Can You Overdose on Melatonin?

Reading Time: 3 minutes

Have you ever found yourself unable to fall asleep at night? Or tossing and turning for hours on end? 

Well, you’re not alone. In fact, according to the Centers for Disease Control and Prevention, one-third of U.S. adults report that they usually get less than the recommended amount of sleep. 

With such a high percentage, it’s no wonder why people are turning to melatonin supplements for help. However, there’s a question that often arises among consumers: Can you overdose on melatonin supplements?

How to Tell If Your Body is Making Enough Melatonin

Before we dive into whether or not you can overdose on melatonin supplements, let’s take a look at why people turn to them in the first place. 

Melatonin is a hormone produced by the pineal gland in the brain and is responsible for regulating our sleep-wake cycle. 

However, there are many factors that can disrupt the production of melatonin. These include everything from stress to certain medications. 

This is where supplements come into play. They can help bridge the gap between what our bodies are producing and what we need to get a good night’s rest.

Choosing the Right Melatonin Dosage 

Determining the right dosage comes down to several factors. These include age, weight, current medications, and health conditions. 

For example, individuals with liver disease may not be able to metabolize melatonin as effectively and may need a lower dosage. 

One thing is for sure: do your research and compare supplements before purchasing. Not all supplements are created equal, so choose a melatonin supplement that only contains necessary, quality ingredients to support your best sleep. There are also other supplements you can take to support the efficacy of melatonin tablets. 

It’s important to speak with a healthcare provider to determine the right dosage for you.

It’s important to know how much melatonin to take to avoid any potential risks. The standard dosage guidelines for adults is between 0.5-5 mg depending on individual needs. 

However, note that just because a higher dosage is available does not mean it’s safe or necessary. Higher doses can disrupt our natural sleep-wake cycle and lead to side effects.

Dosage Recommendations for Children

For children, the recommended dosage varies based on age and weight. In general, the recommended dosage for children ranges from 1 mg to 5 mg depending on their age and weight. 

It’s important to speak with a healthcare provider to determine the right dosage for your child.

Signs and Symptoms of Melatonin Overdose

So now, the important question: Can you overdose on melatonin supplements? The short answer is yes. 

While it is a naturally occurring hormone in our bodies, too much of it can lead to potential risks. Signs and symptoms of an overdose include nausea, dizziness, headaches, and disrupted sleep. 

However, it’s important to differentiate between side effects and actual overdose symptoms.

Side effects of melatonin supplements are common and can include drowsiness, headaches, and nausea. If these symptoms persist or worsen, you must speak with your healthcare provider. 

Actual overdose symptoms, however, are more severe and may include hallucinations, seizures, and respiratory distress. It’s important to seek medical attention immediately if you experience any of these symptoms.


Melatonin supplements can be a helpful tool for individuals struggling with sleep issues. However, it’s important to take the necessary precautions to avoid any potential risks. 

Always speak with a healthcare provider to determine the right dosage for you and never exceed the recommended amount. If you experience any potential overdose symptoms, seek medical attention immediately. Sweet dreams!
