Iodine: What is it +Why we need it

Almost everyone has heard the terms hypo- and hyperthyroidism, but how many know the role that iodine plays in the function of the thyroid and overall health? Although, it is an essential nutrient – many do not realize that they are deficient. It is especially important that women who are thinking about getting pregnant or are currently pregnant be aware of their levels. Let’s take a closer look at what iodine is and why our body needs it.

What is it?

Iodine is an essential nutrient that our body depends on the consumption of it through food + supplements. The best sources are…

  • Seafood
  • Seaweed
  • Dairy
  • Eggs
  • Table Salt

This nutrient is used to make thyroid hormones, which regulates your metabolism, heart rate, and temperature.

Iodine Deficiency = An Unhappy Thyroid

Two major consequences for women that have lower levels are possible infertility and poor fetal neurodevelopment. Because your needs are greater during pregnancy, supplements are necessary. Therefore, if you are planning to get pregnant in the near future is it never too early to start building up your levels. In the JAMA, it states that a deficiency can cause infertility…

Compared with women with normal iodine levels or mild iodine deficiency, women with iodine-creatine ratios lower than 50 μg/g had a 46% lower chance of becoming pregnant in any menstrual cycle.

Below is a list of a few other consequences that deficiency can lead to:

  • Hypothyroidism
  • Goiter (enlargement of the thyroid)
  • Poor cognitive development
  • Cretinism (Mental Retardation and other physical development issues)

Honestly, even with my background in nutrition, this nutrient was not at the top of my list of concerns when I became pregnant. I am happy to say that prenatal vitamins include this vital nutrient. So, although a deficiency is a serious issue, especially when pregnant or lactating, there are many options out there to help insure that you keep your iodine levels in check!

How to Spot Deficiency and Treatment Options

Iodine deficiency can only be diagnosed with clinical tests. Some symptoms of iodine deficiency can be, but not limited to, weight gain, fatigue, memory issues, feeling colder, hair loss, and more! If you are having any issues with your thyroid, are planning to come pregnant, are pregnant, or you are lactating, checking your iodine levels is never a bad idea.

Tests to request:

If your levels are low, you can easily start to include more in your diet with supplementation. Non-pregnant adults should be getting 150 μg/day, whereas pregnant and lactation adults need 250 μg/day according to the WHO recommendation. I highly recommend getting levels tested, instead of guessing you “may have a deficiency” because getting too much can cause harm as well. This nutrient needs to be well balanced.

Although excess exposure generally does not result in any apparent clinical consequences, thyroid dysfunction can occur in vulnerable patients with specific risk factors, including those with pre-existing thyroid disease, the elderly, fetuses and neonates.
