In addition to contributing to oxidative stress, a diet high in these foods is linked to obesityso cutting back on these products could also help people maintain a healthy body weight. Goitrogens are substances found in cruciferous vegetables, such as cabbage and Brussels sprouts, and soy products that may interfere with thyroid hormone production.
Most people, including those with hypothyroidism, can enjoy moderate amounts of goitrogenic foods without negatively affecting their thyroid health. Cruciferous vegetables like broccoli are actually quite low in goitrogens. Plus, cooking goitrogenic foods reduces goitrogenic activity, making them safer for people with hypothyroidism.
Other goitrogenic foods include soy and pearl millet. In general, people with hypothyroidism may want to avoid eating large amounts of any goitrogenic foods.
This includes avoiding beverages, foods, and supplements that could interfere with medication absorption. Experts suggest taking thyroid medications like levothyroxine at least 30—60 minutes before breakfast or at least 3—4 hours after dinner.

Women at risk for zinc deficiency include vegans and women with gastrointestinal disorders. Research shows a link between iron-deficiency anemia and decreased thyroid function.
Low iron can prevent iodine from working effectively and also reduce the efficiency of zinc, thus interfering with T4 to T3 conversion and contributing to lower T3 levels. Some researchers have found that when people with iron-deficiency anemia and hypothyroidism improve their iron levels, that may be all that is needed to restore healthy thyroid function.
Women generally need 18 mg of iron per day. The B vitamin complex, especially Vitamin B12, supports thyroid function and thyroid hormone regulation.
In one study , approximately 40 percent of participants with hypothyroidism were also found to be deficient in Vitamin B When administered B12, this group showed improvement in their low thyroid symptoms.
The recommended daily intake for Vitamin B12 is 2. There is no upper limit set for Vitamin B12, as no toxic level has been found. Because Vitamin B12 primarily comes from animal sources, vegans may be at higher risk for deficiency.
Hops are the green cone-shaped flowers of the Humulus lupulus plant. Yes, these are the same hops used in brewing beer. However, hops can play a surprising role in your thyroid health. Specifically, flavonoid molecules in hops help thyroid hormones work better in the body.
A specific flavonoid in hops — xanthohumol — helps iodide uptake by thyroid cells, boosting thyroid hormone production. Hops also have anti-inflammatory properties that protect thyroid tissue from inflammation and oxidative stress. There is no RDA for hops, but researchers have found that up to mg daily is safe.
Yes, you can get hops from drinking beer, but beer is also brewed with wheat — and gluten in the wheat can harm thyroid function, especially if you have a known gluten sensitivity. Your best bet is to stick with hops in supplement form. Ashwagandha has been used for centuries as a natural health remedy, but in more recent years has received attention from medical researchers for its promising effects on thyroid health.
According to preliminary studies, ashwagandha may improve thyroid levels in those with subclinical hypothyroidism.
In one study, participants received a treatment of mg of ashwagandha root daily for eight weeks. At the end of the treatment, serum TSH and T4 levels were significantly improved in the ashwagandha group compared to the placebo group.
Another study from found that ashwagandha improved thyroid hormone levels and reduced thyroid symptoms in patients with both bipolar disorder and hypothyroidism. Researchers speculate that ashwagandha calms overactive stress hormones that can interfere with thyroid hormone production.
One caveat about ashwagandha: consult your doctor if you know or suspect that you may have hyperthyroidism overactive thyroid as excessive use of the herb may worsen hyperthyroid symptoms. Coleus forskohlii is a plant native to India used in traditional Ayurvedic medicine to treat various diseases including underactive thyroid.
Studies about the herb are encouraging. In the body, Coleus forskohlii acts as an adaptogen by encouraging production of T4 and T3 thyroid hormones when levels are too low. Coleus forskohlii also helps to increase basal baseline metabolism, helping the body to burn more calories by increasing lipolysis.
This is a significant benefit for women experiencing low thyroid weight gain. Naturopathic doctors generally recommend between mg a day of Coleus forskohlii when low thyroid symptoms appear.
Bacopa monnieri, also called brahmi, is another traditional Ayurvedic herb used to treat low thyroid. Animal studies have found that Bacopa increased thyroid hormone production by as much as 41 percent when taken daily. In this study, mice were given a mg dose of the herb.
