Vitamin D Improves Thyroid Autoimmunity

More good news regarding vitamin D supplementation and thyroid autoimmunity. Another study has shown supplementation can improve thyroid autoimmunity, this time in women with already normal vitamin D levels. Let’s discuss.

Vitamin D Improves Thyroid Autoimmunity

Dr. Michael Ruscio: Vitamin D helps decrease thyroid autoimmunity—more good news!

Hi, this is Dr. Ruscio. And you may have remembered several months ago we discussed a landmark study.

To my knowledge, it was the first of its kind that showed that supplementation with vitamin D could lower thyroid autoimmunity, which was very exciting because we’ve seen a lot of correlation data showing that people with certain autoimmune conditions also have low vitamin D, but not nearly as much data showing that supplementing with vitamin D can actually improve autoimmune conditions.

So the study that we discussed a while back was very exciting in that regard. Now, thankfully, another follow-up study has shown similar results.

And I’ll put the abstract up here on the screen. And I’ll quote for you. The title of the study was “The Effect of Vitamin D on Thyroid Autoimmunity in Levothyroxine-Treated Women with Hashimoto’s Thyroiditis and Normal Vitamin D Status.” (1a)

So a couple things that we can pull away just from the title is that this was treating women who had hypothyroidism and were on Levothyroxine therapy and—and this is maybe even more important—they also had normal vitamin D levels. So they were above 20.

And so even for women with normal—and again, what we call normal is somewhat debatable—but generally normal levels of vitamin D still benefited from some additional vitamin D supplementation with regards to their thyroid autoimmunity.

Vitamin D reduced the thyroid peroxidase antibodies and the thyroglobulin antibodies, two of the more common antibodies that are tested to assess the activity of thyroid autoimmunity. The greater effect was in the TPO antibodies.

And I’ll read the conclusion here. “Vitamin D preparations may reduce thyroid autoimmunity in Levothyroxine-treated women with Hashimoto’s thyroiditis and normal vitamin D status.”

So very exciting, because what this means is you could simply take a maintenance dose of maybe 2, 4, or 6000 IUs of vitamin D a day, even if you have normal vitamin D levels, and see a positive impact on your thyroid autoimmunity.

You do want to be careful not to over-supplement with vitamin D, because levels that are too high can also be problematic. But certainly, a lower, maintenance-type dose of around 2-ish-thousand IUs a day is very reasonable and may help with thyroid autoimmunity.

I’ll also link to the review of the previous study on vitamin D aiding with thyroid autoimmunity, where they showed a 20% reduction in TPO antibodies after supplementing with vitamin D. (2a)

So what’s really nice about this study and the nice piece that it adds to the whole picture is that even in women with normal or semi-normal vitamin D, additional supplementation of vitamin D can help benefit thyroid autoimmunity.

Now, there are many things that fit into the mosaic of managing thyroid autoimmunity. Vitamin D is one. Selenium is another that may be helpful. And the health of one’s gut can also be incredibly important, so don’t forget about that.

I guess that’s it. If you’re struggling with thyroid autoimmunity, then vitamin D may be a nice option to help quell that process.

This is Dr. Ruscio. And I hope this information helps you get healthy and get back to your life. Thanks!

  1. Hi Dr Ruscio

    How are things with you? So i have been trying to do a biofilm protocol for the past 2 weeks and have been rotating BioFilm Defense, Candex and Candisol enzymes & also including Serrapeptase. The recommended dosage is 2 caps am/ 2 caps PM. The problem is even 1/2 a cap daily feels like its causing upper GI distress (i.e. minor reflux, burping) for me. The concentration of enzymes is pretty high so i feel it may be irritating my upper GI mucosa but I also read these enzymes are “antimuscarinic” and can relax the LES muscle on the esophagus.

    So i am taking a break for a few days but I feel I need to definitely address the biofilms if i am to successfully treat my parasites and Candida. Do you have any recommendations? I was considering using DGL, marshmallow root in combo with the enzymes but i read its not good to use these since they can protect the organisms and creat additional layers of mucus. Any thoughts would be very much appreciated. Thank you so much!

    1. Hi Kelli,
      I can’t provide personal health advise here. That being said, even if I could there is just way to much I dont know to be able to offer anything other than saying experiment with different agents until you find ones that are well tolerated. That, can sometimes be all that is needed, so it’s worth considering.
      Hope this helps.

      1. your other posts look like medical advice to me – plus i am just asking for general suggestions . not really sure why you even post responses on here to peoples questions if you cant offer any insight

  3. Dr. Ruscio,

    Thank you for the great review of this Vit D study. Do you have any recommendations on how to supplement with D? Do you suggest people always supplement in combination with K2?

    Thanks for sharing your insights,

    1. Hi Nicole,
      I usually recommend a conservative dose for those deficient; 2,000-8,000 IU/day. Those those who have normal levels and AI I may recommend 2,000-4,000 IUs/day. I like to see D at least at 30, ideally 40-50 but I don’t obsess over it.
