Dr. Berg Maximum Strength 7-in-1 Vitamin D3 K2 5000 IU
Checked against public sources on July 26, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
“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.

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
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 )…”
Locked evidence record →Open the full source-linked findingThe headline amount is not tied to a panel row for the same ingredient
You are being sold on an ingredient the verified panel does not separately declare. The brand should explain the mismatch.
Evidence and sources
The listing presents 0 mg for vitamin k2, but vision:google/gemini-flash-1.5 does not contain a same-name quantified row. The saved image read may be incomplete, so this is a specific question to resolve rather than a contradiction.
Locked evidence record →Open the full source-linked findingThe barcode identity checks out · 810110790056.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
UPCitemdb resolves 810110790056 to "Dr. Berg D3 & K2 Vitamin Supplement - D3 K2 5000 IU 60 Capsules" (Dr. Berg) — consistent with this listing.
Locked evidence record →Open the full source-linked findingReviews rose from 1,619 to 1,918 between February 19 and July 24, 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 1,619 to 1,918 between February 19 and July 24, 2026. The largest rise inside any single 30-day window was about 80, so the count moved in steps rather than in one burst.
