Does the marketing hold up?

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

Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“One A Day Prenatal Vitamins- Folic Acid, Iron, Omega- 3 (DHA), Pregnancy Vitamins for Women, Prenatal Multivitamin for Mom and Baby Support,…”

The panel lists 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.

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 235 mg of omega-3 (EPA + DHA) per serving. Studies we found used 300 mg–1.8 g a day, so this sits below 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 panel lists 40 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.

0studied 200 mg–420 mg

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

The panel lists 13 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
