Is melatonin harmful?
by Laura VDS on Jun 20, 2023
Melatonin is a hormone naturally produced in the brain that plays an important role in your sleep-wake cycle . As soon as it gets dark, melatonin production increases, signaling our bodies that it is time to sleep . Towards morning, production decreases again, causing us to wake up.
Not everything depends on your body's internal production. There are also external factors that can affect your natural melatonin production. Exposure to bright light, stress, caffeine consumption and irregular sleep patterns can suppress melatonin production.
Use of melatonin as a supplement
Melatonin is often used in supplements to help with sleep problems. It is available over the counter at pharmacies and drugstores , which makes it seem like a safe and harmless substance.
Effectiveness of melatonin
Studies show that users fall asleep an average of 10 to 20 minutes faster when taking melatonin. Melatonin is especially effective for sleep disorders related to a disrupted biological clock.
In addition, the effectiveness of melatonin varies from person to person. Some people react strongly to a small dose, while others hardly notice any effect . This is because the metabolism of melatonin varies from person to person . It actually depends a bit on your genetics and lifestyle.
How much melatonin can you take?
In Belgium, melatonin is available without a prescription up to a dose of 3 mg . For doses higher than 3 mg, a doctor's prescription is required . This law was introduced because higher doses can have a negative effect on your biological clock and increase the chance of side effects .
In the Netherlands , higher doses are available without a prescription . This is why many Dutch people use melatonin as a sleeping pill. Experts warn against these high doses, because your sleep quality can deteriorate instead of improving.
In general, it is recommended to start with a low dose, for example 0.3 mg to 1 mg , and only increase if this does not help sufficiently. Doses that are too high will cause unwanted side effects without providing any benefits.

Side effects of too much melatonin
The use of melatonin is not without risks. Possible side effects include:
- Disruption of the sleep rhythm : Incorrect use can lead to a disrupted biological clock, which can result in problems with falling asleep and staying asleep.
- Daytime sleepiness and drowsiness : Taking melatonin may cause sleepiness and drowsiness during the day.
- Headache and dizziness : Some users experience headaches and dizziness after taking melatonin.
- Gastrointestinal complaints : Side effects such as nausea, abdominal pain and constipation may occur.
- Hormonal disruptions : Long-term use of high doses can affect hormone balance, especially in young people and women.
- Psychological effects : Some users report mood swings, nightmares, and worsening of anxiety symptoms.
