Top 5 Best Iodine Supplement To Buy In 2023

Iodine is an essential mineral, meaning your body needs it to function properly. You can’t produce it independently and must ingest it through your diet or as a supplement. It isn’t just an important trace element though. Iodine also impacts a variety of key biological processes in the body, including thyroid function and immune system support. Although iodine is found in many foods, there are still many people that don’t get enough of this mineral in their diet to meet biological needs. 

Iodine is essential for a vibrant and radiant body. It’s important to the body in many ways, including supporting immune system function, metabolism, and even cardiovascular health. Furthermore, it’s estimated that more than half of the U.S. population suffers from insufficient levels of iodine. Iodine is a major contributor to the function of your thyroid gland, especially in the creation of T3 and T4 hormones, which are important for regulating metabolism.

Iodine is an element found in small amounts in your body. Your body needs iodine to make thyroid hormones, which regulate your growth, metabolism, and other important functions.

Iodine is an essential component of thyroid hormones. The thyroid gland uses iodine and the amino acid tyrosine to make two hormones: triiodothyronine (T3) and thyroxine (T4). These hormones control how much energy your cells use — making them important for regulating body temperature, heart rate, muscle strength, weight, and many other functions.

Iodine deficiency can lead to hypothyroidism (underactive thyroid), goiter (enlargement of the thyroid gland), mental retardation, cretinism (severe mental retardation) and other problems. Iodine deficiency during pregnancy can also cause stillbirths and birth defects such as cleft palate.
