I just tried Bob's Red Mill Paleo flour blend.  It is gluten free and also lower carb.  I made the blueberry muffins on the back and they were the best I've found!  The outside is crispy and the inside is tender, soft! 

I read an article by Suzie Cohen, America's Most Trusted Pharmacist, about biotin helping the thyroid and also helping MS patients grow some myelin.  You must read the whole article before trying this.  I am discovering that all of my health issues stem from intestinal problems of celiac.  Biotin is supposed to be produced there if all is working like it should.
