Bioidentical hormones are chemically identical to the hormones your body produces, so they can be absorbed easily and may have fewer side effects than synthetic hormones. EstroGlow and ProGestGlow are considered Bioidentical Hormone Replacement Therapy (BHRT), which are plant-based hormones that are chemically identical to the hormones your body naturally produces.  Traditional hormone replacement therapy (HRT) uses synthetic hormones that don’t possess the same structure as human hormones. Bioidentical hormone therapy is often called “natural hormone therapy” because bioidentical hormones act in the body just like the hormones we produce. Technically, the body can’t distinguish between bioidentical hormones from the ones your ovaries produce.  Bioidentical hormones are made from a plant chemical extracted from yams. These hormones then go through another process in the lab called micronization. ‘Micronized’ means that they are just finely ground in the laboratory for better absorption in the body. Note: The US Food and Drug Administration and The Endocrine Society say there is little evidence to support claims that bioidentical hormones are safer or more effective than synthetic hormones.
