You need to stop supplementing ferritin immediately as you risk iron overload. You need to get an iron panel test done as your level of ferritin is too high and this will contribute to you feeling ill.

You should also stop supplementing folate.

Vitamin D what dose are you taking?

What thyroid supplements are you taking and dose?



TSH is low-normal, FT4 and FT3 are low in range. I've suggested before this may due to secondary hypothyroidism.

B12 is optimal around 1,000. I would supplement 1,000mcg methylcobalamin and take a B Complex vitamin. Folate is fine over range as long as B12 isn't deficient.

How much vitamin D are you supplementing? 75.2 is replete (75-200) so you could stop supplementing until October if you are able to get some sun on your face and arms a few hours per week.

Ferritin is over range. This is probably due to you supplementing but can also be due to infection or inflammation in the body. I would stop supplementing iron and retest in 4-6 months.

so do i have secondary hypothyroydism then....i will try the b12. vitamin d is prescribed by doctor to avoid osteosporsis. it doesnt say the mgs or whatever but i take two a day. adcal-d3 and calcium carbonate..the b12 should help my breathing

thanks very much



i am virtually housebound because of breathing and rapid heartbeat on standing so i dont get any sunshine



Keep taking the vitamin D prescribed if you are housebound. I hope the B12 helps your breathing.



i not need to to do anything about my t4 and t3



I think your GP should consider secondary hypothyroidism and refer you to endocrinology for management but it is possible your GP won't see there is any problem unless, and until, FT4 is below range. You could show GP the NICE CKS recommendation re secondary hypothyroidism.



is ft4 below range from thyroids knowledgable point of view but not docs. read the link and as i have adrenal failure as well as pituarity probs you would think he would at least investigate it. not sure where to go from here. i have taken b complex in the past but just from asda. never taken b12. is any form of these okor some better than others
