Checked against public sources between July 23 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Package and trademark records name different responsible entities. The package says distributed by: Carson, Lincolnshire, IL 60. USPTO names J.R. Carlson Laboratories, Inc. as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship…
“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 2 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.
No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. 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.
