We should have the ability to distinguish the "green safety, no side effects" declared by many businessmen. Although L-carnitine is good, L-carnitine is also suitable for people and taboos. Not all types of obese people can expect it. Let's learn about the taboos of L-carnitine.

1. Without exercise, the main function of L-carnitine in the body is to transport fat to mitochondria. Therefore, L-carnitine is not a direct product to lose weight. It is ineffective to eat L-carnitine alone without exercise. Exercise must be the first.

2. Take the wrong time. L-carnitine works from 1 hour to 6 hours after taking it. For people who have already used L-carnitine, only after taking L-carnitine for 1 hour and cooperating with moderate intensity aerobic training for 1 to 2 hours can they lose some weight.

3. Taboo long-term use, long-term use of L-carnitine will increase the risk of atherosclerosis, because L-carnitine is used by bacteria in the human intestinal tract, will produce trimethylamine oxide, this substance may lead to atherosclerosis, so taking L-carnitine should adopt the principle of discontinuity.

4. Taboo excessive supplementation has great side effects. When L-carnitine is used more than one gram a day, some people will nausea and vomit. Therefore, it must be clear that the dosage of L-carnitine should not be exceeded. At the same time, patients with kidney disease are forbidden to take L-carnitine.

In addition, menstrual women, patients with liver and kidney disease, patients with hypertension and heart disease, pregnant and lactating women, children and extremely weak people are not suitable for L-carnitine.
