Winning the battle against estrogen 'C'. This supplement naturally removes unwanted estrogen from the body. I took 5 pills a day for first 6 months now maintenance is one in a.m. and one in p.m. Estrogen blockers the Oncologist have block ALL estrogen to essential organs that need it: heart/brain/bones, etc. Body has to have estrogen to function, blockers don't get rid of the estrogen, just block it so you have to stay on it for 5 - 10 years until the 'C' is supposedly dead. Does it really ever die, once off the blockers which for me had undoable side affects, it very well may come back. This supplement helps rid it from the body and can be used with any therapy you choose to fight this pestilence. Also, fully cooked carrots rid bad estrogen from body so include eating them daily in your battle as well. No sugar or any other sweetener except green stevia powder. It helps you in this battle as well. Don't give in, keep up your battle. Your life is worth it and having a quality of life while doing so very important!!!
