Hi, I've recently been tested for a whole bunch of Vitamins thanks to folks advice on this great forum . . . and not my GP i'm afraid to say. My T4 is 8.8 and T3 is 4 and Vit D's 34.7 . . so low
So T4's low and T3's normal . . . so how, being on NDT do I increase T4 without also increasing T3 is one question please? Also, I've been prescribed Colecalciferol 800iu one a day, however on a couple of sites I've looked at people advocate much larger doses i.e 5000 iu plus!?
Any help would be appreciated . . . thank you for looking.
