Iodine is one of nature's most crucial trace minerals for human health, but it's also one of the most frequently overlooked. Iodine facilitates a wide range of normal bodily processes. It helps maintain thyroid function by supporting a normal hormone balance. Because of the position it occupies on the Periodic Table of Elements, it may also help displace the body's absorption of fluoride, bromine, and chlorine. It's also an important nutritional element for fetal development.
