A product’s Natural Product Number (NPN) is an important part of its Canadian regulatory status, but it is only one step in assessing whether a product is ready for market. Supplement brands, importers, and distributors should confirm that the licence matches the product being sold and that the product’s label, claims and supply chain align with applicable Canadian requirements.
For companies preparing to launch or expand an NHP in Canada, checking an existing licence early can help uncover issues before packaging, production or distribution plans are finalized. Brands that still need to obtain a product licence should also assess their product’s classification, ingredients, proposed claims and supporting information early, since these can affect the licensing pathway, required preparation and launch timeline.
What an NPN tells you
In Canada, licensed NHPs are identified by an eight-digit NPN. Homeopathic medicines may carry a DIN-HM. Health Canada’s Licensed Natural Health Products Database (LNHPD) contains information about products that have been issued a product licence, including the product name, licence holder, ingredients, dosage form, recommended use and risk information.
An NPN is not a general certification of a brand or manufacturer. It is associated with a specific licensed product and its authorized information. A number displayed on packaging should therefore be checked against the product in the database.
How to check a product’s NPN
Use Health Canada’s Licensed Natural Health Products Database (LNHPD) to search by product name, licence holder or NPN. Compare the database record with the product and its current label.
Review whether:
- The product name and licence holder correspond to the product being sold.
- The medicinal ingredients and their amounts match the licensed details.
- The recommended use, dosage form and directions are consistent.
- The cautions, warnings and other risk information align with the licence.
- The claims on the label are consistent with the product’s authorized recommended use.
The LNHPD is updated nightly, according to Health Canada. If a product record is unclear or appears inconsistent with the packaging, resolve the discrepancy before relying on the number as evidence of the product’s status.
What the database check does not confirm
A matching database entry is a useful verification step, but it does not replace a broader compliance review. Businesses should also assess whether the product’s current label and marketing materials are appropriate, whether proposed changes may affect the licence, and whether the relevant Canadian manufacturing, packaging, labelling, importing and quality requirements have been addressed.
This matters particularly when a company is:
- Bringing an existing product into Canada.
- Changing a formula, dose, claim, product name or label.
- Using a licence held by another company.
- Preparing packaging or e-commerce content for a Canadian launch.
- Importing or distributing an NHP through a new supply chain.
- A product can appear in the database while a proposed label, website claim or business arrangement still requires review.
What supplement brands should verify before launch
Before committing to packaging or a launch date, confirm that the product’s Canadian regulatory pathway is clear and that the documentation supports the planned market presentation. Depending on the product and the work already completed, this may include reviewing classification, licence details, ingredients, claims, label text and site-licensing responsibilities.
For NHPs, timing matters. Changes to licensed information may require a regulatory action before the revised product is implemented. A review before final artwork and production can help identify questions while there is still time to address them.
Whether you are verifying an existing licence or preparing to apply for one, a clear regulatory review can help establish what your product’s Canadian market status supports and what needs to be addressed before launch.
