The science behind bio identical hormone therapy is straightforward yet fascinating. Hormones are chemical messengers that regulate vital functions in the body, from metabolism to mood regulation. As people age or face certain health conditions, hormone levels naturally decline, leading to uncomfortable symptoms. Bio identical hormone therapy works by supplementing the body with custom-compounded hormones that match its natural chemistry. These hormones bind to receptors in the body in the same way natural hormones would, restoring balance and easing disruptive symptoms such as hot flashes, fatigue, mood swings, and weight fluctuations.
