This is educational information, not medical advice. Melatonin can interact with blood thinners, immunosuppressants, and some diabetes medications; most doctors recommend avoiding it during pregnancy and breastfeeding; and it may worsen mood in people with mood disorders. If you take prescription medication, are pregnant or breastfeeding, or have a mood disorder, talk to a doctor before trying any supplement on this page. See our full melatonin guide for dosing and safety details.
The short version
At 300 micrograms (0.3mg) with a 6-hour timed-release design, this is the lowest-dosed, most research-aligned product in this entire roundup — below even the 0.5-1mg range our own guide describes as typically effective, and structured to release gradually rather than all at once.
What it actually is
Per the manufacturer’s listing:
- 300mcg (0.3mg) melatonin — a genuinely low dose, no cutting or splitting needed
- 6-hour timed-release tablet, not a fast-dissolve gummy — designed to release gradually through the night
- Gluten-free, non-GMO, vegetarian, 100 tablets
Why timed-release matters for staying asleep
A fast-dissolve gummy delivers its full dose quickly and clears your system over a few hours — useful for falling asleep, less useful if you wake up in the middle of the night. A timed-release tablet is built to release more gradually, which may help with the specific problem covered in our sleep maintenance insomnia guide — falling asleep fine but waking up partway through the night.
Who it’s a good fit for
Anyone who wants to start at the low end of the research-recommended range without splitting gummies, or who specifically struggles with staying asleep rather than falling asleep.
Where it’s probably not the right pick
It has the smallest review base in this roundup (under 2,000, versus 27,000+ for the other melatonin picks) — less data behind the rating, though the rating itself is solid. It’s also a tablet, not a gummy, if flavor/format matters to you.
Bottom line
The most conservative, dose-appropriate melatonin product in this comparison — worth considering first if you haven’t tried melatonin before, or specifically if staying asleep (not falling asleep) is your issue.
