L-carnitine, commonly known as fat incendiary bomb, is an essential coenzyme in the process of fat metabolism and can promote fatty acids to enter mitochondria for oxidative decomposition. It's like a forklift scooping up fat and burning it in an oil burner. If fat does not enter mitochondria, no matter how you exercise or diet, you can't consume it. L-carnitine only acts as a "porter" from fat to mitochondria. In order to achieve the ideal degree of fat burning, the body needs an ideal balance of carnitine content. However, the amount of carnitine synthesized by human body and the amount ingested from food are far from meeting the needs. Therefore, with the increase of age or insufficient consumption due to excessive energy intake, fat accumulation is becoming inevitable. It is precisely because of the low level of L-carnitine in the body that only a few people can maintain a certain level of L-carnitine. Therefore, properly supplementing L-carnitine and burning fat in time will make you healthy, slim and charming.
