The Melatonin Dosage for a Sleep Aid

Melatonin is a hormone made by your brain that helps regulate your body's internal clock 2. Your levels of melatonin increase at night and decrease during the day 2. Some people find that taking melatonin supplements helps them to sleep better, especially if they are suffering from jet lag 2. Different people respond to different dosages, so it may take some experimenting to find the dose that works best for you.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Insomnia

Although studies have used doses of anywhere from .1 mg to 75 mg per night, most people take doses between .3 mg and 5 mg per night. To minimize the risk of daytime side effects, start with a low dose taken about an hour before bedtime and increase your dose every three days until you find the dose that helps you. Most people respond well to doses between 1 mg and 3 mg. Quick-release forms of melatonin supplements may work best for people with insomnia 2.
