I found the creams a waste of time money and effort. Not really sure why I bothered.
I get (but stopped using once I began ingesting Lugols) a plant based Progesterone tincture from my compounder. Was ordered by my MD (she's a blend - prefers natural approach) due to severe PMS and lack of M's. (No period for five months - corrected ONLY by Lugols) I had originally disliked the notion of sup'ing any hormone, but gave it a try. I have not skipped one period since Feb (Lugols) and no longer notice the insane PMS. Odd but true.
V - do your thoughts on P cream extend to supplementing internally as well?
Only after all that I've read via this forum and links provided have I come closer to thinking that all these hormonal issues might fall back into proper alignment once everything else is in order (halides, metals, minerals, etc.). Perhaps this is why you dismiss Progesterone supplementation?
