Frequently asked questions
Does “superfood” have a standard legal definition?
No. It is a marketing term, so compare the actual ingredients and nutrition information.
Are greens powders a replacement for vegetables?
They should not be assumed to replace varied whole foods.
Do all items in this collection have an NPN?
No. Conventional foods use food labels, while licensed NHPs generally carry an NPN or DIN-HM.
How do I compare two Healthy Foods, Greens & Superfoods products?
Compare the exact medicinal ingredients, amount per full daily serving, dosage form, Canadian licence number when applicable, intended use, warnings and total daily cost. A longer ingredient list or higher number on the front label does not by itself make a product more suitable.[2][4]
Is a higher dose or more ingredients always better?
No. The useful amount depends on the nutrient or ingredient, the reason for use, food intake, age, health conditions and medicines. Higher exposure can add adverse effects, interactions or duplicate ingredients without adding benefit.[3][4]
Can I combine several products from this collection?
Sometimes, but compare every medicinal ingredient first. Multivitamins, powders, herbs and condition-specific formulas often overlap. A pharmacist can total the daily exposure and check whether the combination conflicts with medicines or health conditions.[3][2]
How quickly should I expect a supplement to work?
The answer depends on the ingredient, the outcome being measured and whether a deficiency or other cause is present. Agree on a realistic outcome and review date before starting; do not continue an ineffective product indefinitely or delay assessment of persistent symptoms.[3]
Can natural health products interact with prescription medicines?
Yes. Natural health products can alter absorption, sedation, bleeding, blood pressure, blood glucose, thyroid tests and drug metabolism. Share the product name, NPN or DIN-HM, ingredient list and dose with your pharmacist or prescriber.[3][2]
How do I verify a product sold in Canada?
Licensed natural health products normally display an eight-digit NPN or DIN-HM. Search that number in Health Canada’s database and compare the licensed use, ingredients, dose and risk statements with the package in hand. Cosmetics, foods and accessories follow different rules.[1][2]
Who should obtain individualized advice before choosing a product?
Ask first if you are pregnant or breastfeeding, selecting a product for a child, preparing for surgery, taking prescription medicines, or living with kidney, liver, heart, bleeding, immune, seizure or hormone-sensitive conditions. Bring an up-to-date medication and supplement list.[3]
