Here's what they're missing: TSH alone doesn't tell the whole story.
TSH measures how hard your pituitary gland is working to stimulate your thyroid. It says nothing about whether your thyroid hormones are being converted properly, whether your body is using them effectively, or whether autoimmune thyroiditis is silently destroying your gland.
Naya uses a different approach. We run a comprehensive thyroid panel because thyroid dysfunction comes in many forms—and they all need different treatment strategies.
Even one or two of these symptoms warrant a complete thyroid workup—not just TSH.
At Naya, we test the complete thyroid panel to understand how your thyroid is functioning:
Pituitary-thyroid communication
Circulating thyroxine available to tissues
Active thyroid hormone at cellular level
Blocking T3, often elevated in stress
Autoimmune thyroiditis marker
Additional autoimmune marker
We use evidence-based optimal ranges—not generic lab reference ranges—to determine if your hormones are where they need to be for you to feel your best. For example, an "in-range" TSH of 2.5–3.5 might be optimal for many patients, while others feel best with TSH under 1.5. We find your individual optimum.
Once we understand your thyroid picture, treatment is tailored to your needs. Common options include:
The most prescribed thyroid medication. Best for patients who convert T4 to T3 efficiently. We start low and adjust based on symptoms and labs, not just TSH.
For patients who don't feel well on T4 alone despite normal labs—often due to poor T4-to-T3 conversion. Combining both hormones improves symptoms and quality of life.
A time-tested option containing both T3 and T4 in natural ratios. Options include NP Thyroid, Armour Thyroid, and other brands. Some patients respond better to DTE than synthetic hormones.
For patients with sensitivities to fillers or who need a specific T3/T4 ratio. Custom-compounded thyroid medications offer personalization.
All treatment is backed by current evidence and adjusted based on how you feel, your symptoms, and your lab results.
Yes, when done properly. Thyroid replacement therapy has been used safely for over 100 years. Safety depends on three things:
Side effects from thyroid medication are rare when dosed appropriately. Under-dosing leaves you symptomatic. Over-dosing can cause anxiety, rapid heart rate, or insomnia. We find your sweet spot.
TSH alone only measures pituitary function, not thyroid hormone availability. A comprehensive panel includes Free T3, Free T4, Reverse T3, TPO antibodies, and thyroglobulin antibodies—giving a complete picture of thyroid function and autoimmune activity. Many patients have normal TSH but poor T3 levels, elevated Reverse T3, or undetected antibodies causing their symptoms.
Yes, absolutely. Many patients have normal TSH but still experience fatigue, weight gain, and brain fog due to poor T4-to-T3 conversion, elevated Reverse T3, or undetected thyroid antibodies. Naya tests the full panel using evidence-based optimal ranges, not just standard lab reference ranges. This reveals dysfunction that standard testing misses.
Treatment is personalized based on your testing and response. Options include levothyroxine (T4), combination T3/T4 therapy, desiccated thyroid extract (Armour/NP Thyroid), and custom-compounded formulations. We choose based on your conversion efficiency, symptoms, and preference.
When properly dosed and monitored, thyroid replacement therapy is safe and effective. Naya uses evidence-based dosing, symptom evaluation, and regular testing to optimize outcomes and minimize side effects. We adjust as needed to find the dose that makes you feel best.
No. Thyroid optimization is for anyone experiencing thyroid-related symptoms—fatigue, weight gain, brain fog, hair loss—regardless of conventional lab results. Naya takes a functional medicine approach focused on how you feel and your evidence-based optimal ranges, not just hitting a reference range.
