Maennyliy Vitamin D3 K2 Gummies for Adults: D3 5000IU + K2…

Checked against public sources on August 15, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

The label says 3.35 g of omega-3 in 4 gummies — but not what those 4 gummies weigh. That weight is the one number that would let anyone check the amount on the front. We did not weigh it ourselves, so this is an open question, not a problem we found.

Is the dose real?Panel read — dose not verified14 ingredients listed; no advertised amount we could confirm against them
What a serving costsNo price found for this exact barcode
Is it tested?Claimed — no lab or certificate found
Who’s behind it?No exact match in USPTO
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
Trouble on record?No recalls found

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed1

“it's fortified with 250 mg of Omega-3 to enhance the absorption of fat-soluble vitamin k2 d3 in the”

The panel lists 500 mg EPA + DHA per serving (2 Gummies). One randomized dose-response trial used 300–1,800 mg/day; omega-3 studies vary widely. This is research context, not a recommendation or safety verdict.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently1

“TESTED”

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.

Evidence →

We looked and found no public proof. That does not count against the product.

The label says 3.35 g of omega-3 in 4 gummies — but not what those 4 gummies weigh

That weight is the one number that would let anyone check the amount on the front. We did not weigh it ourselves, so this is an open question, not a problem we found.

Evidence and sources

A serving is 4 gummies, and the panel lists 3,350 mg — 3.35 g — of omega-3 in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of…

CheckedIs the label honest?

Every ingredient shows its amount · 14 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

Evidence and sources

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

CheckedCan you trust the review pattern?

Reviews rose from 23 to 38 between August 9, 2025 and July 11, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 23 to 38 between August 9, 2025 and July 11, 2026. The largest rise inside any single 30-day window was about 4, so the count moved in steps rather than in one burst.

  • No FDA recall matched this brand in the current search.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 250 mg of omega-3 (EPA + DHA) per serving. Studies we found used 300 mg–1.8 g a day, so this sits below that range.

0studied 300 mg–1.8 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The panel lists 100 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.

0studied 200 mg–420 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The panel lists 10 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
