Supplements are everywhere, and the choice can be confusing. This guide does not say what you should take; it covers how to read a label and shop with care.
If you have a medical condition or take medication, speak to a pharmacist or doctor before starting any supplement.
Reading the label
In Canada, licensed natural health products carry an eight-digit Natural Product Number (NPN) or a DIN-HM on the label. It is worth checking that one is present.
- NPN or DIN-HM on the label
- The amount of the active ingredient per capsule, not just per bottle
- Number of capsules and servings per bottle, to work out the cost per serving
- Allergen and gluten information, if relevant to you
Comparing like with like
Two bottles of the same ingredient can differ in the form used and the dose per capsule, so compare the label, not the front of the bottle.
