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 confirmed2

“Greenfield Nutritions Halal Fish Oil 1000mg, 300mg Halal Omega 3, Small Wild Peruvian Fish Oil Halal Vitamins, EPA 180 mg & DHA 120mg, Non-GMO,…”

The panel lists 300 mg EPA + DHA per serving (1 Softgel). 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 →
“QUALITY: All our Halal Vitamins and Fish Oil products are made in the USA by manufacturers that are GMP certified, and FDA registered; most of our…”

“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

“QUALITY: All our Halal Vitamins and Fish Oil products are made in the USA by manufacturers that are GMP certified, and FDA registered; most of our…”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →

We looked and found no public proof. That does not count against the product.

What is worth knowing.

Headlines first. Open evidence only when you want the source trail.

CheckedIs the label honest?

Every ingredient shows its amount · 9 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.

CheckedWho is behind it?

The barcode identity checks out · 852510005101.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

The brand's store lists this exact barcode as “Halal Fish Oil 1000mg Omega 3 - Halal Beef Gelatin” (variant: Default Title) — identity confirmed across retailer listings.

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

300 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 1 g 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.

Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $18.99; Brand website was highest at $29.00 — a $10.01 range at check time.

The observed listing and exact brand page repeat 1000 mg, 600 mg, 360 mg, 240 mg. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
