High T3

[cpj12]

I don’t have a thyroid and only take t3 medication (liothyronine) my last blood indicates high T3 and normal Free T3. I am confused should I lower my dose 75 at 5:30 am and 25 at 11:00 am

Ranges

T3 220. 60-180

Free T3. 4.0 2.3 -4.2

I feel fine no heart paps or jitters that usually come with being hyper

Thanks any thoughts would be greatly appreciated

Here in the UK it's very rare for Total T3 to be tested, only in Scotland it's done I believe, it is an outdated test and not particularly useful. It measures the total amount of T3, both bound to proteins and unbound (free). It's the Free T3 that is available to the cells and this is the more important test. As your Free T3 is within range and you feel fine, then there doesn't seem to be any need to alter your dose.

Thanks so much. I didn’t want to change my dose

How do you normally take your T3

As single dose …or split at 2 or 3 smaller doses spread through the day

Day before test you should split dose into 3 doses and take last 25mcg dose approx 8-12 hours before test

What vitamin supplements are you currently taking

When were vitamin D, folate, ferritin and B12 last tested

What’s reason for your hypothyroidism

Autoimmune thyroid disease (hashimoto’s)

Thyroidectomy

RAI

Had a huge goiter that was on my trachea and growing down into my chest. I split my dose but not 12 hours from testing. I don’t take it in the morning prior to testing. There are about 18 to 19 hours before testing. I take D3, b12 folic acid magnesium b6. Everything you asked about was tested on November 3 and in normal range.

Thanks so much

Please add results and ranges

Was thyroid tested as recommended splitting T3 dose

If you feel well with no symptoms of overmedication then maintaining the status quo is most likely the way to go.

T3- only is the last resort and you really need to concentrate on signs and symptoms/ clinical evaluation.

Current blood tests were nor really designed for T3-only but when on low doses, tests can be useful to check that your FT3 is within range.

However, some of us ( fairly rare) with cellular, rather than glandular, hypothyroidism need high dose T3 with over range FT3

This might explain

paulrobinsonthyroid.com/t3-...

I'm in Scotland and have only once had TT3 tested ....several years ago.

FT3 is the important lab it shows how much unbound ( to protein) T3 is available to reach the nuclei of the cells where it gets to work. Unless it reaches the nuclei of the cells it remains inactive and symptoms will persist.

Using the word " hyper" is misleading when we mean overmedicated.

If you are HYPOthyroid then you cannot physically become HYPERthyroid

I need a high dose of T3-only which I take in a single dose at bedtime and no longer have blood tests, relying instead on clinical evaluation.

Stay well

Thanks. I was referring to feeling hyper. The dose I am on seems to be the best fit for me.

[DippyDame in reply to cpj12]

Yes, I understood that.

I was just offering my thoughts.

So glad you have found your therapeutic dose.

I think this article about rT3 explains its role and importance very well:thyroidpatients.ca/2019/11/...
