VITEX AGNUS-CASTUS Dosing
The following doses have been studied in scientific research:
- For premenstrual dysphoric disorder (PMDD): 20-40 mg of vitex agnus-castus extract taken daily for 8 weeks has been used.
- For premenstrual syndrome (PMS): A specific extract known as BNO 1095 (Agnucaston/Cyclodynon, Bionorica AG), which contains 4 mg of vitex agnus-castus extract has been taken daily for three menstrual cycles. Another specific extract known as Ze 440 (Prefemin, Max Zeller Sohne AG, Romanshorn, Switzerland) which contains 20 mg of vitex agnus-castus extract has been taken daily for three menstrual cycles. Another specific product (Femicur, Schaper & Brummer GmbH & Co. KG, Salzgitter, Germany) containing 6.4-12 mg of vitex agnus-castus extract has been taken daily in two divided doses for three menstrual cycles.
