- Primary Mechanism
- Dopaminergic action inhibiting prolactin secretion to support luteal phase progesterone synthesis
- Standardized Form
- Fruit extract (standardized to agnusides or casticin)
Vitex agnus-castus, commonly known as chasteberry, is highly effective for female hormonal balance. It operates primarily at the level of the pituitary gland. By binding to dopamine D2 receptors, it inhibits the excess secretion of prolactin. This mild reduction in prolactin helps normalize the luteal phase of the menstrual cycle, naturally supporting the body's own production of progesterone.
