Black Cohosh and Calcium, a synergy.
Calcium complements black cohosh in the menopausal setting by supporting bone density, which black cohosh does not address while it relieves vasomotor symptoms.

Synergy
What is happening. Calcium complements black cohosh in the menopausal setting by supporting bone density, which black cohosh does not address while it relieves vasomotor symptoms.
Mechanism. Black cohosh targets hot flashes via central neurotransmitter pathways without estrogenic bone protection, so adequate calcium intake helps fill the bone-health gap during the estrogen-deficient menopausal state.
Recommendation. Suitable to combine for postmenopausal bone and symptom support. Take calcium with food in divided doses for best absorption.
