Natural Thyroid Support

Updated: May 17


What does the thyroid do in the body?


Your thyroid plays a role in a wide variety of functions in the body including your metabolism, body temperature, heart rate, fertility, and even digestion.


If your thyroid is not functioning correctly you can experience fatigue, constipation, hair loss, frustrating weight gain, anxiety, and trouble sleeping.


Since these symptoms are also tied to many other conditions, the best way to determine if your thyroid is functioning correctly is through lab testing. To get accurate information, you need to test more than just your TSH level.


Did you know your TSH level is not actually produced by the thyroid? So why is it the first thing we test for when checking for an abnormal thyroid?

TSH is produced by the pituitary gland in the brain and its role is to stimulate the thyroid to produce thyroid hormones T4 and T3. I always recommend a full thyroid panel to make sure we have an accurate look at how the thyroid is functioning.


Comprehensive Thyroid Testing

A full thyroid panel includes pituitary (brain) hormone TSH as well as the thyroid hormones - T3, T4, reverse T3, and thyroid antibodies. We can look at the communication between the brain and thyroid when a full thyroid panel is done.


You can ask your doctor to order a full thyroid panel and go through insurance, or you can order your own thyroid panel with Ulta Labs, a popular nationwide laboratory. Ulta Labs has their Thyroid Panel - Basic Plus for $79. Find the thyroid panel and order it here.



It is important to have support and the right health care team behind you! Find a health professional who can help you understand the process and guide you through a supportive and natural healing process that you feel comfortable with.



In this article we will cover what foods and nutrients are best for supporting thyroid health. This article benefits women who want to prevent thyroid disease, women who have thyroid disease, and women who no longer have a functioning thyroid.



What if you don't have a functioning thyroid anymore?


If you no longer have a functioning thyroid, then you are actively taking thyroid medication and your body still needs to convert T4 into T3 active thyroid hormone, so these nutrients are important for all.


Nutrients for Thyroid Function

What food and nutrients that are important for thyroid health?


Each of these nutrients listed below play an important role in the function of your thyroid, however you need to make sure you are replenishing all nutrients in order to prevent imbalances and deficiencies. For example, supplementing with iodine if you have low selenium can actually make thyroid disease worse.



Selenium


Selenium is an important nutrient because it is needed for the enzyme that converts T4 hormone into the active T3 hormone. If your body is deficient in selenium then hypothyroidism can develop due to low levels of thyroid hormone available.


Selenium is found in liver, seafood, and red meats. Selenium can also be found in Brazil nuts, but the amount present depends on the soil content. Unfortunately the range of selenium in 1 ounce of Brazil nuts can range from 55 mcg to 550 mcg.


Here is the supplement I recommend in my practice: Ecological Formulas Kelp



Iodine


Iodine is essential for thyroid hormone production because the thyroid gland actually uses iodine with the amino acid tyrosine to create thyroid hormone. We only need about 150 micrograms (mcg) of iodine per day for optimal thyroid function.


3 oz. of cod has 99 mcg iodine 3 oz. shrimp has 35 mcg iodine

In the past, iodine deficiency was such an epidemic that the government ruled table salt needed to be fortified with iodine. This is why we have “iodized salt” as your general table salt.

It is important to know that too much iodine can stop thyroid synthesis, which is why many women with thyroid disease should avoid using iodized salt and other fortified foods to prevent excess iodine levels.


Avoiding fortified foods and choosing a high quality supplement with iodine and selenium will help to keep your nutrient levels balanced.

Vitamin D


We call this a vitamin, but vitamin D functions more as a hormone in our bodies. This is why vitamin D deficiencies are significant and associated with autoimmune conditions, including Hashimoto’s (thyroid autoimmune disease).


The best way to get vitamin D is through our skin’s own production. However, it depends on where we live in the world, if we are able to get enough UV light from the sun to produce sufficient levels of vitamin D in our body. Here in the Midwest it is not likely we can make enough vitamin D outside of a couple of summer months.


Also, if you are like me and fair-skin then being in direct sunlight with no sunscreen for the 30 minutes necessary to produce enough daily vitamin D, is not a great idea (or pretty for that matter). If you have darker skin you need to be in direct sunlight with no sunscreen for a longer period of time, potentially 2 hours per day to make enough vitamin D.


This is why vitamin D supplementation is recommended for most adults. Vitamin D is fat-soluble meaning you should take this supplement with a fat-containing meal, ideally later in the day for optimal absorption. Most adults benefit from taking 2000 IU vitamin D3 daily. I also recommend that you find a supplement that includes vitamin K2, because it works with vitamin D and calcium to be absorbed into bones and maintain bone health.


Here is the Vitamin D supplement I recommend in my practice and use myself: Ortho Molecular Liquid Vitamin D with K2 or if you prefer capsule form, Designs for Health Vitamin D Synergy.



The Best Foods for Thyroid Health


Omega 3 Fatty Acids


There are a few different types of essential fatty acids that our body needs. Because of our diet and high prevalence of chronic inflammation, our balance of omega-3 fatty acids is depleted. Fatty acids are necessary for all of our cell membranes, energy production, and brain health.Omega-3 fats are specifically involved in the anti-inflammatory pathways in the body.


If we have inflammation present in our bodies (which we all do) and not enough omega-3 fatty acids, our thyroid function can actually decrease because it is needed for thyroid receptors (converts T4 to T3).


The best sources of omega-3 is cold water fatty fish like salmon, sardines, herring, and oysters. Some plants also have omega-3 sources, but the plant form still needs to be converted into omega 3’s EPA and DHA form, which the body does not do well.


When choosing an omega-3 supplement, make sure to find one that is third party tested and free of heavy metals, pesticides, solvents, PCBs, and other contaminants.


Here is the Omega-3 Fish Oil supplement I recommend in my practice and use myself: Nordic Naturals Liquid Omega 3 Lemon, or if you prefer capsule form Metagenics Omegagenics.



Magnesium


Magnesium is a powerful mineral that participates in over 300 enzymatic reactions in the body. It is estimated that up to 75% of the US adult population is low in magnesium (1)


You can find magnesium in green vegetables, especially dark leafy greens, because it is a component of chlorophyll (remember middle school science).
