Flavor
Strawberry
The fast-dissolve standard — strawberry tablets that melt under the tongue, no water needed, from the #1 melatonin brand.
Natrol owns the melatonin shelf for a reason: the fast-dissolve format absorbs starting in the mouth, works without water (travel, bedside), and doses can be split by breaking tablets. 5mg is above the evidence-backed 0.5-1mg sweet spot — start with half a tablet. 100% drug-free and vegetarian.

Frequently asked questions
Is 5mg too much melatonin?
For most adults the effective dose is 0.5-1mg — the fast-dissolve format makes halving easy, so start with half a tablet. Higher doses mostly add morning grogginess, not power.
Fast-dissolve vs regular tablets?
Dissolves start absorbing in the mouth, act a bit faster, and need no water — that's the whole practical difference. Great for flights.
Can I take it nightly?
Melatonin is best for TIMING problems (jet lag, shift work, schedule drift). Nightly long-term use builds behavioral reliance; most sleep doctors suggest short courses.
Natrol vs Nature Made?
Nature Made carries USP verification; Natrol wins on the dissolve format and flavor. Purity-first: Nature Made. Convenience-first: Natrol.
