Every one of the natural supplements we offer was selected according to stringent quality control criteria. They have to meet, and even surpass, the norms established by Health Canada for natural health products and must conform to the best established pharmacopeia system such as the United States pharmacopoeia (USP), the European Pharmacopeia (EDQM), the Japanese pharmacopoeia or the German Commision E. All supplements must be both highly effective as well as very safe. These criteria apply to all supplements we offer, vitamins, minerals, proteins and herbal formulas.
