Our verdict
Natrol Fast Dissolve is an inexpensive, transparent and pleasant way to take melatonin, and buyers largely report that it helps them fall asleep. Our reservation is the dose: 5 mg is more than most adults need, so we would start with Natrol's 1 mg or 3 mg tablets and only move up if a lower dose does nothing. Skip it if you avoid wheat or soy.
Best for
- Occasional sleeplessness or jet lag
- People who dislike swallowing pills
- Budget-conscious buyers
Skip it if
- Anyone avoiding wheat, gluten or soy
- Pregnant or breastfeeding people without medical advice
- Children unless a pediatrician recommends it

Our review
Natrol's Fast Dissolve tablets are among the most familiar melatonin products in the US: a small strawberry-flavored tablet that melts on the tongue, so there is no pill to swallow and no water needed. The 5 mg strength is the most-reviewed version on Amazon, and the same tablet is sold in 1 mg, 3 mg and 10 mg strengths.
The formula is simple and fully disclosed. Each tablet delivers 5 mg of melatonin in a base of xylitol, dextrose, cellulose gum and soy polysaccharides, with natural flavor and beet root color. At the brand's list price for 150 tablets it works out to roughly $0.11 per tablet, which is hard to beat.
Our main reservation is dose. Johns Hopkins sleep specialists describe melatonin as a hormone that eases you into quiet wakefulness rather than a knockout sedative, and they advise 1 to 3 mg taken about two hours before bed. At 5 mg, many people take more than they need, and more is not reliably better. Natrol's own 1 mg and 3 mg tablets are the more sensible starting point for most adults, and the 5 mg tablet can be split.
Buyer feedback is strongly positive: buyers consistently describe falling asleep faster and praise the taste and how quickly the tablet dissolves, while headaches are the side effect mentioned most often. iHerb's label listing states the tablets contain wheat and soy, which matters for anyone with celiac disease or a soy allergy. Natrol says its products are made under FDA cGMPs in NPA GMP-certified facilities, batch-tested for potency and heavy metals and checked by independent labs, but the line carries no USP or NSF certification.
What’s inside

Pros & cons
What we like
- About $0.11 per tablet at the brand's list price for 150 count
- Single-ingredient formula with no proprietary blend
- Dissolves in the mouth without water; buyers consistently praise the strawberry taste
- The same tablet comes in 1 mg and 3 mg, making it easy to step down to lower, evidence-aligned doses
- Made under cGMPs with batch testing for potency, microbes and heavy metals
Watch-outs
- 5 mg is above the 1-3 mg range sleep experts commonly suggest; headaches are the side effect buyers mention most
- Label lists wheat and soy, so it is unsuitable for celiac disease or soy allergy
- No USP, NSF or other named third-party certification, and no batch certificates of analysis on the product page
- Sweetened with xylitol, which is toxic to dogs, so store it out of pets' reach
Questions buyers ask
Is 5 mg of melatonin too much?
For many adults, probably. Johns Hopkins sleep specialists suggest 1 to 3 mg taken about two hours before bed, and higher doses are not reliably more effective. Buyers of the 5 mg tablets most often mention headaches as a side effect. Natrol sells the same tablet in 1 mg and 3 mg strengths, or you can split a 5 mg tablet.
Is Natrol Fast Dissolve gluten-free?
Do not treat it as gluten-free. iHerb's label listing for the 5 mg strawberry tablets states that it contains wheat and soy, and the base includes soy polysaccharides, dextrin and modified food starch. If you have celiac disease, a wheat allergy or a soy allergy, choose a melatonin with a certified gluten-free, allergen-free label.
Can I take it every night?
Natrol labels it for occasional, short-term use. The NIH's National Center for Complementary and Integrative Health says short-term use appears safe for most adults but long-term safety is unclear. If you need help sleeping most nights for weeks, talk to a clinician, especially if you take blood thinners, have epilepsy, or are pregnant or breastfeeding.
