Top 24 Nutrients for Optimal Thyroid Function

I have something really important I want to share with you. I’m often asked the kind of nutrients that are helpful for thyroid disease, especially for those already on a healthy diet. That begs the question: are supplements even helpful for thyroid disease? If so, which should you take? How much should you have of each?

After doing the research to help get you an answer, I have 24 nutrients I want to share with you that can help with optimal thyroid function.

I know, 24 might seem like a lot, but it’s important we have a thorough understanding of each. Today, I’ll break them all down for you…

Do You Need Supplements At All?

Here’s a great question: If you are on a healthy diet, do you need supplements in the first place?

The fact is that a healthy diet is essential because pills can never replace real food. Yet, in the data below, I’m going to show you specific benefits to supplemental nutrients.

https://shop.drchristianson.com/products/chocolate-daily-reset-shake

If you do have thyroid disease and are not feeling your best, both diet and supplementation are important. Don’t forget that you’re always supplementing with a healthy diet!

Below, I’ll get into the role that nutrients play in normal thyroid function, as well as the benefits of supplementation with certain nutrients. These are points that are often confused.

It is key that you enjoy a healthy diet with enough nutrients to prevent a deficiency. At the same time, though, supplementing with nutrients can reveal additional benefits beyond just the diet.

Key Insight: Certain key nutrients can have a pharmacological effect on us, which can help, in ways that we can’t through diet alone.

So, let’s get started on reviewing all these great supplemental micronutrients! If you’re able to get all 24, you’re better able to enjoy:

  • Stable thyroid levels
  • Easier thyroid regulation
  • Improved thyroid function
  • Increased energy
  • Better hair and skin
  • Improvement in your mood
  • Better control over memory

Key Insight: That’s because these nutrients work collectively! You want a global improvement in all things relating to your thyroid, so all 24 work better together, as the complete package.

A Deep Dive On Nutrient Testing

For nearly all of the 24 nutrients we’re going to talk about today, there are unfortunately no tests that predict whether or not that nutrient may improve your thyroid function.

In addition, for most, there aren’t even any accurate tests that determine whether or not you are deficient in that nutrient in the first place.

While tests do exist that measure the levels of most nutrients, unfortunately, many of them just are not accurate.

In truth, the concept of nutrient testing has failed to live up to its expectations. It’s not easy to do in real-time, and it’s not predictive in terms of who might benefit.

Daily Reset Packs - Complete Nutrition - Dr. Alan Christianson

While there are a couple of big exceptions, such as:

  • Iron
  • Vitamin D
  • Trace minerals (possibly)

By and large, as appealing as it might sound it’s not really worthwhile. I have seen so many tests that try to do this, but they most often are not worth the effort.

Who Should Test Their Nutrients?

Absolutely anyone can benefit from testing their vitamin D levels. In ng/ml, the ideal vitamin D levels for adults with thyroid disease are 30-50.

Some might recommend higher levels, but this is often based on studies that reference different units that are 2.5 times higher. (Read More: A Full Breakdown On Vitamin D)

Those who are dealing with unexplained fatigue and hair loss might also do well to take a B12, folate, and iron levels test. (Read More: Testing For Your Iron Levels)

Folate and B12 can be tested with serum (blood) tests, and it is possible to be low in these nutrients before your blood levels even get below range.

If your levels are well above mid-range, you are not likely deficient. The same applies for a variety of B vitamins, too.

We also need to think about some minerals. This might include:

  • Magnesium
  • Calcium
  • Selenium

In some cases, using red blood cell tests, you may be able to figure out if you are lacking in any of these important minerals.

The last one worth mentioning is checking for serum levels of zinc in the body. It’s not the most perfect indicator, but it can show up if someone has unusual losses.

The Top 24 Nutrients To Help Your Thyroid

thyroid vitamins

These are the 24 things that are important and documented to be relevant for thyroid function. Let me take you through each of them, as well as the data behind them…

1. Vitamin A

In terms of its importance to thyroid function, vitamin A is known to be essential for the regulation of genes that control how the body responds to your TSH.

A large subset of those with thyroid disease may be unable to convert dietary carotenoids into active forms of vitamin A (like retinoic acid).

Vitamin A: The Evidence

In one recent study, 84 women between the ages of 17-50 were randomized to receive vitamin A supplements or a placebo1.

