How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
What the label discloses
The listing-image panel publishes an amount for each of its 3 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 5 | — | |
| Total Carbohydrate | <1 g | — | |
| Lion's Mane (Hericium erinaceus) mycelium+/fermented brown rice biomass+ | 1 g | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
No data yet: Multiple USPTO brand-owner records are shown
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.
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Fungi Perfecti LLC recalled a different or not-exactly-bound product on 2019-02-28: “Host Defense MycoBotanicals Blood Sugar, 60 ct. bottles, is recalled due to undeclared wheat.” (status: Terminated). The recalled product was: “Host Defense MycoBotanicals Blood Sugar, dietary supplement, 500mg capsules, 60 ct per bottle, serving size 2 capsules per day. UPC: 6 33422 70474 6 (distributed in US) UPC: 8 ” — not necessarily the product on this page. Verify at FDA’s recall database.
180-day review-count history is on file
Exact-listing history records written-review counts from 789 on 2026-01-23 to 823 on 2026-07-21 (net +34). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…Immunologically Supportive Unique Compounds Clinically Studied Cutting Edge Research NON GMO CERTIFIED ORGA…” | No evidence located We looked for: a named, citable clinical study of this product or formula | No named, citable study of this product or formula was located in public sources. The claim may rest on ingredient-level research rather than a trial of this product. |
| Benefit claim “…Mane - Supplement Capsules for Brain Health Support - Mushroom Support for Focus & Memory Functi…” | Not assessed We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not assessed — not as a negative. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
Verifiability profile — 2 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store hostdefense.com: 41 supplement products (+22 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
Reference links for identification only — LookCloser has no affiliate relationships and earns nothing from any link on this page.
Ingredient science
No knowledge-base entry yet for this formula's active ingredients — entries are added as the KB grows. Absence of a science card is a coverage gap, not a judgment.
