Bio identical hormone replacement is a new therapy which utilizes bio identical hormones to deal menopausal symptoms and other conditions brought about by declining levels of hormones in the body. These hormones are lab manufactured to have the same chemical and molecular composition and structure as those hormones made by the body. This is one of the things that make them different from synthetic hormones that are unnatural and intentionally made to be different. http://www.ageology.com/
