Can You Take Black Cohosh and Vitex / Chasteberry Together?

Dose or timing may matter

The short answer

Black Cohosh modulates estrogen receptors while Vitex influences pituitary hormone output (LH, FSH, prolactin). Concurrent use may produce unpredictable hormonal modulation.

How to arrange timing

Consider consulting a healthcare provider before combining these two hormonal modulators.
