Luteal Phase Lengthener
Vitex has a strong ability to regulate the luteal phase of the menstrual cycle. The luteal phase of the menstrual cycle is the second half of the cycle that begins with ovulation and ends with menstruation. A variety of women’s health conditions can occur when the luteal phase is abnormal. Vitex indirectly lengthens the luteal phase by acting on the hypothalamus in the brain. Vitex is understood to increase the secretion of lutenizing hormone (LH) while holding back the release of follicle stimulating hormone (FSH). This results in higher progesterone levels in the body.
