Getting an NPN for a women’s health supplement is a key step before your product can be sold in Canada. Every natural health product (NHP) on the Canadian market needs a Natural Product Number. Health Canada’s Natural and Non-prescription Health Products Directorate (NNHPD) reviews each application against the Natural Health Products Regulations.
Women’s health supplements often carry claims related to menopause, menstrual health, or prenatal nutrition. The way you choose ingredients, select monographs, and word your claims shapes how your application is classified and how long it takes to review. A well-prepared application moves through review more smoothly than one assembled late in product development.
In this guide, we walk through how to get an NPN for a women’s health supplement. We cover which licences apply, how application classes work, what evidence Health Canada expects, and where companies most often run into delays.
What Is an NPN and Why Does Your Product Need One?
A Natural Product Number is an eight-digit number Health Canada issues once it has assessed a natural health product for safety, efficacy, and quality. The NPN appears on the product label and confirms that the product is licensed for sale in Canada. If you’re new to the system, our overview of what an NPN is and why it matters in Canada covers the fundamentals.
For women’s health supplements, this includes products for menopause support, menstrual health, prenatal nutrition, bone health, and similar uses. Products sold online, in retail stores, or through practitioners all need an NPN before they can be sold. The requirement applies regardless of company size or sales channel.
Understanding the Regulatory Framework
Health Canada regulates natural health products under the Natural Health Products Regulations (SOR/2003-196). These regulations define what qualifies as an NHP, set out the licensing requirements, and specify what evidence manufacturers must provide. Women’s health supplements fall squarely within this framework.
The type of licence you need depends on your role. If you are the company placing the product on the market, you need a product licence. If you are manufacturing, packaging, labelling, or importing the product, you also need a site licence. Both licences are administered by the NNHPD and require separate applications.
Preparing Your NPN Application
Health Canada requires you to complete your product licence application using its web-based PLA form and submit it electronically through Canada Post’s Connect service. Before you begin, gather all the components the directorate will review. A complete application includes the product name, dosage form, route of administration, recommended use or purpose, medicinal ingredients with quantities, non-medicinal ingredients, and supporting evidence for all health claims.
For women’s health products specifically, the evidence standard matters enormously. Health Canada accepts its own monographs, published in the Compendium of Monographs, as pre-assessed sources. When your ingredients and claims align with a recognized compendial monograph, the review time is typically shorter. Non-compendial claims require you to submit supporting evidence such as clinical studies or systematic reviews, which adds complexity to your dossier.
Health Canada’s official guidance on preparing and submitting your product licence application outlines the exact format and content requirements. Reviewing this document before you build your submission will save you considerable time.
Specific Considerations for Women’s Health Claims
Women’s health supplements often carry claims that Health Canada scrutinizes carefully. Statements about menstrual cycle support, perimenopause symptoms, hormone regulation, or fertility are considered therapeutic claims and require substantiated evidence. Lower-risk claims face a lower evidentiary bar, but they must still be worded precisely to stay within approved language.
Ingredient selection is equally important. Many women’s health formulations include botanicals such as black cohosh, chaste tree berry, or evening primrose oil. Each medicinal ingredient must appear in the NHPID as a permitted ingredient, and an ingredient that isn’t listed requires a new ingredient submission first. If your formulation uses an ingredient ratio or combination not covered by an existing monograph, you will need to submit your own supporting evidence.
Label Requirements to Address Early
Your product label must satisfy the requirements set out under the Natural Health Products Regulations. Required elements include the NPN (once issued), the recommended dose, any risk information, cautions and warnings, and storage conditions. For women’s health products, specific cautions apply to ingredients that are contraindicated during pregnancy or breastfeeding. Addressing these requirements during the formulation stage, rather than after submission, prevents label-driven information requests that delay your approval.
Review Timelines and What to Expect
Health Canada’s service standards are 60 days for Class I applications, which attest to a single monograph, and 90 days for Class II applications. Class III applications, which include evidence beyond existing monographs, follow a 30-day screening period and a 180-day full assessment. Since June 2025, Health Canada has also screened Class II applications by prioritization criteria, and applicants must submit a Workload Management Form within seven calendar days of their acknowledgement letter. If Health Canada issues an Information Request Notice (IRN), a complete and timely response keeps your application moving, which is why submission quality matters so much upfront.

Common Mistakes That Delay Approval
Several patterns consistently lead to information requests and refused applications. The first is mismatched claim language, where the recommended use on the label does not align with the evidence submitted. The second is incomplete medicinal ingredient details, particularly when manufacturers omit the plant part, extraction ratio, or standardized marker compounds. The third is submitting non-compendial evidence in a format that does not meet Health Canada’s dossier standards.
A fourth common issue involves missing or vague cautions and risk information. Health Canada expects specific language for certain ingredients, and generalized safety statements are rarely sufficient. Reviewing licensed products with similar ingredients in the Licensed Natural Health Products Database (LNHPD) before finalizing your label is a practical way to align with expectations.
Frequently Asked Questions
Can I sell a women's health supplement in Canada without an NPN while my application is under review?
This is a common assumption, but it is incorrect. Health Canada does not permit the sale of unlicensed natural health products during the review period. Selling without an NPN exposes your company to enforcement action, including product seizure and compliance orders. Once your NPN is issued, you may begin commercial sale. The timeline can feel long, but submitting a well-prepared application is the most reliable way to reach that milestone quickly.
Does Health Canada require clinical trials for women's health supplement claims?
Not necessarily, though the evidence standard depends on the type of claim you are making. Many women's health ingredients are covered by Health Canada monographs, which allows you to rely on compendial references rather than new clinical data. However, novel ingredients or claims outside existing monographs do require supporting evidence such as randomized controlled trials or systematic reviews. Understanding whether your formulation falls within or outside compendial coverage early in your development process will shape how you build your dossier.
What happens if Health Canada issues an Information Request Notice on my application?
An Information Request Notice can feel discouraging, but it is a standard part of the review process and does not signal an automatic rejection. Health Canada issues one when your submission is missing information or requires clarification. You have a set period to respond, as stated in the notice. A strong, thorough response that directly addresses each point gives your application the best chance of moving to approval. Partnering with a regulatory expert to draft your response reduces the risk of compounding the original issue.
