Vitamin D’s main role is to regulate bone metabolism and calcium and phosphorus levels in the body, so it is not surprising if you generally associate vitamin D with keeping your bones strong and healthy. Over the past several years, though, other vitamin D roles have been examined, including its role in heart disease, cancer, and
autoimmune conditions, like Hashimoto’s and Graves’ disease. Let’s delve a bit deeper into the basics of vitamin D, and what a deficiency in this vitamin may mean for your thyroid health.
Research has found a link between Vitamin D deficiency and autoimmune thyroid diseases (AITD), which are Hashimoto’s thyroiditis and Graves’ disease. For example, one study found that the presence of vitamin D deficiency was significantly higher in patients with autoimmune thyroid disease, as compared to healthy patients
(72 percent versus 31 percent, respectively).Other research has found an association between vitamin D deficiency and the presence of anti-thyroid antibodies, hinting that vitamin D deficiency may be a trigger for the development of autoimmune thyroid disease.
Lastly, early research suggests that vitamin D supplementation may help manage thyroid disease. For instance, one study demonstrated that antibodies in autoimmune thyroid disease significantly decreased as a result of taking vitamin D at 1,000 IU per day for one month.
The bottom line here is that vitamin D may play a role in a person’s thyroid health, but whether or not there is a direct link between vitamin D deficiency and the development or progression of autoimmune thyroid disease remains unknown.
