Bioidentical hormones are defined as man-made hormones that are very similar to the hormones produced by the human body. These are then used as treatment for men and women whose own hormones are low or out of balance.
Traditional vs. bioidentical
Bioidentical hormones are different from those used in traditional hormone replacement therapy (HRT) in that they’re identical chemically to those our bodies produce naturally and are made from plant estrogens. The hormones used in traditional HRT are made from the urine of pregnant horses and other synthetic hormones.
Supporters of bioidentical hormones claim their products are safer because they are “natural” and identical in makeup to the hormones the body produces naturally. But most experts believe the risks of BHRT and HRT are similar. Compounded bioidentical hormones may carry even more risks. There’s no credible evidence that BHRT is more effective than HRT.
