On 1 January 2004, Health Canada officially added a new term to the global list of synonyms for dietary supplements: natural health products (NHP). Developed with the intent of providing Canadian consumers with ready access to NHP that are safe, effective, and of high quality, the Natural Health Products Regulations (the NHP regulations) are applicable to the sale, manufacture, packaging, labelling, importation, distribution, and storage of NHP, and are administered by the recently formed Natural Health Products Directorate (NHPD) within Health Canada. This paper provides an overview of the process for regulating supplement products in Canada.
