Your thyroid may be small, but it plays a BIG role in metabolism, energy production, temperature regulation, growth, and many other body functions.
Here are 7 key nutrients to know for thyroid health:
IODINE-The building block
Iodine is essential for making thyroid hormones. Your thyroid uses iodine to produce T4, thyroxine, & T3, triidothyranine.Without enough iodine, thyroid hormone production can be impaired.
SELENIUM-The conversion & protection helper
Selenium is involved in enzymes called deiodenases, which help convert T4 into the more biologically active T3. It also supports antioxidant defenses that help protect thyroid tissue from oxidative stress.
VITAMIN C-The antioxidant ally
Vitamin C supports antioxidant offenses & helps protect cells from oxidative stress. It also improves non-heme iron absorption, indirectly supporting nutrients needed for normal thyroid hormone production.
VITAMIN D-The immune system supporter
Vitamin D is important for normal immune function. Because the thyroid immune systems are closely connected, adequate vitamin D status, it's an important part of overall thyroid health.
IRON-The hormone- producing helper
Iron is needed for thyroid parioxidase (TPO), an enzyme involved in thyroid hormone synthesis. Iron deficiency can therefore interfere with efficient thyroid hormone production.
ZINC-The thyroid function multi-tasker
Sync participates in numerous enzyme and protein functions involved in thyroid hormone metabolism, and cellular signaling adequate sync supports normal thyroid function and hormone activity.
TYROSINE-The amino acid building block
Tyrosine combines with iodide during thyroid hormone synthesis to form T3 and T4. Your body can make tyrosine from another amino acid, phenylalanine, but dietary protein also provides it.
THE BIG PICTURE:
Thyroid health isn't about one "magic" nutrient. It's about having adequate amounts of the right building blocks and cofactors that support hormone production, conversion, antioxidant , antioxidant protection, and normalcellular function.
Food first sources include seafood, dairy, eggs, meat, legumes, nuts, seeds, fruits, vegetables, and other nutrient dense whole foods.
