The single most important fact in natural health product marketing in Canada is also the most overlooked: your claims are not yours to invent. They are defined by Health Canada when your product is licensed — and every word on your website has to stay inside that boundary.
Get this right and compliance and SEO pull in the same direction. Get it wrong and you risk both a regulatory complaint and a Google ranking problem at once.
What claims can you make for an NHP?
Only the claims that match your product’s authorization. When Health Canada licenses a natural health product, it issues Terms of Market Authorization (TMA) that specify the permitted uses and recommended claims. Your marketing — on the label, on the product page, in a blog post, in a meta description — must stay within those approved uses.
An NHP must carry at least one health claim, and that claim must have a genuine health context. But it cannot reach beyond what the licence allows.
The NPN: what it is and why it gates your copy
Every authorized NHP carries an NPN (Natural Product Number) — an eight-digit licence number from Health Canada (homeopathic products carry a DIN-HM). The NPN confirms the product’s approved ingredients, conditions of use, and permitted claims, and is searchable in the Licensed Natural Health Products Database.
For marketers, the NPN is not just a compliance stamp — it is the boundary of your messaging. The permitted claims attached to that licence define exactly what you can say.
Conditions of use: where your claims are actually set
If the NPN is the boundary, the Compendium of Monographs is where that boundary is drawn. For most common ingredients, Health Canada has already published a monograph that fixes the accepted conditions of use. A monograph’s conditions of use typically pin down:
- the recommended use or purpose — the health claim itself
- the dose — quantity, form and frequency
- the duration of use
- mandatory risk statements — cautions, warnings, contraindications
Every one of these is part of the authorization, and every one constrains what your marketing can say.
When you file a compendial Product Licence Application — the fast-track stream reviewed within 60 days — you attest that your product stays inside those pre-cleared conditions. That is exactly why applicants hit a wall when a condition of use isn’t allowed: if you try to claim a use, dose, population or duration the published monograph doesn’t cover, it falls outside the compendial stream. Health Canada is explicit that an application including information different from the published monograph no longer qualifies for the 60-day review.
From there your options narrow to two: bring the claim back inside the monograph, or file a non-compendial application backed by your own safety and efficacy evidence — a longer, evidence-heavy path. And if no monograph exists for your ingredient at all, the compendial route isn’t available to begin with.
For marketing, the lesson sits upstream of any copywriting: your keyword universe is decided at licensing. The permitted conditions of use become the exact language you are allowed to optimize around. A benefit that was never allowed as a condition of use can’t be rescued by a cleverly worded product page — it is a compliance gap, and on a YMYL page Google reads it as one too.
The do’s and don’ts of NHP marketing
The governing principle is simple: advertise truthfully, and never beyond the authorization.
Do:
- Use the claims consistent with your Terms of Market Authorization
- Provide accurate, substantiated information
- Keep label and web claims aligned
Don’t:
- Exceed the approved use or invent new benefits
- Make false, misleading or deceptive claims
- Imply treatment of serious diseases without authorization
- Promise guaranteed results
Claims are your keywords (the SEO angle)
Here is where regulation and SEO meet. Your permitted claims are, in practice, your keyword boundary — the language you can legitimately optimize around. Effective NHP SEO works inside those limits: it builds depth, structure and authority on approved claims rather than reaching for forbidden ones.
This matters doubly because NHP pages are classified YMYL (Your Money or Your Life) by Google and judged on strict E-E-A-T criteria. Over-claiming doesn’t just risk enforcement — it signals unreliable content to Google and erodes rankings. Compliant, well-substantiated claims do the opposite: they satisfy Health Canada and Google at once.
Where brands get flagged
The most common failure isn’t the label — it’s the gap between the label and the website. A page that adds benefits the licence never granted, a meta description that overstates an effect, an alt tag that implies a cure: each is a claim, and each must match the authorization. Audit your web claims against your TMA, not just your packaging.

Frequently Asked Questions
What claims can you make for a natural health product in Canada?
Only claims that match the product's Health Canada authorization. Every NHP is licensed with specific permitted uses (its Terms of Market Authorization), and your marketing claims — on the label and on every web page — must stay within those approved uses. Claims that exceed them, or that are false or misleading, are prohibited.
What is an NPN and why does it matter for marketing?
An NPN (Natural Product Number) is the eight-digit licence Health Canada assigns to an authorized NHP. It confirms the product's approved ingredients, uses and claims. For marketing, the NPN is the boundary of your copy: the permitted claims attached to that licence define what you can legally say.
Can you advertise natural health products to consumers in Canada?
Yes. Unlike prescription drugs, NHPs can be advertised directly to consumers — but only within their authorization. Claims must be truthful, not misleading, and consistent with the product's Terms of Market Authorization. Going beyond the approved use turns a marketing message into a compliance violation.
What kinds of NHP claims are not allowed?
Claims that exceed the authorized use, that are false, misleading or deceptive, that promise to treat serious diseases without authorization, or that imply guaranteed results. Comparative or disease-treatment claims beyond the licence are a common source of enforcement and of Google YMYL credibility problems.
How do NHP claims affect SEO?
Your permitted claims are effectively your keyword boundary: they define the language you can optimize around. Strong NHP SEO ranks within those limits while satisfying Google's YMYL and E-E-A-T standards. Over-claiming both risks regulatory action and signals unreliable content to Google.
Where do the permitted conditions of use for an NHP come from?
For most common ingredients, from Health Canada's Compendium of Monographs. Each monograph sets the accepted conditions of use — recommended use or purpose, dose, duration and required risk statements. A compendial Product Licence Application must stay inside those pre-cleared conditions. If your ingredient has no published monograph, you must submit your own safety and efficacy evidence instead.
What does it mean when a condition of use is not allowed for an NHP?
It means the use, dose, population or duration you are trying to claim falls outside the published monograph. Health Canada is explicit that an application differing from the monograph no longer qualifies for the 60-day compendial review. Your options are to bring the claim back inside the monograph, or file a non-compendial application backed by your own evidence — a longer path. A condition that was never authorized can't be added later through marketing copy.
