What Is Estroven?

A Dietary Supplement for Symptoms of Menopause

Estroven is the brand name of a line of dietary supplements that contains a combination of herbal extracts, soy isoflavones, vitamins, and minerals. Since 1997, Estroven products have been advertised as having the ability to ease some of the most frequently experienced symptoms of menopause.

Two main ingredients are found in all Estroven products. One is black cohosh root, a plant found in North America that contains fukinolic acid. Soy isoflavones derived from soybean plants are the other component (ingredient).

This article discusses menopause and its symptoms. It explains how Estroven products may help people during menopause and Estroven's possible side effects.

Dietary supplements are not regulated in the United States, meaning the Food and Drug Administration (FDA) does not approve them for safety and effectiveness before products are marketed. When possible, choose a supplement that has been tested by a trusted third party, such as USP, ConsumerLab, or NSF.

Keep in mind, though, that even if supplements are third-party tested, they aren't necessarily safe for all or effective in general. It is important to talk to your healthcare provider about any supplements you plan to take and to check in about any potential interactions with other supplements or medications.

Uses of Estroven

Supplement use should be individualized and vetted by a healthcare professional, such as a registered dietitian, pharmacist, or healthcare provider. No supplement is intended to treat, cure, or prevent disease.


Twelve months after the final menstrual period, which occurs in people designated female at birth around age 45 to 55, the next part of the reproductive life cycle, called menopause, begins. Estroven is typically used for symptoms of menopause. Symptoms may include hot flashes, vaginal dryness, emotional symptoms, and sleep changes.

Most people enter menopause due to estrogen and other hormone levels in the body naturally decreasing with age. They also may experience premature menopause, which causes these changes earlier in life because of a health condition, medication, or surgery. Removal of the ovaries, or damage caused by chemotherapy, may also cause early menopause. An Estroven formula for premenopausal symptoms also exists.

Menopause symptoms are sometimes treated with hormone replacement therapy (HRT). Clinical studies about the effects of black cohosh on menopause symptoms have shown mixed results.

Soy isoflavones, another component found in Estroven, have also been believed to relieve menopause symptoms. Some clinical data suggest that soy isoflavones reduced menopausal symptoms such as hot flashes, bone health, and lipids. This data is not enough to identify who would benefit from the use of soy isoflavones.

More research is needed to determine if these supplements are safe and effective for treating menopause.

What Are the Side Effects of Estroven?

Information about the side effects of Estroven as a combination product is lacking in clinical study data. There are some known side effects of black cohosh and soy isoflavones, components (ingredients) of Estroven.

Common Side Effects

Most side effects of products containing black cohosh are mild. Black cohosh side effects include:

  • Stomach upset
  • Rash
  • Cramping
  • Headaches
  • Vaginal spotting or bleeding

Potential soy side effects include:

  • Changes in thyroid function
  • Changes in digestion (constipation, diarrhea)
  • Impact on hormone-sensitive cancers, such as breast cancer

Severe Side Effects

There are no reported severe side effects of Estroven. However, there are instances in which black cohosh may have caused liver damage. These cases are rare, and it cannot be sure that black cohosh alone caused the liver disorder.

If you are taking prescription medications or receiving care for a disease, such as chemotherapy for cancer, tell your healthcare provider before taking this or any other herbal supplement.


Because Estroven contains black cohosh, there are precautions to be aware of when using Estroven as a supplement.

Black cohosh is not recommended for use by pregnant or breastfeeding persons. People who are pregnant should speak with their healthcare provider before using Estroven.

Anyone who has an allergy to the ingredients of Estroven should not use it.

It's important to remember that the health benefits and safety of Estroven remain unproven by research studies, the results of which remain mixed.

The U.S. Pharmacopeia, a nonprofit scientific organization that vets supplements, recommends that people with diseases or conditions affecting the liver ask their healthcare provider before taking any supplements that have black cohosh in them.

Use caution with Estroven if you take certain medications like blood-thinners, thyroid medicines, or monoamine oxidase inhibitors (MAOIs).

The effects of high doses of Estroven are unknown and should be avoided.


Estroven comprises many substances that may interact with other supplements, herbs, and medications. Reviewing the use of Estroven with your healthcare provider is best.

Blood-thinning medications: Estroven may interact with blood-thinning medications such as Jantoven (warfarin).

MAOIs: The soy isoflavones in some Estroven formulations may interact with monoamine oxidase inhibitors.
