​Iodine: Excess And Deficiency

Thyroid weights approximately 12 to 25 grams. But despite such a low weight, this organ is responsible for the normal development of the human body. And the main ingredient that normalizes the functionality of thyroid is iodine.

Iodine: Excess And Deficiency

What is iodine?

Iodine is a substance which is fully responsible for the normal functioning of the thyroid gland. On iodine the functioning of the whole organism is dependent directly. From mood and full of sleep to pregnancy - all of these processes are directly dependent on the availability of the required amount of iodine in the body.

Iodine deficiency

Intellectual development is also dependent on the presence of iodine. According to the studies that have been conducted by the United Nations, about forty-three million people suffer from mental retardation due to iodine deficiency in the body.

If the body is deficient in iodine, there may be a manifestation of the following symptoms:

  • Irritability.
  • Drowsiness.
  • Intellectual impairment.
  • Memory impairment.
  • Lethargy.
  • Constant fatigue.

Iodine deficiency in the female body affects breast, causes menstrual irregularities, infertility.

Lack of iodine in the child's body manifests the following symptoms:

  • Violation of brain activity.
  • Cretinism.
  • Occurrence of deaf-mutism.
  • Reduction of calcium in the bones.
  • Violation of sexual development.
  • Brittle bones.


It should be remembered that iodine is not a substance that can synthesize the human body, so it must come together with food or nutritional supplements. Typically, the presence of the above symptoms, such as irritability, is not a cause for most people to visit the doctor. Many people try to compensate for the lack of iodine with various dietary supplements. But you should always keep in mind that with supplements one can not only compensate for the lack of iodine, but also get his overdose, which also has a negative impact on health.

Iodine excess

Hyperthyroidism is the main manifestation of an excess of iodine in the body. At the background of this disease may develop diseases such as Graves' disease, goiter, tachycardia, and others.

On the basis of iodine excess in the body, there can manifest the following symptoms:

  • Muscle weakness.
  • Irritability.
  • Emaciation.
  • Tendency to diarrhea.
  • Sweating.
  • Increased metabolism.
  • Hyperthermia.
  • Early graying.
  • Degeneration of the skin.
  • Depigmentation of the skin.
  • Muscle atrophy.

The dosage of iodine

Rate of iodine to enter the body every day is entirely dependent on age.

For children under five years the daily dose of iodine is equal to 90 mcg.

Children from 5 to 12 years should receive not less than 120 micrograms of iodine per day.

Teenagers and adults 150 micrograms of iodine per day.

During pregnancy and lactation, women should receive at least 250 micrograms of iodine per day.

We should remember that before you start taking iodine in supplements or drugs, you should consult with your doctor, as doing it by yourself can significantly harm your health!
