Miss Lizzy Answers

Founder, patient, advocate, wife, and mom, I'm here to answer your questions!

What makes Thiodine different from other iodine products?


When we say you'd have a hard time finding a higher quality iodine supplement, we mean it. We don't cut corners because your health is too important.

Quality Standards

Think of it this way. The term "iodine" is much like the term "coffee." It might sound like coffee is all the same, but it's simply not true. What makes Starbucks different from your local coffee shop, Dunkin Donuts, or Folgers? The source, sustainability, manufacturing, roasting, and farming practices. The same is true for iodine. 

Iodine grades range from something you might use in a chemistry lab or an aquarium to prescription-grade iodine for human use. 

Mining Standards

Our Geologist explains it this way. When it comes to iodine mining and sustainability, there are different methods, grades, and quality standards. Outside of China, one of the largest producers of iodine is the Caliche mines in South America. Caliche iodine is often referred to as "Dirty Iodine" because the iodine does not meet USP Grade. In terms of sustainability, the Caliche mining method uses explosives to blast large areas of the Earth's crust and "scrape" the blasted material.

Manufacturing Standards

Just like in food production, there are licensing and quality standards. That's how you know it's safe to eat at your local restaurant. The FDA helps assure the identity, strength, quality, and purity through cGMP manufacturing of dietary supplements.


CGMP stands for Current Good Manufacturing Practice, which assures you of control manufacturing operations including quality management systems, obtaining appropriate quality raw materials, establishing robust operating procedures, detecting and investigating product quality deviations, and maintaining reliable testing laboratories,

That's why ingredients, sustainability, sourcing, manufacturing, state & local compliance, and certified quality set us apart. We can proudly and confidently say Thiodine is:


  • Made under CGMP in the USA
  • Certified USP Grade, 99. 8% Pure
  • Rigorously Tested
  • Sustainably-sourced from deep Earth USA mines
  • Encoded with LOT # and Expiration Date for safety, traceability, and accountability
  • Licensed & Insured
  • Compliant with federal, state, and local regulation

Is Thiodine suitable for dietary or iodine allergies?


Iodine is a vital nutrient utilized by every cell in the body. Thiodine has no wheat, dairy, corn, soy, sugar, sucrose, eggs, nuts, animal products, pesticides, harmful chemicals, artificial colors, preservatives, sweeteners, or sugar. It's also non-GMO. Thiodine is suitable for any diet, including Paleo, keto, and vegan-friendly. It's even iodine-allergy friendly. 

 *We always suggest consulting a medical professional.


How do I use Thiodine liquid?


Thiodine may boost energy so some people prefer to use it in the morning. Thiodine should always be diluted. Avoid mixing Thiodine with citrus or Vitamin C since the ascorbic acid may interfere with the iodine. The suggested serving size is 2 small drops in 8 ounces of non-citrus juice, coffee, or tea. Some people use more, others use less. The amount of iodine varies by individual.

CAUTION: Please don't put Thiodine directly in your mouth or on skin. Thiodine should always be diluted.


What are ingredients and suggested dose?


Thiodine contains potassium iodide, molecular iodine, and distilled water. The suggested serving is 2 small drops, each servings contains approximately 10 MG of potassium iodide of which 7.5 MG is the iodide component and 5 MG of molecular iodine, for a total of approximately 12.5 MG of iodine per serving. 

Each 1 oz bottle contains approximately 300 servings and lasts anywhere from 4-10 months or longer depending on use. To dispense, hold the dropper straight down, not at an angle. Please note: a drop means a single drop, not a dropper full.

Thiodine comes from earth mined iodine crytals in the USA. Our exclusive source of iodine is the highest quality, potency and purity in a USP grade supplement.

CAUTION: Never put Thiodine directly in the mouth or on skin undiluted. Thiodine is meant to be diluted as explained in the suggested use.


Can I use Thiodine with other thyroid medication?


The primary role of the thyroid gland is to help make thyroid hormones. These thyroid hormones are called T4 and T3, and they play a vital role in your energy, metabolism, immune function, reproductive health, and more.

When the thyroid gland isn't producing enough of these thyroid hormones, you may develop a condition called Hypothyroidism or experience symptoms including:

- Low body temperature 

- Feeling cold 

- Fatigue, exhaustion, low energy even with plenty of sleep

- Hormone imbalances

- Infertility

- Dry hair, skin, and nails,

- Weight gain

- Thyroid goiter or nodules

Your doctor may prescribe thyroid hormone replacement medication.

However, it's essential to understand how thyroid hormone production works.

The body requires certain minerals to make thyroid hormones -- iodine and selenium. Iodine helps the thyroid make thyroid hormones (mostly T4 and a little T3), and selenium helps convert T4 into T3 for energy.

Like with a car, you need the right kind of fuel in the tank, a key to start the engine, and filters to remove impurities.

If any or all of these systems fail, you may not feel great.

For example, a person might not be getting enough T4 for fuel, which may leave them with Hypothyroid symptoms. 

