Iodine Sources

and Health

Vegetarians and vegans are often at risk for iodine deficiency due to the limited consumption of animal products in their diets. Iodine is an essential mineral that plays an important role in human health. It’s important for growth and development, thyroid health, and helps to keep the body’s metabolic rate optimal. The good news is that there are plenty of iodine sources for vegetarians and vegans that can help avoid deficiencies.


Seaweed is an excellent source of iodine. There are a variety of types of seaweed, such as nori, kelp, dulse, and wakame, which can be added to salads, soups, and other vegetarian or vegan dishes. Seaweed is also available dried, which can make it an easy addition to everyday meals. Additionally, seaweed is a great source of other essential minerals like calcium and potassium.

One underrated source of iodine is potatoes. Potatoes contain iodine, as well as other essential minerals and vitamins. They can be boiled, mashed, or baked to make a delicious side dish.


Eggs are a great iodine source for vegetarians, as they contain iodine and some much-needed protein. They can be boiled, scrambled, or used in recipes like omelets, frittatas, and quiches.


Table salt is the best and most affordable source of iodine for vegetarians and vegans. Most table salt is iodized, which means it contains iodine. Adding a pinch of salt can boost the flavor of a meal, as well as provide an important source of iodine. Just remember to use it in moderation, as too much salt can be harmful.
