Melatonin is a hormone produced naturally in the body by the pineal gland, a small gland in the brain. It plays a crucial role in regulating sleep-wake cycles, also known as the body's circadian rhythm. Melatonin levels typically rise in the evening as it gets darker, signaling to the body that it's time to sleep. Conversely, levels decrease in the morning with exposure to light, helping to wake you up.

Is it Okay to Take Melatonin Every Night?

Melatonin is often used as a supplement to help regulate sleep patterns, especially in cases where natural melatonin production might be disrupted due to factors like shift work, jet lag, or certain health conditions. But a lot of people ask if melatonin is safe to take every night. In this blog, we will try to answer that question.

What Is the Safe Dosage?

The FDA (Food and Drug Administration) does not regulate melatonin as a drug. Many Scientific studies show that doses of melatonin vary widely from 0.1mg-10mg. It takes an approximate time of 1-2 hours for melatonin to work after consuming the supplement. However, if one is consuming melatonin for the first time it is advisable to consume lower doses.

What Happens if You Take Melatonin Every Night?

According to the National Center for Complementary and Integrative Health (NCCIH), short period use of melatonin supplements appears to be safe to use for most adults and children.

Several factors determine the suitability of taking melatonin daily, including the type of sleep issue, age, and overall health. For instance, individuals dealing with jet lag might use melatonin daily for a limited period, typically up to five days (1).

It is often said that too much of something can lead to side effects, however, there are mild side effects of consuming excess melatonin i.e., headache, dizziness, and excessive drowsiness. Melatonin, unlike many sleep aids, is safe and one is unlikely to become dependent.

Is it safe to take more than one dose during the night?

Many people find it difficult to fall asleep even after consuming a melatonin supplement. Taking more than one dose is unlikely to cause any harm. However, it may cause certain side effects. Melatonin also interacts with certain medications like blood thinners, diabetes medications and antidepressants, keep this in mind if you decide to take an extra dose of melatonin supplement.


Melatonin supplements are useful in regulating sleep-wake cycle, reducing jet lag and insomnia. Melatonin supplements are safe to use every night and the side effects are also mild. But if you are on certain medication consult with a healthcare professional before you start taking melatonin supplements.
