Enzymatic Therapy Protective Breast Formula is a must for any woman who is concerned about her breast health. It also helps relieve some of those annoying peri-menopausal symptoms. I am a Breast Cancer Survivor. This supplement was recommended to me by my acupuncturist and I have taken it for 5 years with the support of my oncologist. I did not want to take medication as part of my recovery, but opted for a healthy diet and exercise program. Protective Breast Formula is a part of that program. I have been cancer free for over 5 years now. There is plenty of research behind this product which was developed by surgeon and breast cancer advocate Dr. Christine Horner.
