Iodine is an indispensable element for our body.
Together with food, we get a lot of vitamins, macro-and micronutrients, amino acids, minerals and other substances necessary for the normal functioning of the body. And every such substance is necessary and indispensable. For example, normal thinking is impossible without iodine. And why is he still needed?
Why do I need iodine?
So, why does the body need iodine so much? Everyone knows that it is useful for the thyroid gland. And this is actually the case. But the fact that without the thyroid gland, we could not live, few realize.
Iodine entering the body is absorbed into the blood, and from there it enters the thyroid gland, after which this important organ begins to produce specific hormones (thyroxins), which are necessary for the normal operation of several body systems at once. For example, they are needed for the brain, as they provide its normal activity. Also, thyroxin is involved in the processes of heat exchange and energy metabolism.
This hormone is also important for water-salt balance, as well as for ensuring the functioning of the nervous system. In addition, this substance is also involved in the regeneration and formation of body tissues.
Thyroxin is also useful for the cardiovascular system. In general, the thyroid gland is indispensable, and it cannot work normally without iodine. In addition, it is necessary for the normal formation of the fetus during pregnancy and for the harmonious development and growth of the child.
It is noteworthy that the thyroid gland takes about 90% of all iodine entering the blood, and not all the amount that was consumed with food reaches the blood. And if the products are not so rich in iodine, there will be a shortage.
If the food does not allow you to receive the required amount of iodine, then its deficiency will certainly occur. The first to suffer from this will begin the thyroid gland.
And then other organs will also experience the deficit: brain activity will deteriorate, many metabolic processes will be disturbed, tissues will recover much slower, immunity will weaken, diseases will become frequent and long-lasting, the nervous system will also work with impairments.At first, all this may be imperceptible, but then obvious signs will certainly appear.
Here are some symptoms of iodine deficiency:
- fatigue, constant fatigue, drowsiness, decreased performance;
- frequent colds and infectious diseases;
- shortness of breath, pain in the heart;
- decreased concentration, memory loss;
- loss of appetite;
- hair loss, their fragility;
- peeling, dry skin;
- deterioration of the teeth;
- hearing loss;
- apathy, melancholy, depressive states;
- disruption of the menstrual cycle in women;
- problems with potency in men;
- weight gain for no apparent reason;
- an increase in the size of the thyroid gland (this manifests itself in the form of a goiter, which looks like a lump on the neck);
- irritability, increased nervous irritability.
Determine iodine deficiency by using a simple test. Apply to any part of the body iodine grid and follow it. If the traces disappear in just a few hours, then there is a clear disadvantage. If after a day iodine remained on the skin, then everything is in order.
The rate and excess of iodine
Iodine is necessary for everyone, but perhapsthe only contraindication to its use is its normal amount in the body. The fact is that excess iodine is no less dangerous than its lack. Again, the thyroid gland will suffer, and behind it other systems, depending on the work of this organ.
To avoid problems, you need to know the dosage and follow them.
- Preschool children need 100 μg daily.
- Schoolchildren need more because of increased brain activity. The daily rate is about 150 micrograms.
- An adult needs 200 micrograms per day.
- The need for iodine in pregnant women is increasing. The daily dose is 250 micrograms. Approximately the same amount is necessary and lactating mothers.
The maximum allowable amount should not exceed 300 μg.
The rate of consumption depends on weight, according to some doctors. To determine your individual dose, you can multiply your weight by 2 or 3. That is, about 2–3 mcg of iodine should fall on 1 kilogram of a person’s weight.
With an excess of iodine, the following symptoms may occur:
- goiter formation;
- lesions of the mucous membrane of the eye (blepharitis, conjunctivitis), accompanied by burning, redness, increased tearing;
- lesion of the mucous membranes of the respiratory tract, manifested in the form of cough, runny nose, persistent sore throat;
- skin manifestations: pustules, acne, urticaria, dermatitis, dryness and peeling;
- headaches, dizziness;
- unusual taste in the mouth;
- weight loss;
- reduced visual acuity;
- frequent colds;
- excessive sweating;
- muscle weakness;
- heart rhythm disturbances (eg, tachycardia);
- increased nervous irritability, insomnia.
To determine the excess will help blood and urine tests.
How to get iodine from food?
To prevent a deficit, you need to eat foods that contain iodine. Usually with a normal lifestyle and living in favorable conditions, this is enough.
There are many products that have in the composition of iodine. And which ones contain the greatest amount of it? We list these:
- Seafood: squid, shrimp, sea, scallops, midi and so on.

- Milk and dairy products. Eat cheeses, butter, sour cream, kefir, yogurt.
- A lot of iodine is present in seaweed, so be sure to include it in your diet.

- Feel free to eat persimmon.
- In buckwheat, iodine is also contained.
- Yolk of eggs is also useful from this point of view.

Let us dwell on the doses and methods of administration:
- For the prevention of iodine deficiency, children are prescribed from 50 to 100 micrograms daily. Adolescents should take 150 mcg per day, and adults about 200 mcg. Pregnant doctors are often advised to use 250 mg daily. Prevention is carried out by courses for 2-3 months, only 2-3 courses are required annually.
- If the deficit already exists, then children and adolescents should take from 100 to 200 micrograms per day, and adults under the age of 45 years approximately 300-500 micrograms.The course of treatment can last a month or two for children and adolescents and six months for adults.
