Iodine is primarily needed by our body for the synthesis of thyroid hormone, which then regulates our body’s metabolism.
Natural sources of iodine are fish and seafood, but it is also found in eggs, meat, dairy products, and legumes… Iodine concentrations in food vary considerably depending on the climate in which the food was grown. However, the main source of iodine in the diet is iodized salt, which must legally contain 15–23 mg of iodine per kilogram of product.
Iodine deficiency leads to reduced production of thyroid hormones, which manifests as goiter.
The recommended daily intake of iodine varies, so it is 50-120 mcg for children, 150 mcg for adults, and 200 mcg for pregnant and lactating women. Iodine supplementation with different food supplements should never be done on your own, as it can cause irreversible damage to the body. Too low or too high amounts of iodine affect all functions in the body, from the metabolism of fats and carbohydrates to disorders of cognitive and psychological functions. If a person suspects a lack of iodine in the body, it is best to contact their doctor, who will then conduct tests and determine whether it is necessary to supplement iodine and in what quantity.
The bactericidal effect of iodine is also known, and it is also used as a disinfectant and antiseptic for skin and mucous membranes.
