Your thyroid gland plays a vital role in regulating your body’s metabolism, energy levels, and overall health. When it’s not functioning properly, you can experience symptoms like fatigue, weight gain, and brain fog.

That’s where supplements to support your thyroid can come in. They provide your body with the nutrients it needs to support optimal thyroid function.

But with so many options out there, how do you know which supplements are the best? We’ve done the research for you and compiled a list of the top thyroid supplements recommended by experts in the field.

What is the Thyroid?

The thyroid gland is a butterfly-shaped organ located in the neck. It’s part of the endocrine system, which produces hormones that regulate various functions throughout the body. The thyroid gland produces two main hormones, triiodothyronine (T3) and thyroxine (T4), which are essential for regulating metabolism, body temperature, and energy levels.

The thyroid gland is controlled by the pituitary gland in your brain, which tells it when to produce hormones. If the thyroid gland produces too few hormones, you may experience hypothyroidism, which can cause symptoms like fatigue and weight gain. If it produces too many hormones, you may experience hyperthyroidism, which can cause symptoms like weight loss and anxiety.

Fortunately, there are ways to support thyroid function and promote optimal health. Along with a healthy diet and lifestyle, certain supplements can provide your body with the nutrients it needs to support thyroid function and reduce symptoms of thyroid dysfunction.

How Do Thyroid Supplements Work?

Thyroid supplements work by providing the body with essential vitamins, minerals, and nutrients necessary for optimal thyroid function. These supplements can help address any nutrient deficiencies and support overall thyroid health.

Certain nutrients are commonly low in people with hypothyroidism, including selenium, zinc, and iodine. Supplementing with these nutrients can help regulate thyroid function and support the production of thyroid hormones.

In addition to supporting thyroid function directly, some supplements can also promote gut health, which plays a significant role in thyroid function. Supplements like probiotics and digestive enzymes can help reduce inflammation and improve gut bacteria balance, thereby improving thyroid function.

It’s important to note that while supplements can be beneficial, they are not intended to treat or cure medical conditions. They work best as part of a holistic approach to thyroid health that includes thyroid medication (when necessary), diet, stress reduction, and sleep. Consulting with a healthcare professional before starting any supplement regimen is also recommended.

Benefits of Thyroid Supplements

Boost Energy Levels and Metabolism

One of the main benefits of thyroid supplements is their ability to improve energy levels and metabolism. Your thyroid gland plays a crucial role in regulating your body’s metabolism, and when it’s not functioning optimally, you may experience fatigue and sluggishness.

Studies have shown that thyroid supplements containing iodine, selenium, and zinc can help support healthy thyroid function and improve energy levels [1]. In addition, some supplements may also contain herbs like ashwagandha, which has been shown to reduce stress and increase energy levels [2].

With improved energy and metabolism, you can take on the day feeling more alert and focused.

Support Mood and Emotional Wellbeing

Another benefit of thyroid supplements is their ability to support mood and emotional well-being. Research has shown that individuals with hypothyroidism are at a higher risk for depression and anxiety [3].

Thyroid supplements containing selenium and ashwagandha have been shown to help reduce symptoms of anxiety and depression, as well as improve the overall quality of life [4].

By taking thyroid supplements, you may be able to improve your mood and emotional well-being, leading to a happier, more fulfilling life.

Aid in Weight Loss

Thyroid supplements may also be beneficial for those looking to lose weight. Hypothyroidism can lead to weight gain and difficulty losing weight, but by supporting healthy thyroid function with supplements, you may be able to improve your body’s ability to burn fat and lose weight [5].

Supplements containing iodine and selenium have been shown to improve metabolic rate, while ashwagandha may help reduce stress-related weight gain [6]. By combining thyroid supplements with a healthy diet and exercise routine, you may be able to achieve your weight loss goals more effectively.

Promote General Health

Finally, taking thyroid supplements can help improve your overall health and well-being.

The thyroid gland plays a crucial role in regulating many bodily functions, and by supporting its function with supplements, you may be able to reduce your risk of developing certain health conditions. For example, low thyroid function has been linked to an increased risk of heart disease and cognitive decline [7].

You may be able to reduce your risk of developing these and other health issues, leading to a healthier, happier life with the help of thyroid supplements.

Now that we have a better understanding of the thyroid, here are the top natural thyroid-supporting supplements currently on the market.

1) Iodine

Check Lowest Price

Iodine is an essential mineral that is necessary for the production of thyroid hormones. These hormones play a crucial role in regulating metabolism, growth, and development. When the body doesn’t get enough iodine, it can lead to an enlarged thyroid gland (known as a goiter) and an underactive thyroid gland (known as hypothyroidism).

It’s important to note that iodine supplementation may not be necessary for everyone. In areas where iodine is naturally present in the soil or added to salt, most individuals get enough iodine from their diet.

Additionally, some individuals with thyroid conditions may actually be sensitive to iodine and may need to limit their intake.

The recommended daily allowance (RDA) of iodine varies depending on age and stage of life. For adults, the RDA is 150 micrograms (mcg) per day.

