What is the difference between bio-identical and synthetic hormones?
Technically, there is no difference because bio-identical hormones are synthesized in the laboratory. The key to the differentiation is to ensure that you are taking hormones that are EXACTLY identical to what is produced in your body. Synthetic hormones, as you know them, were invented because Drug companies cant patent a bio-identical or natural chemical compound. Therefore, their synthetic hormones are almost the same as the natural chemical found in your body allowing them to patent and market the drug. Notable examples are Premarin, Prempro and Provera.
