Checked against public sources on August 1, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside “Clean Q-Defend™ Immune Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.
“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.

We read 7 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.
Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
We looked and found no public proof. That does not count against the product.
Headlines first. Open evidence only when you want the source trail.
This serving is about 1.2× the adult upper limit shown by NIH. The limit applies to adults; 100 mcg = 4,000 IU.
The panel lists 125 mcg vitamin d. NIH gives 100 mcg as the adult Tolerable Upper Intake Level for adults; 100 mcg = 4,000 IU. That is about 1.2 times the limit.
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
USPTO returned multiple live supplement-class records for the exact brand wordmark: ALLSEASON ENTERPRISES LLC, ALLSEASON IPCO, LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

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.
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 50 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
Only the submitted seller page is identity-certain. Other destinations are shown as leads until a shared UPC/GTIN confirms the exact product.