They were divided into three groups:

  1. OA – Overweight women given vitamin A
  2. OP – Overweight women given a placebo
  3. N – Non-overweight women given vitamin A

Over a period of four months, those receiving vitamin A supplements had a statistically significant improvement in their thyroid function.

In fact, their TSH scores lowered by roughly one full point, while their T3 levels elevated (roughly) by one full point, as well.

The chart below illustrates those results:

Vitamin A: How Should You Supplement It?

The best form of vitamin A in supplements is a combination of mixed carotenoids and palmitate.

Key Insight: The most useful amount, in coordination with a healthy diet, is 300 – 350 retinoic acid equivalent units — or, roughly 30% of the recommended daily value.

Keep in mind, though, that because vitamin A is fat-soluble, higher doses should definitely be avoided.

2. Vitamin C

We consider vitamin C important because of its ability to prevent damage to the thyroid cells from autoimmune disease.

It is also helpful because it aids selenium in its role of regulating iodine and thyroid hormones2.

Vitamin C: The Evidence

Many of those who take thyroid medications do not end up with consistent absorption of the active ingredients.

This problem ultimately leads to unresolved symptoms, such as fatigue or weight gain. It can also cause blood levels to be erratic.

In one recent study, 31 patients were selected who were on treatment for hypothyroidism but were unable to achieve stable blood levels.

After receiving low-dose vitamin C supplementation, their TSH levels improved by 69.2%, and serum T3 and T4 significantly improved, too.

Researchers concluded that:

“In patients with hypothyroidism and gastrointestinal pathology, vitamin C improves the abnormalities in serum-free T4, T3, and TSH concentrations. This approach is helpful in the management of these patients3.”

Vitamin C: How Should You Supplement It?

The truth is that vitamin C is safe across a wide range of dosages.

However, higher doses of any individual antioxidant can run the risk of lowering the activity of the antioxidant our bodies make internally (including glutathione and NRF2).

Key Insight: The best-studied form of vitamin C, with thyroid disease, is ascorbic acid. The ideal daily amount is 400 – 500 mg for adults with thyroid disease.

3. Vitamin D

Deficiencies in vitamin D are, unfortunately, all too common. Those who have them are also at a higher risk for developing:

Hashimoto’s Thyroiditis
Graves’ Disease
Thyroid Cancer4

Vitamin D: The Evidence

The evidence behind vitamin D is that supplementation of it may lower blood levels of thyroid antibodies, particularly of anti-thyroid peroxidase (TPO)5,6.

It has also been shown to improve TSH levels by an average of 0.4 points7.

Vitamin D: How Should You Supplement It?

The ideal blood levels of vitamin D, for those with thyroid disease or general autoimmunity, are 30 – 50 ng/mL (Read More: All About Vitamin D)8.

Key Insight: That means that the best starting dose of vitamin D for adults with thyroid disease is 2000 IU daily, although some may need more to reach the desired blood levels.

4. Vitamin E

Nutrient deficiency test

When thyroid follicles convert iodide to iodine, iodine has the potential to cause free radical damage to thyroid cells (even though it is necessary to create thyroid hormone).

The benefit of vitamin E is that it works in conjunction with selenium, in order to protect the thyroid cells against damage9.

Vitamin E: The Evidence

One of the most interesting studied benefits of vitamin E is associated with memory. Memory loss, from thyroid disease, appears to relate to free radical stress within the brain.

Vitamin E is a fat-soluble antioxidant that can lower free radical stress. In animal studies, supplementation of it has been shown to improve cognitive function in hypothyroidism10.

Vitamin E: How Should You Supplement It?

In food, vitamin E is found in a wide variety of tocopherols and tocotrienols. Synthetic vitamin E, on the other hand, is alpha tocopherol only.

The best version of vitamin E, in its supplemental form, is isomers that include delta and gamma tocotrienols.

Key Insight: An ideal dose for adults with thyroid disease is 25 mg or 167% of the recommended daily value.

5. Vitamin K

We know that vitamin K is essential for healthy blood coagulation and bone metabolism.

In fact, abnormal thyroid hormone levels can increase the amounts of vitamin K needed for normal blood clotting11.

Vitamin K: The Evidence

Those with thyroid disease often have a greater risk of peripheral vascular disease, examples of which include:

  • Stroke
  • Aneurysms
  • Blood Clots

Vitamin K supplementation works in that it has been shown to lower vascular stiffness greater than a placebo12.

