Your body produces about 0.1mg of melatonin daily. Doses of 10-50mg are apparently used in cancer treatments. And a Dutch study suggested that 30mg of melatonin daily could act as a contraceptive, so be careful about how much you take...

Is a lethal overdose of melatonin possible?

Well researchers cannot seem to identify a 'lethal dosage' of melatonin, but nevertheless, melatonin will apparently build up in your body if you take regular high doses of it.

The consequences of taking regular high doses of melatonin are still unknown. But one study in Holland tested doses of 75mg of melatonin on 5000 women over a period of 5 years and concluded that it was not dangerous, even at these high levels.

Nevertheless, when it comes to taking any kind of supplements, it's always best to be cautious. Talk to your doctor before taking any melatonin supplements.
