Ingredients & Sourcing

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 offers a variety of products that are gelatin-free; you can find our list here.

You can find out list of gluten-free products here. However, please note that many of our products are sourced from raw materials that naturally contain gluten (wheat, barley, etc.) Therefore, depending on the severity of your allergy, it may be important to note that we are not a gluten free facility. As always, remember to consult with your health care practitioner before starting any new supplement routine and carefully read all product labels.

As a brand, Jamieson products are not formulated overall specifically for vegans. We do offer a few select items as well as many vegetarian products. Additionally, our vegetarian logo can be found on the front label of all applicable products, and you can view a list here. As always, remember to consult with your health care practitioner before starting any new supplement routine.

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.

The “No Animal Testing” shown as a rabbit on our labels represents our commitment that we do not test any of our supplements on animals. In fact, when choosing our suppliers, part of the selection process is to make sure that the companies in question meet our high standards of quality, including cruelty-free business practices. Our suppliers are regularly assessed, and if any concern were to arise, it would be addressed immediately.

The majority of our vitamins and supplements are made in our state-of-the-art laboratories in Windsor, Ontario. Some products, such as our probiotic supplements for products in gummy formats, are manufactured by top third-party manufacturers for the specific delivery form. These qualified third-party manufacturers are fully GMP certified and have been personally inspected to ensure that they meet Jamieson's exacting standards.

Packaging & Sustainability

Our goal is always to use the minimum amount of packaging required, helping to reduce waste. Since we are producing natural health products, there are industry-wide standards we comply with to ensure that all necessary information is communicated on our packaging, in a font large enough for all to read. We try our best to use the smallest product footprint possible, while still printing labels with text that is easily legible. Please also note that all of our packaging is recyclable and should be recycled when empty.

Taking Your Vitamins

In general, many of your vitamins can be taken together. However, always check the label directions to ensure there are no specific interactions.

One such example is calcium and iron, which should not be taken together (as calcium inhibits iron absorption). Also check the label directions to see if any of your vitamins need to be taken with food or on an empty stomach – in which case you may need to take them separately.

In terms of medications, while some supplements actually assist in making up for nutrients that can be depleted while taking prescription drugs (statin drugs taken with CoQ10, for example), your doctor can guide you on what to take when to ensure maximum safety and absorption.

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).

You can check out our "What Should I Take" feature here. To ensure that these products are appropriate for you or for more specific concerns, it is important for you to consult your trusted health care practitioner. Please note that this feature is not intended as a substitute for advice from your health care practitioner, or any information contained on or in any product label or packaging.

While all Jamieson products are shelf-stable, you should always consult the individual product label for storage conditions for each product. For instance, it is advised to refrigerate some of our probiotics after opening to ensure maximum potency and freshness.

It all depends on the vitamin or natural health product you are taking. Some products are best taken on an empty stomach, while others should be taken with food (usually to help increase absorption or prevent stomach upset from occurring).

If a product is meant to be taken with food, this will always be indicated in the directions on the product label. If there is no specific mention, you can take it whichever way you prefer.

It is best to take your vitamins with a glass of water rather than a cup of coffee.

The issue with coffee is that it works as a stimulant and helps speed the passage of materials through your digestive tract. This means you won’t necessarily absorb all of the nutrients in your vitamins as you would if they moved more slowly through your system.

Coffee can also cause excessive urination, speeding the removal of water-soluble vitamins from your system. Try to finish your coffee at least 15-20 minutes before taking your vitamins; otherwise it is best to take your vitamins a few hours after finishing your coffee.

Our recommendation would be not to exceed the recommended daily dose advised on the product label.

For example, if you are supposed to take one multivitamin daily and you miss your dose, it isn't best to take two the next day. If, however, you typically take two tablets per day in divided doses (e.g. vitamin C 500 mg taken twice daily) and you miss taking your morning tablet, you could take two in the evening.

Please remember that you should not double up if it would cause you to exceed the recommended daily dose.

Yes, all vitamins are effective regardless of their format.

Jamieson tests products within its laboratories to ensure they can be easily broken down and absorbed by your body.

Powders and chewables will be absorbed faster than tablets (because they are already partially broken down before you take them), but this doesn’t change their effectiveness.

Jamieson offers a variety of formats to suit consumer needs and preferences, so simply choose the one you like most.
