The dangers of melatonin

Written on March 31, 2025, by Pauline de Santarome

Melatonin is a hormone naturally produced by the pineal gland, also known as the epiphysis, located in the brain. Regulated by the light-dark cycle, its soporific action is its inhibitory effect on the biological clock. The secretion of this hormone is very low during the day and particularly high during the night.

Melatonin can be taken in various forms, including as a supplement. However, as with any supplement or medication, it is important to speak to a healthcare professional before considering taking melatonin.


Melatonin supplements are very effective in treating sleep disorders, synchronizing circadian rhythms, reducing the effects of jet lag, and treating light adaptation disorders. They improve the quality of your sleep and your mood in the long term.

Side effects of melatonin

 

Melatonin is much more than just a regulator of the biological clock. It also has other physiological properties that can modulate mood, strengthen the immune system, influence sexual behavior, and regulate body temperature. However, melatonin can also cause unwanted side effects.

 

According to a recent study by the French Agency for Food, Environmental and Occupational Health & Safety (ANSES), 90 cases of side effects have been reported after using dietary supplements containing melatonin. The most frequently reported symptoms are dizziness, nightmares, headaches, hormonal changes, nausea, and abdominal pain. These reactions demonstrate that melatonin-based products should be taken with caution and closely monitored by consumers.

Drug interactions

 

Melatonin may interact with the effectiveness of other medications, including antidepressants, anticoagulants such as aspirin and warfarin, birth control pills, and medications for high blood pressure.

These interactions may increase hypnotic effects such as: 

  1. The risk of drowsiness, 

  2. Memory and concentration problems, 

  3. Visual hallucinations, 

  4. Balance disorders, 

  5. Extrapyramidal syndromes, 

  6. Low blood pressure.

If you are already taking medication, consult a doctor before taking melatonin.

Effects on mental health 

 

Melatonin is an effective and natural treatment for many health problems. It is safe and has very few side effects when used appropriately. However, melatonin can be habit-forming, particularly in terms of mental health, and it is therefore important to follow the recommended dosage to avoid any adverse effects.

 

According tothe ANSM, more than 200 cases of adverse effects linked to the consumption of melatonin-based products or medications were reported between 1985 and 2016. Among these, mental disorders were the most frequently reported, particularly depression and anxiety.

 

Some people also report increased irritability and feelings of nervousness and agitation. In older adults, melatonin may cause confusion and memory problems.

 

It is important to speak with a healthcare professional before taking melatonin or any other supplement if you have a history of mental health issues. Healthcare professionals will be able to help you determine whether melatonin is a safe and appropriate choice for you, based on your medical history and current treatments.

Potential risks associated with long-term excessive consumption of melatonin 

 

Melatonin is a hormone naturally secreted by the brain. Some people do not produce enough of it for various biological reasons. In this case, melatonin can be taken as a dietary supplement to relieve sleep disorders, fall asleep more easily, and avoid waking up during the night.

 

Unlike sleeping pills or psychotropic substances, melatonin-based dietary supplements do not cause physical dependence but can lead to psychological dependence, making their use necessary to maintain regular sleep patterns.

 

Don't worry, melatonin is safe when taken at the recommended dosage. It is best to take one tablet about 30 minutes before going to bed with a large glass of water. If you are experiencing jet lag, take one tablet before going to bed on the first day of your trip and for a few days after arriving at your destination.
