What is the typical daily dosage of Iodine?

The typical daily dosage of iodine for adults is generally recognized as 150 micrograms (mcg). This amount is established based on dietary recommendations and is considered sufficient to meet the thyroid's need for iodine, which is essential for the synthesis of thyroid hormones. Insufficient iodine intake can lead to conditions such as goiter and hypothyroidism due to impaired hormone production.

While lower dosages are recommended for certain populations, such as pregnant and lactating women who may require more (around 220-290 mcg respectively), the standard recommendation for the general adult population is 150 mcg. Therefore, this dosage supports normal thyroid function and overall health.

Other options indicate higher amounts that exceed what is generally recommended for daily intake in the average adult, which could contribute to iodine excess or toxicity in some cases.
