What is melatonin used for?

Melatonin is commonly used to help with insomnia symptoms, jet lag, and circadian rhythm sleep-wake disorders. It can be especially helpful when sleep timing is shifted later than desired.

What is a typical melatonin dose for sleep?

Many people use 0.5–5 mg taken shortly before bedtime. Lower doses may be sufficient for circadian rhythm shifting, while higher doses are sometimes used for short-term sleep support.

How long does melatonin take to work?

Melatonin is often taken 30–60 minutes before bedtime, though timing can vary by goal. For jet lag or circadian rhythm adjustment, taking it at the target local bedtime is commonly used.

What are common melatonin side effects?

Possible side effects include next-day drowsiness, vivid dreams, headache, or dizziness. Effects can be more noticeable with higher doses or when taken too late at night.

Who should be cautious with melatonin?

People who are pregnant or breastfeeding, have epilepsy, autoimmune conditions, or take sedatives or blood thinners should consult a clinician before use. It can also affect alertness, so avoid driving if you feel drowsy.
