Does the marketing hold up?
The label says 3.2 g of melatonin in 4 gummies — but not what those 4 gummies weigh. That weight is the one number that would let anyone check the amount on the front. We did not weigh it ourselves, so this is an open question, not a problem we found.

Evidence and sources
A serving is 4 gummies, and the panel lists 3,200 mg — 3.2 g — of melatonin in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of…

Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 3 mg; the photo-read Supplement Facts panel shows Melatonin at 3 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 3 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits inside that range.
0studied 0.5 mg–5 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

Does the brand page tell the same story?
Brand page 4.20/5 · retailer 4.5/5inspect
The exact brand page is lower by 0.30 points. The brand page publishes 1,232; the retailer surface shows 27,648. Different systems can collect different review pools, so this is a signal to inspect, not proof that reviews were manipulated.
The brand page did not expose a complete star-by-star breakdown in the captured structured data, so LookCloser cannot test whether lower-star reviews were omitted. Source: exact barcode-bound brand product page · retailer surface · counts do not prove authenticity.
