How to Read a Natural Health Product Label in Canada
Short answer: every licensed natural health product (NHP) sold in Canada carries an eight-digit NPN (or DIN-HM for homeopathic medicines), its medicinal ingredients with the amount in each dose, a list of non-medicinal ingredients, its recommended use, dose and (where one applies) duration of use, risk information, storage conditions, and a lot number and expiry date. The required information must appear in English and French. Read those parts in that order and you will know what the product is, whether Health Canada licensed it, and how to use it safely.
The parts of an NHP label at a glance
| Label element | What it tells you | What to check |
|---|---|---|
| NPN or DIN-HM (8 digits) | Health Canada has licensed the product for sale in Canada | Look the number up in the Licensed Natural Health Products Database (LNHPD) |
| Medicinal ingredients | The ingredients that do the work, by proper name, with the quantity per dosage unit (for example per capsule or per mL) | Compare the amount per dose, not per bottle. Extracts may also show potency, an extract ratio or a crude-herb equivalent |
| Source material | What each medicinal ingredient comes from (for example a plant part or fish oil) | Allergies and diet: animal, fish, shellfish or plant sources |
| Non-medicinal ingredients | Fillers, capsule shell, flavours, colours and preservatives (listed by name, without amounts) | Allergens, gelatin, sugar alcohols, dyes |
| Recommended use or purpose | The health claim Health Canada authorized for this product | Does the authorized use match why you are buying it? |
| Dose and directions | Who it is for, how much, how often, and how to take it | Age group, maximum daily amount, with or without food |
| Duration of use (if any) | How long to use it before stopping or asking a health professional | Plan to check in with a pharmacist or doctor at that point |
| Risk information | Cautions and warnings, contraindications (when not to use it) and known adverse reactions | Pregnancy, breastfeeding, medicines you take, health conditions |
| Storage | How to keep the product so it stays stable | Heat, light, refrigeration after opening |
| Lot number and expiry date | Which batch you have, and the date (at least year and month) after which it should not be used | Do not use after expiry; keep the lot number if you report a problem |
1. Start with the NPN
The product number is the fastest way to tell a licensed product from an unlicensed one. A licensed NHP shows "NPN" followed by eight digits; a homeopathic medicine shows "DIN-HM". Non-prescription drugs, such as many pain relievers and antihistamines, carry a DIN instead and follow drug labelling rules (including a Drug Facts table), not NHP rules. To confirm the number matches the product in your hand, follow our step-by-step guide: How to Check an NPN or DIN on Health Canada's Database.
2. Medicinal vs non-medicinal ingredients
Medicinal ingredients are the active parts of the product: vitamins, minerals, herbs, probiotics, amino acids and similar substances. Each one is listed by its proper name with the quantity in one dosage unit. For herbal extracts the label may add the potency (for example a standardized marker compound) or an extract ratio, so two products with the same "mg" can contain different amounts of the herb.
Non-medicinal ingredients are everything else: the capsule shell, binders, flow agents such as magnesium stearate or silica, flavours and colours. They are listed without amounts. This is the section to read if you avoid gelatin, have a food allergy, or want to know about added sweeteners.
3. Recommended use, dose and duration
Health Canada defines a product's recommended conditions of use as its use or purpose, dosage form, route of administration, dose, duration of use and risk information. They are reviewed as part of the product licence. Two practical tips:
- Check the age group in the dose. Many adult products are not labelled for children.
- If a duration is listed (for example, a note to consult a health care practitioner for use beyond a set number of weeks), treat it as a check-in point, not a suggestion to stop reading the label.
4. Risk information
Risk information is grouped as cautions and warnings, contraindications and known adverse reactions. On newer labels it sits under "Warnings" in the Product Facts table. Read it before your first dose, and again if you start a new medicine, become pregnant or are diagnosed with a new condition. If anything in it applies to you, ask a pharmacist before using the product.
5. Lot number and expiry date
The lot number identifies the manufacturing batch. Health Canada's labelling guidance recommends that it be preceded by "Lot", "Lot No." or "(L)". The expiry date must be shown at least as a year and month. If you ever report a side effect or a quality problem, the lot number lets the company and Health Canada trace the batch, so keep the package until the product is finished.
Old labels vs the new Product Facts table
Health Canada amended the labelling rules so that NHPs carry a standardized Product Facts table, similar in idea to the Nutrition Facts table on food. It groups the medicinal ingredients, uses, warnings, directions, other information such as storage, the non-medicinal ingredients, and a contact for questions. Products licensed before June 21, 2025 have a transition period to June 2028, so you will see both the older layout and the new table on shelves for some time. Health Canada has also announced that it plans to propose more flexible labelling rules with a further transition period, so check its compliance bulletin for the latest dates.
Quick checklist before you buy
- NPN or DIN-HM present, and it matches the LNHPD record
- Medicinal ingredient amounts compared per dose, not per bottle
- Non-medicinal ingredients checked for allergens
- Recommended use matches your reason for buying
- Dose fits your age group; duration noted
- Warnings read; pharmacist asked if any apply
- Expiry date far enough away for the bottle size
When to talk to a pharmacist or doctor
Ask a pharmacist before using an NHP if you are pregnant or breastfeeding, take prescription medicines, have a chronic condition, are buying for a child, or plan to use more than the labelled dose or for longer than the labelled duration. Stop and get medical advice if you notice a reaction listed in the risk information. You can report side effects to Health Canada through MedEffect Canada.
Shop with the label in mind: every product page on Healthy Hub lists the ingredients and directions from the Canadian label.