At the same time, people with abnormal thyroid hormone levels have a higher risk of bone thinning and hip fractures.

For this reason, larger studies would be helpful, but the initial research suggests that both dietary and supplemental vitamin K appear to help lower the risk of bone loss and improve bone repair in the body13.

Vitamin K: How Should You Supplement It?

Dietary vitamin K is otherwise called menaquinone, and it comes in a wide variety of subtypes.

Synthesized vitamin K1 is called phytonadione. Since studies show the benefits of both dietary and supplemental vitamin D, ideal supplementation would include a variety of dietary menaquinone compounds (in addition to vitamin K1).

Key Insight: An ideal dose for adults with thyroid disease is 25 mg or 167% of the recommended daily value.

6. Thiamine

Does Vitamin C Help Thyroid

Thiamine is a B vitamin that enables your body to produce energy from dietary carbohydrates.

In addition, it has been speculated that thiamine may play a role in fatigue secondary to thyroid disease. We only store thiamine in small quantities, so we need to ingest it regularly14.

Thiamine: The Evidence

In one recent study, thiamine was shown to resolve the fatigue secondary to Hashimoto’s thyroiditis. The results also showed up quickly — in a matter of hours or days!

The initial findings are encouraging and a larger follow-up study with a placebo group would certainly be more helpful15.

Thiamine: How Much Should You Supplement It?

Megadoses of thiamine is not recommended, as it may interfere with the cofactors needed for optimal mitochondrial function. For that reason, it should be avoided.

That said, the version of thiamine supplementation that is best documented for reversing thiamine deficiencies is thiamine hydrochloride (HCL).

Key Insight: The ideal daily dose for people with thyroid disease is 2.4 mg or 200% of the daily value.

7. Riboflavin

There have been studies showing that the symptoms of riboflavin deficiency closely mimic those of hypothyroidism16.

In addition to that, it has also been shown that abnormal thyroid levels can negatively impact riboflavin absorption17.

Riboflavin: How Much Should You Supplement It?

The preferred type of riboflavin in supplementation is known as riboflavin-5-phosphate. This is otherwise known as the active form of riboflavin.

Thyroid hormones are essential for the activation of riboflavin, and those with thyroid disease may not be able to convert it at all18.

Key Insight: The best amount of riboflavin for adults with thyroid disease is roughly 4 mg or 300% of the daily value.

8. Niacin

Like other B vitamins, niacin is essential thanks to its ability to produce energy from the breakdown of carbohydrates and fats.

Specifically, concerning those with thyroid disease, they may have a more difficult time generating energy from food because too much of it is stored as fat within the liver.

Niacin: The Evidence

The supplementation of niacin has been shown to help people with thyroid disease, by lowering the inactivating protein thyroid-binding globulin.

When this protein is lowered, thyroid hormones become more available for use by the cells19.

Niacin: How Much Should You Supplement It?

Delayed-release, slow-release, or time-released niacin supplements should be avoided, since they may slow thyroid function20.

Key Insight: The best dose of niacin for adults, with thyroid disease, is roughly 60 mg or 375% of the recommended daily value.

https://shop.drchristianson.com/products/chocolate-daily-reset-shake

Higher doses, those over 200 mg daily, can cause symptoms of niacin flushing and risks for visual damage due to niacin maculopathy21.

9. Vitamin B6

Does Vitamin C Help Thyroid 2

Studies have revealed that those with thyroid disease are prone to be low in many essential nutrients, including vitamin B622.

Thyroid hormones undergo numerous steps of conversion after they are produced. Some of this conversion is performed by the enzyme thyroid-hormone transaminase.

This enzyme is dependent on activated B6 (otherwise known as pyridoxal-5-phosphate)23.

Vitamin B6: The Evidence

Iron deficiency anemias are often common with thyroid disease. Yet, many people do not improve from iron supplementation.

That in mind, additional supplementation with B6 may help improve anemias that do not respond well to oral iron therapy24.

Vitamin B6: How Much Should You Supplement It?

Dietary sources and common supplements supply B6 in the form of pyridoxine.

The liver then converts pyridoxine to pyridoxal-5-phosphate (PSP). When people have higher levels of inflammation, they are often low in PSP (despite having an abundance of B6)25.

Key Insight: For this reason, PSP is the preferred form of B6 for those with chronic thyroid disease.

In addition, PSP is also safer than B6 across a wide range of doses. The ideal amount of PSP for adults with thyroid disease is roughly 6 mcg (or 400% of the recommended daily value).

