What is L-carnitine? L-carnitine, also known as L-carnitine or L-carnitine, is a nutrient similar to amino acids. In human body, lysine, methionine, niacin and other substances can synthesize a small amount of carnitine. Red meat and animal products are the main food sources of carnitine, but most people can only absorb 50 mg from their diet. In order to achieve ideal health, the daily diet should contain no less than 250-500 mg of carnitine. Sports people, people with high mental stress and other people lacking L-carnitine, such as the elderly, need extra supplements, especially athletes engaged in heavy exercise training.
The main physiological function of L-carnitine in human body is: as a carrier of fatty acid transport, medium and long-chain fatty acids are transported from the outer membrane of mitochondria to the inner membrane in the form of acetyl L-carnitine, and oxidized in the mitochondrial matrix to generate energy. This physiological function makes L-carnitine supplement have many important functions.
Is L-carnitine reliable for losing weight? L-carnitine is not a slimming drug, and it has no slimming effect. L-carnitine is added to some diet pills containing L-carnitine on the market now, but L-carnitine can play the role of fat porter in human body, promote fat burning and provide energy for the body. As for how much fat can be consumed, it does not depend on L-carnitine. If you want L-carnitine to burn fat, you must cooperate with exercise. ?
Under normal circumstances, the amount of exercise (energy consumption) is not large, and the fat consumption is not much. Just increasing L-carnitine will not increase the oxidation function of fat, so it will not help to lose weight.
L-carnitine can accelerate fat oxidation, reduce the concentration of triglycerides in blood and tissues, and has an important impact on energy metabolism in the body. L-carnitine can be used to prevent myocardial ischemia, alleviate the heart damage caused by myocardial infarction, prevent arrhythmia and reduce blood lipid.
The role of L-carnitine
1, lose weight, lose weight. ?
2. Reduce serum total cholesterol and triglyceride, increase serum high density lipoprotein, and prevent heart disease. ?
3. Help the body burn fat during exercise and improve energy, endurance and performance during exercise. ?
4. Promote pyruvate metabolism and energy supply, and reduce the accumulation of lactic acid in muscle cells.
5. Enhance the ability of myocardial cells to oxidize fat and reduce the burden on the heart during high-intensity exercise. ?
6. Enhance physical vitality and relieve fatigue.
7. Improve human immune function and liver function. ?
8. Prevent lipid peroxidation during exercise and protect muscle fibers from free radicals. ?
9, slow down the aging process of the human body. L-carnitine, as a multifunctional, safe and side-effect nutritional supplement, has attracted many people in the sports field, mainly used for reducing fat, enhancing endurance and resisting fatigue.
10, L-carnitine has side effects on the body, which can lead to liver and kidney damage and hyperhidrosis. In addition, L-carnitine contains drugs that excite the nervous system, which can also lead to insomnia.
