1, what is L-carnitine?
L-carnitine is a key substance in the process of fat metabolism, which can promote fatty acids to enter mitochondria for oxidative decomposition. Red meat is the main source of L-carnitine, and the human body can also synthesize it itself, because L-carnitine has no toxic and side effects on the human body, and it has been widely used in weight loss products and foods.
2. Is L-carnitine useful?
It's useless if you don't cooperate with exercise. L-carnitine plays the role of a porter in the process of losing weight. Its main function is to transport fat to mitochondria. It is a carrier enzyme. If you want to use L-carnitine to lose weight, you must cooperate with proper exercise and reasonable diet. Eating L-carnitine alone will not have a good weight loss effect.
3. When can L-carnitine be eaten?
The human body will produce L-carnitine itself. If the energy consumption is high and the fat consumption is low, blindly increasing L-carnitine will not increase the oxidation function of fat, which will not help to lose weight. However, when the exercise is high and the energy consumption is high and the synthesis of L-carnitine is relatively insufficient, taking L-carnitine and expanding the carrier for transporting fatty acids will help the body consume more fat, which will have the effect of losing weight.
4. Tips
1, L-carnitine can be taken half an hour before and after meals. It should be noted that it is best not to take it within one hour before going to bed. It has certain excitability, so as to avoid the excessive energy of L-carnitine affecting sleep quality.
2. At present, it is considered that the safety range is 1000 mg/day ~ 5000 mg/day. Do not take a large amount of amino acids at the same time, because amino acids may affect the absorption of L-carnitine.
3. L-carnitine works after taking 1 hour ~ 6 hours. Therefore, aerobic training is needed after taking L-carnitine 1 hour, and the effect of reducing fat will be the most obvious.
5. Side effects
Side effects of L-carnitine 1: Diarrhea L-carnitine is produced in the liver and kidney of human body and stored in the heart, brain and muscle. L-carnitine needs to be balanced by the kidney and stored in the kidney. People with weak liver and kidney function often have adverse reactions and even pathological changes when taking L-carnitine. If you take levorotatory too much, diarrhea may occur.
Side effects of L-carnitine: affecting sleep L-carnitine burns fat, provides energy, and also makes people excited, which has the same anti-fatigue effect as coffee. Therefore, taking L-carnitine may often lead to insomnia and affect the quality of sleep. revolve
Side effects of L- carnitine: malnutrition L-carnitine itself can be used as a nutritional additive, but in the process of taking L-carnitine, it often requires less energy and reduces appetite. L-carnitine needs to be combined with carbohydrates to strengthen physical fitness and enhance the metabolic ability of body fat. If you take L-carnitine for a long time, high consumption and low intake will cause malnutrition and decrease your body function. Side effects of L-carnitine 4: D- carnitine damages muscles L-carnitine itself is a safe and non-toxic substance, but the purity of L-carnitine used for weight loss is often questionable. L-carnitine in industrial production often contains a certain amount of D- carnitine. D- carnitine not only has no weight loss effect, but also does harm to muscles, causing muscle weakness and muscle atrophy.
L-carnitine has a high safety factor among all weight-loss products. However, the side effects and harm of L-carnitine can not be ignored. If you choose L-carnitine to lose weight, you must pay attention to avoid its side effects as much as possible. Methods to avoid the side effects of L-carnitine Before using L-carnitine, the applicable population of L-carnitine should be cleared first, and people with weak liver and kidney function should use it with caution. During the period of taking L-carnitine, we should strengthen supplementary nutrition and have a comprehensive and moderate diet. Drink plenty of water to help detoxify and avoid taking L-carnitine before going to bed. When buying L- carnitine, L-carnitine with purity above 99% should be selected, and the quality of some seemingly cheap L-carnitine is often not guaranteed.
