Food Sources of IodineIodine is an essential trace mineral, or micromineral, meaning we require smaller amounts of it compared with macrominerals, such as calcium.

The primary role of iodine in mammalian biology is to support the synthesis of thyroid hormones.1,2 Iodine also plays an important role in fetal neurodevelopment/cognitive development in children.3,4 Iodine has also been shown to support normal breast tissue in women.4

Who is at risk of not getting enough iodine?

  • Residents of developing countries5
  • Vegetarians and vegans5,6
  • Pregnant and breastfeeding women4,5

Those who are deficient, at risk of deficiency or whose diet may be lacking should focus on including more whole food sources of iodine and consider supplementing to ensure adequate intake. Thank you to the Vegan Liftz community for including Life Extension’s Sea-Iodine™ in your ‘Best Vegan Iodine Supplements’ Buyers Guide.

Salt as a Source of Iodine

sea salt and Himalayan do not have as much iodine as iodized saltIn addition to the list above, iodized salt is a major source of iodine. Seafood contains the highest amount of iodine by weight compared to other foods. However, unfortified sea salt only contains a small amount of iodine. For cooking, chefs and consumers may choose sea salt or Himalayan salt as an alternative to table salt (iodized salt) for flavor, texture and their small amount of mineral content aside from sodium. Notably, these options do not have as much iodine as iodized salt.

Iodine in Plants

When it comes to fruits, vegetables and legumes as a source of iodine, the amount varies due to the quality of the soil, which depends on the region and growing practices.5,6 Other important minerals, such as the macromineral magnesium, are also affected by variations in soil quality.
