The calcium supplements widely prescribed for bone health in women did not appear to be associated with increased cardiovascular risk, researchers found.
An analysis looking at outcomes for women who took more than 1,000 mg of calcium each day -- the dose that has been used in many of the trials included in the meta-analyses -- no significant risks were identified:
Coronary heart disease, RR 0.75 (95% CI 0.65 to 0.88)
Nonfatal MI, RR 0.74 (95% CI 0.62 to 0.88)
Fatal MI RR 0.81 (95% CI 0.60 to 1.09)
Stroke, RR 1.01 (95% CI 0.85 to 1.21)
Nor were any associations seen for stroke subtypes.
