Mechanism Comparison

Melatonin

Marketing claims: "Natural sleep aid," "10mg for deep sleep." Reality: More is NOT better with melatonin. 10mg is 10-30x physiological levels and can cause next-day grogginess, vivid dreams, and hormonal disruption with long-term use. Melatonin helps you fall asleep faster (~7 min), not sleep longer or deeper. It is best for jet lag and shift work, not chronic insomnia.

Magnesium

Marketing claims: "Natural calm," "Better sleep guaranteed." Reality: Magnesium helps sleep primarily in deficient individuals. If you are not deficient, effects are modest. Magnesium oxide (the cheapest form) has poor absorption (~4%) — glycinate, citrate, and threonate absorb much better (20-30%).
