    The Thyroid Testing Problem

    Most doctors test only TSH. If it's in the "normal" range, you're told your thyroid is fine. But this single marker misses the full picture.

    The Complete Thyroid Panel

    • TSH — Pituitary signal to the thyroid
    • Free T4 — Inactive hormone your thyroid produces
    • Free T3 — Active hormone your cells use
    • Reverse T3 — The brake pedal that blocks T3
    • Thyroid Antibodies (TPO & TG) — Markers for autoimmune thyroid disease
    • Iodine and Selenium — Essential cofactors

    Root Causes of Thyroid Dysfunction

    Autoimmunity (Hashimoto's)

    90% of hypothyroidism is autoimmune. The trigger is often gut dysfunction, food sensitivities, or infections.

    Gut-Thyroid Connection

    Leaky gut allows proteins into the bloodstream that mimic thyroid tissue, triggering immune attacks.

    Adrenal-Thyroid Axis

    Chronic stress suppresses T4-to-T3 conversion. Related: Burnout recovery.

    Environmental Toxins

    Heavy metals, fluoride, bromide, and endocrine disruptors interfere with thyroid function.

    Our Protocol

    1. Full diagnostic panel including antibodies and nutrient cofactors
    2. Gut healing to address the autoimmune trigger
    3. Targeted supplementation — selenium, zinc, iodine, adaptogens
    4. Stress management — vagus nerve support, meditation
    5. Detoxification — remove thyroid-disrupting toxins
