Jamieson Vitamins are made with pride in Canada. We are based in Windsor, Ontario, where the majority of our supplements are made in state-of-the art manufacturing facilities.
Some products, such as our Gummy vitamins, are manufactured by top, third-party manufacturers located globally.
All of our third-party manufacturers are personally inspected to make sure they meet Jamieson's exacting standards. Finished botanical products and botanical supply chain samples are tested using TRU-ID biotechnology, and certificates are issued for compliant samples. Click here for more information about TRU-ID.
