Iodine is an essential trace element required for the production of thyroid hormones. It regulates metabolism, growth, and brain development, making adequate intake crucial for overall health throughout life.<\/span><\/p>\n

Daily iodine requirement varies by age and physiological status. Adults generally need around 150 micrograms, while pregnant and breastfeeding women require higher amounts to support fetal and infant development.<\/span><\/p>\n

Iodine deficiency leads to goiter, hypothyroidism, and developmental disorders. Salt iodization programs have significantly reduced deficiency worldwide, protecting populations from thyroid-related diseases.<\/span><\/p>\n

Adequate iodine intake also contributes to immune function and cognitive performance. Dietary sources include iodized salt, seafood, dairy products, and seaweed, supporting optimal thyroid and systemic health.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
Element Name<\/td>\nIodine<\/td>\n<\/tr>\n
Chemical Symbol<\/td>\nI<\/td>\n<\/tr>\n
Description<\/td>\nIodine is an essential trace element for the human body, playing a vital role especially in the production of thyroid hormones.<\/td>\n<\/tr>\n
Functions<\/td>\nUsed in the synthesis of thyroid hormones (T3 and T4), important for growth, development, metabolism regulation, and brain functions.<\/td>\n<\/tr>\n
Deficiency Symptoms<\/td>\nGoiter, fatigue, feeling cold, weight gain, dry skin, developmental delay in children, increased risk of miscarriage and birth defects during pregnancy.<\/td>\n<\/tr>\n
Excess Symptoms<\/td>\nHyperthyroidism, thyroid enlargement, rapid heartbeat, weight loss, irritability, sweating; toxic effects may occur with excessive intake.<\/td>\n<\/tr>\n
Daily Requirement<\/td>\nRecommended daily iodine intake is 150 mcg for adults, 220 mcg during pregnancy, and 290 mcg while breastfeeding.<\/td>\n<\/tr>\n
Sources<\/td>\nIodized salt, seafood (fish, seaweed), dairy products, eggs, some vegetables (grown in iodine-rich soil).<\/td>\n<\/tr>\n
Deficiency Risk Factors<\/td>\nUsing non-iodized salt, diets based on foods grown in iodine-poor soil, pregnancy, breastfeeding, vegan diets.<\/td>\n<\/tr>\n
Prevention of Deficiency<\/td>\nUse of iodized salt, iodine supplementation (especially in pregnancy), consumption of iodine-rich foods.<\/td>\n<\/tr>\n
Toxicity and Side Effects<\/td>\nExcessive iodine intake may negatively affect the thyroid gland; recommended amounts should not be exceeded.<\/td>\n<\/tr>\n
Uses<\/td>\nMedical imaging (iodine-based contrast agents), disinfection (iodine solutions), supplementation in the treatment of hypothyroidism.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
