Description

Will T3 Conversion Booster single-handedly manage 100% of your thyroid symptoms and render your thyroid medication unnecessary?

Definitely not!

But it is a physician-formulated thyroid support supplement designed to help your body and thyroid create more of the most powerful thyroid hormone that exists: T3.

Increase Free T3 Levels Naturally with T3 Conversion Booster

T3 Conversion Booster contains 10 unique and specific ingredients designed to help the 3 most important pathways involved in thyroid function:

#1. T4 to T3 Conversion (this may be the most important)

#2. Thyroid Cellular Sensitivity

#3. Thyroid Hormone Biosynthesis (the creation of thyroid hormone)

These 3 steps help your body not only create thyroid hormone but also allow that thyroid hormone to be active at the cellular level.

Due to nutrient deficiencies, poor diet, and soil depletion, many patients may end up with sub-optimal levels of these nutrients.

The replacement of these nutrients has been shown in clinical studies to help improve thyroid hormone levels if deficient.

T3 Conversion Booster was designed to help patients stuck in the conventional treatment paradigm of T4-only thyroid treatment. These patients are often on T4-only medications such as Levothyroxine, Tirosint, and Synthroid.

In this setting taking supplements designed to increase free T3 levels may actually improve thyroid function overall.

This can be accomplished by replacing nutrient deficiencies, reducing inflammation, and by promoting thyroid hormone biosynthesis.

The 3 Thyroid Boosting Blends in T3 Conversion Booster

T3 Conversion Booster is specifically designed to contain ingredients that help boost thyroid conversion. This unique blend of ingredients helps the body increase the natural T4 to T3 conversion process by providing the necessary nutrients for this process and by helping to reduce inflammation which can act to reduce this process.

  • Guggul extract –> Studies have shown that guggulsterone may exhibit a strong thyroid stimulatory action when taken daily, in addition, studies have shown that guggul extract increases iodine uptake and enhances thyroid peroxidase function.*
  • Rosemary Extract –> This powerful anti-oxidant helps reduce inflammatory levels in the body and may help improve T4 to T3 conversion through this mechanism. Rosemary has also been shown to help improve cognition and may act as both an anxiolytic and anti-depressant.* (See literary references below)*
  • Ashwagandha –> Ashwagandha is an adaptogenic supplement that has been shown to help increase T4 and T3 levels, normalize TSH levels in patients with subclinical hypothyroidism and help improve cortisol regulation. This isn’t even taking into account the beneficial effects that Ashwagandha has on weight loss and the building of muscle mass. These benefits make Ashwagandha one of the premiere thyroid nutrients.*
  • Zinc –> Zinc acts as an antioxidant and anti-inflammatory agent in the body. Zinc also helps promote T4 to T3 conversion and many patients are zinc deficient.*
  • Selenium –> Selenium helps improve immune function and also helps promote T4 to T3 conversion and works very well when combined with zinc.*

In addition to boosting T4 to T3 conversion, your body must also be able to adequately utilize thyroid hormone at the cellular level. Several nutrients have been identified to be involved in this process and these ingredients are included in T3 conversion booster.

  • Vitamin A –> Vitamin A deficiency results in a reduction in total T3, total T4, Free T3, and free T4 which improves upon replacement. Furthermore, Vitamin A therapy appears to be involved in the enzymatic conversion of T4 to T3 in addition to thyroid cellular action.*
  • Zinc –> In addition to improving T4 to T3 conversion, zinc also may help promote thyroid cellular function.*
  • Iodine –> Iodine creates the backbone of thyroid hormone and is required in optimal amounts for proper thyroid hormone production. Low iodine may result in reduced thyroid function and hypothyroidism. Regulatory bodies recommend 150mcg of iodine daily for non-pregnant and non-lactating women and up to 220 to 290mcg per day for pregnant and lactating women while the average American daily consumption of iodine is estimated to be around 130mg per day. This creates up to a 20mcg to 90mcg deficiency in iodine per day in individuals unless they are actively consuming iodine-rich foods.
  • Vitamin D3 –> Patients with low thyroid function and more likely to have low levels of Vitamin D. In addition, the severity of hypothyroidism tracks closely with the degree of Vitamin D deficiency. Vitamin D also plays an important role in immune function and low levels increase the risk of developing an autoimmune disease such as Hashimoto’s thyroiditis.
  • Vitamin E –> Vitamin E helps protect the integrity of your cell membranes and acts as a powerful anti-oxidant which may indirectly help improve thyroid function.

