The Active Ingredient Is: Chasteberry (Vitex agnus-castus) Whole fruit

Chasteberry, from the berry of Vitex agnus-castus, is an herb used traditionally to support women’s hormonal balance. This form uses the whole fruit, providing the naturally occurring compounds such as flavonoids and phytoestrogens.

This product provides whole-fruit chasteberry as its active ingredient, emphasising the complete spectrum of naturally occurring constituents rather than isolated extracts. Inactive components include capsule material and standard excipients.

What Does Chasteberry Do?

Chasteberry helps support the body's natural hormone regulation by modulating the hypothalamic-pituitary-ovarian axis, with phytoestrogens that may influence estrogen and progesterone balance. This aligns with traditional use and is described in scientific resources as supporting hormonal balance in women.

EFSA-aligned information and NHS/NCCIH discussions indicate that such mechanisms work to support normal physiological function rather than introducing synthetic hormones.
