L-carnitine is a kind of amino acid that promotes the conversion of fat into energy. When used correctly, it generally has no toxic and side effects on the human body. Its main functions and effects include reducing weight, enhancing endurance and anti fatigue, and maintaining the physical function of infants.

　　1. Weight loss: as an essential coenzyme in fat metabolism, L-carnitine can promote the metabolism of human fat and accelerate the combustion of fat, so as to play an auxiliary role in weight loss. At the same time, after a long period of vigorous exercise, the transport capacity of L-carnitine in the body will also be enhanced, so as to further accelerate the combustion and oxidation of its own fat and achieve the ideal fat burning and slimming effect;

　　2. Enhance endurance and anti fatigue: L-carnitine can improve the oxidation function of human body by changing the activity of respiratory enzymes in mitochondria to a certain extent, so as to help enhance the endurance of human muscles. At the same time, the use of L-carnitine after exercise can help delay the occurrence of muscle fatigue symptoms and eliminate excessive lactic acid in the body, so as to improve exercise ability;

　　3. Requirements for maintaining the physical function of infants: L-carnitine, as an important substance to promote the conversion of fat into energy, is an essential nutrient for infants and can maintain the physical development of infants. L-carnitine has been added to many infant milk powder on the market;

　　4. Other functions and effects: when the human body's high-density cholesterol increases, L-carnitine can help reduce the levels of triglycerides and cholesterol in the blood and minimize its damage. L-carnitine is also an energy substance for sperm maturation, which can help improve sperm motility and quality to a certain extent.

　　Because L-carnitine mostly exists in red meat, you can eat more lean meat in daily life, including red meat such as beef and pork. However, because it is not a drug, if you want to achieve a certain effect, you need to cooperate with other methods, such as weight loss, you still need to cooperate with diet control and appropriate exercise.