10. Folate

Those with genetic variations of the MTHFR gene may be unable to safely utilize folic acid, the synthetic form of folate.

MTHFR gene variations are nearly universal in those with significant thyroid disease26.

Synthetic folic acid has been shown in animal models to directly suppress the production of T4 and T327. It may also be a risk factor for the development of colorectal cancer28.

Folate: The Evidence

Thyroid hormones regulate a group of chemical reactions called methylation. These reactions are important for things like:

  • Energy levels
  • Mood
  • Weight Loss
  • Detoxification

Folate supplementation has been shown to improve methylation in those taking thyroid medication29.

Folate: How Much Should You Supplement It?

In short, natural folate is definitely preferred over synthetic folic acid.

Quatrefolic is the version of folate that requires no conversion to be used as 5-methyl folate. Even those with multiple gene variations can utilize it.

Key Insight: The best dosage for adults with thyroid disease is 600 – 700 mcg or 170% of the recommended daily value.

11. Vitamin B12

As many as 40% of people with thyroid disease are deficient in B12.

Symptoms of low B12 in those with thyroid disease include:

  • Weakness
  • Impaired memory
  • Depression30

B12: The Evidence

In one study, when B12 was given to those with low B12 and deficiency symptoms, the majority saw their symptoms improve in as short as several months.

Some saw similar symptoms improve even though their B12 levels were not low to begin with31.

B12: How Much Should You Supplement It?

The most current version of bioavailable B12 is called methylcobalamin. New research has even shown that now oral B12 can be just as effective as injectable B1232.

Key Insight: The best amount of methylcobalamin for adults with thyroid disease is 200 mcg daily, or 8333% of the recommended daily allowance.

12. Biotin

One of the most troubling symptoms of thyroid disease is hair loss. Many find that it does not improve with thyroid medication.

It’s been found that up to 38% of women with hair loss may be low in biotin33.

Biotin: The Evidence

High-dose biotin supplementation consistently reverses biotin deficiency and related symptoms. It is also absorbed well orally and is completely safe.

Biotin: How Much Should You Supplement It?

It is important to first stop taking any vitamins that contain biotin within three days prior to having your thyroid blood tests drawn34.

When it comes down to it, biotin is best absorbed in the form of d-biotin. The ideal daily dose for adults with thyroid disease is 100 mcg per day or 333% of the recommended daily value.

Higher doses do not give greater benefit but may skew additional tests besides thyroid tests. This is true even when biotin supplements are avoided prior to testing35.

13. Calcium

Here’s something I really want you to know: calcium is crucial for those with thyroid disease.

That’s because abnormal thyroid levels can lead to bone thinning and hip fractures36. In addition, many with thyroid disease avoid dairy products due to the excess iodine content (or digestive issues).

Calcium: The Evidence

With diets low in dairy products, the recommended intake of calcium may be impractical without supplementation. Calcium supplements can even reduce the risk of hip fracture when used on a long-term basis37.

Calcium: How Much Should You Supplement It?

It is important to know that calcium supplementation can cause poor absorption of thyroid medication. Insoluble versions, like calcium carbonate, oyster shell calcium, and bone-derived calcium can impair the absorption of thyroid medications (even when separated by 10 hours).

Key Insight: Plant-derived calcium, such as dicalcium malate can safely be taken one hour after thyroid medication.

Since dicalcium malate is better absorbed, less is needed, 300 mg per day is an effective dose for adults with thyroid disease.

14. Magnesium

For healthy immune function and thyroid hormone metabolism, magnesium is essential (Read More: Magnesium to Boost Your Energy Levels).

Studies have shown that low levels of magnesium increase the risk of elevated antibodies against thyroglobulin and thyroid peroxidase and cause low thyroid function38.

Magnesium: The Evidence

In a small clinical trial, magnesium supplementation, along with selenium, was shown to improve thyroid function and ultrasonographic dings in a group of women with long-standing thyroid disease39.

Magnesium: How Much Should You Supplement It?

Magnesium can act as a powerful osmotic laxative.

This effect is a function of the type and the dosage of magnesium used, and it is responsible for many gastrointestinal side effects.

Dimagnesium malate is a well-absorbed type of magnesium that can be used in lower doses. A total intake of 300 mg per day, or 70% of the recommended daily value, is best for adults with thyroid disease.

