Your thyroid function depends on how much iron you have. If you have low iron levels then your thyroid function may be compromised.

This is especially important for people who have thyroid disease because they are very sensitive to even small changes in iron levels.

And doctors are not conditioned to look at iron stores unless they find that you are anemic. But it is possible to be iron deficient even if you are not anemic and this deficiency CAN impact your thyroid negatively.

Thyroid function and iron are linked in the following ways:
– Low iron reduces the amount of thyroid hormone that your body can produce directly from your thyroid gland.
– Low iron is associated with decreased T4 to T3 conversion.
– Low iron is associated with low T3.
– Low iron reduces the effectiveness of iodine supplementation.
– As transferrin falls, your TSH rises.

Testing for iron deficiency is actually quite easy and I recommend that all thyroid patients should consider testing for iron deficiency with the following lab tests:
– Ferritin: Should be between 40 and 50
– TIBC: Should be in the middle of the reference range
– Serum iron: Should be in the middle of the reference range
– Percent saturation: Should be between 35 to 38%

If these values are confusing then you can primarily stick just to ferritin. You don’t necessarily need to order all of those other tests because ferritin is usually a good enough predictor of iron stores.

If you find that you are deficient then you can supplement with iron using over the counter formulations. Most thyroid patients do better on liquid iron or very specific iron capsules.

  1. Why is ferritin optimal specifically between 40-50? The reference range on the my lab results is 16-235. From what I’ve read 40-50 seems a little low for women.

    • Hi Jrb,

      At high levels, ferritin is a measure of iron storage or inflammation. Iron is toxic at high levels as is inflammation. You want to optimize your ferritin to the minimum level necessary to see results without going over it or else you’ll cause more harm than good.

  2. Dear Dr. Childs

    The reciprocal relationship between thyroid hormone status and iron status is such an important point. The not uncommon coexistence of iron deficiency anaemia & HT/hypo can be a vicious cycle, especially in pre-menopausal women, due to thyroid hormone’s role in regulating menstruation.

    Your site is unique that you don’t shy away from providing biochemical details and scientific references.

    – Low iron reduces the amount of thyroid hormone that your body can produce directly from your thyroid gland.
    >> This is obvious, as TPO and DUOX2 are heme-iron dependent enzymes for thyroid hormone biogenesis.
    >> The following “associations” are less clear. It would be great if you could provide reference links or source of info, such as observations from your own patients.
    – Low iron is associated with decreased T4 to T3 conversion.
    – Low iron is associated with low T3.
    – Low iron reduces the effectiveness of iodine supplementation.
    – As transferrin falls, your TSH rises.

    Thankyou for your awesome work

    • Hi URGreat,

      Great questions! The original article that you are referencing here was written by me many years ago so I honestly don’t remember the sources off of the top of my head. I can tell you based on knowing myself and how I think that I wouldn’t have included those statements unless I read them in some source, I just don’t know which one. Please check out the original article which may have links to references: https://www.restartmed.com/hypothyroidism-iron-deficiency/

      I am currently making my way through my older posts and updating them with newer information/studies so I will eventually get to that one but I don’t have an ETA on when that will happen. Right now there’s so much to write about and not enough time in the day to hit everything I’d like.