Bacopa is often used in combination with other herbs. For some people, Bacopa may cause side effects including nausea and diarrhea. T-Balance Plus , our exclusive formula for low thyroid support contains Bacopa, Coleus, along with other beneficial nutrients. Research is beginning to turn up other natural compounds that are helpful treatments for low thyroid.
These include:. High levels of stress hormones can harm the thyroid. The amino acid L-theanine helps to reduce stress response activity in the body, balancing stress hormones and helping to protect thyroid function.
Vitamin D helps to regulate the immune system and lowers inflammation. Understanding the type of disorder you have is also essential.
The following groups of people may not benefit from supplements:. Combination thyroid supplements: There are many supplements marketed to support thyroid health that combine a variety of vitamins and minerals and sometimes herbs and other ingredients.
There is no research to support combining multiple nutrients, and, in many cases, more is not better. Vitamin B Research on the relationship between vitamin B12 and thyroid health is conflicting. Some studies suggest that people with hypothyroid are more likely to be deficient in B12 whereas others suggest no relationship.
More research is needed to understand if supplements can support thyroid health. If you have a known B12 deficiency, talk to a healthcare provider about a supplement to support repletion.
To better understand if you should be supplementing with B12, and, if so, which supplements to choose, take a look at our article covering the best B12 supplements. Inositol: Inositol is a precursor to a messenger that helps produce thyroid stimulating hormone TSH.
Preliminary research suggests that inositol also known as MYO-inositol supplements may improve TSH and thyroid antibody levels.
However, more research is needed to understand the safety and efficacy of supplementing with inositol in relation to thyroid health as well as proper dosing. Our team works hard to be transparent about why we recommend certain supplements; you can read more about our dietary supplement methodology here.
We support supplements that are evidence-based and rooted in science. We value certain product attributes that we find to be associated with the highest quality products. It's important to note that the FDA does not review dietary supplements for safety and effectiveness before they go to market.
Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend. We interviewed the following experts to get thyroid supplement recommendations:.
Jillian Greaves, MPH, RD, LDN. Melissa Groves Azzaro, RDN, LD. Supplements that are third-party tested are sent to a lab where they are tested to ensure they contain what they say they contain and are not contaminated with specific high-risk, common contaminants. Most vitamin and mineral supplements come in a variety of forms.
In some cases, such as vitamin D, there is one form D3 that is recommended. In other cases, such as iron, the best form for you may depend on your specific goals and health status.
We reviewed top forms within each supplement recommendation, but we recommend discussing the best form of each supplement with a healthcare provider. It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included, relative to the recommended daily value of that ingredient.
Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking.
Some thyroid supporting nutrients like selenium, zinc, and iodine are combined with other vitamins, minerals, and herbs. Some iron supplements also contain vitamin C, as vitamin C aids the absorption of iron.
Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs and to understand which dosage to take. Each supplement discussed in this article has a different RDA. Please review those amounts discussed within each of the individual supplement recommendations.
Some nutrients, such as vitamin D, can be stored in fat tissue and can be dangerous when consumed in excess through supplementation. Minerals such as iron, iodine, selenium, and zinc can also lead to serious side effects if consumed in excess.
Over-supplementing with nutrients like iodine, selenium, or iron can be harmful and make thyroid issues worse. Whether individual supplement or a combination product like a multivitamin, you can ensure that your supplement does not exceed those upper limits by running your supplement by a healthcare provider.
For example, levothyroxine is a common medication used to treat hypothyroid, and iron supplements are known to interfere with effectiveness of this medication. If you are taking thyroid medication, always check with a healthcare provider before starting any supplements and to create the best plan for when to take them.
Biotin is found in many supplements including B-complex supplements , prenatals, multivitamins, and supplements marketed to support hair, skin, and nails. It may also be found in combination with collagen powders or other collagen supplements.
The safety of thyroid supplements depends on the type of supplement, the dose, and the individual taking the supplement. Thyroid health is largely dependent on lifestyle, and a lot can be done to support your thyroid before considering supplements.
Start by ensuring you are getting adequate sleep and managing stress. Diet and exercise also play an important role. For example, low-calorie diets or diets that eliminate entire food groups can make it hard to meet your nutritional needs and support thyroid health.

According to data from the U. Pasta is not a source of iodine unless it is prepared in water containing iodized salt because it absorbs some of the iodine [ 11 ].
