Melatonin - Effects on the Body

Effects on the Body

Because research has not been able to prove or disprove the benefits of supplemental melatonin, it is difficult to pinpoint all of the effects it has on the body. If taken at the proper time, usually bedtime, melatonin has been shown to help regulate sleep. However, using too much melatonin or not using it according to directions could hinder instead of help the body's sleep/wake cycle.

Though found naturally in the human body, melatonin, if taken as a supplement, can have certain side effects. These include sleepiness, headache and dizziness, nausea, stomach cramps, irritability, and depression. Users claim it causes more intense dreams, even nightmares. Melatonin has also been found to prevent ovulationThe release of an egg from an ovary.. Some women have even used it to avoid getting pregnant. Overall, no serious side effects have been reported, and no long-term effects, negative or positive, have been proven.

The Fountain of Youth?

Some researchers believe that melatonin holds the key to a longer life. Walter Pierpaoli, William Regelson, and Carol Colman reported in their book The Melatonin Miracle: Nature's Age-Reversing, Disease-Fighting, Sex-Enhancing Hormone, that "melatonin is a potent age-reversing compound." They added that "we are confident that melatonin's primary benefit is in its ability to prevent disease by preventing the downward spiral that leads to illness." Their beliefs stem from research with mice, including studies that revealed mice that had improved health and longer lives as a result of taking melatonin. They also cited studies that showed older mice live longer when given pineal glands from younger mice and that the younger mice with the older pineal glands die at an earlier age. However, no studies on humans have been done that conclude that melatonin helps diminish the aging process.
