• TARGET-D Study: Presented at the American College of Cardiology conference, it showed that patients maintaining vitamin D levels between 40-80 ng/mL (100-200 nmol/L) had half the risk of heart attack, especially post-heart attack patients.
• Expert Opinions: Cardiologist Dr. B. Keith Ellis notes long-observed links between low vitamin D and cardiovascular risks; Prof. Markus Herrmann praises it as the first study specifying target blood levels for clearer conclusions.
• Vitamin D Roles: Supports bone metabolism with calcium, immune system, brain/muscle cells; potential anti-inflammatory effects, blood pressure/sugar regulation may protect the heart.
• Causation Debate: Low vitamin D might be a confounding factor reflecting outdoor activity and healthier lifestyles rather than direct cause.
• Sources and Deficiency: Found in fatty fish (salmon, sardines), fortified foods; body produces via sunlight; up to 1 billion people worldwide deficient, worse in northern countries during winter.
• Prior Trials: D-Health and VITAL trials showed no clear benefits; D-Health had borderline results for reducing heart attack risk.
