This has been asked and answered, but I cannot understand as it seems to vary, for some vitamin D lowers TSH and for some dont. I have googled around and found some research stating that vitamin D lowers TSH in AIT as it lowers antibodies, some studies states its only in Graves. And in some studies its related to age that young people with optima vitamin D status have low TSH and in some studies it affects only male. I simply cannot understand it all Being tired and trying to read medical stuff in foreign language is hard.
How about t4 and t3?
If some lovely person could give me simple answer. Like ve-ry simp-le, its dummy here reading Dummy as I am so tired.
