Not sure about the first ingredient, but one of the main ingredients is soy bean extract, which contains 40% isoflavones.OP, are you aware that all these tablets might be doing is increasing your estrogen...... like low dose HRT would do, just in a different way. Except, HRT would probably be far more effective and cheaper for you if you stretched out those doses. In some cases soy might lower a women's estrogen.
*I read a book on nutrition for menopause ('happy menopause' iirc) ; here is the distilled essence:
drink water lots
eat protein lots (this helps with adrenal stuff that is affected by meno)
eat veg/fruit lots
less sugar
less refined carbs and carbs*
So....basically try to eat healthily? I'm sure if someone's obese or is just eating far too much sugar and tran fats, this advice would be beneficial anyway.....but I'm doubitng if this would cut the severe symptoms that many averagely healthy women report.
