How it works
Vitex extracts bind pituitary D2 dopamine receptors, lowering modestly elevated prolactin. This shifts the FSH/LH/progesterone ratio in the second half of the cycle, reducing PMS symptoms.
Who should take it
Women with classic PMS or PMDD, cyclical breast tenderness, or short luteal-phase symptoms. Use for at least 3 cycles to evaluate.
Avoid / careful
Avoid with dopamine agonists. Coordinate with hormonal contraceptives (theoretical reduced efficacy). Stop before IVF stimulation.
