Supplement guides for Canada
The same label data and evidence as the US site, re-priced for readers in Canada: every product below is sold on Amazon.ca, priced in CAD, with cost per day worked out from the Canadian price and pack size. 93 products across 25 categories; 16 carry a Health Canada natural product number (NPN) on their listing and 10 carry an independent third-party certification (NSF, USP, Informed Sport or ConsumerLab).
How Canada differs. Health Canada licenses natural health products (the NPN on the label).
A licence is not the same thing as third-party testing, so these pages keep the two apart: the tested tier
only lists products whose certification is named by an independent program. Where a US product is not sold
on Amazon.ca, the Canadian page substitutes a Canadian-market equivalent of the same form and dose and says so.
