What is the key finding of the Intermountain Health study on vitamin D and heart disease?

The Intermountain Health study found that tailoring vitamin D supplementation based on individual blood levels can reduce the risk of recurrent heart attacks by over 50% compared to standard care.

How does the Intermountain Health study's approach differ from traditional vitamin D supplementation?

The study recommends a personalized, vigilant clinical protocol that adjusts vitamin D supplementation every three months, in contrast to the traditional "one-size-fits-all" fixed-dose model.

What is the global significance of the Intermountain Health study's findings on vitamin D and heart disease?

The widespread vitamin D deficiency and growing burden of heart disease globally emphasize the need for simple, cost-effective interventions like the personalized vitamin D supplementation approach highlighted in the study.

Tailored Vitamin D Doses Slash Heart Attack Risk by Over 50%

According to a study presented at the American Heart Association's Scientific Sessions 2025, researchers have discovered that personalizing vitamin D supplementation for patients diagnosed with heart disease can significantly reduce their risk of heart attacks. The study, conducted over a six-year period at Intermountain Medical Center in Utah, found that participants who underwent regular blood testing and tailored vitamin D dosing experienced a 52% reduction in recurrent heart attacks compared to those receiving standard care without vitamin D management.

The findings underscore the importance of addressing the widespread vitamin D insufficiency observed in this population, with over 85% of participants initially having suboptimal levels below 40 nanograms per millilitre (ng/mL) of blood. Researchers emphasize that this personalized approach to vitamin D supplementation, which aims to safely surpass the 40 ng/mL threshold, marks a departure from the traditional fixed-dose model and demands a rigorous monitoring protocol that adjusts the dosage every three months.
