Bio-identical hormone replacement therapy uses hormones that are chemically identical at the molecular level to the hormones your body naturally produces. Derived from plant sources (typically yam or soy), they're processed into the exact structure of human estradiol, progesterone, testosterone, DHEA, or thyroid hormones.
This molecular identity is important: your hormone receptors recognize bio-identical hormones exactly as they do your body's own, unlike synthetic progestins or conjugated equine estrogens, which differ structurally and may carry different risk profiles.
The distinction between "bio-identical" and "synthetic" isn't just marketing — bio-identical progesterone (P4) and synthetic progestins have measurably different effects on breast tissue, cardiovascular markers, and mood in peer-reviewed studies.
At Body Symmetry MD, BHRT protocols are based on comprehensive hormone panels and personalized to your specific levels, symptoms, and goals. We don't use one-size-fits-all dosing — every protocol is calibrated to your biology and adjusted based on follow-up labs and symptom response.
