Vitamin B12 prices

2 sellers, 2 listings, 2 vial sizes, read from each store's public product feed on 2026-09-30. A seller with a recent certificate from a named lab ranks above a cheaper one without. Every card says why it sits where it does.

No public certificate file we opened names Vitamin B12 in its address or in the sample note. That is a count of files, not a grade, and compounds are not ranked against one another. A seller-published certificate is not a blind test. Certificate search.

Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.

Week by week

Vitamin B12 was first read on 2026-09-30. Middle price $2.79 per milligram across 2 sellers. A week-by-week line appears after the next finished weekly walk. One week is a snapshot, not a history.

The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.

How the ranking works

LC
Lab-confirmed: the issuing laboratory echoed this certificate back
A
Current certificate, independent laboratory named, laboratory not yet checked
B
Certificate published, but no laboratory link, older than a year, or the laboratory did not recognise the published lookup
C
No certificate could be read
  • Grade first, then price per milligram within the grade. A cheap vial that is not the real compound is not cheap, so no price moves a seller above a better certificate. Sort by price if you want price alone. The grade stays on the card.
  • The grade is what we could read on the seller's site on the date shown, not what the seller claims. If a login page or a robot block hid the certificates, the card says so. A later check in a normal browser may raise that grade.
  • Prices are list prices before any discount code, shipping, tax or customs. Multi-vial packs are counted at their total milligrams, and their per mg price reflects that.
  • The dot on each card shows where that price sits between the cheapest and the priciest seller of the same vial. The tick is the middle price. A bigger vial's lower price per mg is never mistaken for a better seller.
  • Every seller links to its own page: the company behind it, address, store platform, labs named, a sample certificate, shipping and payment terms, and every warning sign we found.

We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
