Iodine, New RDA* 150 µg
Iodine was one of the first minerals to be recognised as vital for good health. It is still considered one of the most important.
Iodine is greyish-black in colour. When heated, it yields corrosive fumes of a rich violet colour. In the human body, it forms an essential component of thyroxin, the main hormone produced by the thyroid gland.
The excessive consumption of certain foods like cabbage, cauliflower, and radish can cause iodine deficiency. These foods contain a substance which reacts with the iodine present in the food and makes it unsuitable for absorption.
Iodine, as iodide, is present in multivitamin and mineral supplements (providing up to 0.49 mg iodine/day) and is a component of kelp products
