Hi

Does anyone know how much T3 and T4 is in or equivalent to one grain and half a grain of ERFA? I can’t find it online and I feel like I might be overmedicated so want to work out how much of T4 and T3 I’m taking compared to my previous dose.

many thanks

Yes. All the information you could need is in my desiccated thyroid document:

helvella - World Desiccated Thyroid

Contains details of all known desiccated thyroid products including information about several products not considered to be Natural Desiccated Thyroid (NDT/Desiccated Thyroid Extract/DTE).

Thank you, whereabouts is it in the document? I’m struggling to find it.
