What’s inside (3 Products)
Over The Counter Desiccated Thyroid Gland Powder (Thyroid Glandular+)
Why it’s in the stack:
- Provides grass-fed bovine desiccated thyroid gland powder: This OTC ingredient is the closest ingredient you can get to NDT medications like Armour Thyroid and NP Thyroid.[11][13]
- Supplies natural cofactors and enzymes missing from standard thyroid medication: Due to its source, you get access to all of the naturally occurring compounds found inside the thyroid gland.[9][10]
- Supports thyroid function: With the inclusion of ingredients like L-tyrosine, selenium, and other glandular components.[1][2][3]
How to use: Take 2 capsules in the afternoon, on an empty stomach (30-60 minutes away from food).
T4 to T3 Conversion Supplement (T3 Conversion Booster)
Why it’s in the stack:
- Supports the creation of active thyroid hormone (T3): Botanical ingredients and minerals help your body naturally create more T3 through the conversion process.[31][32][33]
- Provides thyroid nutrient support: Cofactors like selenium, zinc, and ashwagandha optimize thyroid hormone function in your cells.[27][29][30]
- Helps reduce thyroid-blocking hormones: By improving T4 to T3 conversion, it helps reduce reverse T3 creation.[14][24][25]
How to use: Take 2 capsules each morning with breakfast.
Bioidentical T2 Thyroid Hormone (Essential T2)
Why it’s in the stack:
- Boosts Metabolism: T2 has a direct impact on mitochondrial activity, which enhances caloric burn at rest and energy production in the cells. The combined effect is more energy to stay active with more fat-burning potential.[36][38][40]
- Supports steady T3 and T4 levels: T2 is created from the breakdown of T3. When you take T2, you send signals to your body that you don’t need to break down your T3, which stabilizes the conversion process upstream.[39][43][44]
- Complements other thyroid medications and supplements: T2 works alongside thyroid medication and thyroid support supplements and enhances their effects, making it the perfect complementary therapy.[37][42]
How to use: Take 1-2 capsules (max dose of 300 mcg per day) at bedtime, on an empty stomach (30-60 minutes away from food).
Why It Works
Complete Desiccated Thyroid Glandular Support
Standard thyroid medications only provide one type of thyroid hormone: T4. Other medications like NDT contain much more, but they are gated behind a prescription. Enter desiccated thyroid gland powder: your way of getting OTC ingredients you can’t get anywhere else.[8][11]
Bioidentical Source of T2 Thyroid Hormone
T2 is the only active thyroid hormone available over the counter. And with our unique batch-up manufacturing process, we ensure consistent dosing with every lot. Thousands of thyroid patients use T2 for its benefits on weight, metabolism, energy, and fat burning.[40][44]
The Foundation Bundle for Thyroid Patients
By combining conversion support, OTC grass-fed gland powder, and thyroid hormone support with T2, this core thyroid trio targets all three major pathways that thyroid patients need. If you want a natural solution to your thyroid problem, this is the place to start.[19][39]
Who It’s For
Designed for thyroid patients who:
- Have “normal” labs, but still feel off
- Struggle with stubborn symptoms like fatigue, weight gain, or brain fog even on medication
- Aren’t getting the results they want from levothyroxine, Synthroid, or other thyroid medications
- Prefer a natural, root-cause approach to managing and treating their thyroid
How to Use (Simple Routine)
Here’s your new schedule:
- Morning: 2 capsules of T3 Conversion Booster with breakfast.
- Midday: 2 capsules of Thyroid Glandular+, on an empty stomach (30-60 minutes away from food).
- Evening: 1-2 capsules of Essential T2 right before bedtime, on an empty stomach (at least 30-60 minutes away from food).
*Note: Essential T2 can be taken at the same time as other thyroid medications.
What To Expect
- Week 1-2: Energy will start to improve, fewer midday crashes, and better focus.
- Week 3-4: Mood will improve, sleep will improve, and metabolism will feel more active.
- Week 6-8+: Improvement in thyroid-related symptoms, fat loss is easier to maintain, and long-term thyroid support continues to build for several months.

Frequently Asked Questions
Can I take this with thyroid medication?
Absolutely. The core thyroid trio was designed to be taken alongside all forms of thyroid medication, but it is not required that you take thyroid medication for it to work.
With the exception of Essential T2, the other supplements should be taken 30-60 minutes away from thyroid medication (if you take any).
Will it help me get off my thyroid medication?
Maybe. Here’s what you need to know:
The ingredients in this bundle provide complete thyroid support, but they are not a replacement for thyroid medication.
That said, by supporting your thyroid with these ingredients, hormones, enzymes, and prohormones, you can increase your odds of getting off your medication.
Every person is unique and each situation is different, so this is not always possible. But if you want to try it, we recommend working with your physician.
Is this safe if I have Hashimoto’s?
Yes! This trio formula was designed to be gluten-free, dairy-free, and soy-free, and contains ingredients that not only support the thyroid but also the immune system.
Will this help if I’m already taking thyroid medication?
Yep! In fact, the ingredients in this bundle can help your thyroid medication work more effectively by improving thyroid hormone conversion, absorption, and cellular activity.
Will it work if I no longer have a thyroid?
Yes! Even (especially) without a thyroid, your body still needs help using and activating thyroid hormones.
These supplements also provide direct thyroid hormones (T2 and glandulars) plus key cofactors and enzymes that are no longer present in your body if your thyroid has been removed.
What are the ingredients in each product?
- Thyroid Glandular+: Grass-fed thyroid gland powder, iodine, selenium, dulse, adrenal gland powder, Irish moss, L-tyrosine, anterior pituitary gland powder, bladderwrack, spleen powder, thymus gland powder.
- Essential T2: T2 as 3,5 diiodo-l-thyronine.
- T3 Conversion Booster: Vitamin A, vitamin D3, vitamin E, iodine, zinc, selenium, guggul extract, ashwagandha, rosemary extract.
