“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 label itself
What the Supplement Facts panel says
| Zinc (as zinc mono methionine chelate complex) | 22 mg |
|---|---|
| Quercetin (as quercetin dihydrate) | 800 mg |
| Japanese sophora (Sophora japonica) (flower buds) extract | not stated separately |
The label groups several ingredients under “Zinc (as zinc mono methionine chelate complex)” and publishes only the combined total, so there is no way to tell how much of each one a serving contains. That is the manufacturer’s choice, not a gap in our reading.
Printed on the package: THIRD PARTY LAB TESTED · Healthy Immune Function* · Supports Respiratory Health* · Vegetarian · Science backed formula · Third-party lab tested · Third Party Tested · Research Based Nutrition
We read 6 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.

The public sources did not settle the marketing promises on this label.
◐Partly confirmed3
“to swallow, third party tested & made in NSF-GMP Certified facility in the”
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.
“to swallow, third party tested & made in NSF-GMP Certified facility in the”
Evidence →A testing body is named on the listing, but we found no lot-specific certificate of analysis.
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently1
“IN USA WITH GLOBALLY”
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 22 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
