Recently, there has been a lot of medical attention vis-a-vis calcium, and to a lesser extent, Vitamin D.  Many patients are confused, hence this post.  Make no mistake – calcium and vitamin D are crucial for healthy bone.  The current recommendation is for 1000mg of elemental Calcium for women up to age 50 and 1200 mg for women above age 50.  I have been telling my patients for years that you are best off getting your calcium from diet.  Some evidence suggest that calcium supplements may be a factor slightly raising risk for heart disease and kidney stones.  In addition, this is from calcium supplements not dietary sources.  If you are consistently below 1000-1200mg per day depending on your age some supplementation would be appropriate.
