Essential Facts about Iodine, an Essential Mineral

September 25, 2014

Let’s take a look at some of the essential facts about iodine, an mineral that’s essential for the body but few people know about.

Iodine is fundamental for your body. In fact, according to many studies, it’s the mineral that people around the world tend to lack the most since the body doesn’t synthesize it and it must come directly from your diet.

The problem also lies in the fact that there’s very little iodine in food, unless big industries have included it in their products (like iodized salt, for example). However, generally, the majority of iodine is found in the ocean, especially in seaweed.

Iodine is absorbed in the intestinal tract and is transported in the blood stream to the thyroid glandswhere it is stored to produce hormones. A good level of iodine helps you burn fat and prevent goiter and thyroid problems, among other things.

In this article, we’ll take a look at some of the essential facts about iodine.