15. Zinc

Zinc is essential for the production of thyroid hormones, as well as:

  • Their absorption and use by the cells
  • The conversion of T4 into T340

The relationship between zinc and thyroid disease even runs both ways. Low amounts of zinc can impair thyroid function, and impaired thyroid function can lead to zinc deficiencies41.

Zinc: The Evidence

Supplementing with zinc alone, or zinc with selenium, had pronounced effects on thyroid function in overweight women with hypothyroidism.

This study was a double-blind, placebo-controlled one. It also showed that zinc significantly improved both free T3 and free T4 levels (even though blood levels didn’t change)42.

Zinc: How Much Should You Supplement It?

Key Insight: The best supplementation of zinc is in the form of zinc bis-glycinate chelate, which should come in the form of 15 mg or 136% of the recommended daily value.

16. Selenium

Next to iodine, selenium has more effect on thyroid function than any single nutrient.

In fact, it is necessary for every stage of thyroid function, which includes:

  • Iodine absorption
  • Iodine activation
  • Hormone formation
  • Hormone release
  • Iodine uptake by the thyroid
  • TSH production
  • Cell membrane receptor response
  • Thyroid hormone conversion

Selenium: The Evidence

The supplementation of selenium has been shown to improve thyroid hormone levels and lower thyroid antibodies (regardless of a participant’s selenium levels)44.

For thyroglobulin antibodies, it may take 12 months to see a clear decrease, whereas three months may be adequate to see a decrease in thyroid peroxidase antibodies45.

Selenium: How Much Should You Supplement It?

The preferred form of selenium is a combination called SelenoExcell. It is the one form that has a spectrum of selenium chelations found in foods (including selenocysteine).

Key Insight: These forms are more easily regulated by the body, which is why the suggested amount is 100 mcg or 182% of the recommended daily value46.

17. Copper

optimal thyroid function

Copper is a known cofactor in the enzyme superoxide dismutase, which is essential for thyroid function.

In a study of over 1300 Americans, serum copper levels have been shown to be related to both fT3 and fT447.

Copper: The Evidence

There are no studies available on copper supplementation for thyroid disease.

That said, copper supplementation is well absorbed, and it is also effective at reversing the effects of copper deficiency48.

Copper: How Much Should You Supplement It?

The best absorbed forms of copper are the mineral chelates, such as copper bisglycinate chelate.

Key Insight: The ideal dose of copper for adults with thyroid disease is 1mg or 111% of the recommended daily value.

18. Manganese

Manganese is an essential cofactor in the enzyme 5’ deiodinase type 1 which is involved in activating thyroid hormones.

Daily ingestion of manganese over 10 mg from industrial may have negative effects on thyroid function49.

Manganese: The Evidence

There are no studies showing the effects of manganese supplementation on those with thyroid disease.

Manganese: How Much Should You Supplement It?

The best absorbed forms of manganese are the mineral chelates, such as manganese bisglycinate chelate.

Key Insight: Since manganese deficiency is rare, the best daily dose for adults with thyroid disease is 1 mg or 43% of the recommended daily value.

19. Chromium

Those with autoimmune thyroid disease are often low in a large number of nutrients, including chromium50.

Chromium has been shown to be essential for blood sugar regulation. In addition to that, many with thyroid disease have blood sugar abnormalities including diabetes, prediabetes, or hypoglycemia51.

Chromium: The Evidence

Chromium supplementation has been shown to improve type 2 diabetes and the complications of metabolic syndrome52.

Chromium: How Much Should You Supplement It?

There are several types of chromium that have been shown to be safe and effective in supplementation. One of the best documented forms is chromium nicotinate glycinate chelate.

Key Insight: The best amount for adults with thyroid disease is 200 mcg or 571% of the recommended daily value.

20. Molybdenum

In the large National Health and Nutrition Examination Survey of American adults, the risk for thyroid disease was correlated with lower levels of molybdenum53.

Other work in this subject has shown that molybdenum status has significant associations with fT4, fT3, and total T3 levels54.

Molybdenum: The Evidence

Molybdenum is well absorbed from supplementation. In fact, roughly 88 – 93% of oral doses enter the bloodstream55.

Molybdenum: How Much Should You Supplement It?

The best-standardized form of molybdenum is Molybdenum Glycinate Chelate.

Key Insight: Adults with thyroid disease are advised to take 100 mcg daily or 222% of the recommended daily value.

