In the body, most iodine is deposited in thyroid gland about 70-80%, while the rest is in other organs. 

Iodine is associated with thyroid gland by the reason - iodine is an integral part of thyroid hormones - thyroxin and tree-iodine-thyroxin, which play a role in metabolic processes in the body. 

They regulate body temperature and have affection on condition of all muscle nerve activity in the body.

Iodine is an ingredient of the thyroid gland hormones, and is responsible for the implementation of the normal metabolic processes of proteins, fats and carbohydrates. 

Each Lack of iodine leveled up to a state labelled as - hypothyroidism, or decreased activity and decreased thyroid hormone secretion. 

In contrast to the slow work, there is also another disturbance in the work of the thyroid gland and a condition known as hyperthyroidism.
