“muscle strength and mass, and cellular repair, especially for those who work indoors or lack adequate sun exposure to support the body's natural…”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.
Evidence →We looked and found no public proof. That does not count against the product.

CheckedIs the label honest?
Every ingredient shows its amount · 2 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

The barcode identity checks out · 693749128014.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 693749128014 to "THORNE" (Thorne Research) — consistent with this listing.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
We can see 34 of this product’s 212 reviews — the count rose between August 11, 2025 and August 26, 2026. That is too small a slice to say anything about the wider pattern.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 178 to 212 between August 11, 2025 and August 26, 2026. The largest rise inside any single 30-day window was about 7, so the count moved in steps rather than in one burst.
