exercise, and has obvious effect, which is favored by the majority of fitness enthusiasts, especially female weight-loss sports enthusiasts. In fact, the body's own muscle tissue can secrete L-carnitine, but in order to achieve the ideal weight loss effect or maintain a good figure, it is necessary to reasonably adjust the balance of L-carnitine in the body. With the modern people's diet getting better and better and exercising less and less, it is often not enough for most people to rely on L-carnitine secreted by themselves, so a certain amount of exogenous L-carnitine can be properly ingested to supplement the deficiency of the body's own secretion.

Although L-carnitine has many benefits, people who use exogenous L-carnitine should know that L-carnitine is not a slimming drug, its main function is to transport fat, which is different from losing weight. If you want to lose weight with L-carnitine, the key is to cooperate with proper exercise and control your diet. As for the intake of L-carnitine, it should be controlled at about 250 ~ 500mg, and taking L-carnitine 200 ~ 500mg every day is enough to meet the needs of the body. On the contrary, if you take too much exogenous L-carnitine, it will make people feel sick and even vomit, which is often ineffective and harmful to the body.
