Understanding Chasteberry: A Natural Approach to Managing PMDD

What is PMDD?

Premenstrual Dysphoric Disorder (PMDD) is a severe, hormone-related mood disorder that affects 3–8% of menstruating individuals. Symptoms such as depression, irritability, mood swings, and physical discomfort tend to intensify during the luteal phase (the week before menstruation) and resolve shortly after bleeding begins. At Alpine Psychiatry, we offer a range of integrative treatments—including supplements like Chasteberry—to help manage PMDD’s emotional and physical burden.

What is Chasteberry?

Chasteberry (Vitex agnus-castus) is a fruit extract long used in herbal medicine to support hormonal balance. It influences dopamine activity and modulates prolactin levels, which may help regulate mood and menstrual cycles. While not FDA-approved, it’s widely used as a dietary supplement and supported by clinical research for PMDD and other menstrual conditions.

How Effective is Chasteberry for PMDD?

Emerging research suggests Chasteberry may be as effective as conventional treatments like fluoxetine (an SSRI) and oral contraceptives in alleviating PMDD symptoms—with fewer side effects. A systematic review and meta-analysis found that Chasteberry outperformed other natural options like magnesium, vitamin B6, St. John’s Wort, and vitamin E in improving PMS-related mood and physical symptoms .

At Alpine, we often incorporate evidence-based botanical supplements alongside functional lab testing and medication management when needed.

Recommended Dosage for PMDD

For PMDD, Chasteberry is typically dosed at 400 mg per day, taken in the morning to help stabilize hormone levels throughout the day. Consistency is key; benefits may take several cycles to fully emerge.

Possible Side Effects

Chasteberry is generally well tolerated, but some individuals may experience:

• Mild nausea

• Headache

• Digestive upset

• Skin itching or rash

Important Precautions

Before starting Chasteberry, consider the following:

• Avoid during pregnancy or breastfeeding

• May interact with hormonal birth control or hormone replacement therapy

• Consult your provider if you're taking dopamine agonists or medications affecting the hypothalamic-pituitary axis

At Alpine Psychiatry, we guide patients through safe and personalized supplement strategies based on their full clinical picture.

Other Potential Benefits

While best studied for PMS and PMDD, Chasteberry may also support:

• Menopause symptom relief

• Fertility in select cases

• Prolactin balance in menstrual irregularities

However, more research is needed for these off-label uses. We evaluate supplement options on a case-by-case basis as part of our holistic psychiatric care.

Is Chasteberry FDA Approved?

No. Chasteberry is sold as a dietary supplement, not an FDA-approved medication. That means product quality can vary widely. We recommend using reputable brands that conduct third-party testing for purity and potency.
