While estrogen is not inherently harmful to us with thyroid disease, it can change our thyroid hormone dose requirement, so that's an important note to keep in mind. (When I talked with Dr. Langer, I mentioned EPO and he said he was telling people to take borage oil now. Borage is basically in the same family and does the same things as well.)>> Thanks for good info as usual Mary. :-) (BTW, how's the pregnancy coming along? Hope you're doing great!) But one question, does borage oil also increase the amount of estrogen a person has? I just attended a talk by a man who says excess estrogen is the cause of all sorts of problems, including thyroid dysfunction. He basically is against adding any more sources of estrogen to anyone's intake and feels the amount we already do receive needs to be balanced by increased natural progesterone to get to optimum health. Interesting, but I'm still weighing whether I should believe all this or not. (My skepticism arose because he was selling his own products to help the problems he discussed.) Take care, Cindy
