• Phytoestrogens? at 1/12/12 3:01 PM
  • Dr. Ben,
    Can you tell me if your brand of EPO contains any phytoestrogens?
    I have a thyroid condition and phytoestrogens interfere with the hormone replacement.
    Thank you in advance!

  • Hi Linda - I will ask my customer support team to find out for you. I do not believe that phytoestrogens in normal dietary quantities mess with thyroid replacement. Look at the Japanese - how much soy they eat. Xenoestrogens are the issue. Best Dr Ben

• Phytoestrogens and Xenoestrogens at 1/12/12 11:43 PM
  • Hi Dr. Ben,
    If you do a bit more research into my previous phytoestrogen question you'll find that Soy is a true no no for thyroid patients. It's blocks hormone at the cell level. I know this from personal experience!
    Phytoestrogens do the same thing, that's why I asked the question!
    I believe GLA is the problem, after doing some more research on it.
    Thank you for looking into it for me!

  • Hi Linda - Please provide me some documentation that is well presented. I am not convinced about soy and the thyroid. Read this: http://www.ncbi.nlm.nih.gov/pubmed/21486162 If one eats a very high soy diet or high phytoestrogen diet, then I can see it affecting the thyroid. Everything in moderation. Here is a study that looked at a very high phytoestrogen diet and only 6 out of 60 converted to hypothyroidism http://www.ncbi.nlm.nih.gov/pubmed/21325465 Here is another one: http://www.ncbi.nlm.nih.gov/pubmed/16571087 I also do not treat the thyroid directly 99% of the time. I work on the adrenals and dietary changes - especially avoiding gluten. Best Dr Ben

• Soy at 1/13/12 3:22 AM
  • Hi Dr Ben,
    Here's a link to Mary Shomon's, thyroid patient advocate about.com article on Soy.
    Hashimtoto's is usually the culprit of hypothyroidism as I'm sure you know. Adrenals are a part of that, as is gluten intolerance, so I'm glad you work on those!
    Anyway, here's the article. Thank you!

  • Thank you - I'll take a look and read. To let you know, I am not a fan of soy in general. I don't like to eat it - doesn't make me feel good. Most soy is GMO as well - posing an issue - and this may be the real issue as well. For hypothyroid, I just see so many other more aggressive issues such as gluten, stress, adrenal fatigue, iodine deficiency, iron deficiency and others - soy was not at the top of my list ever but I'll consider it! Best Dr Ben
