Hello, violetta,

 

Apparently there is an interaction between soy and thyroxine. This is evidence-based, as studies have demonstrated it. The soy decreases the effect of the thyroxine, making it necessary to take more.

Here is a link that describes the studies on this:

http://www.rotherhampct.nhs.uk/knowledgeservice/documents/Enquiries/CQAS/soyand%20thyroxine.doc

As for the interaction of thyroxine and other supplements, there's a German version of the PDR that covers drugs and their interaction with herbs. Give me a moment or so and I'll search this as well to see what I can find for you.

Hello, Violetta,

 

Here's a link from the University of Michigan outlining the effects of various herbs and showing how they could interact with drugs:

It doesn't look as though thyroxine reacts with the herbs you mentioned specifically, but still I would monitor their use carefully and listen to my own body.

I hope this has been helpful to you.

Here is another site in which a clinical study is discussed:

Apparently, gingko biloba does thin the blood and therefore must be used with great caution with NSAIDS, aspirin or drugs like coumadin or lovenox.

I will check specifically for Coq 10 and red clover and see what I can come up with.

Here is another link from University of Maryland Medical Center regarding the potential drug interactions with coq10:

http://www.umm.edu/altmed/articles/coenzyme-q10-000950.htm

Apparently, this drug may enable some people to reduce their dose of BP medication. It can also reduce the toxic effects of chemotherapy in cancer.

 

Expert:  PatriciaRN replied 6 years ago.

And here is the PDR summary of the interaction between red clover and medications:

http://www.pdrhealth.com/drugs/altmed/altmed-mono.aspx?contentFileName=ame0146.xml&contentName=Red+Clover&contentId=309

Red clover must also be used with caution with blood thinners.

I hope this has been helpful to you and good luck.
