How are natural hormones different from synthetic hormones?
• Synthetic hormones are made from substances that are not natural in the human body. For example, Premarin is made from a pregnant mares urine. It is important to note that a study on synthetics by Womens Health Initiative of the National Institute of Health was prematurely halted due to deleterious long-term effects on womens health, specifically breast cancer, blood clots, and stroke. Natural hormones are bio-identical to the bodys own hormone molecules.
