I've seen the info elsewhere about an enzyme being missing in folks who are

poor converters, but there is some good information in " Thyroid - Guardian of

Health " by Philip Young.

He says in all types of hypo there is a T4 to T3 conversion problem....and

this is one reason hypo folks are not adequately treated. He relates this to

the fact that is known in sickness that there is decreased production of T3

and an increase in Reverse T3. And then says docs are not considering that

hypo is a chronic illness.

He talks about the " second control system " that exists within the cells

themselves..where there is conversion to T3 and Rev. T3. In this system, Type

II

de-iodinase, controls the conversion of T4 to T3.

Interesting enough, he talks about how this enzyme is also inhibited by high

levels of T4....and why T4 levels need to be monitored. too much T4 and you

have depression and mental problems too. One reason why Synthroid patients may

not be doing well as far as depression.

So - you may not have this enzyme - or not in sufficient amounts?

He also talks about a third control which is in the thyroid binding sites

themselves. this is where the thyroid resistance comes in - the body does not

respond to normal amounts of thyroid hormone.
