Bioidentical vs. Natural Hormones

While the terms "natural" and "bioidentical" are often used to describe hormones, they have some key differences. Winona's HRT treatment options are made with bioidentical hormones derived from plants.

Bioidentical hormones are identical in chemical and molecular structure to the hormones that are produced naturally in the body. These hormones are created through a process that extracts and purifies hormones from plants to produce a hormone identical to the one naturally produced in the human body on a molecular level.

Additionally, bioidentical hormones are micronized, so they are better absorbed and utilized by your body. They closely mimic the hormones your body produced for years before you enter the menopause transition.


Bioidentical hormones have been shown to be safe and effective in treating menopause symptoms and other hormone-related conditions because they are more compatible and have fewer side effects.

Natural hormones refer to substances derived from natural sources, such as plants, animals, and minerals. However, "natural" does not always mean "bioidentical."

For example, Premarin, an estrogen derived from pregnant mare urine, is natural, but it is not bioidentical to human hormones.
