8 Great Sources of Iodine

Prunes contain iodine

A healthy diet is a great way to ensure you receive a good balance of the nutrients your body requires, including iodine — and you need to make sure you always have enough iodine. Your thyroid depends on it to function and it is the primary element of two essential hormones that regulate metabolic function. Without it, a myriad of problems can occur, including hypothyroidism and reductions in energy.

What are some of the best sources of iodine? In this case, the best place to start is the sea…

1. Sea Vegetables

Oceans contain most of the world’s naturally occurring iodine. As a result, many of the edible plants we harvest from our saltwater seas also contain healthy values of iodine. Dulse Seaweed, Kelp, Kombu, Nori, Sea Palm and Wakame contain iodine. [1] [2] Although these sea veggies offer varying amounts of iodine, they still top the list as one of the best sources for naturally occurring iodine.

2. Seafood

It’s important to be aware of the presence of toxic metals in some fish… unfortunate but true. And, depending on your diet, you may not even eat fish. But, if you do, wild caught, deep water fish like Cod, as well as shellfish and shrimp also offer healthy values of iodine.

3. Eggs

Same goes for eggs, not on everyone’s plate but it is worth mentioning that this nutrient powerhouse has been recommended for pregnant women and young children specifically for its iodine content. [3] One egg contains nearly 16% of the recommended daily value of iodine. Cage-free, organic, and vegetarian fed are a must. If you’ve got a yard, give a thought to even getting your own chickens.

4. Organic Dairy

Not everyone consumes dairy but some people do, for those folks, do know that one cup of milk contains more than one-third of the recommended daily value of iodine. Yogurt and cheese also contain iodine. Cheese contains a lower value of iodine per serving; however, one cup of yogurt contains more iodine than a cup of milk – 50% of the recommended daily value! [1] Recent studies have found that individuals who regularly consume dairy receive good iodine supplementation. [4] This is one choice especially where organic is a must, and preferably raw.

5. Strawberries

These delicious summer berries provide a surprising source of dietary iodine. One cup of strawberries will provide 10% of the daily value. Plus, they have a good amount of vitamin C too!

6. Prunes

Constipated? Eat some prunes. But more than that, prunes offer a lot more than fiber. Like strawberries, prunes provide a healthy serving of iodine and other powerful nutrients in an easy to digest form.

7. Spinach and Dark Leafy Greens

Spinach, turnip greens and swiss chard have been specifically noted for their dietary iodine values. [5] These nutrient dense veggies also offer a highly bioavailable food source for easy digestion.

8. Dietary Supplements

If you’re not getting enough iodine in your diet, for crying out loud, do not simply shrug it off as a loss. Iodine deficiencies can cause problems and it’s so easy to avoid that mess. A nascent iodine (the best) supplement like Detoxadine is easy to add to your daily routine and does not cost a lot. Regardless if you choose Detoxadine or another product, be sure that you select a product that offers the most bioavailable materials. There are many fine products available, but there are also supplements that have been created in a lab and include artificial versions of nutrients — versions the human body may not recognize as well.

Eat these foods, take a supplement if you need one, and make sure you get enough iodine to keep your thyroid healthy and your metabolism charged!

    You mention in your recommendations that iodine is available from several sources, including sea veggies and sea food. That is obvious, as there is iodine in seawater. However, when you mention the other sources, you are assuming there is iodine in either the animal feed or in the soil the plants are grown in. That is a VERY dangerous assumption, since iodine can be a relatively rare mineral in soil.

    My background. My company, Mighty Grow Organics, manufactures poultry litter based fertilizers. I add a trace mineral package to all of my product, a mineral pack that contains naturally occurring iodine. I am working to develop biofortification techniques to increase the mineral content of garden veggies and forages. I will initially focus on the leafy greens, such as spinach, since from all my research they take up trace minerals the easiest and are the best at absorbing foliar nutrients.

    Thanks for the article. It is a very important issue and should be addressed more.

    Michael Labelle is quite right. You will have a heck of a time trying to get sufficient Iodine from sources other than seaweed. It would be nice to see some numbers here: the Iodine content of foods, and the Iodine deficit in people. Those numbers would startle a lot of people into needed supplementation. Also, consider the effects of Chlorine, Bromine, and Fluorine; they run the Iodine out of your body. We didn’t have this problem until modern times. One needs more Iodine than ever before, and cannot get enough without supplementation or eating a lot of seaweed. I’d recommend Lugol’s Solution; cheap and effective.

    Now with the Fukushima fiasco a full blown disaster, eating Pacific Ocean fish and seafood is now out of the question for the rest of our lives.

    Thanks for the information Michael, those are some important points to consider. Your company’s product sounds very interesting, what other nutrients do you add? Noticeable results in the end, harvested product?

    You’re correct, there is no way eating a lot of strawberries alone is going to provide your body with enough iodine. Seaweed is among the best dietary options, anything else is mostly a factoid.

    Thank you also for bringing up chlorine, bromine, and fluorine. These are all among the environmental toxins we have working against us.

    Ugh, it certainly seems that is a possibility, Syren. Fish are being found in that region with radiation levels 2500x over the limit — at minimum.
