I'm not critical of the use of progesterone when indicated but remember the immediate precursor is an OTC supplement in the US and some other countries--pregnenolone.
A dear friend who had a list of AF symptoms liked a combo that included both pregnenolone, progesterone cream, low dose DHEA and also low dose hydrocortisone medication. The combo plus various amino acids, magnesium, low dose lithium supplement, ets and Cutler protocol heavy metal detox was wonderful for her life limiting PTSD.
I too like a little pregnenolone and dhea. we both have worked with an integrative doctor who does followup testing from time to time. Hormones are powerful and so can bite us if we abuse them.
