Is the dose of 7.5 mcg of SRT3 and 62.5 of Synthroid ideal?
7 to 10 days
Noted your concern. Why was T3 started along with T4 ( synthroid) ?
T3 is the active hormone. T4 has to be converted to T3 to act. T3 has fast onset of action, but has a short half life.
Endocrine society doesn't recommend combination of T3 and T4 in most cases. T4 (synthroid) alone would suffice in most cases.
You should start noticing the difference in 7- 10 days after starting T3
Increase Synthroid, rather than adding T3
Did you do the blood tests for Free T4 after taking Synthroid or on fasting? If non fasting sample, how long after taking tablet did you do the blood test. I would rather increase the dose of Synthroid to 88 from 62.5 rather than adding T3. T4 will be comberted to T3 and hence increasing the dose of T4 would naturally optimise the levels of T3 as well. Could you attach the blood reports please ?
