About Us – Thyroid Authority
Who We Are
Dr. Jason Bradley and Dr. Rachel Bradley created Thyroid Authority to help people who feel "lost in the system" reclaim Radiant health.
Dr. J is a functional‐medicine doctor with more than two and a half decades of clinical experience. He and his wife Dr. Rachel both reversed their own thyroid and Hashimoto's conditions using the approach they now teach, and Dr. J's 2023 international best-selling book, The EPIC Five Plan made him a sought‑after speaker at medical conferences nationwide, but you probably know him as the host of the top-ranked Apple podcast, Get Better Faster.
They now operate a virtual practice that gives people around the world access to physician-led care—helping those who feel exhausted, frustrated, and unheard after being dismissed, overlooked, or told everything is “normal” finally uncover the root cause of their symptoms, restore their energy, and reclaim their health, confidence, and lives.
Our Mission
"We help women with thyroid conditions — diagnosed, misdiagnosed, or dismissed — finally understand what’s going on in their bodies and follow a proven plan to reclaim their energy, their confidence, their relationships, and their lives."
In conventional medicine, hypothyroidism and Hashimoto’s disease are treated as a one‑size‑fits‑all problem. The reality is, Hashimoto’s is an autoimmune condition that can cause hypothyroidism and related symptoms. People often suffer with frustrating fatigue, weight gain, low mood, sleep disorders, hormonal imbalances, constipation, and more. Women are about ten times more likely than men to develop Hashimoto’s, with diagnoses peaking between ages 30‑50, the very period when careers, families and social lives demand your best. Many people receive “normal” thyroid blood test results yet still experience debilitating symptoms and don’t know what to do next. Dr. J and Dr. Rachel knew there had to be a better way...so they created it.

Our Approach
We practice personalized functional precision medicine, which focuses on identifying and treating the root causes of disease rather than suppressing symptoms. At Thyroid Authority, we restore healthy function by investigating underlying processes and dysfunctions, integrating laboratory investigation, genetics, environment, and lifestyle to create personalized interventions. This whole‑person approach treats physical, mental, and emotional factors that lead to truly transformational outcomes.
At Thyroid Authority we:
Investigate deeply
Beyond a single thyroid‑stimulating hormone test. Comprehensive panels (including T4, T3, reverse T3, auto‑antibodies, micronutrients, and more) help pinpoint why your thyroid isn’t working optimally. We review your genetic predispositions, environmental exposures, as well as gut, adrenal and immune function.
Personalize care
No two people experience hypothyroidism the same way. Our EPIC Five Plan (rooted in hydration, nutrition, movement, nervous‑system regulation, and circadian rhythm) is tailored to your unique physiology, lifestyle and goals.
Use evidence‑based therapies
We combine conventional diagnostics with natural therapies, targeted supplementation, nutrition, and therapeutic lifestyle intervetnions. When medication is necessary, we help you find the right dose and form.
Coach and empower
Healing is a partnership. You receive direct access to seasoned doctors, experienced coaches, and a supportive community of peers, plus structured group and private coaching so you never feel alone.

Measure results
Regular re‑testing and check‑ins make sure your plan is working. Adjustments are made based on your data and your experience, not guesswork.
Why We’re Different
Real clinicians, not software. While many online services solely rely on AI to interpret labs and create canned, one-size-fits-all treatment plans, with Thyroid Authority you will always have a licensed provider and a personal coach overseeing your case. We are LegitScript‑certified for compliance and only recommend evidence-based labs and natural interventions.
Specialists in complex cases. We routinely work with “Hail‑Mary” cases—people who have seen multiple doctors without answers. Many of our clients have been told “it’s all in your head” even though Hashimoto’s and hypothyroidism are well‑documented disorders. We are experienced with thyroid-adjacent conditions like MCAS, POTS, other autoimmunities, hormone imbalances, GI disorders, and chronic fatigue.
Designed for busy women. Our remote model means no long trips to clinics. You are able to attend appointments virtually and most tests are shipped conveniently to your home. You will never be rushed—our team devotes the time needed to understand your full story.
We educate your loved ones. Chronic illness affects families. We provide resources and group calls for spouses and partners so you get the support you need at home.
Integrity and transparency. We don’t accept insurance because insurance often dictates care. Instead, we offer transparent pricing and payment plans, and we refund deposits when a candidate isn’t a good fit.
Our Promise
You’re not “crazy” and you’re not alone. Whether you’re in your thirties, forties, fifties, or beyond, whether you’ve just been diagnosed or have been searching for answers for years, we’re here to help.
By addressing the root causes of your thyroid dysfunction, we aim to give you the energy to be present with your loved ones, the clarity to thrive at work, and the confidence to enjoy your life again.
Our work is about hope—and real results.
