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.

THORNE - ResveraCel - Nicotinamide Riboside with Quercetin…
Checked against public sources between July 25 and September 2, 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.
