Hi, I'm hypo and on 100mg levo and 3 x 20 mg lio a day.
I have read that being low / deficient in folate, ferritin, vit D, vit B12 and/or iron affects absorption of thyroid meds. As I'm on levo, I believe that I should be in the top quarter of the range for these.
My iron was not tested - GP told me it was the same as ferritin!!!!
I have very low ferritin 29.9 ( 10 - 204 ), low B12 617 ( 187 - 883 ). What affect will this have on my thyroid test results? I don't understand what it means by "isn't absorbed properly". I understand that I will not be getting the full benefit of levo and lio but does this affect the T4, T3, FT4, FT3 or TSH level blood tests?
Also, I was diagnosed vit D deficient three years ago and prescribed 2 x 400 iu tabs a day. I find that is not sufficient when there is little or no sun - my problem is that I can't store vit. D. I take more depending on the weather.
When I was diagnosed my result was 10 in a range of 12 to something. My latest test result is different. It was 84 in a range of over 75. I was told that makes it normal.
As a hypo sufferer is 84 sufficient or should I be taking more vit D?
I'd be really grateful for any help any one can give me.
Thanks in advance.
