Health Canada is advising Canadians about unauthorized health products that may pose serious health risks. Health Canada finds unauthorized health products that are promoted for sexual enhancement, weight loss, as a workout aid, or as “poppers,” and that are labelled to contain or have been tested and found to contain dangerous ingredients. Unauthorized health products have not been approved by Health Canada, which means that they have not been assessed for safety, effectiveness and quality. Unauthorized health products can pose many health dangers.
