What vitamins support thyroid function?
What vitamins support thyroid function?
The thyroid gland plays a crucial role in regulating metabolism, and certain vitamins and minerals are essential for its proper function. Here are the key vitamins that support thyroid health:
Vitamin D:
Vitamin D is important for immune function and thyroid health. Low levels of vitamin D have been associated with autoimmune thyroid conditions such as Hashimoto’s thyroiditis and Graves’ disease. Ensuring adequate vitamin D levels through sun exposure, diet, or supplements can support overall thyroid function and help reduce the risk of autoimmune thyroid disorders (Holick, 2007).
Vitamin A:
Vitamin A supports thyroid hormone production and the conversion of thyroxine (T4) to the more active triiodothyronine (T3). Adequate vitamin A levels are important for maintaining thyroid function and regulating metabolism. Foods rich in vitamin A include carrots, sweet potatoes, and leafy greens, or supplementation can be considered if dietary intake is insufficient (Penniston & Tanumihardjo, 2006).
Vitamin B12:
Vitamin B12 is essential for energy production and neurological function. A deficiency in B12 can exacerbate symptoms of hypothyroidism, such as fatigue and depression. Since hypothyroidism can impair B12 absorption, individuals with thyroid issues should ensure they get enough B12 through diet or supplements (Smith & Refsum, 2016).
Selenium:
While not a vitamin, selenium is a crucial mineral for thyroid health. It plays a key role in the conversion of T4 to T3 and protects the thyroid gland from oxidative damage. Selenium deficiency has been linked to thyroid dysfunction, including Hashimoto’s thyroiditis. Brazil nuts, seafood, and selenium supplements are good sources of this essential mineral (Rayman, 2012).
Zinc:
Zinc is another important mineral for thyroid function, supporting the production of thyroid hormones and the regulation of the immune system. Zinc deficiency can impair thyroid function and lead to symptoms such as hair loss and weakened immunity. Zinc-rich foods include oysters, beef, and pumpkin seeds, or supplements can be used to ensure adequate intake (Prasad, 2008).
Conclusion:
Vitamins and minerals such as vitamin D, vitamin A, vitamin B12, selenium, and zinc are essential for supporting thyroid function. These nutrients help regulate thyroid hormone production, protect against oxidative stress, and support overall metabolic health. Ensuring adequate intake through diet or supplements can help maintain healthy thyroid function.
