Do calcium supplements prevent postmenopausal osteoporotic fractures?

Abstract

Calcium supplementation (1000-1200 mg daily) decreases menopause-related bone loss and reduces the rate of vertebral and non- vertebral fractures. Calcium is more efficacious in conjunction with vitamin D (700-800 IU daily), particularly in elderly patients, who have a high rate of vitamin D deficiency (strength of recommendation: A, based on randomized controlled trials).
