Is Vitamin K2 legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Vitamin K2 can be sold in Canada as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: Health Canada has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

- 02

What Vitamin K2 is
The K2 half of the owner's D3 plus K2 floor pairing. Observational menaquinone intake tracked with less coronary heart disease in Rotterdam. A three-year MK-7 trial reported less bone loss in healthy postmenopausal women. Warfarin is a hard stop.
Vitamin K2 is a family of menaquinones, most often sold as MK-7. The owner takes it beside vitamin D3.
Mechanism: Vitamin K is a cofactor for gamma-carboxylation of vitamin-K-dependent proteins, including clotting factors and osteocalcin. MK-7 is a long-chain menaquinone with a longer circulating half-life than MK-4.
Regulatory history: Sold as a dietary supplement in the United States. Not approved to prevent heart disease or fractures. Warfarin remains a prescription anticoagulant that K2 can disturb.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Vitamin K2 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
