Understanding Chasteberry for PMDD: A Natural Supportive Approach

What Is Chasteberry and How Can It Help PMDD?

Premenstrual Dysphoric Disorder (PMDD) affects approximately 3–8% of menstruating women, causing intense symptoms like irritability, depression, anxiety, and mood swings in the week leading up to menstruation. At Alpine Psychiatry, we explore integrative treatment strategies—including evidence-based supplements like Chasteberry—to support individuals managing hormone-related mood disorders.

Chasteberry (Vitex agnus-castus) is a herbal supplement traditionally used to address menstrual irregularities. Recent research suggests it may offer meaningful relief for PMDD symptoms without the side effects often associated with antidepressants or hormonal contraceptives.

Evidence for Chasteberry in PMDD Treatment

Clinical studies and meta-analyses indicate that Chasteberry may be just as effective as fluoxetine (an SSRI) and oral contraceptives in alleviating PMDD symptoms. One meta-analysis even found it more effective than other natural remedies such as magnesium, pyridoxine (B6), St. John’s Wort, and vitamin E in improving the full range of PMS-related symptoms .

Recommended Dosage and Administration

The typical recommended dose of Chasteberry extract for PMDD is 400 mg daily, ideally taken in the morning to help maintain stable hormone levels throughout the day. Always follow product instructions and speak with a qualified provider before beginning any supplement.

Possible Side Effects

Chasteberry is generally well-tolerated, but side effects may include:

• Mild gastrointestinal discomfort

• Headache

• Nausea

• Itching or rash

If you experience persistent or severe symptoms, discontinue use and consult your provider.

Safety Considerations and Interactions

Chasteberry is not recommended for individuals who are pregnant, breastfeeding, or planning pregnancy. It may interfere with hormonal birth control or hormone replacement therapy, potentially reducing their effectiveness.

If you're on any medication—especially those that affect dopamine or hormones—talk to your prescribing provider or our team before starting Chasteberry. At Alpine Psychiatry, we integrate functional testing and medication management to ensure supplement safety and compatibility.

Other Potential Benefits of Chasteberry

In addition to its role in PMDD care, Chasteberry may also support:

• Fertility enhancement

• Menopausal symptom relief

• Menstrual regulation

While some of these benefits are backed by promising evidence, others require more research.

Is Chasteberry FDA-Approved?

Chasteberry is sold as a dietary supplement and is not FDA-approved for any medical indication. That means its manufacturing is not strictly regulated—so sourcing from high-quality, reputable brands is critical. We recommend patients choose products with third-party testing and avoid formulations with unnecessary fillers.

Final Thoughts

Chasteberry offers a natural, research-informed option for managing PMDD. While not a substitute for professional care, it can be a helpful addition to a broader integrative treatment plan. At Alpine Psychiatry, we support each patient in finding personalized solutions that may include supplements, therapy, functional lab testing, and hormone support.
