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.
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.
