Thyroid & Hashimoto's Your labs say fine.
Your labs say fine.
You don't feel fine.
If you're still exhausted, foggy, and gaining weight on thyroid medication — while being told your TSH is “normal” — there's usually more to the story. We look at the full thyroid picture and the gut, adrenal, and nutritional drivers behind it.
The short version: A “normal” TSH only tells part of the story. Many people with hypothyroidism or Hashimoto's still feel unwell because no one has looked at their free T3, reverse T3, antibodies, or the gut and nutritional factors driving their symptoms. We test the full picture and build a root-cause plan — without defaulting to a lifetime of medication as the only answer.
Understanding thyroid & hashimoto's
Hypothyroidism and Hashimoto's are some of the most common — and most commonly mishandled — conditions we see. A standard workup often stops at TSH, but TSH is a pituitary signal, not a direct measure of how much active thyroid hormone (free T3) is reaching your cells. People can have a “normal” TSH and still feel exhausted, foggy, cold, and unable to lose weight because of poor T4-to-T3 conversion, elevated reverse T3, nutrient deficiencies, or an autoimmune attack no one has tested for.
Our approach is to map the whole system. We look at the full thyroid panel alongside the gut, adrenals, blood sugar, infections, and key nutrients — because thyroid symptoms are frequently driven by problems upstream. From there we build a personalized plan of nutrition, targeted supplementation, and lifestyle change. The goal isn't to mask symptoms; it's to address why your thyroid is struggling in the first place.

Thyroid & Hashimoto's — common questions
Why do I still feel bad on levothyroxine if my TSH is normal?
TSH is a single pituitary signal — it doesn't show how much active thyroid hormone (free T3) is reaching your cells, whether you're converting T4 to T3, or whether antibodies are attacking your thyroid. We test the full picture, which often explains why you feel unwell despite a “normal” TSH.
Can Hashimoto's be treated naturally?
Hashimoto's is autoimmune, so the goal is to calm the immune attack by addressing its drivers — gut health, food triggers, infections, nutrient deficiencies, and stress. Many patients reduce symptoms and return to a normal life. We don't promise cures; we find and address root causes.
Do I have to stop my thyroid medication to work with you?
No. We never tell you to stop a prescription. We focus on the underlying drivers behind how you feel.
Is this an endocrinologist's office?
No. We're a functional-medicine practice offering a root-cause second opinion. Drs. John & Alexa Parker are chiropractic physicians with advanced functional-nutrition training — not endocrinologists.
