Does the marketing hold up?

FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Trouble on record?Brand history — not this product

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed1

“KIDS NIGHTTIME GUMMIES: These gentle, drug free, safe, and effective chews promote sleep* for those nights when your little one has trouble…”

Ingredient evidence exists; on dose: label claims 1 mg/serving — within the range commonly used in research (sleep trials commonly use 0.5–5 mg; higher doses are not shown to work better and gummy products have repeatedly been found to differ from their labels).

FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Evidence and sources

This recall is not about the product on this page. Zarbee's Naturals Inc. recalled a different product on September 21, 2015. FDA has since closed that case. The recalled item was “Baby Omega 3 Dietary supplement (in liquid form), 15 ml and 14 ml in glass bottle with dropper…”

Needs explanationIs the label honest?

The label says 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 2,000 mg — 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…

The label shows a visible consistency problem

Check this exact wording or duplicate row on the package before relying on the printed amount.

Evidence and sources

The label visibly shows: “Total Carbohydrate appears more than once”; “Total Sugars appears more than once”; “Includes Added Sugars appears more than once”; “Melatonin appears more than once”. This is a specific printing or product-image inconsistency worth checking on the…

Listing claim matches the Supplement Facts panel

The label promise and the Supplement Facts amount agree.

Evidence and sources

The listing claims 1 mg; the photo-read Supplement Facts panel shows Melatonin at 1 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

CheckedIs the label honest?

Every ingredient shows its amount · 13 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

Evidence and sources

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Public contextWill you get what you pay for?

Reaching a studied dose costs about $7/month

Comparing cost at a research-relevant amount shows how quickly the package is used and what the routine actually costs.

Evidence and sources

At 1.0 serving(s) a day to reach the low end of the studied range (0.5–5 mg), this product runs roughly $7 per month. A price observation, not a recommendation.

CheckedCan you trust the review pattern?

Reviews rose from 142 to 329 between August 2, 2025 and August 27, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 142 to 329 between August 2, 2025 and August 27, 2026. The largest rise inside any single 30-day window was about 35, so the count moved in steps rather than in one burst.

Research behind the findings

Dose and research context

The label amount is shown beside the range used in the linked ingredient studies.

Dose vs research

1 mg per serving — within the 0.5–5 mg/day used in the linked studies.

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 1 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.
