Need for Iodine

Iodine and its derivatives are indispensable in a wide range of nutritional, pharmaceutical and industrial applications.

For optimal development of growth in humans and animals, adequate iodine intake is imperative. Iodine is an essential constituent of the thyroid hormones, and 80 per cent of the iodine in the mammalian body is found in the thyroid gland. Iodine deficiency disorders (IDD) occur when sufficient iodine lacks in the diet. Mild deficiencies can cause mental and physical retardation in humans, and skin-disorders or loss of production in livestock and poultry. More severe effects of IDD include goiter, a swelling at the front of the neck caused by the increase in size of the thyroid gland, abnormal physical development and reproductive loss. The iodine content in diets needs to be balanced. Too much iodine can also compromise thyroid function.
