MaryRuth's Organic Liquid Zinc Drops for Kids

Checked against public sources on July 26, 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.

Is the dose real?Panel read — dose not verified3 ingredients listed; no advertised amount we could confirm against them

Who’s behind it?🇺🇸MRO MaryRuth, LLClimited liability company · Delaware, USA
Is it the real thing?Barcode matches outside 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.

Marketing claims, checked

The checks, one by one

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

Partly confirmed2

“MaryRuth's Organic Liquid Zinc Drops for Kids, Immune Support, Vegan,”

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

Evidence →
“of Common Allergens: Kids Liquid Ionic Zinc by MaryRuth's is USDA Organic, Non-GMO, Vegan, Made in a GMP”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Evidence →

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

?Couldn’t verify independently1

“tested for 200+ toxins & contaminants, as well as verified for product label”

No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →

We looked and found no public proof. That does not count against the 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. MARY RUTH ORGANICS recalled a different product on October 28, 2021. FDA has since closed that case. The recalled item was “MaryRuth's Organic Infants Liquid Probiotic; Unflavored, a Dietary Supplement. 1 fl. oz.…”

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.

Locked evidence record →Open the full source-linked finding
What remains open 3
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.
  • No dated review-history series is on file yet.

These are evidence gaps, not strikes against the product.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

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 6 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits below that range.

0studied 8 mg–40 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
