Jamieson ensures natural sourced raw materials are utilized where ever possible. This means that in order to produce a safe and effective product, there are many factors that are taken into consideration to developing a product. Sometimes natural ingredients are not stable or able to extract sufficient levels of active ingredients to deliver an efficacious raw material. This is when Jamieson utilizes synthetic items to ensure that we are delivering effective products to Canadians. Please be assured that all ingredients used in Jamieson products have been reviewed and approved by Health Canada to ensure their safety and efficacy.
