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 1 separately quantified row and 2 combined blend totals. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Zinc (as Zinc Picolinate) | 15 mg | — | |
| DHT Blocker Proprietary Blend Saw Palmetto Extract (45% Fatty Acids) (Serenoa repens) (fruit), Green Tea Extract (98% Polyhenols, 65% Catechins, 45% EGCG) (Camellia sinensis) (leaf), Stinging Nettles (Urtica dioica)(leaf), L-Lysine HCI, Grape Seed Extract (95% Proanthocyanidins) (Vitis vinifera), Pygeum Bark Extract (Pygeum africanum), Pumpkin Seed Extract 4:1 (Cucurbita moschata) | 1365mg | — | |
| Immune/Digestive Proprietary Blend Grapefruit Seed Extract (Citrus paradisi), Chicory Root Extract (Cichorium intybus), Lactobacillus Acidophilus Complex (15 Billion/CFU) | 525 mg | — |
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
Ingredient amounts are hidden inside a blend
The panel lists “DHT Blocker Proprietary Blend Saw Palmetto Extract (45% Fatt” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
No data yet: Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
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.
Research context is available for the listed ingredients
Published sources describe how zinc have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Zinc fact sheet, PubMed search: zinc supplementation trial.
Public label filing not retained
This record does not currently hold an identity-bound public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
Barcode record is too sparse to confirm identity
UPCitemdb resolves 705105258874 to "Grow Vitamin Hydrolyzed Collagen Powder for Skin Hair Nails - 56 Servings" (Grow Vitamin), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Manufacturing claim “…TEED GLUTEN FREE FDA Registered Manufacturer GMP WHEAT FREE MADE IN CALIFORNIA VEGETARIAN” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Benefit claim “…health, hair loss control, and immune system support. Gluten-free vegetarian clinically developed…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed. |
“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.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Zinc (as Zinc Picolinate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 15 mg — within the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
Documented cautions

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store advancedtrichology.com: 42 supplement products (+2 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.
