What is "iodine"?
Iodine is an essential mineral that is crucial for the production of thyroid hormones, which regulate metabolism, growth, and development. These hormones are vital for brain development, especially during pregnancy and early childhood. Iodine is naturally found in seawater and soil, and it is commonly added to table salt to ensure enough intake. Good dietary sources of iodine include seafood, dairy products, eggs, and iodized salt. Getting enough iodine is important to prevent thyroid disorders such as goiter and hypothyroidism, and to support overall metabolic health and cognitive function.

Iodine can sublime when exposed to air, changing from a solid to a purple gas without melting.
