Hello lovely people. This is my first post.
I have an underactive thyroid and hashimotos for 6 years now and have been on levothyroxine only for the last years. Have been prescribed liothyronine by the private endocrinologist.
I started taking teva 10 micrograms plus 100 mg of levothyroxine 6 weeks ago and my t3 is high now and t4 suppressed. Should i reduce my levo dose. I am worried now that i am taking too much. I have attached my recent blood test.
Thank you in advance.
Hi TennisAce and welcome to the forum
It's your TSH that's suppressed 
. This is normal when taking T3, it's just what it does, it lowers FT4 and also lowers TSH to the point of suppression in some people.

It can take a lot of gradual tweaking requiring lots of patience to get the balance of Levo and T3 right for the individual to find your best balance of FT4 and FT3 to feel optimally medicated.
If your reduce your Levo then this will reduce your FT4 level and, possibly to some extent it may reduce your FT3 level as well.
What you need is to lower your FT3 level and you should do this by reducing you T3 slightly and leaving Levo as it is, your FT4 is already low in range and although this may be fine for you it's currently only 31% through range, if you go lower it may be too low for you.
So I would suggest that you try 7.5mcg T3 with your 100mcg Levo and retest in 6-8 weeks to see how you feel and how your levels have changed.
Presumably your key nutrients have been tested and all are at optimal levels:
Vit D - 100-150nmol/L
B12 - top of range for Total B12, if Active B12 is measured then over 100
Folate - at least half way through range
Ferritin - half way through range although some experts say that the optimal ferritin level for thyroid function is 90-110ug/L
Hi SeasideSusie and thank you so much for replying so quick. Really appreciate it.
Thank you for your advice, i will try to reduce it to 7.5. The only problem is i take 20 teva tablet and i cut it in half. They are not very easy to cut those tablets but I will try my best.
Also i will attach my latest vitamins levels.
Do you think i need to improve them.
Thank you again
Do you take any supplements at the moment?
Did you have CRP tested?
No I don't take any supplements at the moment. I used to take the B complex before but i stopped. Should i start taking them again.
I will attach my latest CRP
Thank you
TennisAce
I just wondered if your CRP was elevated, if it was that would suggest inflammation and if so then your Ferritin would likely be raised due to inflammation too. However, your CRP is nice and low so your Ferritin is a good result.
Your B12 is good but Folate is a bit low, would be better in double figures. It might be worth supplementing with a good quality B Complex containing methylfolate, consider Thorne Basic B. Perhaps retest in 3 months to check levels and if Folate has improved enough you could maybe reduce to a maintenance dose a few days a week.
Thank you. Will start taking the B complex and then retest in 3 months.
Was test done early morning, ideally before 9am and last dose levothyroxine 24 hours before test
Last 5mcg dose T3 approx 8-12 hours before test
If taking any supplements that contain biotin important to stop these a week before test
Hi SlowDragon.Thank you for replying so quick.
Yes i did my test first thing in the morning before 9am. And I did take my last dose of T3 in the evening.
Thank you
Just as a “heads up” for the future, if you log into your Medichecks results page you will see an icon at the top right of the page “downloadable PDF” click on the icon and you’ll get your results on one page which you can print off.