Most fruits and vegetables are poor sources of iodine, and the amounts they contain are affected by the iodine content of the soil, fertilizer use, and irrigation practices [ 2 , 10 ]. This variability affects the iodine content of meat and animal products because of its impact on the iodine content of foods that the animals consume [ 14 ].
The iodine amounts in different seaweed species also vary greatly. For these reasons, the values for the foods listed in Table 2 are approximate but can be used as a guide for estimating iodine intakes. The U. Food and Drug Administration FDA developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet.
The DV for iodine is mcg for adults and children age 4 years and older [ 12 ]. FDA does not require food labels to list iodine content unless iodine has been added to the food. Products made without these conditioners contain very little iodine.
The USDA, FDA and Office of Dietary Supplements-National Institutes of Health ODS-NIH Database for the Iodine Content of Common Foods [ 8 ] lists the iodine content of numerous foods and beverages. The United States, Canada, and dozens of other countries have salt-iodization programs [ 3 , 16 , 17 ].
In the United States, salt manufacturers have been adding iodine to table salt since the s, although this practice is still voluntary [ 18 ]. FDA has approved the use of potassium iodide and cuprous iodide for salt iodization [ 19 ], whereas the WHO recommends the use of potassium iodate due to its greater stability, particularly in warm, damp, or tropical climates [ 3 ].
However, most salt intake in the United States comes from processed foods, and food manufacturers almost always use noniodized salt in these foods.
If they do use iodized salt, they must list the salt as iodized in the ingredient list on the food label [ 9 ]. Specialty salts, such as sea salt, kosher salt, Himalayan salt, and fleur de sel, are not usually iodized. Product labels will indicate if the salt is iodized or provides iodide.
As shown in Table 2, noniodized sea salt provides virtually no iodine [ 8 ]. In dietary supplements, iodine is often present as potassium iodide or sodium iodide [ 20 ]. Supplements containing kelp, a seaweed that contains iodine, are also available. A small study found that people absorb potassium iodide almost completely Dietary supplements containing only iodine are also available, and many contain high doses, sometimes above the UL [ 20 ].
Many dietary supplements that contain iodine are listed in the Dietary Supplement Label Database from the NIH [ 20 ]. This database contains label information from tens of thousands of dietary supplement products on the U. The Total Diet Study TDS , an FDA monitoring program, provides estimated iodine intakes of the U.
population [ 23 ]. Through the TDS program, foods that represent the average U. diet are purchased and analyzed for several components, including iodine. These intakes meet or exceed the EAR for all groups. TDS data do not include iodine that people obtain from the discretionary use of iodized salt [ 25 , 26 ].
Because many U. households use iodized salt, TDS data likely underestimate the true iodine intake of most U. Iodine status is typically assessed using urinary iodine measurements. Spot urine iodine measurements are a useful indicator of iodine status within populations [ 28 , 29 ].
However, multiple hour urinary iodine or multiple spot urine measurements are more accurate for individuals [ 4 , 30 ]. Median urinary iodine concentrations, from spot samples collected as part of a large survey, can be used to characterize the iodine status of populations [ 31 ].
However, because spot samples are not a suitable indicator of individual iodine status [ 30 ], these measurements cannot be used to diagnose individual cases of iodine deficiency or to identify the proportion of a population with iodine deficiency or with excessive iodine intakes [ 31 ].
Urinary iodine measurements from NHANES have been used since to monitor the iodine status of the U. population [ 32 ]. Since the inception of the NHANES monitoring program, urinary iodine measurements have shown that the general U. population is iodine sufficient.
Much of this decline was a result of decreased levels of iodine in milk due to the reduced use of iodine-containing feed supplements and iodophor sanitizing agents in the dairy industry [ 34 ] as well as the reduced use of iodate dough conditioners by commercial bakers.
The use of erythrosine, an iodine-containing food dye commonly used in fruit-flavored breakfast cereals, also decreased during this time [ 34 ] though it is unclear to what extent this change actually affected urinary iodine levels because the bioavailability of iodine from erythrosine has been found to be low [ 35 ].
This sharp decline in urinary iodine levels caused some concern during the late s that the iodine sufficiency of the U. population could be at risk if this trend continued [ 33 ].
