In Canada, understanding supplement labeling requirements is essential for businesses that manufacture, import, or sell natural health products (NHPs). Additionally, Canadian labels must provide clear information about the product, its ingredients, recommended use, safety information, and regulatory authorization.
However, compliant labeling involves more than listing ingredients and adding a product name. Requirements can also cover product identification, bilingual information, traceability, warnings, and the presentation of required details.

Therefore, businesses should compare the final label with the product’s authorized information before manufacturing or distributing packaging.
What Are the Main Supplement Labeling Requirements in Canada?
In Canada, many products commonly described as supplements fall under Canada’s Natural Health Products framework. As a result, labeling requirements help consumers understand what these products contain, how they should be used, and what precautions may apply.
In particular, key labeling areas include:
| Labeling Area | Main Information |
|---|---|
| Product identification | Product name, dosage form, product number |
| Ingredients | Medicinal and non-medicinal ingredients |
| Recommended use | Purpose, dose, route of administration |
| Safety | Warnings, cautions, contraindications |
| Traceability | Lot number and expiry date |
| Business information | Licence holder or importer information |
| Storage | Applicable storage conditions |
| Language | Required information in English and French |
Required information must also remain clear and accessible to consumers. Furthermore, additional requirements may apply depending on the product.
As a result, businesses should treat the label as part of the product’s regulatory documentation rather than simply a marketing asset.

What Product Information Must Appear on a Supplement Label?
The principal display panel helps identify an NHP and can contain information such as the product name, dosage form, product number, and quantity.
A complete label may also include:
- Product or brand name
- Dosage form
- NPN or DIN-HM, where applicable
- Product quantity
- Medicinal ingredients
- Non-medicinal ingredients
- Recommended use
- Dose and route of administration
- Warnings and other risk information
- Lot number
- Expiry date
- Storage conditions
- Licence holder or importer information
More importantly, the product number connects the product with its Canadian regulatory authorization. Authorized natural health products generally carry an eight-digit Natural Product Number (NPN), while applicable homeopathic medicines may carry a DIN-HM.
In addition, labels must remain readable. Similarly, font size, contrast, spacing, and placement can all affect how easily consumers access required information.
How Should Ingredients Be Listed on Supplement Labels?
Importantly, ingredient disclosure is a central part of Canadian NHP labeling. In particular, the label distinguishes between medicinal and non-medicinal ingredients.
For example, medicinal ingredient information can include the ingredient name, quantity per dosage unit, potency, and source material where applicable. Non-medicinal ingredients must also be listed when required.
| Ingredient Type | Information |
|---|---|
| Medicinal ingredients | Name, quantity, potency where applicable |
| Source material | Source associated with medicinal ingredients where required |
| Non-medicinal ingredients | Applicable ingredient names |
| Allergens | Relevant information where applicable |
| Gluten | Applicable information where required |
| Sulphites | Added sulphites where applicable |
Importantly, the ingredient information should accurately represent the authorized formulation. Therefore, businesses should compare the final label with the product specifications and regulatory documentation before printing.
What Information Is Required for Recommended Use and Warnings?
More specifically, recommended use and safety information explain how an NHP should be used and what precautions may apply.
For example, depending on the product, the label can include:
- Recommended use or purpose
- Route of administration
- Recommended dose
- Duration of use
- Warnings
- Cautions
- Contraindications
- Known adverse reactions
- Allergen information
- Storage conditions
In addition, safety statements should correspond with the product’s authorized information. For example, businesses should not remove or modify an important warning simply to make the label shorter or more visually appealing.
Similarly, adding broad statements such as “safe for everyone” can create problems if they do not accurately represent the product’s authorized safety information.
Therefore, businesses should review significant changes to warnings, contraindications, and other risk information before using them on updated packaging.
Where Should Licensing Information Appear on the Label?
More importantly, licensing information connects the physical product with its Canadian regulatory authorization.
In particular, for an NHP, the product number is an important identifier. For example, depending on the product, this may be an NPN or DIN-HM.
Additionally, other information can identify the responsible licence holder or importer and provide applicable contact details.
| Information | Purpose |
|---|---|
| NPN or DIN-HM | Identifies the applicable product authorization |
| Licence holder | Identifies the responsible party |
| Importer information | Identifies the applicable importing business |
| Contact information | Provides a way to contact the responsible party |
| Lot number | Supports batch traceability |
| Expiry date | Identifies the applicable expiry |
The exact placement can vary according to the label structure and product type. However, businesses should ensure that licensing information matches the current regulatory documentation.
It is also important to distinguish regulatory information from laboratory documentation. An NPN identifies product authorization, while a Certificate of Analysis provides analytical information about a tested product or batch.

What Labeling Mistakes Can Create Compliance Issues?
Labeling problems often occur when businesses treat compliance as a purely graphic design task. As a result, even small differences between the authorized product information and the final label can create issues.
For example, common labeling issues include:
| Potential Issue | Why It Matters |
|---|---|
| Missing product number | Product identification may be incomplete |
| Incorrect ingredient quantity | Label may not match the authorized formulation |
| Missing warnings | Required safety information may be absent |
| Incorrect dosage | Consumers may receive inaccurate directions |
| Missing lot number | Batch traceability may be affected |
| Missing expiry date | Product information may be incomplete |
| Unsupported claims | Marketing statements may conflict with authorized information |
| Incomplete bilingual information | Language requirements may not be met |
| Poor readability | Required information may be difficult to access |
Canadian requirements also prohibit labeling that is false, misleading, deceptive, or likely to create an erroneous impression about characteristics such as composition, merit, or safety.
Furthermore, Canada’s NHP labeling framework is undergoing changes. The 2022 labeling amendments came into force on June 21, 2025, while the current compliance date for the updated requirements is June 21, 2028.
Consequently, companies preparing new packaging should consider the current requirements and transition timeline rather than relying on older label templates.

No. Instead, a Certificate of Analysis provides laboratory information about a tested product or batch. It does not replace the labeling requirements that apply to an NHP.
Can businesses change warnings on an existing label?
Changes to warnings and other risk information can have regulatory implications. Therefore, businesses should review the applicable requirements before changing authorized safety information.
Conclusion
Overall, supplement labeling requirements in Canada cover product identification, ingredients, recommended use, safety information, licensing details, traceability, and other applicable information.
Therefore, businesses should develop labels around the product’s authorized information instead of treating labeling as the final stage of graphic design.