21. Omega-3 Fats (EPA and DHA)

A study compared dietary habits between 462 adults with thyroid disease against 1388 similar adults free of thyroid disease.

In it, it was found that one of the strongest predictors of autoimmune thyroid disease was a lower intake of omega 3 fatty acids56.

Omega-3 Fats: The Evidence

Fish oil supplements have been shown to lower pain and inflammation in those with autoimmune disease.

When used at recommended dosages, fish oil supplements are well-tolerated and have no typical side effects57.

Omega-3 Fats: How Much Should You Supplement It?

It is important to be sure that fish oil supplements have under 10 mcg of iodine per serving. That’s because many can be concentrated in high-iodine fish sources.

Key Insight: For adults with thyroid disease, the ideal dose of omega-3 fats is 1000 mg of EPA and 500 mg of DHA.

Bonus: Deiodinase Support

Thyroid hormones are carefully regulated by a group of enzymes called deiodinases.

These enzymes help convert T4 into T3, and T3 into T2. If they do not work well, too much reverse T3 can form. They are also important for the final steps of eliminating thyroid hormones.

Many of the essential vitamins and minerals help thyroid function by helping the body form deiodinase enzymes. There are three main deiodinase enzymes called:

  • D1
  • D2
  • D3

First, your body must get enough T4 and T3 to work with. This can come from your thyroid or from thyroid medication.

Once the hormones are available, it is up to the deiodinase enzymes to assure you have the right amount of each hormone inside the cells and inside the bloodstream.

The following table illustrates the differences between them58:

Enzyme  D1 D2 D3
Location Liver, kidney, thyroid Brain, pituitary gland, skeletal muscle Brain, placenta, fetal tissues
Action  Converts T4 into T3 and rT3. Converts T3 and rT3 into T2 Converts T4 into T3. converts rT3 into T2 Converts T4 into rT3. Converts T3 into T2
Blocked by  Fasting, chronic illness T3, cold exposure, overfeeding Cortisol, growth hormone
Active in Hyperthryoid patients unknown Pregnancy 

In blood tests, TSH scores show whether or not the body has enough thyroid hormone to work with. High TSH means too little thyroid hormone, and a low score means too much.

Roughly 0.5 – 1.9 IU/mL is a healthy range. There are some situations such as age, previous thyroid cancer, heart disease, or pregnancy that can change this goal.

When the TSH is at a good range and the hormone levels (T4, T3, or reverse T3) are not at a good range, the issue is usually the functioning of the deiodinase enzymes.

These enzymes depend on a variety of above-mentioned essential micronutrients for proper function. These include:

  • Selenium
  • Zinc
  • Copper
  • Pyridoxal 5 phosphate
  • Folate

Non-essential nutrients have also been shown to play a role in deiodinase enzymes. They include:

  • Trans-Resveratrol – Not only has it been shown to improve deiodinase function, but also helping thyroid cells respond better to TSH and helping it absorb enough iodine (but not too much)59. A useful dose for adults with thyroid disease is 10 mg daily.
  • Broccoli Sprout Extract – This helps deiodinase enzymes, and also improves the thyroid cells’ response to TSH (and may lower thyroid antibodies)60. A useful dose for adults with thyroid disease is 75 mg daily (with food).
  • Quercetin – This one regulates the D1 enzyme, and it also helps the thyroid better resist the harmful effects of excess iodine. A useful dose of quercetin for adults with thyroid disease is 50 mg daily with food.

Non-Nutritive Supplements

It also helps to consider other supplements that are not essential vitamins or minerals. That’s because these have been purported to be useful for thyroid function, and can include:

Supplement category Example
Animal extracts Bone broth
Herbal medicines Coleus forskohlii, Ashwagandha (withania somnifera) 
Sea vegetables Kelp (Laminaria spp.)
Essential oils Frankincense, lavender 
Probiotics  Bacillus subtilis, soil based organisms
Non essential amino acids Tyrosine, Taurine 
Fungi  Reishi, shiitake 
Inorganic mineral blends Shilajit, colloidal minerals

Does Your Multivitamin Need To Be Fermented?

The simple answer is no, it does not.

The fact is that fermentation changes complex molecules in ways that might make them more useful, but if it did have any effect on simple molecules (like vitamins) they would be less active.

