Is Niacin legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
No. Niacin is not an approved medicine in Canada. Its legal category is "Prescription slow-release product was once available; also sold as a supplement". Nothing that contains it is allowed for any use in people. Vials labeled "for research use only" get no exception: that label does not make them legal to use in people. On the evidence, 2 completed human trials are cited on its profile.

Doctors have largely stopped using it to prevent heart disease, because of the large studies that counted heart attacks and deaths.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
No product containing Niacin is approved by Health Canada for any use in Canada. So nothing on sale is allowed for use in people.
- 02
"Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.
- 03
Importing it, supplying it or promoting it for use in people can fall under medicines law in Canada. This page is general information, not legal advice.
What Niacin is
The only NAD-pathway product ever tested against real heart outcomes, in 25,673 people in HPS2-THRIVE and 3,414 in AIM-HIGH. It moved every blood fat it was meant to move. It prevented no heart attacks or strokes in either study. In HPS2-THRIVE it caused extra serious side effects, including infections and bleeding.
If you want to see why a moving blood number is not proof, study this one. Nothing else sold for longevity has been tested this hard against outcomes that matter.
How it works: Niacin gets turned into NAD by its own route, called the Preiss-Handler pathway, not the NAMPT recycling route. That is why it is a strong NAD booster.
Approval history: Slow-release nicotinic acid is an FDA-approved prescription cholesterol drug in the United States. But doctors mostly stopped using it after two large studies, AIM-HIGH and HPS2-THRIVE. Lower-dose nicotinic acid is also sold over the counter as a supplement. The mix of slow-release niacin and laropiprant tested in HPS2-THRIVE was pulled from sale worldwide after that study reported.
How Health Canada treats this kind of product
Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.
The legal category above is how The Longevity Archive reads Health Canada, Health Products and Food Branch listings for Niacin on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Niacin in sport and the military
Whether Niacin is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Canada. Before you compete or get tested, look up Niacin by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
