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
The 0.05 mg vitamin k2 claim matches the panel
MARKETING0.05 mg — per-serving claim
PANELVitamin K2 0.05 mg — same amountSaturated Fat 500 mg + Medium-chain triglycerides 704.8 mg
matches panelWe did the comparison: the listing claims 0.05 mg of vitamin k2, and the listing-image panel shows 0.05 mg vitamin k2 one dropperful (0.75 ml). Those amounts agree. This is internal consistency, not independent lab testing.

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; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out5
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Full label filed with NIH — ingredients on public record
Label #238879 “MCT Oil” (Dr. Berg Nutritionals), entered 2020-10-23, with the full Supplement Facts on file. Company on file: Manufacturer — Dr. Berg Nutritionals, Alexandria, VA.
Every ingredient amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Exact trademark owner identified
USPTO lists The Health & Wellness Center Inc. (CORPORATION) in VIRGINIA, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
The review count moved gradually, not in one burst
Written reviews rose from 0 to 124 between August 17, 2025 and July 27, 2026. The largest rise inside any single 30-day window was about 26, so the count moved in steps rather than in one burst.
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 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.
Listing claim matches the label panel
The listing claims 0.05 mg; the photo-read Supplement Facts panel shows Vitamin K2 at 0.05 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
FDA recall appears in this brand's history
This recall is not about the product on this page. Health & Wellness Center, Inc. recalled a different product on September 24, 2021. FDA has since closed that case. The recalled item was “Dr. Berg Nutritionals, Liquid Vitamin D with Zinc Dietary Supplement ( Liquid Vitamin D ), Individual 1 FL OZ bottle (with no secondary packaging), Glass bottle. The label of t”. FDA recorded the reason as “Product recalled because of the presence of mold and/or yeast found in amounts that exceed the product's established specifications ”. Verify at FDA’s recall database.
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 0 on 2025-08-17 to 124 on 2026-07-27 (net +124). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 810110791169 to "Vitamin D3 & K2 With Mct Oil" (Dr. Berg), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
Package and trademark records name different responsible entitie
The package says distributed by: Dr. Eric Berg DC, Dr. Berg Nutritionals, 4501 Ford Avenue, Alexandria, VA 22302. USPTO names The Health & Wellness Center Inc. 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
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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 810110791169.
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 |
|---|---|---|
| Quality-testing claim “…These D3 K2 liquid drops are third-party tested in a GMP-certified facility.…” | 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 “…These D3 K2 liquid drops are third-party tested in a GMP-certified facility.…” | 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. |
| Origin claim “…PROUDLY MADE IN USA” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…Berg Maximum Strength Vitamin D3 K2 Liquid Drops with MCT Oil – 5,000 IU Liquid Vitamin D3 with K2 – Supports Strong Bones, Heart, Energy, Immunity, and Overall Vitality” | 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.
