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
8listed rows
7separately quantified
1combined blend totals
The listing-image panel publishes 7 separately ingredients with amounts and 1 combined blend total. Ingredients inside a blend do not have separate amounts.

|---|---|---|---|
| Vitamin C (as Ascorbic acid) | 90 mg | — | |
| Vitamin D3 (as Cholecalciferol) | 50 mcg (2000 IU) | — | |
| Magnesium Blend (as Magnesium Glycinate, Oxide, and Citrate) | 400 mg | — | |
| Ashwagandha (Withania Somnifera) (Root) Extract (20:1) | 300 mg | — | |
| L-Theanine | 200 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.

Every check we ran
Confirmed evidence
What checked out2
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
The review count moved gradually, not in one burst
Written reviews rose from 50 to 407 between August 5, 2025 and August 24, 2026. The largest rise inside any single 30-day window was about 42, so the count moved in steps rather than in one burst.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
What is still missing7
We looked for these signals but could not settle them from public sources. A gap is not a strike.
“Lab tested” claimed, but no lab or report named
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
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 magnesium, ashwagandha 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
No recall found — which is not the same as being tested
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
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 47 on 2025-07-29 to 407 on 2026-08-24 (net +360). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Package and trademark records name different responsible entitie
The package says manufactured for: STRONGVIT LLC, 1704 Llano St Ste B Santa Fe, NM 87505. USPTO names Arsene, Mihaela-Georgiana as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
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
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
2
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
3
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.
4
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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
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 |
|---|---|---|
| Quality-testing claim “…Third-Party Lab Tested in the USA – Our Cortisol supplement pills are rigorously tested by Swift Laboratory for purity and potency.…” | Claimed, not verifiable We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, 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. |
| Manufacturing claim “…GMP CERTIFIED…” | Partly supported We looked for: the facility registration or certificate behind the claim | “GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check. |
| Benefit claim “…Sleep Support & Stress Relief, USA…” | 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. 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?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Magnesium Blend (as Magnesium Glycinate, Oxi | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 400 mg — within the studied range |
| Ashwagandha (Withania Somnifera) (Root) Extr | shaded = doses used in studies (250 mg–600 mg) · bar = this label | 300 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
- magnesium — daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
