Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Is the dose real?Panel read — dose not verified3 ingredients listed; no advertised amount we could confirm against them
What a serving costs$0.79per serving, at the checked price
Is it tested?No testing claim made
Who’s behind it?USPTO lists 3 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?✓Barcode matches outside records
Trouble on record?Brand history — not this product
“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.

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources

Registered owner records: Turtle Bear Holdings, LLC · Stamets, Paul
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources
USPTO returned multiple live supplement-class records for the exact brand wordmark: Turtle Bear Holdings, LLC, Stamets, Paul. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

The barcode identity checks out · 633422027333.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 633422027333 to "Mushroom turkey tail" () — consistent with this listing.
Locked evidence record →Open the full source-linked findingChecks outCan you trust the review pattern?
Reviews rose from 527 to 550 between February 13 and July 21, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 527 to 550 between February 13 and July 21, 2026. The largest rise inside any single 30-day window was about 15, so the count moved in steps rather than in one burst.
