“Quality”
Evidence →“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.

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.
Is the dose real?Panel read — dose not verified1 ingredient listed; no advertised amount we could confirm against them
What a serving costs$0.44per serving, at the checked price
Is it tested?No testing claim made
Who’s behind it?USPTO lists 3 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?✓Barcode matches outside records
Trouble on record?Brand history — not this product
“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. Nestle Product Technology Center - Nestle Health Science recalled a different product on December 22, 2023. FDA has since closed that case. The recalled item was “Solgar, Triple Strength, Shellfish -Free, Glucosamine Chondroitin…”

The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources

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.

The barcode identity checks out · 033984594333.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
UPCitemdb resolves 033984594333 to "Solgar - Chelated Magnesium - 250 Tablets" (Solgar) — consistent with this listing.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
We can see 27 of this product’s 331 reviews — the count rose between July 9, 2025 and July 20, 2026. That is too small a slice to say anything about the wider pattern.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 304 to 331 between July 9, 2025 and July 20, 2026. The largest rise inside any single 30-day window was about 4, so the count moved in steps rather than in one burst.

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.
