Who This Course Is For
This course is for people who want to improve their thyroid function and metabolic rate using the most appropriate thyroid medication or over‑the‑counter thyroid‑support supplement — without confusion, overwhelm, or guesswork. If you’ve been searching for clarity in a sea of conflicting advice, this course gives you a clear, science‑based path forward.
Why Thyroid Treatment Feels So Confusing
Many people feel lost in the contradictory opinions surrounding thyroid treatment. Should you use T4‑only therapy or a T4 + T3 combination? Are synthetic hormones better, or is natural desiccated thyroid (NDT) the right choice? Why do some people feel worse on T4‑only medication, even when their labs look “normal”? With so many opposing viewpoints, it’s no wonder thyroid healing feels complicated and overwhelming.
A Clear, Practical Approach Based on Real‑World Experience
I created this course based on my own thyroid‑recovery journey and the unique T4 + T3 approach of thyroid expert Dr. Ray Peat — an approach that helped me and many others finally make sense of thyroid treatment. Inside, I guide you through the major approaches to thyroid therapy, explain the key differences between them, and help you understand why Dr. Ray Peat’s T4 + T3 protocol may offer important advantages for symptom relief and more effective metabolic support.
Understand How Thyroid Hormones Regulate Metabolism
You’ll learn how thyroid hormones regulate metabolism and energy production, and how common low‑thyroid conditions — including hypothyroidism and Hashimoto’s — can create a wide range of symptoms by pushing the body into a state of low cellular energy. This foundational understanding helps you see why symptoms persist even when standard lab tests appear “normal.”
Learn to Interpret Thyroid Tests With Confidence
The course includes a clear, practical breakdown of thyroid testing so you can interpret your lab results with greater confidence. You’ll also learn how to use pulse and temperature as simple, reliable tools for evaluating your metabolic health at home — a core part of the Ray‑Peat‑aligned approach.
Choose the Right Thyroid Therapy for Your Body
By the end of this course, you’ll have a deeper understanding of your thyroid and metabolic health — and you’ll know how to choose the most appropriate type of thyroid support, whether that’s a synthetic T4 + T3 combination, natural desiccated thyroid (NDT), or over‑the‑counter thyroid glandulars. You’ll also learn how to take your thyroid support correctly and titrate your dosage to reduce side effects and support steadier, more predictable progress.
Trusted Medication and Supplement Recommendations
The course includes recommendations for reliable brand‑name thyroid medications, high‑quality over‑the‑counter thyroid‑support supplements, and effective thyroid glandulars. These insights help you avoid low‑quality products and ineffective options so you can make informed, confident decisions.
Avoid the Costly Trial‑and‑Error Cycle
Without the right knowledge, it’s easy to waste time, money, and energy on trial and error while symptoms continue and confusion grows. This course gives you the clarity, structure, and confidence you need to move forward with a thyroid‑support plan that actually works — so you can restore energy, improve metabolism, and finally feel like yourself again.

Course Phases & Modules
3 phases · 15 modules
Gain Clarity on Your Thyroid Function and Metabolic Health
In this phase, you will gain clarity on your thyroid function and metabolic health so you can better understand what may be contributing to your symptoms. You will learn how thyroid hormones influence metabolism, how to better interpret common thyroid lab tests, including TSH, T4, T3, and thyroid antibodies, and how to track your metabolism at home using temperature, pulse, and symptoms. By the end of this phase, you will have a strong foundation for understanding thyroid disorders, including hypothyroidism and Hashimoto’s thyroiditis, as well as a clearer picture of your current thyroid and metabolic health.
Thyroid Function & Metabolism
How your thyroid sets the speed of your metabolism — and why every cell in your body depends on it working well.
Hypothyroidism & Hashimoto’s Thyroiditis
What happens when active T3 runs low, the three root causes I see most often, and why Hashimoto's is more common than most people realise.
Understanding TSH
What the TSH test actually measures, why it is a clumsy guide on its own, and how to read it without being misled.
Thyroid Blood Testing
Why TSH and T4 alone are not enough — and the full panel I rely on to see what your thyroid is really doing.
Tracking Metabolism with Pulse, Temp & Symptoms
Two simple home measurements — temperature and pulse — that tell you more about your thyroid than most blood tests ever will.
Understand Your Thyroid Treatment Options
In this phase, you will learn about the main thyroid treatment options and how they differ so you can make more informed decisions about your care. You will better understand when thyroid medication may be appropriate, why T4-only treatment does not work well for everyone, how T3 works in the body, and how combined T4 and T3 therapy compares with natural desiccated thyroid. By the end of this phase, you will have a clearer understanding of the most common treatment approaches and which options may be worth discussing with your doctor.
Do I Really Need Thyroid Medication?
How diet and stress drive most cases of hypothyroidism — and the questions to answer before reaching for a prescription.
The Problem with T4 Only Treatment
Why levothyroxine (Synthroid) works for some and leaves so many still tired — and the conversion problem most doctors never check for.
Understanding T3 in the Treatment of Hypothyroidism
When pure T3 (Cytomel, Cynomel, Thybon) makes sense, when it does not, and how to dose it without the rollercoaster.
Dr. Ray Peat's T4 + T3 Protocol
The combination protocol Ray Peat refined over decades — designed to mimic a healthy thyroid gland, not just patch a number.
Natural Desiccated Thyroid (NDT)
What NDT really is, the brands worth knowing (Armour, Erfa, Thyroid-S), and why this old-fashioned medicine still outperforms newer ones for many.
Over the counter Thyroid Supplements
A guide to the OTC thyroid glandulars I trust — what to look for on the label, how they compare to prescription NDT, and where to find them.
Use Thyroid Support More Effectively and Safely
In this phase, you will learn how to use thyroid medication and over-the-counter thyroid support supplements, also known as thyroid glandulars, more effectively and safely in daily life. You will better understand dosing, timing, absorption, and how to track your response so you can make more informed decisions and avoid common mistakes. By the end of this phase, you will have a clearer, more practical routine for using thyroid support with greater confidence and safety.
Optimal Thyroid Dosage?
How to think about a daily dose — what 'two grains' really means and how to land on the T4-to-T3 ratio your body responds to.
How to Take Your Thyroid Medication?
The practical rules: when to take T4, why T3 always needs food, splitting doses, and the small habits that make a big difference.
Tracking Your Metabolic Response to Thyroid Therapy
How to start low, build up safely, and read the signs — pulse, temperature, mood, sleep — that tell you the dose is right.
The Thyroid-Adrenal Connection
Why some people feel worse on thyroid medication, what 'adrenal fatigue' actually means, and how to support both glands together.
