Jódkiegészítés

Jódkiegészítés refers to the practice of supplementing the diet with iodine, an essential trace element. Iodine plays a crucial role in the production of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). These hormones are vital for regulating metabolism, growth, and development, particularly in children and during pregnancy. Iodine deficiency can lead to a range of health problems, the most well-known being goiter, an enlargement of the thyroid gland. More severe deficiency can result in hypothyroidism, a condition characterized by a low thyroid hormone level, leading to fatigue, weight gain, and cognitive impairment. In pregnant women, iodine deficiency can cause irreversible developmental problems in the fetus, including intellectual disability.

The primary dietary source of iodine is iodized salt, a common additive in many countries. However, reliance on iodized salt may not be sufficient for everyone, especially those who consume less processed foods or live in regions with low soil iodine content. Other natural sources include seafood, dairy products, and eggs, but the iodine content can vary significantly. Consequently, individuals at risk of deficiency, such as pregnant and breastfeeding women, or those with specific dietary restrictions, may consider iodine supplements. The recommended daily intake of iodine varies by age and physiological status. Excessive iodine intake can also be harmful, potentially leading to thyroid dysfunction, so it is important to adhere to recommended dosages and consult a healthcare professional before starting supplementation.
