Research Raises Questions About Vitamin D’s Heart Benefits
Supplementing with vitamin D may not improve cardiovascular health.
Vitamin D’s importance to bone and muscle health is indisputable, though it’s less clear how that key nutrient affects heart health. Several studies in recent years have suggested that vitamin D plays a key role in keeping your blood vessels healthy and your heart muscle strong. The consensus is that individuals with low vitamin D levels tend to be at higher risk of cardiovascular events such as heart attack. But not all research supports the idea that vitamin D supplementation is the answer to lowering your risks.
