Jamieson Vitamin D3 Extra Strength

Jamieson counts as one of Canada's oldest and most iconic health supplement brands, founded originally in 1922 in Windsor, Ontario. The brand has built a reputation over more than a century for producing high-quality vitamins, minerals, and plant-based supplements.

The manufacturing for Jamieson products primarily takes place in its state-of-the-art facilities located in Windsor, Ontario, Canada. These facilities adhere to strict '360 Pure' quality control protocols ensuring that ingredients are tested for potency and purity throughout the production process.

Historically a family-led Canadian enterprise founded by C.E. Jamieson, the company went public and was eventually acquired by Jamieson Wellness Inc. (formerly known as Jamieson Laboratories Ltd.). While it remains a Canadian-based company with headquarters in Toronto and manufacturing in Windsor, it is now part of a global health wellness network, having been acquired by the major private equity firm CCMP Capital but currently operating as a publicly traded entity on the Toronto Stock Exchange (TSX: JZ). In certain global markets, specifically China and other Asian territories, local distribution and equity partnerships help manage the brand's expansive international footprint.
