Equivalent dose of t3

I've been trying for a while to find my optimal dose of t3. I take 5mcg X 3 times/day and levo in the morning, so I have 15 mg of T3 in my body/day. I wonder if this is equivalent to taking the full dose once/day ( in the morning), does it have the same effect?

I tried to take the whole dose at once but it didn't work, too much anxiety and heart problems occur.

It is what suits. A single dose of t3 peaks about 4 hours after you take it and is at its lowest about 8 hours after you take it. That is why some folks split t3 through the day. Others are happy with a single dose.There are no rights or wrongs.

Personally I could never tolerate a full dose of levo and have also always split my levo dose.

I take one daily dose of 25mcg T3 when I get up. One dose should last between 1 to 3 days. I know mine lasts for three days as I have trialled it, i.e one 25mcg T3 - none on day two and three. So I now take one daily dose when I get up in the morning and wait an hour before eating.

Many of us need to take T3 as small split doses.

It’s what suits you as an individual

Hi Adin, I take my t3 10mcg at 8 am and my second dose at 2pm every day which equals 20mcg. I tried taking it all at once but it didn’t workout for me it made me very sick but spacing it at least 5 hours apart seems to be my magic number so maybe try playing with twice a day and see how it works for you. I tend to need more energy in the morning but everyone is different. Good luck !

Thank's for the reply, so the total dose(20T3) not cause you anxiety or heart rhythm disorders? Do you take levothyroxine, too?

Yes total 20mcg t3 and levothyroxine 37mcg. So at 8am 10mcg lio with 37mcg levothyroxine and at 2pm just the 10 mcg lio.

Ok, I understand. Your levo dose is small, I'm on 125 mcg Tirosint and I did not reduce it when I added t3.

Yes my levothyroxine dose is small I seem to need more t3 than t4 my body loves the t3. Good luck it’s definitely trial and error.
