How Do I Know I'm Actually Getting the Ingredients You Say You're Putting In Your Swanson Supplements?

Friday, November 15, 2013 by Vitamins and Supplements FAQs
Question: How do I know that I'm actually getting the ingredients you say you're putting in the supplements?


This question cuts to the core of our family-owned, customer-focused business here at Swanson Health Products. It is by no means the first time we've been asked this, and we usually get questions like this whenever the news cycle spins around to another "investigation" into the efficacy or safety of dietary supplements. It usually happens about twice a year. 

We're very fortunate to...

What is Coenzyme Q10 Derived From?

Tuesday, June 25, 2013 by Vitamins and Supplements FAQs

Question: What is Coenzyme Q10 derived from? I have read the label ingredients but want to know about the coenzyme itself. If it's from animal, what kind. I'm considering taking this product but always want to know what I'm taking.
Thanks, Dean

Well this is an easy one! Our CoQ10 (coenzyme Q10) is an all-natural trans isomer derived from yeast fermentation.


Follow-up Question: You don't say if this is Ubiquinol or Ubiquinone? As we know, the former is clearly the best, as it does not require...

Why Do Some Swanson Products Contain Rice Flour?

Thursday, December 6, 2012 by Vitamins and Supplements FAQs

Question: I would like to know why so many Swansons products have rice flour in the (other ingrediants) label. Within the last couple of months Consumers Reports Magizine had an article on rice containing arsenic. I have not been able to take Swanson products due to being allergic to rice.


Contrary to what Consumer Reports might have you believe, not all supplement manufacturers are the same or take the same precautions when it comes to safety and quality. Our manufacturers are all required to...

What Is Michio Kushi’s Fermented Superfood Complex?

Wednesday, October 10, 2012 by Vitamins and Supplements FAQs

Question: Could you please tell me what category Michio Kushi’s Fermented Superfood Complex is in? It is touted as a whole food product but does it have vitamin or mineral nutritional values, and if so how does it compare to a whole food vitamin product? If it does compare to a whole food vitamin why are the vitamin and mineral values not listed?

What is Calcium Pyruvate?

Tuesday, October 2, 2012 by Vitamins and Supplements FAQs

Question: Thank you for the very informative article on the best form of calcium supplement. I do not see any information, though, on Calcium PYRUVATE, which I take. Can you please explain the difference between it and the other forms of calcium you mention?

Calcium pyruvate is just one of several forms of calcium, as you've pointed out. Unfortunately with all these forms, it’s kind of like asking how Vitamin C is different depending on what form it comes in... does it come from an orange, an...

Does Swanson Have Fish Oil, Krill Oil and Borage Oil in One Capsule?

Wednesday, September 26, 2012 by Vitamins and Supplements FAQs

Multi-Omega 3-6-9Question: I just read your answer regarding the Krill Oil, on line. Does Swanson have all three oils in one capsule (Fish, Krill and Borage oils)? Or, anything close to it? My OB/GYN doctor recommended to take DHA as a prenatal supplement. I have been taking EFA from QNR. But, I would love to try all three oils in one.


We’ve never seen Krill Oil with Fish and Borage Oil in the same pill and it is a bit redundant to take Fish Oil and Krill Oiltogether, as they share the most important nutrients...

Friday, September 21, 2012 by Vitamins and Supplements FAQs

Question: Is 5 htp relationship to tryptophan similar to ubiquinol's relationship to CO Q10? Also what is the best form of Calcium- so many forms. Is citrate really the best and why? If not, please explain how all the forms are derived and what their strengths and weak points are.

Should Calcium Supplements Be Taken Alone?

Wednesday, September 19, 2012 by Vitamins and Supplements FAQs

Question: I have read that calcium supplements can interact with other supplements and so should be taken alone. Is that true? And does one form of calcium interact more than another? If so, which form can be taken with other supplements? For many years I had taken BoneUp but switched to Swanson Coral Calcium Complex a couple of years ago.


Calcium can compete for absorption with other minerals such as iron, zinc and copper which are normally taken in smaller amounts.  Calcium should be taken...
