In 2004, Canada began regulating natural medicines as a category of products separate from foods or drugs. These products are officially recognized as "Natural Health Products." These products include vitamins, minerals, herbal preparations, homeopathic products, probiotics, fatty acids, amino acids, and other naturally derived supplements.
In order to be marketed in Canada, natural health products must be licensed. In order to be licensed in Canada, manufacturers must submit applications to Health Canada including information about uses, formulation, dosing, safety, and efficacy.
Products can be licensed based on several criteria. Some products are licensed based on historical or traditional uses. For example, if an herbal product has a history of traditional use, then that product may be acceptable for licensure. In this case, no reliable scientific evidence is required for approval.
For products with non-traditional uses, some level of scientific evidence may be required to support claimed uses. However, a high level of evidence is not necessarily required. Acceptable sources of evidence include at least one well-designed, randomized, controlled trial; well-designed, non-randomized trials; cohort and case control studies; or expert opinion reports.
Finished products licensed by Health Canada must be manufactured according to Good Manufacturing Practices (GMPs) as outlined by Health Canada.
