“GMP”
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.
“Magnesium Support: Each serving delivers 400 MG of Magnesium, providing fundamental support for various bodily”
Evidence →Ingredient evidence exists; on dose: label states 400 mg/serving — about 95% of the adult daily reference (adult RDA 310–420 mg elemental; NIH sets 350 mg/day as the supplemental upper level for elemental magnesium). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate labels (glycinate, citrate) often state compound mass, which reads ~5–7× higher than elemental magnesium — the Supplement Facts panel settles which is meant.
Ingredient research can support context, but it is not a trial of this exact product.

Evidence →No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
We looked and found no public proof. That does not count against the product.

CheckedIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 400 mg; the photo-read Supplement Facts panel shows Magnesium (from Magnesium Bisglycinate) at 400 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

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.

Reviews rose from 35 to 231 between July 3, 2025 and July 23, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 35 to 231 between July 3, 2025 and July 23, 2026. The largest rise inside any single 30-day window was about 45, so the count moved in steps rather than in one burst.

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.
