Thyroid: The Overlooked Driver

Most thyroid problems go undiagnosed for years because conventional medicine only tests TSH and misses the full picture. This 33-page evidence-based guide covers the 8 root causes of thyroid dysfunction, the T4-to-T3 conversion problem, natural supplement protocols with confidence ratings, the Armour vs. synthetic T4 comparison, and a complete lab testing guide with optimal ranges. Includes the Dieting-Thyroid Trap section on how under-eating and over-training worsen thyroid function.