A person might be getting plenty of T4 thyroid hormones, but if their body can't effectively convert T4 into T3, it would be like stepping on a gas pedal while your car is park. You'd flood the engine. 

A person might have filtration issues, meaning bromine and fluoride clog the thyroid cell receptors (and other tissues), blocking thyroid hormone production. Thyroid medication might help compensate for some of what the thyroid can't do on its own due to these endocrine disruptors. But it won't dislodge bromine and fluoride because thyroid medication is not a halide like iodine. 

As you can see, iodine and selenium levels play a vital role in supporting thyroid function. 

Our supplements are formulated to help with these three essential processes. 

- Thiodine provides the fuel

- Thiosel provides the key

- Thiosalt helps provides the filtration

People may find they need a combination of thyroid medication and supplements to support thyroid function, but everyone is different.

That's we always recommend working with a medical practitioner and discussing before taking this or any supplement.


What if I don't have a thyroid?

Most people know that the thyroid gland needs iodine, and while that's true, many don't know that every cell in the body needs iodine. That's trillions of cells. So if you're not getting iodine because you don't have a thyroid, it's essential to understand all the many processes that rely on this vital nutrient. 

However, many people don't realize there are two types of iodine -- molecular iodine and potassium iodide -- each reaches different tissues in the body. 

Potassium iodide travels through the NIS pathways to support the thyroid, hair, skin, and nails. 

If you don't have a thyroid, it's true, supplements with potassium iodide will not be of much help. They may still have a benefit for the hair and skin.

However, molecular iodine travels to tissues in the breasts, ovaries, brain, pineal gland, pancreas, eyes, and other tissues that Potassium Iodide cannot reach. 

That's why understanding the type of iodine is essential and supporting all the cells in the body, not just the thyroid.

For people who don't have a thyroid, the conversion of thyroid hormone T4 into the active T3 -- which happens primarily in the liver -- is another critical factor. Like having a gas tank fuel of full, you need a key to start the car.

Whether your body naturally makes thyroid hormones or gets them from medication, the body needs certain nutrients, specifically, adequate selenium, to help convert those hormones.

Learn how Thiosel is formulated to support conversion.

Can I take Thiodine if I have a goiter or nodule?

According to the American Thyroid Association, iodine deficiency in the diet leads to goiter, thyroid nodules, and hypothyroidism† (11). Iodine Deficiency Disorder affects up to 2 billion people worldwide. (11) 

The research suggests iodine supplementation in the diet may help reduce goiter and nodules (11), so that could be great news for some.

However, there are some instances where iodine may not be appropriate, such as a thyroid condition called an "Autonomous Thyroid Nodule" or a "Hot Nodule."

According to the research, an autonomous thyroid nodule is a localized nodular lesion of the thyroid, detected through a proper medical examination. An autonomous thyroid nodule is rare in the USA and appears linked to childhood iodine deficiency. 

According to experts, the growth, iodine uptake, and function of an autonomous thyroid nodule are independent of TSH control. Meaning, it's kind of a rogue nodule that does what it wants and doesn't know when to stop. (14) 

Unlike a "regular thyroid nodule" that uses iodine to make amounts of thyroid hormones and self-regulates, an autonomous thyroid nodule can't effectively regulate iodine intake, which may result in a flood of thyroid hormones. 

Luckily, as mentioned, an autonomous thyroid nodule is rare in the USA. But all the more reason to talk with your doctor and make sure you don't have an autonomous thyroid nodule before starting iodine.

I have Hashimoto's and was told not to use Iodine


Frequently Hashimoto's patients have heard iodine supplementation is dangerous, and they should avoid it at all costs, but that's simply not true. 

When used correctly with the right nutrients and a knowledgeable medical practitioner's help, iodine supplementation may be an essential element of the Hashimoto patient's tool kit. 

A vital issue for Hashimoto's patients is appropriately supporting the thyroid during conversion, protecting from oxidative damage. Our bodies need to make thyroid hormones for energy, just like a key that starts your car. 

According to Chen et al. (2007), scientists found that extra selenium allowed the subjects to consume higher doses of iodine without altering the immune parameters. (15) As a result, patients received the benefits of iodine without oxidative damage. (16)

Selenium levels play a vital role in thyroid hormone conversion, helping convert the inactive T4 thyroid hormone into the active T3 hormone.

According to a top British Doctor, Marek Doyle, iodine is safe, beneficial, and often necessary to rebalance Hashimoto's thyroid function when used in the right way. (17)

The research suggests a physiological dose (100 mcg-400 mcg) of selenium in the form of selenomethionine (Thiosel) may help support the thyroid during conversion, increase serum selenium levels with a reduced risk of selenium toxicity. 


Do I get enough iodine from iodized salt?

It might be a surprise to learn that iodized salt is not a great source of iodine. But three common misconceptions about salt and iodine might surprise you even more. 

