The effect of Circadin (melatonin)
The active ingredient in Circadin is melatonin, a hormone that is also produced by the human body. If you have a normal biorhythm, your body does not make much melatonin because of the influence of (day)light. In the evening, when the light is less, the melatonin production starts. Melatonin is a hormone which makes you tired and fall asleep. You can use Circadin substitution is when your body’s own melatonin is not sufficient; Circadin works just like your own melatonin was doing.
