Melatonin is one of the most popular sleep supplements in the world — but most people are taking the wrong dose.
Here’s what actually works, and the best options you can buy on Amazon right now.
What Is Melatonin and How Does It Work?
Melatonin is a hormone your brain produces naturally when it gets dark. It signals to your body that it’s time to sleep — it doesn’t knock you out like a sleeping pill, it just nudges your internal clock.
Supplements work best for:
- Jet lag
- Shift work
- Delayed sleep phase (night owls who can’t fall asleep early)
- Occasional insomnia
The Biggest Melatonin Mistake: Too Much
Most melatonin pills sold in the US are 5mg or 10mg. Research shows that 0.5mg to 3mg is all most adults need. Higher doses don’t work better — they can actually make you groggy the next day.
Start low. You can always increase if needed.
