How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
Panel, decoded
The 26 mg iron (as fermented iron bisglycinate) claim matches the panel
MARKETING26 mg — per-serving claim
PANELIron (as fermented iron bisglycinate) 26 mg — same amountOrganic beetroot 125 mg
matches panelWe did the comparison: the listing claims 26 mg of iron (as fermented iron bisglycinate), and the listing-image panel shows 26 mg iron (as fermented iron bisglycinate) 1 tablet. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin C (as ascorbic acid) | 15 mg | — | |
| Folate (as folic acid) | 680 mcg DFE | — | |
| Vitamin B12 (as cyanocobalamin) | 30 mcg | — | |
| Iron (as fermented iron bisglycinate) | 26 mg | — | |
| Organic beetroot | 125 mg | — | |
| Food Blend | 30 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out2
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
The review count moved gradually, not in one burst
Written reviews rose from 1,516 to 1,744 between August 4, 2025 and August 25, 2026. The largest rise inside any single 30-day window was about 31, so the count moved in steps rather than in one burst.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
What is still missing4
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Listing claim matches the label panel
The listing claims 26 mg; the photo-read Supplement Facts panel shows Iron (as fermented iron bisglycinate) at 26 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
FDA recall appears in this brand's history
This recall is not about the product on this page. FoodState, Inc recalled a different product on April 15, 2016. FDA has since closed that case. The recalled item was “MegaFood Multi for Women 40+, Multivitamin & Mineral Dietary Supplement packaged in glass bottles UPC:5149410321 -Packaged 60 tablets; UPC:5149410322 -Packaged 120 tablets”. FDA recorded the reason as “Multi Vitamin label fails to have required warning statement for iron and child resistant cap”. Verify at FDA’s recall database.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,511 on 2025-07-30 to 1,744 on 2026-08-25 (net +233). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
2
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
3
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
What the listing promises — claim by claim
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…Clinically shown to increase iron levels without side effects…” | No evidence located We looked for: a named, citable clinical study of this product or formula | 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. |
| Manufacturing claim “…Non-GMO Project verified, vegan, and kosher; The iron vitamin tablets are made without gluten, dairy, eggs, tree nuts, peanuts, soy, fish, shellfish or sesame in a GMP f” | Partly supported We looked for: the facility registration or certificate behind the claim | “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. |
| Benefit claim “MegaFood Blood Builder Iron Supplement for Women & Men – Increase Iron Levels Without Side Effects – Improves Energy Levels – B12, Folic Acid & Vitamin C for Absorption –” | Not checked yet We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not checked yet — not as a negative. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.

Where it sells
We found a brand storefront, but we could not match any price on it to this exact product when we checked.
Brand store megafood.com: 100 supplement products (+7 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
