“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.

Naturelo Plant-Based Magnesium Glycinate Complex…
Checked against public sources on July 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
No individual ingredient amount is published — every figure is a blend total. Every amount on this panel is a blend total: Magnesium (from 513 mg Buffered Magnesium Glycinate Chelate Complex [Magnesium Oxide and Magnesium Bisglycinate]); Magnesium-Rich Plants Blend*. …
“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.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
Magnesium
200 mg per serving — within the 200–420 mg/day used in the linked studies.
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 200 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
