Current recommendations for calcium intake call for 1,000 mg per day for women 
ages 19-50 and 1,200 mg per day for women over age 50 to ensure bone health. 
Given recent concerns that calcium supplements may raise risk for cardiovascular 
disease and kidney stones, women should aim to meet this recommendation 
primarily by eating a calcium-rich diet and taking calcium supplements only if 
needed to reach the RDA goal (often only approximately 500 mg per day in 
supplements is required).
