T3 only dosing please help: Hi everyone, its been... - Thyroid UK
T3 only dosing please help


Think we need blood results to see what your current levels are before we can suggest how to adjust or t4 and t3.
Probably swapping over gradually would be more gentle, or trying a different NDT that suits you better.
I swap ratios between summer & winter, & feel best doing this over a month or so in spring & autumn.
Without test results, including ranges, it is impossible to suggest dosage.
Poor conversion is indicated by high FT4 and low FT3, many of us have a thyroid genetic test which will show, or not, the Dio2 polymorphism which can impair conversion but FT tests suffice unless you wish to know if the cause is heterozygous of homozygous....the latter impairs conversion more than the former.
For good conversion vit D, vit B12, folate and ferritin need to be optimal.
As you will know T3 is a very potent hormone and needs to be treated with respect.
Are you possibly overmedicating?
Are you changing doses too frequently...it takes about 6 weeks for the body to adjust to a dose change?
I'm afraid we need to see TSH, FT4 and FT3 results plus those for nutrients listed above.
Suggesting dosage/treatment without those results would not be responsible....or safe.
Please keep us posted.
From previous blood tests your T3 is 62.5% into range so although it could be higher you will need to take care. I think perhaps the below range T4 may not suit you. Perhaps adding a little levo will help. Not everyone does well with low T4. Personally I become unwell in levo only after forty years of ndt. I am a poor convert or having never got beyond 5% into T3 range even on 500mcg of levo. I take 4.5 grains of ThyroidS daily and feel not too bad. Have not had a blood test for about six months. Been on Thyroid S for a couple of months when I could no longer get TR man. It was really easy on digestive system.
We are all very different how were you bloods on previous ndt? Did they show higher T3 and the same under range T4?
Perhaps checking previous results will indicate whether T3 only is best for you. Good luck
Have you read Paul Robinson's books? Very helpful forT3 guidance.
I have labs just was feeling so bad yesterday i didnt post..ill be ppsting all my recent labs today.
