Zarbee's Kids Melatonin Sleep Supplement Liquid

Checked against public sources on August 9, 2026 · LookCloser does not sell or recommend supplements.

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.

Who’s behind it?🇺🇸Zarbee's, Inc.corporation · DELAWARE, USA
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
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.

Partly confirmed1

“guidance: Each melatonin 1 mg serving of our liquid melatonin works naturally to help promote peaceful sleep in kids ages 3+ years*; natural berry…”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

Claimed without support found1

“size: The serving size contains 1mg of clinically studied melatonin to help promote peaceful sleep in”

We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.

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…”

CheckedIs the label honest?

Every ingredient shows its amount · 3 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.

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

Melatonin

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

Linked ingredient research · label amount, not a recommendation
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.
