What Are Bioidentical Hormones? Separating Fact from Fiction

Understanding Bioidentical Hormones

You’ve probably heard about bioidentical hormones, but what are they exactly? Are they safer or more natural than traditional hormone therapy? Let’s break it down.


Bioidentical Hormones vs. Traditional Hormone Therapy

Bioidentical hormones are hormones that have the same chemical structure as those produced naturally by the body. They are used in menopause treatments to relieve symptoms like hot flashes, night sweats, and vaginal dryness.

Many FDA-approved hormone therapy (HT) products are bioidentical, meaning they match the body’s natural hormones. These include:

  • Estradiol (available in pills, patches, creams, gels, and sprays)
  • Micronized progesterone (prescription form of progesterone)

Some pharmacies also create custom-compounded bioidentical hormones, which are mixed to a doctor’s specifications. However, these are not FDA-approved and are not tested for safety, consistency, or effectiveness.


Are Bioidentical Hormones Safer?

There is no evidence that bioidentical hormones—whether FDA-approved or custom-compounded—are safer than traditional hormone therapy. The risks and benefits are generally the same.

Concerns with Custom-Compounded Bioidentical Hormones:

  • Lack of regulation: They are not tested for consistency, purity, or effectiveness.
  • Incorrect dosages: Some products may contain too much or too little hormone.
  • Higher cost: Many insurance plans do not cover custom-compounded hormones.

FDA-approved bioidentical hormones, on the other hand, are tested for safety and effectiveness.


Should You Consider Bioidentical Hormones?

If you are interested in bioidentical hormones, talk to your doctor about FDA-approved options. These are well-studied and available in various forms, allowing for personalized treatment without the risks of unregulated products.
