What is the body's natural level of T3?

[Luke]

After what dose of mcg/day is the T3 level higher than the daily produced one? E.g. 12mcg per day, might not make any dif. cause it's close to natural, but 150mcg/day is way above the normal T3 level...

Any ideas?

Thx.

According to EndocrineWeb, your Free T3 level should be between 230-619 pg/d. Since everyone's body is different, the only way you'll be able to tell what a certain dosage will do to your levels of T3 is to take a dosage for a period of time, then have your Free T3 tested.

Here's a link to some good info:
