How to Get an NPN in Canada: A Step-by-Step Guide for Manufacturers

Why You Need an NPN

If you want to sell a natural health product (NHP) in Canada — vitamins, minerals, herbal remedies, probiotics, or traditional medicines — you must have a Natural Product Number (NPN) issued by Health Canada. It's not optional. It's the law under the Natural Health Products Regulations (NHPR).

Without an NPN, your product cannot legally be sold, imported, advertised, or distributed anywhere in Canada. Retailers won't carry it. Amazon won't list it. Dropshippers won't touch it.

What Is an NPN?

An NPN is an eight-digit number that Health Canada assigns to a natural health product after reviewing its safety, efficacy, and quality. It tells consumers and retailers that the product has been assessed and meets Canadian standards.

Think of it as a product licence — similar to a DIN (Drug Identification Number) for pharmaceuticals, but specifically for natural health products.

The 5 Steps to Getting Your NPN

Step 1: Identify the Correct Monograph

Health Canada maintains a database of over 800 monographs — pre-approved ingredient profiles that define the allowed dose ranges, route of administration, target populations, and permitted health claims for each substance.

Monograph fit, proposed conditions of use, and the evidence package influence the application pathway. A formula should be assessed as a whole before a class or timeline is assumed.

Pro tip: Most delays come from mismatching ingredients to monographs. The NNHPD Single Ingredient Monograph database is your best friend here.

Step 2: Prepare Your Product Licence Application (PLA)

The PLA is the core submission to Health Canada. It includes:

Product name (brand name + proper name)
Medicinal ingredients with exact quantities per dosage unit
Non-medicinal ingredients (excipients, capsule materials, preservatives)
Recommended dosage (must fall within monograph ranges)
Route of administration (oral, topical, etc.)
Recommended use or purpose (the health claim — must match monograph language)
Risk information (contraindications, warnings, adverse reactions)
Specifications for each medicinal ingredient (identity, purity, potency)

Step 3: Create Your Product Facts Table

By 2028, Health Canada is transitioning natural health products to a standardized NHP Product Facts Table on labels — similar to the Nutrition Facts table on food. It must include:

Medicinal ingredients with quantity per unit
Non-medicinal ingredients list
Recommended dose
Risk information
Lot number and expiry date

If you're working with Nostrum Health, we generate this automatically as part of your application.

Step 4: Submit Through the Health Canada Portal

You submit your PLA through Health Canada's submission process. Pathway and review timing depend on the formulation, claims, evidence, application quality, and Health Canada's current review process; published service standards are not approval guarantees.

Step 5: Receive Your NPN (or Fix Deficiencies)

If everything is in order, Health Canada issues your NPN and you're legally cleared to sell. If there are deficiencies, they'll send a request for clarification — this is where most applicants lose weeks or months responding to detailed questions about their formulation.

Common Mistakes That Delay NPN Approval

Wrong monograph match — Selecting a monograph that doesn't exactly match your ingredient form or dose
Dosage outside monograph range — Your recommended dose must fall within the monograph's minimum and maximum
Missing risk information — Every contraindication and warning in the monograph must appear on your label
Incomplete specifications — Identity, purity, and potency testing must meet NNHPD standards
Incorrect Product Facts Table format — Must follow the exact template prescribed by Health Canada