Why Dr. Childs Recommends It

T3 is the most important thyroid hormone in your body. As a thyroid patient, you should put most of your effort and energy into improving T3 levels if you want to feel better!

T3 Conversion Booster was specifically formulated to naturally help your body create more of that powerful thyroid hormone. And because so many thyroid patients aren’t converting well, enhancing this process is a no-brainer for just about every thyroid patient.

Symptoms of Low T3 & Signs You Need More

Did you know that you can still have hypothyroid or low thyroid symptoms even though you are taking thyroid hormone replacement medication?

These symptoms may stem from an underlying problem known as low T3 syndrome.

Low T3 syndrome may result in hypothyroid symptoms even though your TSH and free T4 levels may be relatively normal.

T3 is the single most important thyroid hormone because it is THE active thyroid hormone in your body.

How do you know if you have low T3?

You can assess your T3 levels with serum laboratory tests such as free T3, but you can also find low T3 levels through clinical assessment of your symptoms.

Symptoms of Low T3 include:

  • Weight gain despite healthy eating and exercise
  • Cold hands and extremities despite taking thyroid medication
  • Swelling, especially around the eyes
  • Fatigue or low-energy
  • Menstrual irregularities
  • Low body temperature and/or low resting heart rate
  • Hair loss, brittle hair, and/or brittle nails
  • Depression, anxiety, or mood changes
  • Chronic constipation

The presence of these symptoms may indicate persistent thyroid dysfunction and should prompt further testing and evaluation for nutrient deficiencies involved in thyroid hormone conversion and production.

Frequently Asked Questions

Yes! T3 Conversion Booster was designed to be used with all thyroid medications including those that contain T3 like Cytomel, liothyronine, and formulations of NDT like Armour Thyroid.

You can take it with any type of thyroid medication but be sure you don’t take it at the exact same time as your medication.

For best results, take T3 Conversion Booster 30-60 minutes away from your thyroid medication (either before or after).

In short, maybe, but not always.

In general, thyroid support supplements typically do not have a big impact on thyroid lab tests compared to thyroid medications.

This is because they each contain different ingredients and each has a different mechanism of action.

Thyroid medications typically have a bigger impact on thyroid lab test levels like TSH, free T3, free T4, and reverse T3.

Thyroid support supplements like T3 conversion booster tend to work more at the cellular level which impacts symptoms but doesn’t always impact thyroid lab test results.

This isn’t always the case, though, as some people do see changes to their lab tests when using these types of supplements.

But because of the reasons listed above, the best way to determine if it’s working for you is by evaluating how you are feeling, not your thyroid lab tests.

Yes! T3 Conversion booster is still beneficial to those without a thyroid and for those without a functioning thyroid gland.

Those without a functioning thyroid gland still need to produce T3 (more so than those with an active thyroid gland) and this conversion process occurs outside of the thyroid gland.

For this reason, T3 Conversion Booster is even more important for those who are taking thyroid medication and for those without a thyroid gland.

Each of these supplements supports your thyroid in a different way and here’s an easy way to differentiate them:

T3 Conversion Booster primarily helps your thyroid convert T4 into T3 and produce more T3 thyroid hormone.

Thyroid Adrenal Reset Complex provides support to the thyroid-adrenal connection.

Thyroid Glandular+ provides direct support to the thyroid gland as well as the pituitary gland.

Each supplement was created to target a different aspect of thyroid function which is why they can all be used together.

T3 Conversion Booster is considered a low thyroid support supplement so you generally would not want to take it if you are in a state of thyroid overactivity or hyperthyroidism.

