Personalized Vitamin D Therapy cuts Second Heart Attack Risk in Half, Study Finds
WASHINGTON D.C. - A new study reveals that personalized vitamin D supplementation significantly reduces teh risk of a second heart attack in patients with a prior history of cardiac events. The research, conducted in the United States, demonstrated a 50% decrease in the probability of experiencing another heart attack among participants receiving tailored vitamin D dosages.
The study, following 630 patients who had previously suffered a heart attack between April 2017 and march 2025, randomly divided participants into two groups: one receiving personalized vitamin D supplements and a control group receiving no vitamin D. Researchers closely monitored patients’ blood levels and adjusted vitamin D dosages accordingly to achieve individualized treatment.
While the study tracked instances of major cardiovascular events - including heart attack, stroke, and heart failure – a total of 107 participants experienced such events during the trial period. Though,no statistically critically important difference was observed between the two groups regarding the overall incidence of these major cardiac events.
The findings, initially reported by Science Daily, suggest a promising avenue for secondary prevention in cardiovascular health. Further research may explore the optimal vitamin D levels and personalized dosage strategies for maximizing benefits in this patient population.
