Melatonin is a hormone that occurs naturally in the human brain and it is excreted from the pineal gland. This hormone regulates other hormones within our bodies and helps manage our internal clocks. Melatonin production is at its peak during the night when it is dark, and during the day when the sun is shining the production is much lower.
It can also help manage the female reproductive hormones, which helps control the timing and release of female reproductive hormones. Studies have also shown that when women take 3 mg of melatonin daily it can help determine when a women starts menstruation. Studies have also shown that the fertilization rate among women who took melatonin improved their chances to conceive by 20% compared to women that did not take the supplement.
When melatonin is taken at low doses over a short period of time, there are very few side effects. At higher doses, on the other hand, side effects from melatonin can occur. Headaches and nausea can occur when three milligrams a day or more of melatonin is taken. It can also cause the person taking melatonin to have next-day fatigue, irritability, and hormone fluctuations. These melatonin side effects also may include reduced blood flow, vivid dreams, nightmares, or possibly hypothermia.
Melatonin may aggravate symptoms in people who have auto-immune disorders or orthostatic intolerance. For people experiencing the latter condition, studies have found that melatonin reduces nerve activity. Melatonin side effects can include raised blood pressure for people who are taking medicines to control their blood pressure. Another side effect from melatonin is increased blood sugar in people who have diabetes and are taking certain kinds of medications. It has also been shown that this hormone can worsen the symptoms of depression and may increase a person’s risk of having a seizure.
Other melatonin side effects may include sleepwalking, confusion, and even abdominal discomfort. Daytime drowsiness and dizziness are also included in side effects from melatonin supplements. If you take melatonin, you should not take it for more than two months at a time, as taking it for longer periods of time because it may harm you. It has also been found that melatonin that has been extracted from animals may carry viral material or other contaminants. Synthetic melatonin is much safer and there is no risk involved in taking this version. Before buying melatonin supplements check the label and make sure it is made from artificial ingredients.
You should not operate heavy machinery or drive long distances after taking melatonin. Before you begin taking melatonin, you should consult your doctor, especially if you have any health conditions. Your doctor will make sure that you are healthy enough to take the supplement.
