Millions of women are prescribed synthetic hormone replacement — synthetic progestins like medroxyprogesterone acetate (MPA) or norethindrone, and synthetic estrogens like conjugated equine estrogen. Many feel no better, or actively feel worse. This is not a coincidence — it is chemistry.
Synthetic hormones are structurally different from the hormones your body produces. Progestins in particular bind to progesterone receptors but also cross-react with androgen, glucocorticoid, and mineralocorticoid receptors. This cross-reactivity is responsible for many of the side effects women report: bloating, mood changes, depression, weight gain, breast tenderness, and reduced libido — all classic signs of the synthetic progestin’s off-target binding.
The landmark Women’s Health Initiative (WHI) study, which found increased risks of breast cancer and cardiovascular events, used synthetic hormones — specifically conjugated equine estrogen and MPA. When the same analysis was applied to bioidentical hormone studies, the risk profile was dramatically different. The KEEPS trial and the French Cohort study both demonstrated that bioidentical estradiol and progesterone do not carry the same risks as their synthetic counterparts.
Bioidentical hormones are molecularly identical to the hormones your body naturally produces. They bind only to their intended receptors. They are processed through normal metabolic pathways. And when prescribed correctly — with proper testing, appropriate delivery methods, and careful monitoring — they restore hormonal balance without the side effect profile of synthetic alternatives.
If you have tried conventional HRT and felt worse, bioidentical hormone therapy may be the approach you have been looking for. Call 844-734-2112 or contact our team to learn more about bioidentical options.
