A systematic review of 17 prospective studies and randomised controlled trials suggests that vitamin D supplementation at moderate to high doses may reduce cardiovascular risk.
The results of one general-population study showed consistent reductions in CVD mortality among adults who received vitamin D supplements.
The results of eight other randomised trials showed a statistically non-significant 10% reduction in CVD risk in those taking vitamin D supplementation at doses of about 1000 IU/d, compared with those taking a placebo.