Pure encapsulations iodine is an excellent option if you’re looking to incorporate this into your daily routine.

2) Magnesium

Thorne Magnesium Bisglycinate

Check Lowest Price

Magnesium is an essential mineral that plays a critical role in various bodily functions, including thyroid health. Magnesium is required for the conversion of the inactive thyroid hormone T4 to the active form T3. Without sufficient magnesium, the body may not be able to produce enough T3, leading to hypothyroidism.

Additionally, magnesium plays a crucial role in managing stress, which is a common trigger for thyroid imbalances.

Stress can cause the body to release cortisol, a hormone that can interfere with the proper functioning of the thyroid gland. Magnesium can help reduce cortisol levels and promote relaxation, reducing the impact of stress on the body and supporting overall thyroid health.

If you’re considering magnesium supplementation, Thorne Magnesium bis-glycinate powder is a perfect place to start. For more options and details on which forms of magnesium or the best, check out our article on the best magnesium supplements.

3) Vitamin D

Performance Lab D3 + K2

Check Lowest Price

Vitamin D plays a crucial role in thyroid function. It helps regulate the production and conversion of thyroid hormones, and a deficiency in vitamin D3 can lead to thyroid imbalances. Research shows that low vitamin D3 levels are associated with an increased risk of autoimmune thyroid disorders such as Hashimoto’s thyroiditis.

Vitamin D also helps support immune function, which is essential for overall thyroid health. A compromised immune system can increase the risk of thyroid problems, and vitamin D3 can help support immune function to reduce this risk.

It also pairs well with vitamin k2, which is why we recommend this D3+K2 supplement from Performance Lab.

4) Selenium

Check Lowest Price

Selenium is crucial for thyroid health as it helps produce active thyroid hormones. When deficient, the body produces less active thyroid hormone leading to hypothyroid symptoms. Selenium is also an antioxidant that helps protect the thyroid gland from oxidative stress.

Adequate selenium intake reduces the risk of autoimmune thyroid disorders, and supplementation can lower thyroid antibodies. The RDA for selenium is 55 mcg/day, but some people may benefit from higher doses of 100 to 200 mcg/day.

We loved Upgraded Selenium because it’s made with stabilized nano minerals, which tests for high absorption.

5) Zinc

Thorne, Zinc Picolinate, 15 mg, 60 Capsules

Check Lowest Price

Zinc is an essential mineral required for thyroid hormone production, including TSH, T3, and T4. It helps regulate the enzymes needed for thyroid hormone synthesis and T4 to T3 conversion. Low zinc levels are linked to hypothyroidism and Hashimoto’s, and hair thinning is a common symptom of hypothyroidism due to a deficiency in zinc.

Zinc and selenium work together to support thyroid function, so supplementation with both can be beneficial. However, it’s important to maintain a balanced zinc-to-copper ratio as too much or too little of one can affect the other.

The recommended daily intake of zinc is 8 mg for women and 11mg for men. If taking zinc supplements, it’s crucial to ensure adequate copper intake as well.

6) Iron

NOW Foods, Iron, 18 mg, 120 Veg Capsules

Check lowest price

Iron is a crucial mineral for various bodily functions, including thyroid health. It’s essential for making thyroid hormones and converting T4 to T3, and low levels can lead to hypothyroidism. Anemia is a common occurrence with hypothyroidism, and it can further impair thyroid function, creating a vicious cycle.

Combining plant-based sources with vitamin C-rich foods enhances the absorption of iron, which is also available from animal-based foods. Women require 18 mg/day of iron, while men require 8mg/day, according to the RDA.

7) Probiotics

Kaged Pro-Biotic

Check Lowest Price

Gut problems are common precursors to out-of-whack thyroid hormone levels. Probiotics are a simple line of defense to support gut health.

The gut is responsible for dictating thousands of processes in the body; hence why is commonly referred to as the second brain. If the gut is off, there can be a whole host of issues ready to arise, and the thyroid is certainly not immune to being affected.

There are a ton of options out there for probiotics. We like Kaged Pro-Biotic because they use a strain specifically designed to support athletic performance.

8) Vitamin B12

Doctor's Best Fully Active B12

Check Lowest Price

B vitamins, but especially B12, are critical for a healthy nervous system, energy levels, and overall general health.

Some research suggests that vitamin B12 deficiency has been linked to Hashimoto’s, due to the higher thyroid antibodies. Don’t be surprised if after you take some B12 you get a nice kick of energy.

9) Curcumin

Doctor's Best, High Absorption Curcumin, 500 mg, 120 Capsules

Check Lowest Price

Curcumin is a powerful antioxidant known for its anti-inflammatory properties to treat common chronic pain issues like osteoarthritis. These anti-inflammatory properties can also play a crucial role to help the fight against autoimmune diseases such as Hashimoto’s.

Supplementing with Curcumin can help reduce the size of thyroid nodules, which are a very common side effect of hypothyroidism.

Tackling inflammation head-on with the active properties found in curcumin is a great natural remedy for addressing the root cause of many chronic diseases. Thorne again has created a really great curcumin product that helps fight off that inflammation.
