23. Helps Against Thyroid Problems

Vitamin D deficiency has been found to exacerbate symptoms of autoimmune thyroid disease, particularly that of Graves’ disease and Hashimoto’s thyroiditis. Low levels of vitamin D have been found to speed up the onset of Grave’s disease, and has been noted to influence the increase in size of the thyroid gland.
Supplementing patients with vitamin D has been found to decrease the symptoms associated with Graves’ disease and has been suggested to be able to reverse its progression.
