Many Canadians pick up a bottle of vitamins or herbal tea without ever checking whether the government has reviewed it. Natural health products are bought every day across this country, yet not everyone knows how to confirm if a product is actually approved. A natural health product license in Canada is generally required before such a product can be legally marketed with approved health claims. This guide will show you exactly how to check a product’s status in plain language, so you can shop with confidence.
What Does It Mean for a Product to Be Licensed?
A licensed product has gone through a review by Health Canada before it ever reaches the store shelf, covering its ingredients, label claims, and manufacturing practices. Once approved, it receives a unique number that proves it passed this process, managed under Health Canada’s Natural and Non-prescription Health Products Directorate.
Think of a license as a quality stamp that shows someone outside the company reviewed the formula and agreed it was reasonable. A natural label does not automatically mean a product is harmless. Plants and herbs can still interact with medications or trigger side effects, and that risk is exactly why the licensing process exists in the first place.
Understanding the Natural Product Number
The easiest way to confirm a product is licensed is to look up its NHP number on the packaging in Canada. This number is your proof that Health Canada reviewed the product before it reached the market.
Identifying the NPN Format
A Natural Product Number, or NPN, is an eight-digit code. You will usually find it printed near the bottom of the label, sometimes next to the barcode or the ingredient list. It always appears with the letters NPN directly in front of the numbers.
Once you spot it, you can write it down or take a photo so you have it ready to verify later. The format never changes from product to product, so once you know what it looks like, spotting it on any bottle becomes quick and easy.
DIN-HM for Homeopathics
If the product is a homeopathic remedy rather than a standard supplement, it will carry a DIN-HM number instead of an NPN. The format is similar, but this designation tells you the product followed the homeopathic review stream rather than the general natural health product stream.
Homeopathic medicines have their own set of evidence requirements, which differ from those for vitamins, herbal remedies, or mineral supplements. Knowing the difference between the two numbers helps you understand which type of review your product actually went through.
Locating the Number
Manufacturers are required to print this number clearly on the product label, so consumers can identify products licensed for sale in Canada by looking for the eight-digit Natural Product Number. Most brands place it near the directions for use or the list of non-medicinal ingredients, though the exact spot can vary between companies.
If you cannot locate any number at all, that is your first warning sign that something might be off with the product, and it is worth taking a closer look before you decide to buy it.
How to Use the Health Canada Database
Once you have the number from the label, confirm it in the official Health Canada product registry. This step only takes a couple of minutes and removes any guesswork.
Accessing the LNHPD Database
Health Canada keeps an online tool called the Licensed Natural Health Products Database. It is updated daily and can be searched by product name, NPN, ingredients, dosage form, license holder, or licensing date. This means you have several ways to confirm a product, even with only partial information.
The database is free to use and does not require any account or login, so anyone can search it at any time from a computer or phone. It is the same tool retailers and health practitioners rely on to confirm a product before recommending it.
Searching by Name or NPN
The fastest method is to type the NPN straight into the search field. If you do not have the number handy, searching the exact product name often works just as well, though you may need to scroll through a few similar results. Try to match the spelling on the label as closely as possible, since small differences in wording can sometimes affect what comes up in the results.
Searching by Holder or Ingredient
You can also search by the company name listed on the bottle or by a specific ingredient inside the product. This is useful when you are comparing several brands that all contain the same active ingredient and want to see which ones are properly licensed.
Searching by ingredient is also a good option when you want to research a substance before buying any product that contains it, since it shows you every licensed product currently using that ingredient.
Reading Your Search Results
Once your search returns a result, check that the product name, ingredient list, and license holder all match what is printed on your bottle. Products under review for a license are not included in the database, so an application in progress will not appear yet.
A blank result usually means the product has not been licensed, though it may also indicate that Health Canada is still processing the application. Either way, it tells you that the product has not yet earned full market authorization.
Spotting Licensed Natural Health Products
Once you know what to look for, identifying the right products becomes second nature. It is a small habit that can save you from wasted money or unwanted side effects.
Checking Products In-Store
Flip the bottle over and check for the NPN or DIN-HM before adding an item to your cart. Reputable retailers in Canada generally stock licensed products, but mistakes and gaps still happen, especially with smaller or imported brands.
Pharmacies and large grocery chains tend to be more consistent about this, while small specialty shops or farmers’ markets are worth a closer look since their stock can often change.
Verifying Online Orders
Online shopping makes this step even more important since you cannot physically inspect the packaging first. Zoom in on product photos to find the number, then confirm it through the database before you complete your order. If the listing does not include a clear photo of the label, message the seller and ask them to send one before you commit to the purchase.
When There Is No Number
If you cannot find a number anywhere, do not assume it was left off by accident. Contact the seller directly or choose a different product that clearly displays its licensing information.
There are usually plenty of licensed alternatives on the market, so you rarely need to settle for a product that cannot prove its own approval status.
Why Some Products Are Not Yet Licensed
Not every unlicensed product is dangerous, but the lack of an external safety check leaves you without one. The reasons behind a missing number can help you make a smarter decision at the shelf.
Pending Applications and Timing
Some companies have submitted their paperwork and are simply waiting for Health Canada to finish the review. This process can take months, so a brand new product on the market might genuinely be in this waiting period.
During this time, the company is not permitted to make health claims on the label, even if the product is already on store shelves.
Imported Product Differences
Products approved in another country are not automatically approved here. A supplement licensed in the United States, for example, still needs its own separate Canadian review before it can legally make health claims in this market.
This applies even to well-known international brands, since Health Canada has its own standards for ingredients, dosages, and label wording that can differ from those in other countries.
Red Flags to Watch
Be cautious of products making bold health claims with no number on the label at all, vague or missing ingredient lists, or sellers who dodge your questions about licensing. These signs usually point to a product that skipped the proper process altogether. Trust your instincts here, since a legitimate company will almost always be upfront and happy to confirm its licensing status when asked.

Quick Tips for Checking Product Licensing
A few small habits can make this whole process even easier the next time you shop.
- Check before you buy, not after. Look for the NPN or DIN-HM on the label while you are still in the store or browsing online, rather than after the product arrives.
- Save the database link. Bookmark Health Canada’s Licensed Natural Health Products Database on your phone so you can search it in seconds whenever you need to.
- Keep your receipts. If a product later turns out to be unlicensed, your receipt makes it easier to return it or report the issue.
- Watch for vague labeling. Products with no ingredient list, no dosage information, or no company contact details deserve extra caution.
- Compare similar products. If one brand has a number and a competing brand does not, that difference alone tells you a lot.
- Ask questions when in doubt. A licensed manufacturer will never hesitate to confirm its NPN or DIN-HM if you ask directly.
Conclusion
A natural health product does not need to be complicated to verify. Look for the NPN or DIN-HM on the label, confirm it through Health Canada’s official database, and trust your instincts if something seems off. This small habit protects your health and your wallet, and it puts the power back in your hands as a shopper. A valid natural health product license in Canada is something every product on the shelf should be able to prove, and now you know exactly how to check for yourself.
