Why Do People Take Iodine?

Iodine is an essential trace mineral, meaning your body needs it but cannot produce it on its own. Here's why it matters and why people choose to supplement it.

Supports Thyroid Function

Your thyroid gland uses iodine to produce hormones that support normal metabolism and overall energy balance. Without adequate iodine, thyroid hormone production can be affected. Getting a moderate, consistent amount of iodine — whether through iodized salt, iodine-rich foods, or a supplement — helps support normal thyroid function.

Supports Healthy Pregnancy and Development

Iodine needs increase during pregnancy and breastfeeding, since the developing baby relies on the mother's iodine intake to support normal neurological development. If you are pregnant or nursing, talk to your doctor about your iodine intake — this is one of the most well-established reasons healthcare providers recommend adequate iodine intake.

A Note on Dietary Sources

Iodine is naturally found in seafood, dairy, and iodized salt. People following vegan, vegetarian, or low-sodium diets — or who don't use iodized salt — may be more likely to fall short of their dietary iodine needs, which is one reason some choose to supplement.

Before You Start

Talk to a healthcare provider before beginning iodine supplementation, particularly if you are pregnant, nursing, taking medication, or have a thyroid condition.
