Vitamin D Supplements Show Promise in Heart Health

The Australian D-Health Trial found that monthly high-dose vitamin D supplements did not significantly reduce major cardiovascular events in older adults over a period of up to 5 years. However, there were indications of potential benefits for certain components of the primary outcome, such as myocardial infarction and coronary revascularization. The study suggests further evaluation of the role of vitamin D supplementation, particularly in individuals taking cardiovascular medications. While previous trials have also shown no preventive effect of vitamin D supplementation on cardiovascular events, the researchers argue that conclusions about the impact of vitamin D on cardiovascular disease risk are premature.
