Magnesium Glycinate Powder + L Theanine

Does the marketing hold up?

Testing claimed — documentation not found. The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. …

“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.

Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“paired with L-theanine, an amino acid known for its ability to promote relaxation and clarity, the benefits”

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 independently2

“IN USA - Say no to artificial additives and”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →
“magnesium-glycinate is 3rd party tested for maximum quality and”

No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. 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.

Evidence →

We looked and found no public proof. That does not count against the product.

What is worth knowing.

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

CheckedIs the label honest?

Every ingredient shows its amount · 4 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.

CheckedCan you trust the review pattern?

Reviews rose from 104 to 187 between July 27, 2025 and July 29, 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 104 to 187 between July 27, 2025 and July 29, 2026. The largest rise inside any single 30-day window was about 16, so the count moved in steps rather than in one burst.

What remains open 3
  • No FDA recall matched this brand in the current search.
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

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 300 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.
