Is Melatonin Safe to Take Every Night?
For most adults, low-dose melatonin is safe for nightly use, but higher doses and long-term misuse are common reasons people experience side effects or feel worse over time. More is not better when it comes to melatonin.
Low dose vs High dose melatonin
Melatonin is a hormone, not a sedative. Your brain naturally releases it in very small amounts to signal nighttime — far less than what many supplements contain.
- Low doses (often under 3 mg) help support natural sleep timing
- High doses can overwhelm the system and cause grogginess or vivid dreams
- Taking more does not make melatonin work better or faster
Does melatonin cause tolerance?
Melatonin does not work like traditional sleep drugs, but taking excessive doses night after night can blunt your body’s sensitivity to its natural rhythm.
When people say melatonin “stopped working,” the issue is often dose or timing — not true dependence.
Timing matters more than dosage
Melatonin works best when taken in alignment with your circadian rhythm. Taking it too late or too close to bedtime can shift your internal clock instead of supporting it.
This is why a universal “30 minutes before bed” rule doesn’t work for everyone. 30 minutes to 3 hours has been the range concluded by modern studies, it's good to experiment with timings to find what suits you best.
Common misconceptions about melatonin
- It does not knock you out like a sleeping pill
- Higher doses are not more effective
- Feeling groggy often means the dose is too high
- Melatonin supports sleep timing, not sleep depth
Quick FAQs
