Thanks for the feedback everyone.
I have been on high protein diets in the past and never noticed that it affected my acne. But I don’t suppose I will ever know specifically what ingredient caused it, sadly.
I do find it interesting that it caused a migraine in someone with hormone imbalance.
I have seen so many studies saying phytoestrogens are beneficial and just as many saying they are not. I guess it depends on your specific hormone profile.
What a minefield it is!
