L-Carnitine is known for its benefits but it can also produce some side effects you should be aware of. L-Carnitine is naturally produced in human body and its main role is to turn fats into energy. This process takes place in cell mitochondria.

Body uses this energy to function normally. It highly contributes to well-being of liver and heart. It improves circulation and reduces amounts of fat which is very important for health in general.

Because of this fat-reducing quality, it is commonly used in weight loss diets. Athletes also use it because it turns fat into energy which allows them to exercise more efficiently. As a supplement, it should be taken with food, three times a day. It is available in tablets, capsules and powder.

Is L Carnitine Safe?

Side effects of L-Carnitine are not serious and in most of the cases, they are easy to treat. Some of them include problems with sleep (because of extra energy produced in the body); headaches and restlessness. There can be some rather unpleasant side effects like vomiting, nausea and diarrhea. There were few cases of severe side effects like heartbeat changes (fast heartbeat) and blood pressure increase. Fever was also reported in some consumers. People who have problems with thyroid gland and those on dialysis are strongly advised not to take L-Carnitine in any form. This refers to other supplements, too.

Vomiting can be caused by other factors, like bad digestion, certain types of foods and other supplements. It is not very severe, but it certainly means that something is just not right. Therefore, if you start vomiting, you should rest your body for a while and change your diet temporarily to see what happens. Nausea usually occurs before vomiting, so these two are treated in the same way. Diarrhea can be quite unpleasant. It rarely gets severe, but if you experience this side effect only once, it means that your body is trying to tell you something. Stop using supplements for a while and see what happens. If you feel restless, you should stop using L-Carnitine or reduce the dose. It would be better to talk to your doctor about this. Perhaps you can use some other supplement instead of L-Carnitine.

Women who use L-Carnitine usually have no problems at all. However, some women have reported problems with menstrual cycle. We cannot know if these problems are related to L-Carnitine, but menstrual cycle changes are possible in women who exercise hard and use certain supplements. It this happens to you, visit your doctor and see if there is anything wrong.

As you can see, side effects are mild and rare but they are possible. So if you want to use L-Carnitine in any form and for any reason, you should consult your physician first. If you are taking any medications or suffer from any health problem, it is strongly recommended to ask for a professional opinion. Also, it is very important to follow the instructions written on the pack. That way you will get the best results.