Having said that, there are a few situations where it may make sense to use low thyroid support if you have been labeled with hyperthyroidism:

#1. If your thyroid has been surgically removed. If your thyroid has been removed then you are considered to be hypothyroid even if the reason for the removal was due to hyperthyroidism.

#2. If your thyroid has been ablated with radioactive iodine. If your thyroid has been ablated then you are considered to be hypothyroid even if the reason for the ablation was due to hyperthyroidism.

#3. If you are undergoing block and replace therapy or add-back therapy for hyperthyroidism.

Block and replace therapy is an uncommon treatment used in some situations where a patient with hyperthyroidism will take both thyroid medication like levothyroxine as well as thyroid blocking medication like methimazole.

If you are undergoing this kind of treatment (which is uncommon) then you can consider thyroid support supplements as well.

In general, if you are using thyroid-blocking thyroid medication like methimazole then you probably shouldn’t use T3 Conversion Booster.

On the other hand, if you are taking any sort of thyroid medication replacement like levothyroxine (or any others) then you can consider using T3 Conversion Booster.

Absolutely!

If you are trying to lower reverse T3 levels then focusing on free T3 makes a lot of sense.

Here’s why:

Your body has the option to turn T4 into either T3 or reverse T3. When you push the pathway down the T4 to the T3 route, you will necessarily reduce how much T4 is available for reverse T3 production.

So anything that decreases T4 to reverse T3 conversion will increase free T3 and anything that increases T4 to T3 conversion will decrease reverse T3.

T3 Conversion Booster contains two ingredients that can sometimes be problematic for those who are pregnant: vitamin A and ashwagandha.

These aren’t necessarily harmful, but you will get differing opinions on their use during pregnancy depending on who you are talking to.

For this reason, we always recommend that you get approval from your ob/gyn or midwife (or whoever is caring for you during pregnancy) prior to using any supplement including this one.

Yep! You don’t need to be taking thyroid medication in order for this supplement to help.

It just so happens that many thyroid patients are already taking thyroid medication but there are plenty who aren’t and they have had success when using this supplement as well.

Great question!

We’d all like to believe that our doctors are 100% up to date on the latest research as it pertains to all aspects of our health and thyroid but that just isn’t the case.

If thet were then we wouldn’t have an epidemic of unhappy thyroid patients who still struggle with low thyroid symptoms despite taking their thyroid medication and doing everything else correctly.

For now, the existing thyroid treatment paradigm leaves a lot to be desired for those suffering from thyroid disease which needs they often need extra help outside of traditional medications and treatments.

These treatments in the form of supplements and lifestyle changes are only necessary for those people who are not feeling 100% right now.

If you are someone who is not experiencing symptoms like fatigue, weight gain, cold intolerance, pain, depression, and so on, then you’d have no need for using thyroid support supplements like T3 Conversion Booster.

But if you are like many other thyroid patients out there who are still suffering then it would be worth considering!

Nope!

T3 Conversion Booster contains natural ingredients which help your own body produce T3.

This means that there is never a risk of overproducing T3 and that it can be added to medications that contain T3.

The recommended dose is 2 capsules taken each day (with or without food) before noon and at least 30-60 minutes away from your thyroid medication (if you take any).

At 2 capsules each day this supplement will provide you with a 60-day supply.

Some thyroid patients may benefit from doubling this dose up to 4 capsules per day by taking 2 capsules in the morning and 2 capsules in the afternoon/evening. This is ideal for those with high reverse T3 levels or very low T3 levels.

The biggest difference is that T3 Conversion Booster does not contain active T3 thyroid hormone. It contains natural ingredients designed to help your body produce more thyroid hormones on its own.

T3 thyroid medication contains the active T3 thyroid hormone which is why it requires a prescription.

T3 Conversion Booster can be taken indefinitely and I recommend using it for as long as it is helping you feel better.

Thyroid function is slow to respond when compared to other hormone systems in the body.

It takes 6 weeks of daily use of any thyroid hormone or thyroid support supplement before your body will reach a steady state which means it will take this long before it completely enters your system.

It’s usually around this time that you will start to see changes in how you are feeling but I recommend using any thyroid support supplement or medication for at least 90 days before determining whether or not it’s working for you.

