Chaste tree fruit extract (Vitex agnus-castus)

Chaste tree (Vitex agnus-castus) is a Mediterranean shrub whose berries have been used since antiquity in the context of women's health. The standardised extract of its fruits contains diterpenes, flavonoids and iridoids — compounds to which its influence on the hormonal axis is attributed. Clinical studies suggest that this extract contributes to reducing symptoms associated with premenstrual syndrome, such as breast tenderness, irritability and mood changes. Its proposed mechanism of action involves interaction with dopaminergic receptors, which contributes to modulating prolactin secretion and supporting the balance between oestrogens and progesterone throughout the menstrual cycle. Supplementation with chaste tree berry extract is primarily intended for women looking to naturally support their hormonal comfort during the luteal phase. It is generally advisable to use it over several cycles to observe noticeable effects, and the advice of a healthcare professional is recommended when taken alongside hormonal treatments.
