What Happens When You Stop Taking Phytoestrogen?

Phytoestrogens are plant-based compounds that can mimic or modulate the activity of estrogen, the primary female sex hormone. They are often used as a natural alternative to hormone replacement therapy (HRT) for managing menopausal symptoms such as hot flashes, night sweats, mood swings, and vaginal dryness. However, what happens when you stop taking phytoestrogen? This article explores the effects of discontinuing phytoestrogen supplements and what to expect in terms of women's health, hormone levels, and associated risks.

Understanding Phytoestrogens

Phytoestrogens are found in various foods, including soy, flaxseeds, and red clover. They are often recommended for their potential healthful benefits, such as reducing the risk of breast cancer, improving cardiovascular health, and mitigating menopausal symptoms. These compounds can be found in dietary supplements and are commonly used by postmenopausal women seeking relief from symptoms without the adverse effects sometimes associated with hormone replacement therapy.

Reasons for Stopping Phytoestrogen

There are various reasons why someone might stop taking phytoestrogen supplements:

  • Adverse Effects: Although considered safer than traditional HRT, phytoestrogens can cause side effects like gastrointestinal upset, allergic reactions, or interactions with other medications.
  • Health Concerns: Phytoestrogens, particularly in high doses, have been linked to increased risks of certain health conditions, such as breast cancer.
  • Medical Advice: Some women may be advised to stop phytoestrogen use due to specific health risks or pre-existing conditions.
  • Lack of Effectiveness: Not all women experience relief from menopausal symptoms with phytoestrogens, leading them to discontinue use.
  • Switch to Traditional HRT: Women may switch from phytoestrogens to hormone replacement therapy to manage more severe symptoms.

What to Expect When You Stop Taking Phytoestrogen

Stopping phytoestrogens can lead to a resurgence of menopausal symptoms or other changes. Here’s what you might expect:

Return of Menopausal Symptoms

If you had been using phytoestrogens to manage symptoms such as hot flashes, night sweats, and mood swings, stopping them could lead to a return of these symptoms. The intensity and frequency might vary depending on your body's adjustment to lower estrogen levels.

Impact on Bone Health

Phytoestrogens have been studied for their protective effects against bone loss in postmenopausal women. Discontinuing their use could increase the risk of bone loss or osteoporosis, particularly if no other measures are taken to prevent it.

Changes in Cardiovascular Health

Phytoestrogens are thought to support cardiovascular health, partly by modulating blood pressure and cholesterol levels. Stopping them could affect these protective benefits, so regular monitoring of heart health is advised.

Risk of Weight Gain

Hormone fluctuations can contribute to weight gain, and stopping phytoestrogens might lead to changes in body composition. Maintaining a healthy diet and exercise routine can help manage weight gain.

When to Seek Medical Advice

If you experience severe symptoms after stopping phytoestrogens or have concerns about health risks, it’s essential to seek medical advice. Health professionals can guide you through a proper transition and recommend alternatives to manage symptoms and maintain health. It’s also crucial to discuss any underlying health conditions, risk factors for cardiovascular disease, or concerns about breast cancer risk before discontinuing phytoestrogens.


Stopping phytoestrogens can result in the return of menopausal symptoms and other changes in health. To ensure a smooth transition and maintain quality of life, consult a healthcare provider for personalized advice and alternative treatments. Remember that health outcomes vary, and what works for one person may not work for another, making it critical to have medical guidance tailored to your needs.
