T3 sufficiency
How do we get enough T3 into thyroid hormone receptors?
In thyroid disease and therapy, even when TSH is normalized, we can still be genuinely hypothyroid if we do not have enough T3 getting into our thyroid hormone receptors in cells throughout the body. Most people know there’s two ways… Read More ›

Deiodinase Type 3, not RT3, plays the T3-blocking role
Well-meaning people have attributed to the hormone Reverse T3 (RT3) a “T3-blocking” function. However, the enzyme deiodinase type 3 (D3) is the main blocker of T3 hormone. D3 is the enzyme that rises to dominate in states of severe illness… Read More ›
Visualizing thyroid hormone activity in cells: T3 and RT3 in context
I’ve recently been inspired by an visual of thyroid hormone cellular action published by Bianco and colleagues in September, 2019. This visual has taught me a new way of seeing these hormones’ pathways of movement and activity in our bodies…. Read More ›

There’s a deep lie behind today’s TSH-based definition of “euthyroid” status and today’s policies of TSH normalization in therapy. The lie is that the loss of the thyroid and the initiation of thyroid hormone dosing has NOT altered and skewed… Read More ›
