Product Overview


  • Foundation for Longer Life
  • Iodine with Sea Plant Complex
  • Dietary Supplement


For decades, Americans have been told to avoid table salt. But when iodized table salt is reduced, people can unknowingly lower their iodine intake to suboptimal levels. Analyses from the National Health and Nutrition Examination Survey (NHANES) show that urinary iodine levels have plummeted since the 1970s.

The good news is that you can avoid iodized table salt without sacrificing the health benefits of iodine. Sea-Iodine is a low-cost proprietary formula that health-conscious individuals can take each day to support optimal iodine levels. Using natural ingredients harvested from a blend of organic marine algae, Sea-Iodine brings you the health of the sea while avoiding the dangers of excessive salt intake. The algae found in Sea-Iodine provide you with over 667% of the Recommended Daily Value of natural iodine.

Iodine is a health-promoting trace element essential for life. Its primary biological role lies in the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). T4 and T3 contain four and three atoms of iodine per molecule, respectively. The thyroid gland actively absorbs iodide from the blood to make and release these hormones into the blood.

Iodine happens to be found abundantly in sea vegetables and plants. In areas where no marine foods are eaten, people have lower iodine levels. For this reason, US commercial salt makers have long added iodine to deliver this key ingredient to your diet. However, we now know the concerns associated with eating too much table salt, which resurrects the dilemma of where to get healthy sources of iodine.

Ironically, health-conscious people are often the most likely to develop low iodine levels. One reason is that athletes and people engaged in heavy physical effort deplete their natural stores of this trace mineral through perspiration. Vegetarians also have a substantially greater likelihood of low levels of iodine than carnivorous people, since foods of plant origin are less rich in iodine than animal-derived foods. One study demonstrated iodine deficiency in 25% of vegetarians and an incredible 80% of vegans.

For those who would like the convenience and economy of taking vitamin D along with their Sea-Iodine all in one pill, Life Extension also offers Vitamin D3 with Sea-Iodine.

Almost felt immediate effect. Used to use kelp before, but this one is more efficient to me.

Thanks for your feedback!

Provides an Energy Boost

Posted by iHerb Customer on Feb 15, 2018 | Verified Purchase

Having tried lots of supplements in an attempt to boost my energy, most of which were unsuccessful, I wasn’t expecting too much from these little pills. However, after reading that iodine was the missing link in our energy production I decided to give them a go. Imagine my surprise when I felt a difference from the very first pill? I even stopped taking my other energy pills to make sure it was the iodine. It was, a fact confirmed when I was without them for a week.

Thanks for your feedback!

need for iodine

Posted by iHerb Customer on Jan 23, 2018 | Verified Purchase

we need iodine and it has been eliminated in some of our regular food products

Thanks for your feedback!

Made from kelp which is great

I love these because they are made from kelp. Regular iodine can be toxic if you take too much, but kelp is not dangerous in high doses from what I've read. Gives me piece of mind. Recommended.

probably good product but maybe the dose is too high

Posted by iHerb Customer on Sep 23, 2017 | Verified Purchase

I heard that too much of a good thing like Iodine can lead to problems of the thyroid, and that most diets released enough without supplementation. If you want to take it I suggest you don't take it for an extended time.
