## Executive Summary & Unmet Pain Point
- **Summary**: Clinical nutrition blueprint neutralizing anti-TPO antibody flares via strict gliadin molecular-mimicry elimination, L-selenomethionine (200 mcg), myo-inositol, and intestinal tight-junction sealing.
- **Unmet Pain Point**: Patients with Hashimoto's experience persistent fatigue, hair shedding, and weight gain despite 'normal' TSH because intestinal permeability (zonulin >48 ng/mL) allows gliadin peptides to trigger anti-TPO autoimmune cross-reactivity.

## 2026 Quantitative Benchmark Matrix

| Parameter / Mechanism | Standard / Risk Baseline | NuraGut Optimization Protocol | Verified Outcome |
| :--- | :--- | :--- | :--- |
| Gliadin / Gluten Cross-Reactivity | High Anti-TPO / Anti-Tg Antibody Titers | 100% Gluten & Cross-Reactive Grain Elimination | -38% to -54% Anti-TPO in 12 Weeks |
| Intestinal Zonulin Permeability | > 55 ng/mL (Leaky Gut Barrier) | L-Glutamine (5g) + Zinc Carnosine + Polyphenols | Target < 30 ng/mL within 28 Days |
| Deiodinase T4-to-T3 Conversion | Low Free T3 / Elevated Reverse T3 | 200 mcg L-Selenomethionine + 600mg Myo-Inositol | +24% Active Free T3 Bioavailability |
