Thyroid Optimization in Denver & Alamosa, CO
Most conventional thyroid panels only check TSH — and miss the full picture. At Defiance Health, we run comprehensive thyroid panels including Free T3, Free T4, Reverse T3, and thyroid antibodies, so we can identify dysfunction that standard labs routinely overlook.
Whether you have Hashimoto's thyroiditis, hypothyroidism, subclinical thyroid disease, or are simply exhausted and gaining weight with a "normal" TSH, our providers will dig deeper to find the root cause and build a treatment plan around you — not around a number on a lab report.
What We Test
Hypothyroid Symptoms Are Often Dismissed
Thyroid dysfunction is one of the most underdiagnosed conditions in medicine. Millions of people — especially women — are told their labs are "normal" while continuing to struggle with symptoms that are anything but normal.
Thyroid Conditions We Diagnose & Manage
The thyroid is a small butterfly-shaped gland in your neck that controls nearly every system in your body — metabolism, energy, mood, heart rate, temperature regulation, and more.
Hypothyroidism
The thyroid doesn't produce enough hormone. Classic symptoms include fatigue, weight gain, cold intolerance, and brain fog. Often undertreated when only TSH is checked.
- Primary hypothyroidism
- Secondary hypothyroidism
- Subclinical hypothyroidism
- Post-thyroidectomy management
Hashimoto's Thyroiditis
An autoimmune condition where the immune system attacks thyroid tissue. Often missed because TSH can appear normal early on.
- TPO & thyroglobulin antibody testing
- Anti-inflammatory dietary support
- Gut health & immune optimization
- Hormone stabilization
Reverse T3 Dominance
Your body converts T4 into Reverse T3 instead of active Free T3 — causing hypothyroid symptoms even when TSH looks fine.
- Triggered by chronic stress or illness
- Calorie restriction & crash diets
- Iron deficiency & nutrient depletion
- Addressed with T3 therapy when appropriate
Subclinical Hypothyroidism
TSH is elevated but T3 and T4 are still in range. Conventional medicine often takes a "watch and wait" approach — but patients are frequently symptomatic.
- TSH between 2.5–10 mIU/L
- Symptom-based treatment decisions
- Cardiovascular & cholesterol implications
- Fertility considerations
Poor T4-to-T3 Conversion
Many patients on levothyroxine still feel terrible because their bodies don't convert it efficiently to active T3.
- Liver & gut conversion factors
- Selenium & zinc deficiency
- Combination levothyroxine + liothyronine
- Natural desiccated thyroid (NDT)
Thyroid & Hormone Overlap
Thyroid dysfunction rarely occurs in isolation. Low estrogen, progesterone, testosterone, and adrenal dysfunction all impact thyroid function.
- PCOS & thyroid connection
- Menopause & thyroid changes
- Low T & thyroid in men
- Adrenal fatigue & HPA axis
A Normal TSH Doesn't Mean a Healthy Thyroid
TSH is the only marker checked by most PCPs. It's a pituitary signal — not a direct measure of how much active thyroid hormone is reaching your cells. You can have a perfectly "normal" TSH and still have:
- → Low Free T3 — the only hormone your cells actually use
- → Elevated Reverse T3 blocking your T3 receptors
- → Positive TPO antibodies indicating Hashimoto's
- → Poor T4-to-T3 conversion due to nutritional deficiencies
At Defiance Health, we use functional reference ranges — not just the lab's broad "normal" ranges — and we treat the patient in front of us, not just their numbers.
Functional Reference Ranges
We target optimal Free T3 levels (upper third of the range), not just "not low."
Symptom-Driven Decisions
Numbers inform — they don't dictate. If you have classic hypothyroid symptoms and borderline labs, that matters.
Direct-Pay, No Gatekeeping
No referral required. Full thyroid panel, results review, and treatment plan in a single appointment.
Comprehensive Thyroid Lab Panels
We don't order one marker and call it a day. Our thyroid panels give us a complete picture of how your thyroid is functioning — from pituitary signaling all the way to cellular delivery.
Core Thyroid Panel
Our baseline thyroid panel goes beyond TSH to measure actual circulating hormone levels.
Hashimoto's / Autoimmune Panel
If Hashimoto's is suspected, we add TPO and thyroglobulin antibodies to confirm autoimmune thyroid disease.
Full Hormone + Thyroid Panel
Thyroid function is deeply connected to sex hormones and adrenal output. This bundled panel uncovers the full picture.
Nutrient & Conversion Factors
All required for proper thyroid hormone production and T4-to-T3 conversion. Deficiencies are extremely common.
