The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“formulations are crafted in GMP-compliant facilities right here in the United States, ensuring the same Nutritarian standard of clean, transparent…”
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.
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently1
“in USA”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count 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.
