How to Take It

Best taken in the evening

Time-release melatonin spreads the dose across the night. The licensed prolonged-release version is taken 1–2 hours before bedtime, with or after food. Vitamin B6 is easier on the stomach taken with food.

With food

On the label

Take 1 tablet 20 minutes before bedtime.

General guidance based on the ingredients, not a substitute for the label or your doctor.
