Questions people ask

Is 10 mg of melatonin too much?

Most labels here print 1–5 mg per serving, and studies on sleep timing used 0.5–3 mg; 10 mg products exist but are the top of the range. Start with the smallest serving the label allows and talk to your doctor if you need it nightly.

Melatonin or magnesium for sleep?

They do different things — melatonin is a timing signal, magnesium a mineral many people are low in. Our comparison page puts the two labels side by side.
