Iodine | Health Benefits | Symptoms Of Deficiency

Basic characteristics of Iodine


Iodine belongs to the group of trace elements, next to iron, selenium, boron, molybdenum and other minerals.

Iodine was discovered in 1811. by French chemist Bernard Courtois (1777-1838). Name of mineral derived from the Greek word iodes, meaning the color purple.

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 that the iodine is an integral part of thyroid hormones - thyroxin and tree-iodine-thyroxin, which play a role in metabolic processes in the body, regulate body temperature and condition of all muscle nerve activity in the body.

The absorption of iodine can be reduced by the intake of foods which include cabbage, cauliflower, kale, Brussels sprouts, broccoli, mustard, soy, flax seeds, peanuts and more.


Health Benefits Of Iodine


1. Regulation of the thyroid gland’s work

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

Each Lack of iodine conduit to a state labelled as - hypothyroidism, or decreased thyroid hormone secretion.

In contrast to the slow work of thyroid gland, due to an excessive ingestion of salt, comes up a condition with increased secretion known as hyperthyroidism.

2. The regulation of body temperature

3. Regulation of body weight

4. Impact on psycho physical condition

5. The impact on the health of skin, hair and nails

6. Impact on pregnancy and foetal development amounts

7. The impact on the proper functioning of the cardiovascular system (arteries clean, prevents infarct, stroke, atherosclerosis)

8. Iodine from the body removes heavy metals - fluoride, bromine, mercury, cadmium, arsenic, aluminium.

9. Affects the proper growth and development

10. Today's research shows a link between iodine and cancer prevention

The daily need for iodine will be satisfied if ingested 100- 150 mg. 

For pregnant women and nursing mothers the recommended doses are between 160 and 200 milligrams per day.
