Some of the supplements on this page are very dangerous. They can cause your body to over-reproduce your own thyroid hormone, which can cause thyroid problems such as hypothyroidism, hypothyroidism, Graves' disease, and many others. For that reason, I don't recommend all of them. If you decide to buy some of the products below, make sure to read the label.
These are some of the most popular supplement companies that sell thyroid supplements. Many of them sell all of their products for less than 1/10th the price that you would pay in the US market. Many of the companies on this page also have their own "homeopathic" supplements. These supplements are often sold in "liquid forms," which are made from sugar and water. Many of these products can be used to help you build up your thyroid, without the need to take any supplements. Some of these products are marketed under the names of natural products, such as tea and cranberry juice.
The above list is only a small portion of the supplements that you can buy in your local grocery store.
