Selling supplements in Canada: NPN and the NHP framework

A supplement that sells freely in the US or EU cannot simply be shipped to Canada and sold. Canada regulates these products as Natural Health Products, and most require a licence — with a number printed on the label — before they can legally be on the market. For manufacturers used to lighter-touch regimes, Canada's pre-market system is a step up in rigour.

What an NHP is

In Canada, many supplements fall under the Natural Health Products framework, overseen by Health Canada. NHPs include vitamins and minerals, herbal products, and a range of other substances used for health purposes. The category sits in its own regulatory space — neither an unregulated food nor a pharmaceutical drug, but a defined class with its own rules.

The product licence and the NPN

The defining feature of the Canadian system is pre-market licensing. Before an NHP is sold, it generally needs a product licence from Health Canada, and once licensed it carries a Natural Product Number (NPN) — an eight-digit number that must appear on the label. The NPN is the visible sign that the product has been assessed and authorised.

This is a meaningful difference from systems where products go to market without prior authorisation. In Canada, the licence comes first.

What a licence application involves

A product licence application asks for detailed information about the product: its medicinal and non-medicinal ingredients, their amounts, the recommended use or purpose, the dose, the route of administration, the risk information, and the evidence supporting the claims and safety.

In other words, it is a structured dossier built almost entirely from precise product data — composition, doses, claims, and the evidence behind them. The quality and completeness of that data largely determines how smoothly the application goes.

Monographs make it easier

Canada's system includes monographs — pre-assessed standards for many common ingredients and product types. Formulating a product so that it fits within an applicable monograph can simplify the licensing route, because the ingredient, dose range, and permitted claims are already characterised.

This rewards formulating with the destination framework in mind: a product designed to fit a monograph is easier to license than one that strays outside it and requires more extensive supporting evidence.

Claims work differently

The claims an NHP can make are tied to the licence and the supporting evidence. A claim is not free marketing text; it is part of what is assessed and authorised, and it has to match the evidence and the product's composition. Manufacturers familiar with the EU's authorised-claims logic will recognise the principle, even though the Canadian framework is its own.

The data-quality theme, again

The thread running through Canadian market entry is the same one that runs through every regulated market: it rewards clean, structured product data. The licence application restates the composition, the doses, the claims, and the evidence. When those live in one current, structured source, assembling the application is far faster than reconstructing it from scattered files.

Because Health Canada's requirements and monographs are detailed and change over time, confirm the current rules for your specific product rather than relying on a general summary.

The takeaway

Canada treats supplements as Natural Health Products and generally requires a product licence and an NPN before sale — a genuine pre-market step built on a detailed dossier of composition, dose, claims, and evidence. Formulating to fit a monograph and keeping product data structured and current are what turn Canadian licensing from a hurdle into a manageable, repeatable process.

Lemoniq holds your composition, doses, and claims as one structured source, so the product data a Canadian licence application needs can be pulled straight from the formula — kept current as the product changes. We solve this exact problem. See how it works
