Hi Wyn,

Your doc probably doesn't realise that adding T3 to an already large amount of

T4 is not necessarily going to move your FT3 higher.

THe liver uses TSH as one chemical input into the process of T4 to T3

conversion.

Once the TSH is nearing suppression the conversion rate of T4 drops and the FT3

generated from the T4 begins to fall. Yes, you are adding T3 in but you're

losing T3 from the conversion of T4 and gaining rT3 in the process - because the

T4 has to be cleared if it isn't converted to FT3 (or at least the unbound FT4

has to be cleared).

The other thing to watch for is a combination of T4 and T3 that constitute a

supra-physiological dosage. This is a dosage that is too high for the body and

begins to cause problems due to thyrotoxicity (partly due to the active thyroid

hormone and partly due to the high degree of clearance of excess hormones that

you are forcing your body to go through).

The solution to all this is to reduce the T4 before you add any more T3 to the

mix.

I assume you are either taking 15 T3 in the morning and 15 T3 in the afternoon

or 3 lots of 10 mcg T3. Don't take the T3 in one go - this will be a disaster

(for most people).

Lower the T4 would be the solution that normally works. You may find that this

on its own works. However, some people eventually find that they simply cannot

cope with any T4 and drop it totally before using T3. You are a long way from

this decision at the moment.

Cheers,
