One A Day Prenatal Vitamins- Folic Acid

The panel publishes 24 amounts, led by Calcium 150 mg, Omega-3 Fatty Acids (from fish oil) 235 mg.

Rebuilt from public sources on July 22, 2026 · evidence availability is not a safety or effectiveness verdict.

What this means for you · What checks out

What the record confirms

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Panel, decoded

The 235 mg omega-3 fatty acids (from fish oil) claim matches the panel

MARKETING235 mg — listing title
PANELOmega-3 Fatty Acids (from fish oil) 235 mg — same amountCalcium 150 mg + Omega-3 Fatty Acids (from fish oil) 235 mg + DHA (docosahexaenoic acid) 200 mg
matches panel

We did the comparison: the listing claims 235 mg of omega-3 fatty acids (from fish oil), and the listing-image panel shows 235 mg omega-3 fatty acids (from fish oil) one softgel. Those amounts agree. This is internal consistency, not independent lab testing.

Dose vs research

0.235 g declared

The panel declares 235 mg EPA + DHA per serving, below one studied 300–1800 mg/day context. The fish-oil concentrate total is not substituted for EPA + DHA.

Confirmed evidence

What checked out02

These checks found support in the public record. They confirm specific facts, not the product as a whole.

Every ingredient amount is disclosed

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Confirmed

Exact trademark owner identified

USPTO lists Bayer HealthCare LLC (LIMITED LIABILITY COMPANY) in DELAWARE, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.

Documented concerns

What needs caution00

These are documented contradictions or claims that need more evidence. They are separate from missing data.

No contradictions or product-specific cautions were found at this check depth.

Unresolved public record

What is still missing06

We looked for these signals but could not settle them from public sources. A gap is not a strike.

Review-count history: not available

Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.

No data

EPA + DHA dose is below one studied range

The panel declares 235 mg EPA + DHA per serving (One 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.

No data

Multi-ingredient formula — panel read, serving weight unknown

We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.

No data

Research context is available for the listed ingredients

Published sources describe how omega-3, magnesium, zinc have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Omega-3 Fatty Acids fact sheet, PubMed dose-response trial.

No data

No label filed with NIH's public catalog

The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.

No data

UPC valid, no independent record

Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.

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

Answered by the panel: the 0.235 g listing number equals Thiamin (B1) 1.4 mg + Omega-3 Fatty Acids (from fish oil) 235 mg. What lot-specific document confirms those declared amounts?

The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those declared amounts; ask for a lot-specific certificate of analysis.

2

Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?

Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.

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

Scan the barcode on the package and confirm it reads 016500563907.

A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.

3

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.
