Frequently Asked Questions
Ingredients & Sourcing
Do you offer gelatin-free products ?
Jamieson offers a variety of products that are gelatin-free; you can find our list here.
DO YOU OFFER GLUTEN-FREE PRODUCTS ?
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.
ARE ANY OF YOUR PRODUCTS VEGETARIAN / VEGAN ?
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.
ARE ALL OF YOUR PRODUCTS NATURAL ?
Jamieson ensures natural sourced raw materials are utilized where ever possible. 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.
DOES JAMIESON TEST ON ANIMALS ?
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.
WHERE ARE YOUR PRODUCTS MANUFACTURED?
The majority of our vitamins and supplements are made in our state-of-the-art laboratories in Windsor, Ontario. Some products, such as our 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.
can i take all of my vitamins together, or even with my other medications ?
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.
WHEN SHOULD i BE TAKING MY VITAMINS ?
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).
HOW DO I KNOW WHICH SUPPLEMENTS TO TAKE ?
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.
should i be taking my vitamins on an empty or full stomach ?
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.
CAN I TAKE MY VITAMINS WITH MY MORNING COFFEE ?
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.
if I forget to take my vitamins, should i just double up and take them when i remember ?
Jamieson’s 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.
can i take too much vitamins ?
Getting too much of any nutrient can be dangerous. Taking more than you need of any vitamin or mineral may be bad for your health and can even be toxic. It is best to follow the directions stated on the product and do to exceed the recommended dose unless advised to do so by a physician for a particular reason.
IS IT NORMAL FOR URINE TO BE BRIGHT YELLOW AFTER TAKING A MULTI-VITAMIN ?
Certain vitamins such as vitamin C or vitamin B2 (riboflavin) may cause a change in the color of urine and it is not the result of any damage to the body or detrimental effect. The excess of these water soluble vitamins are flushed from your body on a daily basis and are not stored. There is no need for concern or reason to stop using the vitamin if the colour change is due to the vitamin alone. If you suspect there may be any additional reason you should consult your doctor.
What is TRU-ID CERTIFICATION ?
TRU-ID is a Canadian, independent DNA certification program. It utilizes the latest in DNA technology to trace the active ingredients in herbal supplements right back to their specific botanical origins, thus certifying their authenticity. As an early adopter of this cutting-edge certification program, Jamieson is helping lead the way to better industry standards and reinforcing trust in the Jamieson brand.
