Thyroid Optimization: Beyond Normal Lab Ranges
Why "normal" thyroid levels might not be optimal, and how functional approaches differ from conventional treatment.
Millions of people with thyroid issues are told their labs are "normal" despite experiencing classic hypothyroid symptoms. This guide explores the difference between normal and optimal thyroid function.
The Problem with Standard Ranges
Standard TSH reference ranges (0.5-4.5 mIU/L) are statistical norms, not optimal ranges. Many patients feel significantly better with TSH levels between 0.5-2.0 mIU/L. Additionally, many doctors only test TSH, missing important markers like Free T3, Free T4, and thyroid antibodies.
Comprehensive Testing
A complete thyroid panel should include TSH, Free T4, Free T3, Reverse T3, and thyroid antibodies (TPO and TG). This provides a fuller picture of thyroid function and autoimmune status.
