How Much Melatonin Should You Take? Finding Your Serving Size

Melatonin serving sizes commonly range from 0.5 mg to 5 mg. Sleep isn't one-size-fits-all, so the right amount depends on you — start low and adjust. A liquid makes this easy: a full 1 mL dropper of Restful You* provides 5 mg, and graduated marks let you fine-tune your serving instead of being stuck with fixed pill strengths.

A simple starting point

Many people start at the lower end — around 0.5–1 mg — and adjust upward only if needed. A gentle serving is often enough to support your natural sleep-wake cycle, especially once timing and wind-down habits are in place.*

Why a liquid makes serving flexible

With fixed strength pills, you're locked into whatever the tablet contains. With the Restful You* dropper you can dial your serving anywhere from about 0.5 mg to a full 5 mg, so travel nights and easy nights don't have to look the same.

When you might want more or less

• Disrupted rhythm (jet lag, shift change): some people prefer a fuller serving to help reset timing.*

• Easy nights or first-timers: a smaller serving is a sensible place to begin.*

If you're unsure what's right for you, check with a qualified healthcare professional.
