Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“MANUFACTURED & 3RD PARTY TESTED: This NatureWise supplement is manufactured in the USA in a facility that follows cGMP and undergoes independent…”

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

Evidence →

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

?Couldn’t verify independently1

“MANUFACTURED & 3RD PARTY TESTED: This NatureWise supplement is manufactured in the USA in a facility that follows cGMP and undergoes independent…”

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

Evidence →

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