Natural Health Product Regulations Canada: A Guide for Brands
Natural health product regulations in Canada come down to one rule: you can’t sell a vitamin, herbal remedy, probiotic or homeopathic medicine here until Health Canada has licensed it and assigned it an eight-digit NPN (or a DIN-HM for homeopathics). The sites that make, package, label or import it need their own licence too, and they have to follow good manufacturing practices. Everything else, from your label layout to your Instagram captions, has to stay inside the terms of that licence.
Below is each obligation, who carries it and the dates to put in your calendar.
Key takeaways
- Every NHP sold in Canada needs a product licence (NPN or DIN-HM) under the Natural Health Products Regulations, SOR/2003-196.
- Manufacturers, packagers, labellers and importers each need a site licence and must meet good manufacturing practices (GMP).
- New labelling rules, including a Product Facts table, came into force June 21, 2025. Most products have until June 2028 to comply.
- Since June 22, 2023, Vanessa’s Law powers (mandatory recalls, label changes, fines up to $5 million) apply to NHPs.
- Cost recovery fees for NHPs have been proposed but, as of late 2025, not implemented.

What counts as a natural health product in Canada?
A natural health product is a substance from Schedule 1 of the Natural Health Products Regulations, a homeopathic medicine or a traditional medicine, sold to diagnose, treat, mitigate or prevent a disease, or to restore or modify an organic function in people. In plain terms, it’s a health product that makes a health claim and is built from ingredients like these.
Schedule 1 covers plant and algae material, fungi, vitamins, minerals, amino acids, essential fatty acids, probiotics and synthetic copies of those substances. Schedule 2 lists what’s excluded, such as prescription drug ingredients, controlled substances, tobacco and anything given by injection.
The grey zone is where brands get tripped up. A protein bar with a “supports muscle recovery” claim may be a food. A capsule of the same protein with a dose and a health claim is probably an NHP. Settle the classification before you design packaging.
What is an NPN, and how do you get one?
An NPN (Natural Product Number) is the eight-digit number Health Canada assigns when it issues a product licence. Homeopathic medicines get a DIN-HM instead. Either one has to appear on the label, and selling without it is illegal.
You apply through a product licence application (PLA) that sets out medicinal and non-medicinal ingredients, dose, recommended use, risk information and supporting evidence. Health Canada sorts applications into three classes, based mostly on how closely they follow its published monographs (pre-cleared “recipes” for ingredients like vitamin D or melatonin).
- Class I: fully matches every parameter of a single monograph. Service standard: 60 calendar days.
- Class II: attests to one or more monographs, with deviations assessed against them. Service standard: 90 calendar days.
- Class III: anything outside monographs, where you supply your own safety and efficacy evidence. Service standard: 210 calendar days.
Those are Health Canada’s targets from its Management of Applications Policy, not guarantees. A vague claim or missing ingredient source can trigger an information request and add weeks. If your product fits a monograph, stick to it. A single-ingredient magnesium glycinate formula at monograph doses is a far faster file than a novel eight-botanical blend.
Who needs a site licence?
Any business that manufactures, packages, labels or imports NHPs for sale in Canada needs a site licence. The product licence belongs to whoever owns the brand. The site licence belongs to each place where the physical work happens.
If you’re a brand owner using a contract manufacturer, the manufacturer holds its own site licence. But if you import finished goods, you need a site licence as the importer and you must show that your foreign supplier meets GMP standards equivalent to Part 3 of the Regulations. Think audit reports, a quality agreement and certificates of analysis.
GMP covers specifications, premises, equipment, personnel, sanitation, operations, quality assurance, stability, records, lot samples and recall procedures. Health Canada’s updated GMP guide for NHPs (GUI-0158, version 4.0) was published September 4, 2025 and took effect March 4, 2026. It adds clearer expectations for importers, so it’s worth rereading if your quality system was built on the 2015 version.
What changed with NHP labelling?
Amendments registered in July 2022 overhauled NHP labels (Health Canada summarizes them on its improved labelling page). They came into force June 21, 2025, and most products have until June 2028 to comply.
The main changes:
- A standardized, bilingual Product Facts table listing medicinal ingredients, uses, warnings, directions, other information and non-medicinal ingredients.
- Priority allergen, gluten and added sulphite declarations (sulphites at 10 ppm or more).
- Minimum type sizes and better contrast so key text is readable.
- Modernized contact information, including the option of a website.
Products licensed before June 21, 2025 have until June 22, 2028. Newly licensed products were originally expected to comply right away, but a ministerial exemption order (SOR/2025-94) lets products licensed between June 21, 2025 and June 21, 2028 use either the old or new format until the order expires. Our advice: design new packaging to the new rules now.
What can you say in health claims and advertising?
Your claims have to match your licence. If your NPN says “helps support sleep,” your ad can’t say “cures insomnia.” Advertising also can’t be false, misleading or deceptive, and that includes social posts, influencer content and product page copy.
Two rules catch marketers most often:
- Section 3 and Schedule A of the Food and Drugs Act restrict advertising to the general public as a treatment or cure for listed serious diseases. NHPs have a narrow exception for preventive claims authorized through licensing.
- Testimonials and before-and-after content are still your advertising. If an influencer implies something your licence doesn’t allow, it’s your problem.
Preclearance of consumer ads by an independent agency such as Ad Standards is voluntary, but Health Canada strongly recommends it. More on this in our regulation and compliance section.
What are your adverse reaction and recall duties?
Product licence holders must report serious adverse reactions that happen in Canada within 15 days of learning about them. The same 15-day clock applies to serious unexpected reactions anywhere in the world.
You also have to prepare an annual summary report analysing all adverse reactions, and keep it on file. For recalls, manufacturers, importers and distributors must notify Health Canada within three days of starting one. Route customer service emails and social DMs into one complaint log so nothing sits unread past day 15.
How did Vanessa’s Law change enforcement?
Since June 22, 2023, NHPs count as “therapeutic products” under the Food and Drugs Act. That change came through the 2023 budget legislation (Bill C-47) and gives Health Canada the same Vanessa’s Law powers it has over drugs.
Health Canada can now order a recall when a product presents a serious or imminent risk, require label changes, compel information and order tests or studies. Fines can reach $5,000,000, with prison terms possible for the worst offences. Recalls are no longer just voluntary.
Are there Health Canada fees for NHPs?
Not yet. Health Canada proposed cost recovery fees for product licence reviews, site licences and an annual right-to-sell fee in May 2023, then published revised amounts in March 2024.
As of its November 2025 update, the fees haven’t been implemented, and the department says it will revisit the proposal after its red tape reduction work, which it outlined in a September 2025 report. Final fees must be published in the Canada Gazette, Part II before they apply. Budget for them in your three-year plan, but don’t treat old proposed figures as final.
NHP compliance at a glance

