Marketing claims, checked

The checks, one by one

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

Partly confirmed2

“TESTED, MADE IN USA, & VEGETARIAN: This formula is manufactured in the USA in an FDA registered cGMP facility and 3rd party tested by Labdoor for…”

A testing body is named on the listing, but we found no lot-specific certificate of analysis.

Evidence →
“works perfectly with Vitamin D3 to support healthy muscles, strong bones, and more without any laxative”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently1

“TESTED, MADE IN USA, & VEGETARIAN: This formula is manufactured in the USA in an FDA registered cGMP facility and 3rd party tested by Labdoor for…”

“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.

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

CheckedIs the label honest?

Every ingredient shows its amount · 6 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 · 791259719378.

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

Evidence and sources

UPCitemdb resolves 791259719378 to "FarmHaven Magnesium Glycinate & Malate Complex w/Vitamin D3 100% Chelated for M" (FarmHaven) — 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 250 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.
