Thyroid T3(Amount of Body)

[BigMatt]

What is the Amount of T3 that is produced in HEALTHY individuals per day?

30 mcg?

 

[Dave_19]

Well the hormone TSH makes the thyroid gland secrete T4 & T3. T4 converts to T3, most circulating t3 comes from 80%+ of T4 conversion. I know plasma levels of t4 are something like 40 times higher than T3. I am not sure in terms of MCG how it would work out but if you were to get a blood test and check T3 the healthy range is somewhere between 200-600pg/dL. A therapeutic dose of t3 ranges also, most take combos of T3/T4 like synthroid. If you were to take a pure form of t3 such as Cytomel a doctor would start you off usually anywhere from 5mcg 1-2x a day - 25mcg, working as high as 75mcg for a maintenance dose. Hope this helps.

T4 to T3 ratios produced in the body are usually 20/1. Medical literature is as follows:

The human thyroid secretes about 80 mcg of T4, 4 mcg of T3, and 2 mcg of rT3 each day. The body converts 30-35% of that 80 mcg T4 to T3. That is 24-28 mcg of T3 ED. Plus the 4 mcg it already produces, average T3 production would be 28-32 mcg ED, in the body.

Thanks guys.

So if i understand ...

That means if Someone who is Hypothyroid( Elevated TSH). Low Free T3.

It will be almost impossible for them to get REALLY LEAN(7%,8%) bodyfat ...

Right?

Someone who has a low thyroid...

So just taking 25mcg is a waste?

not at all, i just got my blood work done a few weeks ago. my t3 has always been normal in all my other test prior to using t3. i was on 25mcg and my test read high 43, normal was 24-39, so 25 mcg does something.

so, does t3 need to be taken twice a day, about 12 hrs apart? seems many people take it once a day, i'm assuming this is incorrect?

It need to be taken 2 times daily.

From what i understand at 12.5 mcg 2 times per day it should be Really safe...

theres plenty of people that been running 75mcg + Per day... So 25 mcg per day shouldnt be a problem.

I am currently running 50mcg x2 a day (6-10 hours apart = 100mcg a day total for 8 weeks.
