What is the Best Iodine Supplement in 2017?

The benefits of adding iodine into your diet have been known for decades. Iodine supplements can potentially improve thyroid function and may even have a positive effect on the reproductive system. In this article, we’ll discuss what iodine is and find out which of these benefits are supported by science.

Why Choose an Iodine Supplement?

Not many foods contain iodine. Iodine is present mostly in foods that are typically not considered desirable. It’s likely that you’re not often craving seaweed, lima beans, or prunes. (source)

To get the recommended dosage of iodine for treating thyroid conditions, you would need to consume a whopping 10 cups of lima beans. Furthermore, you probably won’t want to eat the 50 prunes a day to get your thyroid on track.

You may be more inclined to try iodine rich foods such as sea vegetables. However, the levels vary from plant to plant too much to get an accurate dosage. One sheet of dried seaweed can contain anywhere from 11% of your daily value to 2,000%.

Iodine supplements dosages are consistent and pure. (source) If you’re looking to get your thyroid functioning properly and balance your metabolism, you might want to consider the supplement route, under the guidance of a healthcare professional.

How Do Iodine Supplements Work?

Iodine supplementation aids the thyroid in creating thyroid hormone. Iodine is an essential component of both thyroxine (T4) and triiodothyronine (T3) (source)

Who Should Take Iodine Supplements?

It is rare for those in the United States to be deficient in iodine. Iodine supplementation is beneficial for those who are suffering from hypothyroidism. Taking an iodine supplement without proper guidance from a physician can negatively impact the thyroid, so it is important to seek the opinion of a medical professional prior to beginning any type of iodine regimen.
