Best Thyroid Supplement: 11 Natural Ingredients

1. Iodine

Iodine is probably the best supplement out there because it helps in creating hormones. It can be found in milk, cheese, poultry, seaweed, and iodized salt.
Iodine makes up most of T3 and T4, the two primary hormones that the thyroid gland produces. Without it, metabolic conditions like hypothyroidism may occur.
Other than eating iodine-rich foods, there are two primary iodine supplements: One is a salt called potassium iodide and one by way of chelated iodine.
Potassium iodide should be taken with caution, as the body has the tendency to absorb it rapidly. Make sure you don’t take too much of it, and always consult with your doctor to find out what daily amount works best.
Chelated iodine comes from seaweed-based foods like kelp. Unlike potassium iodide, it takes much longer for the body to absorb it. This ensures a steady iodine release for your thyroid to use.
Note: Taking iodine supplements with high blood pressure medication and/or diuretics may increase the risk of high blood potassium.
What Is T3? T3 is triiodothyronine, a thyroid hormone that affects development, growth, body temperature, and metabolism. It is the active form of thyroxine.
What Is T4? T4 is thyroxine, the main hormone that the thyroid gland produces and secretes into the bloodstream.

2. Vitamin B12

This is another thyroid supplement that is also conveniently water-soluble. Vitamin B12 is crucial in assisting with cell metabolism, as well as nerve cell function, and reducing the dreaded brain fog.
Studies show that vitamin B12 deficiency is common in those suffering from hypothyroidism. This is due to hypothyroidism impairing your body’s ability to effectively absorb vitamin B12.
While increasing your intake of vitamin B12 rich foods like clams, sardines, and animal liver and kidneys seems ideal, taking supplements is highly recommended. This is due to their solubility in water, making them better and more quickly absorbed by the body than dietary B12.

3. Selenium

Selenium is another important supplement necessary for thyroid health. It helps with building the enzymes necessary to convert T4 toT3.
Selenium also helps out the thyroid gland by reducing inflammation and removing harmful substances.
The human body doesn’t produce selenium naturally, which is why partaking in selenium-rich foods like Brazil nuts, eggs, and dairy products is important. Opting for the best selenium thyroid supplements works as well.
Take note that overconsumption of selenium can cause complications with anxiety and sleep. The recommended daily dose for selenium is 55 micrograms.

4. Zinc

Zinc plays a vital role in thyroid function, as it lets T3 receptors bind to the hormone T3. When you don’t have enough zinc present, your body won’t be able to absorb T3 introduced into your body via diet and/or medications.
Zinc is also responsible for helping out with testosterone production, wound healing, and increasing insulin sensitivity. Foods rich in zinc include shellfish, legumes, seeds, nuts, whole grain, and dairy.
Zinc should also not be taken at the same time as certain antibiotics (Sumycin, Cipro, and Achromycin), as it will decrease the efficacy of both medications. You can remedy this by taking the antibiotics either 2 hours before taking your zinc supplements, or about 4-6 hours afterward.

5. Magnesium

Magnesium has a two-way function for your thyroid: first, it helps in the conversion of T4 to T3. It also helps boost T4 production, while preventing overproduction at the same time.
Magnesium also evens out blood sugar levels, promotes, bone development, and supports protein synthesis. It’s also well known as an aid for those having problems with sleeping.

6. Copper

Copper is an important micronutrient that helps to regulate levels of T3 in the body. A deficiency in copper can lead to inhibition in T4-T3 conversion, which in turn leads to an excess of T4 hormones in the bloodstream.
Copper works hand in hand with zinc in regulating the activities of the thyroid gland. They are often found together in the best thyroid support supplement in stores available for hypothyroidism, for example.
Foods that are rich in copper include liver, sweet potatoes, and oysters. To be able to achieve optimum copper and zinc teamwork, you should also avoid foods that deplete your body’s zinc levels, like refined carbs and alcohol.

7. Molybdenum

Molybdenum is a mineral that is usually present in the body that can be easily sourced and efficiently retained. It is also important for the production of energy and improving sleep quality.
Molybdenum has two functions in thyroid support: sufficient levels inhibit the buildup of fluoride in the thyroid gland, which can otherwise lead to thyroid toxicity. It also manufactures enzymes that release T3 hormones from the thyroid gland storage.
Foods that are rich in molybdenum include peas, lentils, nuts, whole grains, and eggs.

8. Manganese

Manganese is best known as a mineral that can help repair bones and maintain a healthy immune system. It is important for the thyroid system in two ways:

  • First, it helps transport T4 into the cells.
  • Second, it helps in protecting the thyroid gland from getting stressed out and worn down.

If you decide to opt for dietary manganese instead of supplements, manganese-rich foods include legumes, meats, nuts, and fish. Leafy greens are also a good option for manganese content, but look out for their iron content which could inhibit the body’s absorption of manganese.

9. L-Tyrosine

This is a type of amino acid that helps in the production of many hormones in your body. It also helps build neurotransmitters like dopamine, that famous feel-good brain chemical that does wonders for your mood.
L-tyrosine is also important for T3 and T4 production, making it a crucial part of supporting thyroid health. A deficiency in this amino acid could lead to lowered T3 and T4 production, which in turn can lead to hypothyroidism.
Adapting your diet is the best way to up your intake of L-tyrosine. Foods that are high in L-tyrosine include chicken, beef, green vegetables, and dairy products.
The best thyroid supplements also include L-tyrosine, and there are also several supplements in powder, capsule, and tablet form. But take note that taking l-tyrosine is only greenlit for those who have normal iodine levels, as it will only work when combined with this mineral.

10. Vitamin D

Vitamin D deficiency has strong links to hypothyroidism, and studies have shown that an increase of Vitamin D intake improved the TSH levels in patients with hypothyroidism.
Foods rich in Vitamin D include fortified dairy products like milk and yogurt, as well as orange juice. But dietary vitamin D may not be enough, and vitamin D supplements may be recommended by your doctor upon consultation.
Taken, orally, vitamin D supplements also provide a better source besides unprotected sun exposure. Though it is always best to ask your doctor if vitamin D can be taken in tandem with your specific thyroid medication.
What Is TSH? TSH is Thyroid Stimulating Hormone, also known as thyrotropin. It is produced by the pituitary gland and stimulates the receptors of thyroid cells, which prods them into producing T3 and T4.

11. Capsaicin

This is the substance responsible for making chili peppers so notoriously spicy. It surprisingly plays a role in treating hypothyroidism by helping to restore regular thyroid hormone production.
Capsaicin also helps alleviate symptoms brought about by hypothyroidism such as pain and poor blood circulation. Cayenne pepper is a choice spice that can be added to foods to reap the benefits of capsaicin, but if you’re not a lover of spice then capsaicin pill supplements are ideal.
Capsaicin in pill form appears in stores as cayenne pepper supplements. Consult your doctor when taking capsaicin pills, as they are known to lower blood sugar levels; you’d want to avoid this side effect as much as you’d want to avoid diabetes as it could cause lightheadedness and feeling of weakness.
