A recent study has revealed encouraging findings concerning the potential advantages of vitamin D supplements in reducing the likelihood of major cardiovascular events, specifically among individuals aged 60 and above.

Although the findings are not definitive, the Vitamin D supplementation and major cardiovascular events: D-Health randomised controlled trial shed new light on the role of vitamin D in cardiovascular health.

Professor Rachel Neale, an epidemiologist and the head of QIMR Berghofer’s Cancer Aetiology & Prevention Group, served as the lead author of the study. She noted that the D-Health Trial is the second-largest trial of its kind to date,

“Our trial found vitamin D supplementation may reduce the risk of major cardiovascular events, and the protective effect could be more marked in those taking statins and other heart disease drugs. It does suggest that further research into this is needed,” Neale said.

The D-Health Trial spanned from 2014 to 2020 and involved more than 21,000 Australians aged between 60 and 84. Participants were randomly assigned to receive either vitamin D supplements or a placebo on a monthly basis for up to five years. The trial aimed to investigate the preventive role of vitamin D in various diseases.

During the trial, the group receiving vitamin D supplements exhibited a slightly lower rate of major cardiovascular events (6 per cent) compared to the placebo group (6.6 per cent).

The vitamin D group also experienced a 9 per cent lower rate of major cardiovascular events overall, with a 19 per cent lower rate of heart attacks compared to the placebo group.

While the results are promising, it’s important to note that the researchers caution against drawing definitive conclusions. Despite the potential benefits, the team emphasises that all supplements come with costs.

While there is some evidence supporting the use of vitamin D for reducing cardiovascular risk, consumers should make informed decisions and consider discussing supplementation with their doctors, particularly individuals over 60 with existing medical conditions.
