If you’ve tried melatonin before, you probably wonder how much is enough. Too little might not help, and too much can leave you groggy. The good news is you can fine‑tune the dose based on a few simple factors. This guide walks you through the most common dosage ranges, when to take melatonin, and how to adjust it safely.
Most over‑the‑counter melatonin products start at 0.5 mg and go up to 10 mg per tablet. For adults, a typical starting dose is 1–3 mg taken 30–60 minutes before bedtime. If that doesn’t work after a few nights, you can bump it up to 5 mg. Doses above 5 mg rarely provide extra benefits and can increase the chance of morning drowsiness.
Kids and teenagers should use much lower amounts. A safe range for children aged 5–12 is 0.5–1 mg, and for teens 1–3 mg. Always check with a pediatrician before giving melatonin to a child, especially if they take other medications.
Start low and go slow. Begin with the smallest dose your supplement offers, note how you feel, and increase only if you still have trouble falling asleep. Keep a simple sleep diary: record the dose, time you take it, and how long it takes you to fall asleep. This data helps you find the sweet spot without guessing.
If you’re sensitive to hormones or take blood‑thinners, talk to your doctor before raising the dose. Some people notice vivid dreams or a “hangover” feeling at higher levels. In those cases, dropping back to 1–2 mg often solves the problem.
Weight and age also matter. Heavier individuals sometimes need a slightly higher dose, while older adults may respond well to just 0.5 mg. Adjustments should be small—add 0.5 mg increments and see how you react.
Timing is another key factor. Melatonin works best when taken about an hour before you plan to sleep. Taking it too early can shift your internal clock and make you feel sleepy earlier than intended. If you travel across time zones, adjust the timing gradually to match the new bedtime.
Finally, avoid alcohol and caffeine close to bedtime. Both can interfere with melatonin’s effectiveness and make it harder to gauge the right dose.
Remember, melatonin is a hormone, not a sedative. It signals to your body that it’s time to wind down, but it won’t force you to sleep if you’re lying awake with bright lights or loud noise. Pair the right dose with a calm, dim environment for the best results.
By starting low, tracking your response, and tweaking slowly, you can find a melatonin dosage that helps you fall asleep naturally without unwanted side effects. Give it a try and see how a small change can make a big difference in your nightly routine.
