Jamieson Quality — Trusted by Canadians Since 1922


Jamieson Laboratories, Canada’s oldest and largest manufacturer and distributor of natural vitamins, minerals, concentrated food supplements, herbs and botanical medicines celebrates its 90th anniversary this year from a position of strength, market leadership earned by consistently providing innovative products of the highest quality, purity and safety.

Competing in a market that is far more international in nature than it was back in 1922 when Jamieson first established operations, the Company continues to attract new customers while retaining its existing clientele because its vitamins and natural supplements earn their trust each and every day.



At the core of this confidence are Jamieson’s state-of-the-art pharmaceutical manufacturing laboratories in Windsor, Ontario, and the formulation and manufacture of products through its exclusive 360 Pure protocols. This initiative integrates a minimum of 360 scientific controls, calibrated bioassays and clinical procedures that are all part of the Good Manufacturing Practice (GMP) approval from Health Canada. Jamieson is a certified pharmaceutical GMP company and is regularly audited by Health Canada.


Throughout its history, Jamieson has been a pioneer in the natural healthcare market, providing consumers with innovative products like the first mega-potency level vitamins, the first DIN approved botanical medicines and the first clinically-proven OTC nutritional antioxidant to reduce cholesterol.


Just as it has since 1922, Jamieson will continue to adhere to the hallmarks of its trusted brand — quality, purity and safety.
