Iodine, EU NRV (Nutrient Reference Value) 150 µg per day.
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 contributes to the normal production of thyroid hormones and normal thyroid function.
Iodine also supports the normal growth of children.
Iodine is greyish-black in colour. It forms a component of thyroxin, the main hormone produced by the thyroid gland.
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.
