Vitamin D is a fat-soluble vitamin that is key to maintaining bone health, absorbing calcium and phosphorus, and regulating the immune system. It is primarily produced in the skin when exposed to sunlight, but can also be obtained from foods such as fatty fish (salmon, tuna, sardines), egg yolks, and foods fortified with vitamin D.

Benefits : Vitamin D plays many vital roles:

• Bone and dental health : essential for the absorption of calcium and phosphorus, which are necessary for healthy bones and teeth.

• Immune system support : regulates immune response and may help alleviate inflammatory diseases, including autoimmune diseases such as Hashimoto's.

• Hormone regulation : contributes to maintaining the body's hormonal balance.

• Anti-inflammatory effect : reduces inflammation, which is especially important in autoimmune diseases such as Hashimoto's.

Thyroid and Vitamin D

Thyroid diseases, especially Hashimoto's, are often associated with low vitamin D levels. Supplementing with vitamin D is also particularly important because vitamin D regulates immune system function and can help reduce autoimmune processes. Studies have shown that normalizing vitamin D levels can improve thyroid function and relieve Hashimoto's symptoms.

Link to inflammation and hypothyroidism

Vitamin D deficiency can contribute to inflammation, which can be especially harmful in cases of thyroid problems. Adequate levels of vitamin D can help reduce inflammation in the body, thereby alleviating symptoms of hypothyroidism, such as fatigue, depression, and a slowed metabolism.

Natural sources : fatty fish (salmon, mackerel, herring, sardines), cod liver oil, egg yolk, liver, as well as dairy products and cereals fortified with vitamin D.
