Vitex (Chasteberry)

Vitex, also known as chasteberry or Vitex agnus-castus, is an herbal supplement derived from the fruit of the chaste tree that has been used for centuries to support women's hormonal health and menstrual regularity. It works primarily by influencing the pituitary gland to normalize the LH-to-FSH ratio and support progesterone production, which can help regulate menstrual cycles and improve ovulation in some women with PCOS. While vitex may benefit women with mild hormonal imbalances, it should be used cautiously and under professional guidance in PCOS, as its effects on hormone signaling can interact with fertility medications and hormonal treatments.
