22 Foods Highest in Iodine

Iodine is an essential mineral that’s vital to the proper functioning of the thyroid. The thyroid gland is responsible for managing growth and metabolism. An iodine deficiency can cause symptoms such as fatigue, high cholesterol, lethargy, depression, and swelling of the thyroid gland. Prevent this dangerous deficiency by eating the right amount of iodine rich foods each day.

Baked Potatoes

In order to get the necessary nutrients, baked potatoes are a better option than mashed potatoes. Most of the important dietary staples, such as fiber, vitamins, and potassium are contained in the skin. Baked potatoes are also a great source of iodine; one medium potato provides about 40% of the recommended daily amount of iodine.

Serving Size (1 medium potato), 60 micrograms of iodine (40% DV), 161 calories.


Milk is usually the beverage of choice for anyone who’s worried about a calcium or Vitamin D deficiency. But milk also contains several other nutrients, including the essential mineral iodine. One cup of milk contains an impressive 56 micrograms of the mineral, or about 37% of what the average person must consume each day.

Serving Size (1 cup), 56 micrograms of iodine (37% DV), 98 calories.


Dried Seaweed

For iodine deficiency, dried seaweed is the go-to remedy because of its incredible supply of this essential mineral. A quarter-ounce serving contains 4,500 micrograms of iodine. That’s way more than enough iodine for the body to absorb in a day (3000% of the daily value, to be exact.) Consume smaller portions over time in order to gain the health benefits.

Cod is also a healthy source of protein, calcium, magnesium, potassium, and Vitamin E.

Serving Size (3 ounces), 99 micrograms of iodine (66% DV), 89 calories.

Fortified Iodized Salt

Iodine is often confused with salt, but the two are actually very distinct. In terms of chemistry, salt is classified as a crystal, and is composed of two elements: sodium and chloride. Iodine, on the other hand is a mineral. Many brands of salt are fortified with the essential mineral iodine. If you worry you’re not getting enough iodine, check to make sure the salt you’re using is fortified with iodine, and then enjoy it in moderation with a healthy diet and lifestyle.

Serving Size (1 gram), 77 micrograms of iodine (51% DV), 0 calories.


Seafood is usually a great source of iodine, and shrimp is just one example. A three-ounce serving of shrimp provides 35 micrograms of iodine, or enough to account for just under a quarter of the recommended amount each day. Shrimp also provides your body with other essential minerals, primarily protein and calcium.

Serving Size (3 ounces), 35 micrograms of iodine (23% DV), 84 calories.

Himalayan Crystal Salt

If you’re trying to avoid conventional table salt but you’re worried about not getting enough iodine, Himalayan crystal salt is a viable alternative.

Serving Size (3 ounces), 17 micrograms of iodine (11% DV), 99 calories.


Boiled Eggs

Hard boiled eggs are a versatile, healthy food that supplies the body with Vitamin A, Vitamin D, zinc, calcium, antioxidants, and more. They’re also consumed for their iodine content. One hard boiled egg provides just under 10% of the iodine needed for the day. For a light and healthy meal, slice a hard-boiled egg over a leafy green and veggie-filled salad.

Serving Size (100 grams), 100 micrograms of iodine (67% DV), 98 calories.
