Unlike most manufacturers who rely on external facilities to develop and manufacture their supplements, Jamieson Laboratories develops, creates and manufactures its formulations at our own laboratory in Windsor, Ontario.Jamieson is a pioneer in advanced healthcare products and provides consumers with innovative proprietary formulations — the first mega-potency-level vitamins, the first DIN-approved botanical medicines and the first clinically proven over-the-counter nutritional antioxidant to reduce cholesterol, to name a few.

Jamieson offers a comprehensive range of products in the following categories:
• vitamin and mineral supplements
• nutritional food supplements
• standardized herbal extracts and botanical medicines
• vitamin-enriched skincare
• diet and digestive formulations.
Jamieson’s extensive line of more than 225 products features our group of unique proprietary formulas, combining premium natural-source raw materials in state-of-the-art formulations that promote optimal wellness and support vitality, heart and bone health, digestion, weight management and skincare.
