Vitamin D3 may reduce thyroid damage
Supplementation with active vitamin D3 ameliorates experimental autoimmune thyroiditis in mice by modulating the differentiation and functionality of intrathyroidal T-cell subsets.
Most Relevant Research
We explored the potential benefits of vitamin D3 in treating autoimmune thyroiditis, specifically focusing on Hashimoto's thyroiditis. In a controlled experiment, female NOD/ShiLtJ mice were subjected to a treatment regimen that included a specific dosage of vitamin D3 injected every other day for eight weeks.

Our observations revealed that vitamin D3 significantly reduced thyroid damage caused by the autoimmune response. Mice receiving this treatment showed a decrease in thyroid inflammation, with lower levels of thyroid autoantibodies in their serum. Additionally, vitamin D3 appeared to reverse the changes in immune cell profiles in the thyroid.

Specifically, the treatment helped inhibit the overactive pro-inflammatory T-cell subsets while promoting the function of anti-inflammatory cells. This modulation within the immune system suggests that vitamin D3 supplementation may serve as an effective approach to manage the symptoms and progression of Hashimoto's thyroiditis.

Strong immunity boost
Most Useful Review
Taking one capsule a day significantly improves my immunity against various viral diseases. Over the years, my family, including children, has not experienced any major cold or illness. As someone with Hashimoto's thyroiditis, this supplement is essential for me due to its link with vitamin D deficiency.

Zinc's link to Hashimoto's thyroiditis
Association Between Essential Trace Elements and Thyroid Antibodies in the Blood of Women with Newly Diagnosed Hashimoto's Thyroiditis.
Most Relevant Research
We explored the connection between essential trace elements, particularly zinc, and Hashimoto’s thyroiditis (HT) in women who were newly diagnosed. In this study, we looked at a group of 56 women with HT and compared them to 64 matched controls.

The results showed that women with HT had significantly lower levels of selenium, iron, and zinc in their blood compared to the controls. Interestingly, their copper levels were higher. We examined the relationships between these trace elements and thyroid autoantibodies, which can indicate the presence of autoimmune activity affecting the thyroid.

While we noted a significant correlation between lower zinc (and other elements) and higher levels of thyroid antibodies, the study did not specifically focus on zinc treatment. This means that while zinc levels appear to be linked to autoantibody levels in HT, we can't definitively state that zinc treatment will improve the condition without further dedicated research.

Overall, the study indicates that lower zinc levels in conjunction with selenium and iron deficiencies might be involved in the autoimmune response seen in Hashimoto’s thyroiditis. Thus, this provides an avenue for future exploration into zinc's role as a potential supplement for women diagnosed with this condition.

Reduced symptoms
Most Useful Review
Excellent! Zinc and selenium are crucial for my Hashimoto's treatment. Initially, I experienced symptoms like abdominal discomfort and gas. After incorporating these supplements, my situation improved, especially after I stopped consuming milk, which I later realised was affecting my absorption. Now, I feel much better.
