Progesterone caused a terrible soya food allergy to come on
by Catherine Roberts
I took natural USP progesterone for 2 months in July 2010. By late August I was having digestion problems. This has led to a regular sour stomach due to an extreme reaction to soya. Even soya lecithin used in many commercial products brings this on within minutes. It took me nearly 18 months of suffering to realise that soya was the trigger. I believe soya is the content of natural progesterone which I had applied topically. Be careful everyone it can also cause illness as well as help certain others!
