多種維他命和補充劑-包括碘（ 巨藻）、維他命D、硒、酪氨酸、鋅、鐵和硫胺素均有助於甲狀腺健康。
碘
碘是產生甲狀腺激素的基礎和主要原料。甲狀腺需要從飲食中攝取碘才能產生甲狀腺激素。
維他命 D
維他命 D缺乏症與橋本甲狀腺炎和甲狀腺功能低下的風險增加有關。
硒
礦物質硒有助於甲狀腺產生甲狀腺激素，將T4轉化為T3，並能降低甲狀腺過氧化物酶抗體。
酪氨酸
氨基酸酪氨酸對於甲狀腺激素的產生以及T4到T3的轉化至關重要。
鋅
礦物質鋅對於甲狀腺激素的加工、T4至T3的轉化以及支持甲狀腺功能非常重要。鋅含量低是甲狀腺功能減退症的已知誘因。
鐵
礦物質鐵對於甲狀腺和激素的健康運轉至關重要。具體而言，低鐵水平與亞臨床甲狀腺功能減退症的高風險和降低的T4和T3水平相關。
硫胺素/ 維他命 B1
硫胺素- 維他命 B1-有助於將碳水化合物代謝為能量。當水平低時，您會感到疲勞並且難以集中精力。硫胺素缺乏症在包括甲狀腺疾病在內的自身免疫性疾病患者中更為常見。
A number of vitamins and supplements — including iodine(kelp), vitamin D, selenium, probiotics, tyrosine, zinc, iron, and thiamine — can be helpful to your thyroid health.
Iodine
Iodine is a building block and primary raw material for thyroid hormone production. Your thyroid gland needs iodine from your diet in order to produce thyroid hormone.
Vitamin D
Vitamin D deficiency is linked to an increased risk of Hashimoto’s thyroiditis and to hypothyroidism.
Selenium
The mineral selenium helps your thyroid produce thyroid hormone, convert T4 into T3, and can lower thyroid peroxidase antibodies.
Tyrosine
The amino acid tyrosine is essential to the production of thyroid hormone, as well as T4 to T3 conversion.
Zinc
The mineral zinc is important for processing of thyroid hormone, T4 to T3 conversion, and in supporting thyroid function. Low levels of zinc are a known trigger for hypothyroidism.
Iron
The mineral iron is crucial to the healthy functioning of your thyroid and hormones. Specifically, low iron levels are associated with higher risk of subclinical hypothyroidism and reduced T4 and T3 levels.
Thiamine/vitamin B1
Thiamine — vitamin B1 — helps to metabolize carbohydrates into energy. When levels are low, you feel tired and have difficulty concentrating. Thiamine deficiency is more common in people with autoimmune diseases, including thyroid conditions.