The best way is to pay attention to how you are feeling! Most people know it’s working because they feel an increase in energy, an improvement in well-being, and an improvement in their thyroid symptoms.

What type of improvement you may experience depends largely on how your thyroid is impacting your overall health. Each person has a slightly different set of symptoms so how they respond to T3 Conversion Booster will vary as a result of this.

No, getting your T3 tested is not required before using this supplement. Having said that, you are certainly welcome to do that if you’d like!

T3 conversion booster is a supplement (not a medication) which means that it is generally very well tolerated and has minimal side effects.

Yes! In addition, it does NOT contain wheat, gluten, yeast, soy protein, dairy products, fish, shellfish, peanuts, tree nuts, eggs, artificial colors, artificial sweeteners, or artificial preservatives.

Yes! T3 Conversion Booster has been used by thousands of patients with Hashimoto’s without any issues. I formulated T3 Conversion Booster with a small dose of iodine accompanied by selenium to protect against any iodine-related issues.

Remember: Iodine is required by all humans because we can’t produce it on our own and we need it for thyroid hormone production. The key to using iodine safely is to use the right dose and combine it with selenium. This supplement was specifically formulated to meet these requirements which is why it is quite safe.

Each serving of T3 Conversion Booster contains 75mcg of Iodine which is well below the recommended high range of iodine intake of 300mcg per day.

Yes!

T3 Conversion Booster is still helpful even for those without a thyroid.

This is for several reasons including:

#1. Thyroid conversion occurs outside of the thyroid gland. In other words, this process is still important and continues to occur even if your thyroid gland has been removed or has been damaged.

And #2. Most thyroid patients without a thyroid are using T4-only thyroid medications like levothyroxine and Synthroid.

We know from research studies that patients without a thyroid are usually unable to obtain optimal T3 levels with T4 thyroid medications alone.

For this reason, it’s usually more important for someone without a thyroid to take T3 thyroid support supplements.

Hypothyroidism bundle

I started your bundle for hypothyroid about 3 1/2 Months ago . I’ve been taking them everyday faithfully. I get my lab work done in May . I’m excited to see if your bundle works for me . I do feel better with all my symptoms, except for hair loss . I will be ordering again until lab work . I’m not quitting until I see my labs . If it’s helping I’ll keep up with them . I started the collagen powder too. Time will tell.

T3 booster - hoping it’s helping!

I recently started taking levithyroxine for hypothyroidism, and soon after, started taking the T3 conversion booster. I honestly can’t say if they are a tremendous help or not, since I started both around the same time. But overall I’m feeling better, so I’m going to order another bottle to go with my Rx.

High Quality Products - Definitely Worth the Investment

I have been very encouraged by the added benefit I seem to be experiencing from the addition of the T3 Conversion Booster. Since adding the Booster I've notice a consistent marked improvement in my energy level and ability to initiate & stayed focused on tasks. I have made it part of my daily supplement regimen.

I have also noticed the T3 Conversion Booster seems to compliment & support your Daily Essentials Multivitamin very well; after having previously ordered the later some time ago & just adding the Booster with my most recent order.
While I do not take the recommended 4 Daily Essentials capsules each day -- as I have long been in the habit of taking other daily supplements & continue to do so (D, C, A, B-complex, Magnesium, Tyrosine, Theanine) -- [though not always consistently] -- I do make it a point to take 2 Daily Essential capsules with the T3 Booster each morning.

As noted I do believe the addition of each of these products has enhanced my thyroid health; as evidenced by overall improvement in functioning and adjustment over the past several months. I recently retired & have become involved in several 'extra-curricular' activities which I simply hadn't had time, interest, or energy for before retiring. It has been VERY encouraging to find I am having much more motivation, initiative, willingness, & interest in starting & following through on activities. As a Behavioral Health Services professional for 34 years', first diagnosed with hypothyroidism way back in 2004, I've been on Synthroid for a very long time... And I KNOW both of these products (Daily Essentials & T3 Booster) have been a great boon to my overall thyroid health.

I will continue to use and endorse your products. Thank you!
