Bioidentical hormone therapy is a medical approach involving the use of hormones that are molecularly identical to the hormones naturally produced in the human body. These hormones are typically derived from plant sources and formulated to be chemically identical to endogenous hormones.
Bioidentical hormone therapy originated in response to concerns about conventional hormone therapy, which uses synthetic or equine hormones (derived from pregnant mares) in hormone replacement therapy (HRT) for postmenopausal women. The idea was to provide a more natural and personalized alternative to address hormonal imbalances.