1. Most salt is not iodized

2. Salt this iodized contains only potassium iodide

3. Iodized salt loses a lot of the iodide by the time it reaches your home

There's even more to the story about processed salt (which is actually cheaply manufactured) and the health risks.

Read the whole story about iodized salt. 

What is Iodine "Stockpiling"?

When starting a high potency iodine supplement like Thiodine, some people may experience tightness or a swelling sensation in the thyroid area of the throat. It may a short-term issue we call "stockpiling."

If the thyroid has been deficient in iodine (in some cases for a long time), and you start a high potency supplement like Thiodine, the thyroid may "overindulge" on iodine. 

While stockpiling is not a clinical term, it gives you an idea of what might when the thyroid gets excited about the new iodine and tries to save it for future use. 

Similar to if you were very hungry and went to a buffet, you might have a hard time resisting all the food. As a result you might over-eat and feel stuffed. The thyroid gland can overindulge, too. Similar to digestion, the stockpile of iodine may naturally work itself out.

The thyroid requires iodine to make thyroid hormones. Under normal conditions, the thyroid gland can have as much as 15 MG of iodine, and that's not counting the rest of this body -- ovaries have the next highest concentration. So iodine is essential for the entire body. But the thyroid is first in line at the buffet.

If the thyroid is Stockpiling, once it realizes it doesn't need to eat a week's worth of iodine in one sitting, it will release the iodine to the rest of the body. 

So a swelling sensation or tightness in the thyroid area of the throat that occurs after starting iodine supplementation might be Stockpiling. But it could be something else, so if the sensation persists or you are concerned at all, please always consult a medical practitioner (ideally one who specializes in iodine).

Is Thiosel suitable for Hashimoto's?


According to research and patient experience, selenium may be a vital nutrient for people with Hashimoto's especially when supplementing with an iodine supplement like Thiodine. Selenium plays a role in thyroid hormone creation because it helps protects the thyroid from oxidative damage, as well as convert thyroid hormones into energy. 

Some experts recommend taking a physiological dose of selenium (as selenomethionine) of 100 mcg- 400 mcg/day. Of course we always recommend working with a medical practioner and doing what's right you.

For those with Hashimoto's and the MTHFR continue to the next question for more information.


Can I take Thiosel if I have MTHFR Gene C667 and A1298


With genetics testing through sites like 23andme and books like "Dirty Genes," MTHFR and methylation are big topics these days. Especially in the thyroid and Hashimoto's communities. In simple terms, some people with markers for the MTHFR C667T and A1298C have reported issues in methylation or "breaking things down for use or removal." (5) 

When the MTHFR genes are working correctly, the body can break down minerals for use and removal more effectively. When the MTHFR genes are not working effectively, some people might experience high iron levels with low ferritin, high levels of B12, folate, and selenium. 

MTHFR can be a complex topic, so it is especially important to work with a medical professional who has experience in genetics and MTHFR. 

Recently we learned my husband has the MTHFR C667 and A1298. So we had his homocysteine and selenium levels tested and discovered they were relatively high. For this reason, he is careful about supplementing with selenium until he can talk with his doctor about MTHFR and methylation. As a customer, I think of you as someone in my family. I want to research and information so you can make informed choices for your health.


Can I get selenium from brazil nuts and food?


The amount of selenium in brazil nuts and other foods can vary a lot based on the soil nutrients, just like the Goiter Belt's low levels of iodine. In other countries where Brazil nuts are grown, the selenium content of the soil and farming conditions can vary quite a lot. For this reason, food sources may be unreliable sources of selenium. When it comes to health issues like Hashimoto's and Hypothyroidism, "in-range" selenium levels seem to play a significant role. Personally, and for my family, I want to be precise about my selenium intake.†


Are there risks in consuming too much selenium?


Yes. Like anything in life and health, the key is finding what's "just right" for your unique needs. At doses greater than 900 mcg/day and chronically high intake, selenium toxicity is possible. Selenium toxicity symptoms may include gastrointestinal upset, tremors, dermatitis, fatigue, irritability, garlic odor of the breath, abnormal nails, hair loss, and peripheral neuropathy. Treatment of high levels of selenium may involve reducing selenium consumption. (6,7). It's my hope to help you find answers, not create problems. So please always consult a medical practioner.


Is there a test for selenium levels?


There are a couple of options for selenium testing. First is the RBC test, which measures serum selenium levels in the blood. Typically the RBC is ordered through a doctor's office and may be covered by insurance. According to patient groups, the ideal selenium level will be at the upper end of the lab's reference range. If selenium levels are mid to low within the range, selenium supplementation may be beneficial. Another popular method for testing mineral levels, including selenium, is through Hair Tissue Mineral Analysis. While insurance may not cover HTMA, a skilled practitioner may be able to provide mineral analysis for your unique situation. Again, please consult your doctor. This information is not meant as advice and should never replace the advice of your doctor.


Are there any interactions with other supplements or medications?


We are not aware of interactions but interactions please consult your doctor before taking this or any supplement.
