There is some disagreement on which T3 method is the best. Many sources suggest newer formulations of T3 aren’t as effective unless they are crushed and that time release formulas are inadequate. I’m not suggesting anything here except to do your research - multiple times - before trying any treatment. There are some dedicated groups on the internet based around T3 supplementation in add to the Wilson sites:
This site is run by a dedicated group of thyroid patients: thyroid-rt3.com/
…and the thyroid section of this site: eaware.org/thyroid-gland/
This is a non-profit’s site started by the yahoo thyroid forum key members (Endocrine Awareness): eaware.org
Stop The Thyroid Madness: stopthethyroidmadness.com/
These sites have information about base thyroid function along with treatment protocols including Wilson’s variants.
