Unfortunately I forgot about the early am/empty stomach rule for blood test and did mine about 2pm, after lunch (brainfog!!).
I have a large number of the symptoms listed for underactive thyroid by thyroid.org and have been convinced for several years that is my problem but my GP refuses to look at anything but TSH despite the fact that I feel dreadful most of the time.
Of all results, both private and NHS over the last year or so, the only consistent problem showing has been Vitamin D, ranging from 50-74 so I have decided to take a supplement.
My question is how much to take. I have Solgar D3, 1000iu (25ug) - could anyone please tell me how much I should be taking ? Dosage on bottle says one mealtime.
I intend to have another blood test in about a month from BH to include Vit D this time.
Thanks in advance for your time.
