When is it better to eat L-carnitine? L-carnitine should be taken 1 hour before exercise, because L-carnitine takes effect 1 ~ 6 hours after taking it, and it has a very obvious fat-reducing effect after taking it with aerobic training. For those who exercise regularly, you can choose to take it half an hour before exercise, and those who don't exercise at ordinary times can choose to take it at meals, but it is still recommended to cooperate with exercise. It should be noted that L-carnitine should not be taken within half an hour before going to bed. Long-term use of L-carnitine is not recommended. It is generally recommended to take it for one month and then stop taking it for one week. The daily dose should not exceed 6 capsules. If you take it in large quantities for a long time, you may have side effects such as diarrhea.
It is also worth noting that when taking L-carnitine products, we must pay attention to drinking more water, because the metabolism of fat needs the participation of water. Don't take other amino acid products while taking L-carnitine, otherwise it may affect the absorption of L-carnitine. It is not recommended for people with renal insufficiency, liver or kidney diseases.
