Some commonly prescribed estrogens and progesterones are bioidenticals, such as Estrace (estradiol). There's a major difference between custom-made formulations and commercial products. Commercial products are regulated and tested for purity and potency, but compounding pharmacies are not.2

    The most important fact to remember about taking bioidentical hormones is that the risks are not yet well understood. They may have the same breast cancer, stroke, blood clot, heart disease, and dementia risks that synthetic hormone therapy has.1
