Suze, misschien heb je hier iets aan?
Richard Shames, MD met Mary Shomon, die van het boek *: This particular vitamin is so crucial to thyroid function that its status has now been elevated by researchers to co-hormone. We now know that the variability of thyroid to work or not work in your body is dependent upon the presence of Vitamin D, making it not just of benefit, but absolutely essential.
Thyroid treatment isn't optimal -- and may not work -- if you do not have adequate Vitamin D for the crucial final metabolic step, which takes place at the site where thyroid hormone actually works. This happens inside the nucleus of the cell. Vitamin D needs to be present at sufficient levels in the cell in order for the thyroid hormone to actually affect that cell. That is why vitamin D is so crucial.
I believe that a blood test for Vitamin D is essential for anyone dealing with hypothyroidism. The typical normal range for Vitamin D levels is from around 30 to 100. Keep in mind in mind that just being in the low end of normal range will not do an adequate job for someone with an underactive thyroid person. Thyroid patients need to be "replete" -- and that means alevel of at least 50 - 60 level, or greater. (dit zijn Amerikaanse waarden, voor omrekenen ongeveer x 2 doen)
Vitamin D and autoimmune thyroid diseases

Abstract
The role of vitamin D as an immune modulator has been emphasized in recent years, and low levels of the hormone were observed in several autoimmune diseases including multiple sclerosis and systemic lupus erythematosus. Vitamin D mediates its effect though binding to vitamin D receptor (VDR), and activation of VDR-responsive genes. While VDR gene polymorphism was found to associate with autoimmune thyroid diseases (AITDs), few studies examined levels of vitamin D in these patients and those that did yielded conflicting results.
We therefore undertook to evaluate the levels of vitamin D in patients with AITDs compared to patients with non-AITDs and healthy controls. Serum vitamin D (25-OH) levels were measured in 50 patients with AITDs, 42 patients with non-AITDs and 98 healthy subjects, utilizing the LIAISON chemiluminescence immunoassay (DiaSorin, Saluggia, Italy). Vitamin D deficiency was designated at levels lower than 10 ng/ml. Antithyroid antibodies, thyroid functions and demographic parameters were evaluated in all patients.
The prevalence of vitamin D deficiency was significantly higher in patients with AITDs compared with healthy individuals (72% versus 30.6%; P<0.001), as well as in patients with Hashimoto's thyroiditis compared to patients with non-AITDs (79% versus 52%; P<0.05). Vitamin D deficiency also correlated to the presence of antithyroid antibodies (P=0.01) and abnormal thyroid function tests (P=0.059). Significantly low levels of vitamin D were documented in patients with AITDs that were related to the presence of anti thyroid antibodies and abnormal thyroid function tests, suggesting the involvement of vitamin D in the pathogenesis of AITDs and the advisability of supplementation.
