Reverse T3

Available as add-on
Why we test it
Reverse T3 is an inactive thyroid hormone the body produces to slow things down, usually during stress or illness. High levels block your body's production of active T3, causing fatigue, sluggish thinking, and weight gain even when standard thyroid tests look normal.
