Fracture risk reduced by high dietary calcium

Analysis of current evidence suggests individuals with adequate dietary intake of calcium (around 1200mg daily from dairy products and green leafy vegetables) should avoid supplementation although it could be considered for those with deficiency who are at increased risk, according to a review in the New England Journal of Medicine.

Fracture risk reduction with supplements is modest (10% in one meta-analysis) and several studies have suggested adverse cardiovascular effects, the reviewer said.
