Checked against public sources on September 2, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

EPA + DHA dose is within one studied range. This lines up the amount on the label with the range used in the linked studies.

“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

“BRAIN, AND JOINT HEALTH - A single teaspoonful of Carlson Cod Liver Oil provides 1,100 mg of omega-3s, including EPA and DHA, which support heart,…”

The panel lists 870 mg EPA + DHA per serving (1 Teaspoon (5 mL)). One randomized dose-response trial used 300–1,800 mg/day; omega-3 studies vary widely. This is research context, not a recommendation or safety verdict.

Evidence →

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

“PURITY AND”

No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. 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.

Evidence and sources

Label #337525 “Kid's Norwegian Cod Liver Oil Natural Lemon Flavor” (Carlson), entered 2025-08-22, with the full Supplement Facts on file. Company on file: Distributor — Carlson Division of J.R. Carlson Laboratories, Inc., Lincolnshire, IL, USA.

Locked evidence record →Open the full source-linked finding
CheckedCan you trust the review pattern?

We can see -32 of this product’s 2,380 reviews — the count fell between January 26 and August 27, 2026. That is too small a slice to say anything about the wider pattern.

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

Evidence and sources

Written reviews fell from 2,412 to 2,380 between January 26 and August 27, 2026. The largest rise inside any single 30-day window was about 113, 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

EPA + DHA

870 mg per serving — within the 300–1800 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 500 mg of omega-3 (EPA + DHA) per serving. Studies we found used 300 mg–1.8 g a day, so this sits inside that range.

0studied 300 mg–1.8 g

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

The related page's review pool may differ from the observed listing. Because the page does not publish a matching UPC/GTIN, LookCloser does not attribute that review aggregate to this exact sellable unit.

Prices and stock are point-in-time observations. Related pages are never used as product evidence. No affiliate links; LookCloser earns nothing from these sellers.
