What Are Bioidentical Hormones?

Bioidentical hormones are custom-blended formulas that contain different hormones that are chemically similar to those naturally made by your body. Bioidentical hormones are either prescription or over-the-counter products that are marketed as being suit a woman’s individual hormones needs, usually determined through saliva hormone testing.

Are bioidentical hormones safer and more effective?

Manufacturers of bioidentical hormones are claiming that these custom-blended hormones are safer than standard, FDA-approved hormone therapy.

Because they are custom-blended and reportedly tailored to suit a woman’s hormone needs, there is a lot of interest in bioidentical hormones. However, according to Mary Gallenberg, M.D., there is currently no evidence that bioidentical hormones are safer or more effective than standard hormone replacement therapy.

Risks of bioidentical hormones

The North American Menopause Society says that custom-blended compounds may offer certain benefits such as individualized dozes and combinations of products and forms that are not commercially available.

However, bioidentical hormones also pose risks. These compounds have not been approved by the US Food and Drug Administration – which means they have not yet been tested for safety, efficacy, potency, and purity. Bioidentical hormones may also contain unknown contaminants.

These are just some of the reasons why the NAMS does not recommend custom-blended bioidentical hormones to menopausal women. Instead they recommend standard, tested, government-approved commercial hormone products for the majority of women.

Bioidentical estrogen and progesterone are available in FDA-approved hormone therapy products such as and Natural progesterone (Prometrium). Both products are available in different doses and forms, thus you won’t have to use unregulated compound products as your natural hormone source.
