The more I read about the importance of B2, and sufficient thyroxine to activate it, the more I wonder what happens for those of us who take exogenous T3 and have suppressed T4 levels?
My T4 levels are usually at a trace amount. I have tried switching to NDT, and even tried going mostly off of T3 meds to let my T4 levels come up. Even when I was on a minimal T3 dose (12 mcg per day) my T4 level stayed suppressed. When I took NDT, my body never seemed to take up the T4 and use it.

How does low T4 affect B2 transport for those of us on T3 meds?
