Vitex (Chasteberry)

Herbal Supplements

Vitex agnus-castus, commonly known as chasteberry, is a fruit extract with a long history of traditional use for supporting women's hormonal health. Research suggests that vitex may influence the pituitary gland and help modulate levels of prolactin and other hormones involved in the menstrual cycle, which is why it has been widely studied in the context of PMS relief, cycle regularity, and fertility support. Several clinical trials indicate that vitex supplementation may reduce common premenstrual symptoms such as breast tenderness, mood changes, and bloating, with some studies also exploring its potential role during the menopausal transition. While the body of evidence is promising, results can vary, and the mechanisms behind its hormonal activity continue to be an active area of scientific investigation.
