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.
Panel, decoded
What the label discloses
7listed rows
7separately quantified
0combined blend totals
The listing-image panel publishes an amount for each of its 7 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Total Carbohydrate | <1 g | — | |
| Sodium | 10 mg | — | |
| Bacopa (Bacopa monnieri) whole plant extract | 380 mg | — | |
| Lion's Mane (Hericium erinaceus) mycelium+/fermented brown rice biomass | 300 mg | — | |
| Reishi (Ganoderma lucidum s.l.) mycelium+/fermented brown rice biomass | 150 mg | — | |
| Ginkgo (Ginkgo biloba) leaf extract | 120 mg | — | |
| Cordyceps (Cordyceps militaris) mycelium+/fermented brown rice biomass | 50 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “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 listed amounts are independently verified and how they compare with relevant research.
vision:google/gemini-2.5-flash Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
What checked out1
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Documented concerns
What needs caution0
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
What is still missing6
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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.
FDA recall appears in this brand's history
This recall is not about the product on this page. Fungi Perfecti LLC recalled a different product on February 28, 2019. FDA has since closed that case. The recalled item 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”. FDA recorded the reason as “Host Defense MycoBotanicals Blood Sugar, 60 ct. bottles, is recalled due to undeclared wheat”. Verify at FDA’s recall database.
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.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 267 on 2025-06-26 to 322 on 2026-07-10 (net +55). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Scan the barcode on the package and confirm it reads 633422038629.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
3
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
What the listing promises — claim by claim
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “Host Defense MycoBotanicals Brain* Capsules - Brain Support Supplement with Lion's Mane, Reishi & Cordyceps Mushroom - Herbal Supplement for Memory & Focus Support - 60 C” | Not checked yet 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 checked yet — 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.

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.