Thyroid Treatment Tailored to You
There is no one-size-fits-all approach to thyroid treatment. We find what works for your body — not just what's easiest to prescribe.
Levothyroxine (T4 Therapy)
The most commonly prescribed thyroid medication. Works well for patients who convert T4 to T3 efficiently. We dose to target optimal Free T4 levels, not just TSH suppression.
Combination T3/T4 Therapy
Adding liothyronine (T3) alongside T4 can dramatically improve symptoms for patients who convert poorly.
Natural Desiccated Thyroid (NDT)
Contains both T4 and T3 in a natural ratio. Excellent for patients who prefer a whole-gland approach.
Nutrient Optimization
Selenium, zinc, iron, Vitamin D, and B12 are all essential for thyroid function. We identify and correct deficiencies through diet and targeted supplementation or vitamin injections.
Anti-Inflammatory Support
For Hashimoto's patients, reducing systemic inflammation through diet and lifestyle is foundational.

Thyroid Health Connects to Everything
Thyroid dysfunction rarely exists in isolation. Here are the services most commonly combined with thyroid care.
Bioidentical Hormone Replacement (BHRT)
Low estrogen and progesterone worsen thyroid symptoms. BHRT and thyroid optimization are a powerful combination for women in perimenopause and menopause.
Testosterone Replacement Therapy (TRT)
Low testosterone often co-occurs with thyroid dysfunction. Both cause fatigue, weight gain, and brain fog.
Medical Weight Loss
Thyroid dysfunction is one of the most common causes of weight loss resistance. Optimizing thyroid function is often a critical first step.
Chronic Fatigue & Low Energy
Thyroid dysfunction is among the top root causes of chronic fatigue.
Direct-to-Consumer Lab Testing

Nutrition Coaching
For Hashimoto's patients especially, diet plays a major role in managing antibody levels and inflammation.
Thyroid FAQs
TSH is a pituitary hormone — it tells the thyroid to produce more hormone, but it doesn't tell you how much active T3 is actually reaching your cells. You can have a "normal" TSH and still have low Free T3, high Reverse T3, or Hashimoto's antibodies. The conventional TSH "normal" range (0.5–4.5 mIU/L) is very wide. Many functional medicine practitioners believe optimal TSH is closer to 1.0–2.5 mIU/L. At Defiance Health, we use functional ranges and treat your symptoms, not just your TSH number.
Hypothyroidism is a condition where the thyroid doesn't produce enough hormone. Hashimoto's thyroiditis is the most common cause — it's an autoimmune disease where the immune system attacks thyroid tissue. You can have Hashimoto's for years before your TSH becomes elevated. This is why antibody testing is so important.
Yes — this is one of the most common situations we see. Levothyroxine is T4-only, and many people don't convert T4 to active T3 efficiently. We frequently help patients transition to combination T3/T4 therapy or natural desiccated thyroid (NDT). We also check Reverse T3, which can block T3 receptors. Many patients report dramatic improvement after these adjustments.
Free T3 is the active thyroid hormone that drives metabolism, energy, and cognitive function. Reverse T3 (RT3) is an inactive molecule that occupies the same receptors as Free T3, blocking it from working. High RT3 essentially turns off thyroid function at the cellular level, even when blood T3 looks acceptable. It's commonly elevated in chronic stress, calorie restriction, and low iron.
Yes. We offer telehealth thyroid consultations for patients in Colorado, Arizona, California, and Washington. We can direct you to a local Quest, LabCorp, or Access Medical Labs location for blood draws, review results virtually, and prescribe thyroid medications through telehealth.
Most patients notice meaningful improvement within 4 to 8 weeks. Energy and mood improve first. Weight, hair, and skin changes take 3 to 6 months. We retest labs at 6 to 8 weeks to confirm optimization.
No referral is needed. We operate on a direct-pay model. Lab costs are billed separately through your lab of choice. We provide superbills for insurance or HSA/FSA reimbursement.
We accept cash, credit cards, HSA/FSA cards, and offer financing through CareCredit and Cherry for patients who want to spread costs over time. Both offer promotional financing with no or low interest for qualified applicants. You can apply for either directly through their websites before your appointment.
Absolutely. The thyroid regulates your basal metabolic rate. When function is low, metabolism slows significantly. Patients often gain 10 to 30 pounds without dietary changes. This isn't a willpower problem — it's hormonal. We often combine thyroid optimization with our medical weight loss program for best results.
Stop Accepting "Normal" When You Don't Feel Normal
If you've been told your thyroid is fine but you still feel exhausted, foggy, and stuck — it's time for a second opinion backed by comprehensive labs and a provider who actually listens.
