Checked against public sources on July 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Testing claimed — documentation not found. The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. …
“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 11 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
1 promise needs a closer look.
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.
We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this 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. Under NSF/ANSI 173, NSF lists Thorne® products, including Thorne® L-Glutamine Powder, but not this exact SKU. 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.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Open Food Facts resolves 693749013112 to "Collagen Powder" (THORNE) — consistent with this listing.

USPTO identifies the public owner or applicant behind this brand wordmark. This does not by itself identify the product manufacturer or prove where the product was made. Open USPTO source ↗
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 13 g of collagen peptides per serving. Studies we found used 2.5 g–15 g a day, so this sits inside that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
