“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.

The checks, one by one

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

Partly confirmed2

“FDA Registered Facility DIETARY SUPPLEMENT THIRD PARTY TESTED NON-GMO GLUTEN-FREE MADE AND QUALITY”

A testing body is named on the listing, but we found no lot-specific certificate of analysis.

Evidence →
“Soy Free, and Made in a NSF Certified GMP Compliant, FDA Registered Facility DIETARY”

“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.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.
