Frequently Asked Question!

Jamieson Vitamin D is derived from the world’s finest lanolin, an abundant, rich and renewable source of Vitamin D. The lanolin is extracted from the sun-drenched wool of sheep living in the high country of Australia and New Zealand and then shipped to France, where it undergoes sophisticated, state-of-the-art processing to yield an exceptionally pure, crystalline form of pre-Vitamin D3. Exposure to ultraviolet light — the same mechanism that allows the body to naturally synthesize Vitamin D — activates the pre-Vitamin D and converts it to a pharmaceutical-grade Vitamin D3.


Whenever possible, we have made the switch to the most natural available (with the ability to be formulated) types of sweeteners to ensure that our flavoured products are delicious. For example, fourteen of our formulas are now sweetened with stevia. To find out if a product is sweetened, or with what sweetener, you can search for the individual product of interest, and then click “Ingredient Information”.


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.


Jamieson NEVER TESTS on animals or uses third-party manufacturers that do. We are dedicated to the health and wellness of people and the planet, and animals are an important part of that commitment.

In general, the best time to take your vitamins is whenever it is most convenient for you and when you are most likely to be consistent with the routine. However, it is important that you read and follow the label for directions of use, as some products are specifically meant to have an effect at a certain time of day (e.g. melatonin should be taken at bedtime to improve sleep).
