I have a friend (used to be one of my students) who is like a daughter to me. She has been going through tremendous stress and suffering with anxiety. She has had testing recently and found her estogen levels are quite low. Other hormones too. She is a petite woman, kind of on the thin side. She says when she first became vegan, she didn't have menstrual periods for 2 years. She has been researching this and says she discovered that vegans have low estrogen, on the average. I haven't come across this before. What would you suggest I might say to her to help her. I wish she could have a consultation with you but her finances wouldn't handle it.