More recent NHANES measurements indicate that urinary iodine levels have stabilized in the general U. These values have essentially remained unchanged in the last three NHANES surveys, indicating that the dietary iodine intake of the general U.
population has remained stable since [ 36 ]. Analyses of NHANES datasets from to indicate that a substantial portion of pregnant women in the United States are iodine insufficient.
Suboptimal iodine status during pregnancy has also been observed in Australia [ 39 ]. Pregnant women who do not consume dairy products may be particularly at risk of iodine insufficiency. Overall, it appears that the general U. population has adequate iodine intake but that some pregnant women may be at risk for iodine deficiency.
Continued national iodine monitoring is needed with more emphasis on population subgroups that are most susceptible to iodine deficiency disorders.
Iodine deficiency has multiple adverse effects on growth and development and is the most common cause of preventable intellectual disability in the world [ 41 ]. Iodine deficiency disorders result from inadequate thyroid hormone production secondary to insufficient iodine [ 5 ].
During pregnancy and early infancy, iodine deficiency can cause irreversible effects. Under normal conditions, the body tightly controls thyroid hormone concentrations via TSH.
TSH increases thyroidal iodine uptake from the blood and the production of thyroid hormone. However, very low iodine intakes can reduce thyroid hormone production even in the presence of elevated TSH levels. Goiter is usually the earliest clinical sign of iodine deficiency [ 2 ]. In pregnant women, iodine deficiency of this magnitude can cause major neurodevelopmental deficits and growth retardation in the fetus as well as miscarriage and stillbirth [ 5 ].
Chronic, severe iodine deficiency in utero causes cretinism, a condition characterized by intellectual disability, deaf mutism, motor spasticity, stunted growth, delayed sexual maturation, and other physical and neurological abnormalities [ 5 ].
These have antioxidant properties that help to break down peroxides, which can damage tissues and DNA, leading to inflammation and other health problems. Another Cochrane review of 83 randomized placebo-controlled trials did not find that selenium supplementation reduced the risk of any cancer type.
In addition, some of the trials noted a higher incidence of type 2 diabetes with long-term use of selenium supplements about 7 years who had normal selenium blood levels at the start the of study. Further research is needed to replicate this finding.
Additional research is needed on the association of selenium and cancer before making specific dietary recommendations. There are high concentrations of selenium in the thyroid gland, where there are several selenium-containing enzymes regulating thyroid function.
Both of these conditions cause the body to create antibodies that attack the thyroid gland, leading to an overactive thyroid hyperthyroidism or underactive thyroid hypothyroidism. Randomized controlled trials studying selenium supplementation show mixed results.
Supplements have not been shown to significantly affect thyroid function in people with normal thyroid or mild hypothyroidism, despite causing increased blood levels of selenium. The role of selenium supplementations for people with autoimmune thyroid diseases ATD is still unclear. A systematic review and meta-analysis of nine controlled trials did not find that selenium supplements changed thyroid hormone function in people with ATD, nor did a Cochrane review.
Selenoproteins help to protect cell membranes from damage by free radicals and keep blood platelets from becoming sticky, both of which can lead to heart disease. However, both cohort studies and clinical trials have shown mixed results regarding the relationship of selenium and cardiovascular disease CVD.
Observational studies have shown that people with both low and high selenium exposure based on dietary intake and blood levels have an increased risk of CVD.
Others have found no association at all. Additional research is needed on the association of selenium and CVD before making specific dietary recommendations.
The amount of selenium in foods can vary widely depending on the selenium content of the soil in which it is grown. Soil content varies widely by region. Plant foods obtain selenium from soil, which will then affect the amount of selenium in animals eating those plants.
Protein foods from animals are generally good sources of selenium. Vitamin A works with other nutrients like zinc to convert inactive to active thyroid hormone. A study on women who supplemented with vitamin A found that it lowered TSH and could help with subclinical hypothyroidism. Another study concluded that vitamin A can support healthy thyroid function.
Lower levels of vitamin A can adversely impact the thyroid gland and lead to higher TSH. But just like iodine, too much vitamin A could suppress thyroid function, so more is not better. You can't overdo food sources of vitamin A, but too much from supplements can be toxic in super high amounts so you want to make sure the supplement you take has the right amounts.
Selenium is a big one for thyroid nutrients, and the thyroid gland stores the majority of selenium in the body. It's needed to make active thyroid hormone, so a deficiency means you have less active thyroid hormone and more hypothyroid symptoms. It's also an antioxidant, which helps reduce the impact of oxidative stress that can damage the thyroid gland.