Daily Reset Packs - Complete Nutrition - Dr. Alan Christianson

Action Steps: Multivitamins

So, should you take multivitamins? It’s a good idea for the following reasons:

The general beneficial health effects
The cost-effectiveness of only needing to invest in one type
A lower pill count to make the process simpler

Building on that, a thyroid-specific multivitamin may be crucial for your health. That’s because it does two things, it includes the essential ingredients that you should have, and voids the harmful ingredients which you must avoid.

In fact, one study worth mentioning suggests that multivitamins can be safe for long-term use of over ten years. That’s important because it means over time you are safe to use them!61

Too Much Of A Good Thing?

It is common to think that if a nutrient helps with something, then higher amounts of the nutrient must be more helpful.

Key Insight: In the case of thyroid function, this is often not the case. All nutrients have levels above which they become counterproductive.

It is often the case that the very thing a nutrient helps with at the right dose, it can block at an excessive dose. The balance is delicate, and you need to be mindful of it.

Most people with thyroid disease are missing some vital nutrients while taking others in doses that are counterproductive.

The following is a summary table that shows which nutrients are helpful, which forms and doses are best, and how much is excessive.

Nutrient Preferred form Amount Excessive Amount
Fat Soluble Vitamins
Vitamin A Mixed carotenoids and palmitate 320 mcg RAE Over 1000 IU Daily
Vitamin C Ascorbic acid 400 mg Over 1000 mg daily
Vitamin D D3 Cholecalciferol 2000 IU Per blood levels
Vitamin E Vitamin E isomers, DeltaGold delta and gamma tocotrienols 25 mg Over 300 IU daily
Vitamin K K1, K2 and Full Spectrum MK6, 7, 9 450 mcg Over 600 mcg daily
Water Soluble Vitamins
Vitamin B1 – Thiamin Thiamine HCL and Bentofamine 2.4 mg Over 25 mg daily
Vitamin B2 – Riboflavin Riboflavin-5-Phosphate 4.2 mg Over 25 mg daily
Vitamin B3 – Niacin Niacinamide and Niacin 60 mg Over 100 mg daily
Vitamin B5 – Pantothenic acid Calcium Pantothenate 5 mg Over 25 mg daily
Vitamin B6 Pyridoxal-5-Phosphate 6.7 mg Over 25 mg daily
Vitamin B7 – Biotin d-Biotin 100 mcg Over 300 mcg daily
Vitamin B9 – Folate Quatrefolic folate 5-methyltetrahydrofolate 680 mcg Over 1000 mg daily
Vitamin B12 Methylcobalamin 200 mcg Over 500 mcg daily
Minerals
Calcium di-Calcium malate 350 mg Over 500 mg daily
Magnesium di-Magnesium malate 300 mg Over 500 mg daily
Zinc Zinc  bisglycinate 15 mg Over 30 mg daily
Selenium SelenoExcell natural selenium 100 mcg Over 300 mcg daily
Copper Copper  bisglycinate 1 mg Over 2 mg daily
Manganese Manganese bisglycinate 1 mg Over 5 mg daily
Chromium  Chromium Nicotinate Glycinate 200 mcg Over 400 mcg daily
Molybdenum  Molybdenum glycinate 100 mcg Over 500 mcg daily
Boron  Boron glycinate 1 mg Over 3 mg daily
Essential Fatty Acids
EPA Eicosapentaenoic Acid 1000 Over 2000 mg daily
DHA Docosahexaenoic Acid 500 Over 1000 mg daily
Deiodinase Support
Resveratrol Trans Resveratrol 10 mg
Broccoli seed extract 75 mg
Quercetin 50 mg

Bottom Line: The goal in supplementing to improve thyroid function is to get enough of each of the recommended nutrients without going over the excessive amounts.

The Logistics of Multivitamins

There are, of course, several practical considerations that come up, which include:

  • Ongoing costs
  • Pill count
  • Convenience

The good news is that the Daily Reset Pack is formulated with all of this in mind. It is 1 packet, taken twice daily with food. What follows is a cost breakdown to showcase just how much it can help save you, too:

Why Traditional Multivitamins Can Be A Problem

There are some important things to keep in mind when it comes to multivitamins.

I developed the Daily Reset Pack to be mindful of all these things, but typical multivitamins for those with thyroid disease may encounter the following issues:

  • Iodine (Read More: All About Iodine)
  • Folic Acid
  • Too much vitamin A (leading to birth defects or cancer risk)
  • Minerals that won’t absorb
