Signs of a Melatonin Overdose: What You Need to Know
What is a Melatonin Overdose?
While melatonin is considered generally safe, taking too much can lead to an overdose. There isn't a specific dose that is considered toxic, but excessive intake can disrupt your sleep and waking patterns, as well as cause other adverse health effects.
Common Signs of a Melatonin Overdose

- Daytime Drowsiness**: One of the most common signs of a melatonin overdose is excessive sleepiness during the day. If you find yourself feeling tired or groggy during the day, it could be a sign that you've taken too much melatonin.
- Headaches**: Some people may experience headaches or migraines after taking too much melatonin. This is usually due to the changes in blood vessels and the body's response to excess melatonin.
- Dizziness**: Melatonin can cause dizziness or lightheadedness, especially when taken in large doses. If you feel like you're going to pass out or experience extreme dizziness, seek medical attention.
- Upset Stomach**: Taking too much melatonin can cause stomach problems like nausea, vomiting, or diarrhea. If your symptoms persist, seek medical help.
- Joint Pain**: Some individuals may experience joint pain or stiffness after taking melatonin. This is usually due to the hormone's effect on the nervous system and joints.
- Abdominal Pain**: Excessive melatonin intake can cause abdominal cramps, bloating, or discomfort. If you experience severe abdominal pain, seek medical attention
- Night Terrors**: Melatonin can cause night terrors, also known as sleep terrors, in some individuals. If you experience extreme anxiety or terror during the night, it may be a sign of an overdose.