| Cost recovery fees | Applicants and licence holders (once in force) | Watch the Canada Gazette; budget for future fees |
How is this different from US supplement rules?
Very different. Under the US Dietary Supplement Health and Education Act (DSHEA), the FDA doesn’t approve supplements before they go on sale. Brands make structure/function claims with a standard disclaimer, and new dietary ingredients need a notice at least 75 days before launch.
Canada reviews every product before sale. So a US-compliant label won’t work here as-is: it needs an NPN, bilingual text, the Product Facts table and claims that match a Canadian licence. Our guide to starting a supplement brand in Canada walks through the order of operations.
The bottom line
Canada’s NHP system asks more of you up front than the US does, but it’s predictable once you know the pieces. Get the product licence, confirm every site in your supply chain is licensed and GMP-ready, build labels to the 2028 standard now, and keep marketing inside your licensed claims.

Frequently asked questions
Do I need an NPN to sell supplements online in Canada?
Yes. If you sell a natural health product to people in Canada, the product needs a product licence and an NPN or DIN-HM, whether you sell through your own website, Amazon.ca or a retailer. Personal imports by consumers are handled differently, but a business selling to Canadians is expected to have the product licensed before it is offered for sale.
How long does it take to get an NPN in Canada?
Health Canada’s service standards are 60 calendar days for Class I applications, 90 for Class II and 210 for Class III. Real timelines vary. Incomplete files, unclear ingredient sourcing or claims that go beyond a monograph can lead to information requests or refusals, which add time, so a clean monograph-based application is usually the quickest route.
Can a US dietary supplement be sold in Canada as is?
Usually not. A product that is legal under DSHEA in the United States still needs a Canadian product licence, bilingual labelling, a Product Facts table and claims that match what Health Canada authorized. Some US ingredients or doses may also fall outside Canadian monographs, so reformulation or a Class III application can be needed.
Is a Canadian importer responsible for the foreign manufacturer’s quality?
Largely, yes. An importer of natural health products needs its own site licence and must hold evidence that each foreign site meets good manufacturing practices equivalent to Canada’s requirements. In practice that means audits or inspection reports, a written quality agreement, testing records and the ability to trace and recall every lot it brings into the country.
What happens if I sell an unlicensed natural health product?
Health Canada can ask you to stop sale, seize products, have listings removed and, since 2023, order recalls under its Vanessa’s Law powers. Serious or repeated violations can lead to prosecution with fines of up to $5 million. Retailers and marketplaces also commonly delist products that cannot show a valid NPN, which can hurt a young brand quickly.
Can I use customer reviews and influencers to promote my NHP?
You can, but anything you share or pay for is treated as your advertising. Reviews, reels and influencer captions must not claim more than your product licence allows, and they cannot suggest the product treats or cures serious diseases. Brief creators in writing on approved claims and review their content before it goes live.