Adequate selenium reduces the risk of autoimmune thyroid, and supplementation supports lower thyroid antibodies.
Some foods like brazil nuts are a rich source of selenium, but the actual amount can vary based on soil content.
Copper is a mineral that's involved in thyroid hormone production and regulation. It helps make T4 and regulates how much is absorbed in the cells. Copper levels must be balanced with zinc, so too much or too little of one can lead to issues with the other.
Thyroid hormone levels can be lower in people with copper deficiency. The best way to get copper is from food, and the RDA is mcg a day. But if you are supplementing with zinc, copper must also be balanced in the correct ratio.
Vitamin D is a hormone involved in over processes in the body, including many related to the thyroid. It can support lower TSH and thyroid antibodies. Low vitamin D levels are common with Hashimoto's and autoimmunity in general and hypothyroid , and many experts consider it a key player in autoimmune conditions.
The best way to get vitamin D is from sun exposure, but since that's not possible year-round or for everyone, supplementation could be helpful, especially in the winter.
Turmeric is a spice that contains curcumin, an active compound with powerful anti-inflammatory and antioxidant effects. Since inflammation is a root cause of many chronic diseases, including thyroid conditions, curcumin can help support autoimmune thyroid health by helping to protect against oxidative damage.
Curcumin has been shown to help reduce the size of thyroid nodules. It also could help support blood pressure , which can be a concern for some people with thyroid conditions. You can get turmeric from supplements or by adding it to food. If you use the spice, make sure to pair it with black pepper to enhance absorption.
Zinc is a mineral needed for thyroid hormone production, including TSH, T3, and T4. It helps regulate the enzymes required to make thyroid hormone and helps convert T4 to T3.
Zinc deficiency is linked to hypothyroidism and Hashimoto's. Zinc deficiency may be part of why thinning hair is a common symptom of hypothyroidism. Like selenium, zinc is a trace mineral, and they work together to support your thyroid. So supplementation with both can help your thyroid function.
As mentioned earlier, zinc levels must be balanced with copper, so too much or too little of one can lead to issues with the other. Iron is a mineral involved in many processes in the body, including thyroid function.
It's needed to make thyroid hormone, and low levels can lead to hypothyroidism. Iron is also required for T4 to T3 conversion.
Anemia is common with hypothyroidism, but anemia can also impair thyroid function, so it's a vicious cycle. The best way to get iron is from food, and the best sources are animal-based foods like red meat, organ meat, and seafood.
When choosing plant-based non-heme iron it is important to combine it with adequate vitamin C foods to enhance absorption, since iron from these sources tend to be less bioavailable. If you are supplementing with iron, make sure to do so under the care of a healthcare professional.
Probiotics are beneficial bacteria that support gut health. Since the gut and thyroid are closely connected, probiotics can be helpful for those with Hashimoto's or other thyroid conditions.
Probiotics can help address intestinal permeability and support autoimmunity. By supporting gut health and intestinal permeability , you can help lower inflammation and improve nutrient availability, both so important for thyroid health and reducing thyroid antibodies.
You can get probiotics from supplements or fermented foods like yogurt, kimchi, sauerkraut, and kombucha. When it comes to supplements of any kind, you want to be careful about what you take and make sure it's high quality.
This is especially important with thyroid supplements. Kitchen sink supplements meaning the company throws in every nutrient you can think of can sometimes contain unsafe ingredients. They may also include glandular dried and powdered animal glands that aren't obvious on the label or can contain contaminants.
Plus, not all forms of iodine, selenium or other nutrients are created equal. They also may contain nutrients that aren't in the correct ratios, and as you just learned, too much isn't always a good thing.
When you purchase a thyroid supplement, make sure you trust the company, and that the ingredients are high quality.

Most Americans have no problem getting enough iodine, since table salt is iodized—but if you're on a low-sodium diet as an increasing number of Americans are for their heart health or follow a vegan diet more on that laterthen you may need to up your iodine intake from other sources. Many types of seaweed are chock-full of iodine, but the amount can vary wildly, Mira Ilic, RDa registered dietician at the Cleveland Clinic, told Health. According to the NIH, the iodine amounts in different seaweed species vary considerably.
