Does the marketing hold up?

FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

“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.

FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Evidence and sources

This recall is not about the product on this page. Bluebonnet Nutrition Corporation (Dairy Ashford) recalled a different product on January 12, 2024. FDA has since closed that case. The recalled item was “EarthSweet¿ Chewables CellularActive¿ Methylfolate 1000 mcg; 90 chewable…”

CheckedIs the label honest?

Every ingredient shows its amount · 1 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 · 743715007499.

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

Evidence and sources

UPCitemdb resolves 743715007499 to "Magnesium Glycinate 400mg per serving 120 Vegetable Capsules" (Bluebonnet) — consistent with this listing.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

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 400 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside 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.
