Canadian Quality
Understanding Canadian Natural Health Products
A plain-language guide to product licences, NPNs, site requirements, labels and the evidence behind authorized uses.
Natural health products in Canada are regulated by Health Canada. The framework covers products such as many vitamins, minerals, herbal remedies, probiotics and traditional medicines, with requirements that extend from evidence and labels to manufacturing sites and post-market responsibilities.
What an NPN means
An authorized natural health product is assigned an eight-digit Natural Product Number, or NPN. It appears on the label and identifies a specific product licence rather than a company-wide approval.
Health Canada reviews information supporting safety, efficacy and quality under the proposed conditions of use. Consumers should still follow the authorized label, including dose, duration, risk statements and storage directions.
Products and sites have different roles
A product licence concerns the formula, recommended use and label. Site licensing applies to activities such as manufacturing, packaging, labelling and importing, with evidence of Good Manufacturing Practices.
These responsibilities work together. A sound formula cannot compensate for uncontrolled manufacturing, and a well-run facility cannot authorize unsupported claims on its own.
How to verify before purchase
Look for the NPN and compare the product name, medicinal ingredients and directions with the current label. Health Canada's public databases can help consumers review authorized product information.
Be cautious when a website uses certification language without a product number, current certificate or clear scope. A logo is not a substitute for traceable documentation.
Key Takeaways
An NPN is an eight-digit, product-specific licence number.
Product licensing and site licensing serve different purposes.
The authorized label defines how the product should be used.
