I wonder if someone would be good enough to cast an eye over my latest blood test results. I am currently on 125mcg Levothyroxine, and 7.5mcg Liothyronine. I take the T3 all at one in the morning, usually around 5am, and the T4 at bedtime. I also take vit d3/k2, haem iron, Thorne basic b , selenium, and zinc.
With regard to my results, my free T4 seems quite low compared to when I was just taking Levothyroxine, and T3 has dropped also since last results. I have been feeling more tired of late, and have had a cold drag on for nearly a month now. Do you think it’s time for an increase in either Levo or Lio, or both?
All blood test protocols were followed. Thank you very much in advance of all replies.

Thanks for your reply. Sorry, I forgot to mention that - I’d actually taken the both my levothyroxine and the whole 7.5mcg dose of T3 24hrs before my test. My Liothyronine is prescribed as capsules, so it’s almost impossible to split the dose the day before. So that probably means my T3 is actually higher than it looks?
Yes that's right, there's a very short half life for T3, and very little after 24 hours.
Definitely looks like you could do with an increase though, as to what though is a matter of opinion. Most will suggest trying to increase your T4 first, and this should hopefully bring your FT3 up somewhat. In your case, this seems most sensible if you can't split the T3 you're on, as a jump of another 7.5mcg T3 might not be tolerated well.
At the moment, Teva for 25mcg, and then I take 2 Hillcross 50mcg. I’ve just upped vit d to 4000 a day, rather than 2000. My ferritin is still pretty low. I take 2 three arrows every other day. My stomach tends to protest if I raise my vitamins too much. Thanks for the advice, I’ll look to up my t4 then. My free t4 was nearing the top of the range when I was on 150mcg previously and was advised to decrease. Maybe try alternate days 125 and 150 to begin with and see how that goes?
Many patients do NOT get on well with Teva brand of Levothyroxine.
Teva is lactose free, but contains mannitol as a filler instead of lactose, which seems to be possible cause of problems. Mannitol seems to upset many people, it changes gut biome
Thanks. I’ll give alternate days a go then. I’ve never noticed a discernible difference between brands, but that doesn’t mean it’s not a factor, so will ask pharmacy to stick to one brand from now on and see if I feel any difference.
