Ingredient Science: Iodine—Thyroid Hormones, Growth and Development

Iodine is an essential mineral used by the thyroid gland to make thyroid hormones. Those hormones help regulate metabolism and are important for normal growth and neurodevelopment.

Dietary sources

Iodized salt, dairy foods, eggs and seafood are common sources in U.S. diets, although intake varies with food choices and the type of salt used. Specialty salts are not automatically iodized.

Why balance matters

Both iodine deficiency and excessive iodine intake can disrupt thyroid function. That is why iodine should not be approached as a “more is better” nutrient, especially in children with known thyroid disease or those taking medicines that affect the thyroid.

Supplement context

The AAP’s general guidance is food-first for most healthy children, with supplements considered when diet, deficiency or a medical condition creates a reason for them. When iodine appears on a supplement label, read the amount per serving and account for other dietary and supplemental sources.

Where it appears in DocVites

Iodine is included in the current formulations of DocVites Children’s Multivitamin with Prebiotics and DocVites Multivitamin Chewable Tablets. It is not part of the current DocVites infant multivitamin formula.
