A recent study reveals that this supplement may have heart-protective benefits, particularly for older persons who are already using cardiac medications.
According to a sizable new study published this week in The BMJ, high-dose vitamin D supplements given once a month may reduce the risk of heart attack or other serious cardiac events in persons 60 and older.
Researchers found that vitamin D supplementation may reduce the risk of heart attack and the requirement for coronary revascularization (procedures that restore blood flow to parts of your heart that are not getting enough blood), even though the level of risk reduction was modest.
Research on the advantages of vitamin D for the heart has so far been inconsistent. The authors of the study noted that several earlier studies had shown that taking supplements did not prevent heart problems.
A 2019 JAMA Cardiology review included 21 clinical trials and more than 83,000 individuals arrived at the conclusion that vitamin D supplements do not lower the chance of experiencing or passing away from a stroke or heart attack.
According to Rachel Neale, PhD, deputy coordinator of the population health department at the QIMR Berghofer Medical Research Institute in Queensland, Australia, and her study coauthors, “These findings suggest that conclusions that vitamin D supplementation does not alter the risk of cardiovascular disease are premature.”
Further research on the benefits of vitamin D supplementation, particularly in those taking medications for the prevention or treatment of cardiovascular disease, may be prompted by these findings, the authors concluded.
More than 21,000 individuals between the ages of 60 and 84 who were split into two groups and given either a placebo or a monthly vitamin D tablet containing 60,000 IU (international units) each participated in the analysis.
