Frequently asked questions

Can I take all my vitamins at once?

It's generally best to space out certain vitamins and minerals to maximize absorption. For example, avoid taking calcium and iron together. Consult a healthcare provider for personalized advice.

Why should some vitamins be taken with food?

Fat-soluble vitamins like A, D, E, and K require dietary fat for absorption, so taking them with food helps ensure they are effectively absorbed.

Is it okay to take supplements on an empty stomach?

Some supplements, like probiotics and iron, are often recommended on an empty stomach for better absorption, but this can vary based on individual tolerance.

How can I tell if a supplement is approved in Canada?

Look for a Natural Product Number (NPN) on the label, which indicates the product has been reviewed and approved by Health Canada for safety and efficacy.

Should I consult a healthcare professional before taking supplements?

Yes, it's advisable to consult with a healthcare provider to ensure supplements are appropriate for your health needs and to avoid potential interactions with medications.

For general information only and not medical advice. In Canada, natural health products should carry an NPN (Natural Product Number) or DIN-HM. Talk to a healthcare professional or pharmacist before starting a supplement, especially if pregnant, nursing, taking medication or managing a health condition.
