I have been on Levothyroxine(100mcg) for a few years now. I decided in February to introduce T3 to see I'd any of my symptoms improved. I am now on 50mcg of Levothyroxine and 50 of T3. My latest blood results have just come back and are as follows.
Serum free T 4. 9.00
Serum TSH. 0.01
Serum T3. 5.7
Do I need to increase my dosage?
Thanks

Can you include the reference ranges? As they differ in different parts of the country, it's not possible to know where your results lie in their ranges so it difficult for members to comment. Also, if you include previous results prior to addition of T3 that will help to see what difference the T3 has made.
FT4 is low because you are taking a proportionately higher dose of T3 than Levothyroxine. FT3 5.7 is usually good but without seeing the range it isn't possible to say whether there is scope to increase dose.
