how are you feeling?

You could increase your still low/mid range . Do you have the Dr Toft book for amazon.co.uk/Thyroid-Disord... cant remember the page but says about getting t4 range to top for relief of symptoms in some people.

FT4 = FREE T4

Thyroid hormones not bound to proteins. FT4 lowers when the thyroid is struggling.
