Melatonin contributes to reduce the time taken to fall asleep. Drasanvi’s Melatonin contains 1,9 mg of pure melatonin in each capsule. It is a supplement whose main active ingredient is melatonin. This substance is a hormone that is naturally secreted by the hypophysis gland and regulated by light. This hormone is connected to the biological clock – our waking and sleeping times.
