Vitamin D (calciferol) has always been touted as good for the bones. However, recent research posits this vitamin is conducive to a healthier heart. There is a significant correlation between calcium and vitamin D regarding cardiac muscle function, metabolism, and overall cardiovascular health.
Insufficient vitamin D levels limit the body's ability to absorb more than 10% to 15% of dietary calcium. The body needs sufficient vitamin D levels to improve the intestinal absorption of calcium to 30% to 40%. Calcium performs vital functions such as:
Calcium regulates blood pressure levels by letting the blood vessels tighten and relax when needed. By working together, calcium and vitamin D help promote balanced blood pressure, reducing the risk of hypertension or high blood pressure.
This is an extension of calcium's ability to regulate blood pressure, which enables a healthy cardiovascular system, supporting the heart's electrical stability. It helps the prevention of cardiovascular diseases such as heart disease and stroke.
A proper calcium balance regulates the heart's rhythm, reducing the risk of arrhythmias or irregular heartbeats.
The flip side is that overdoing calcium levels could increase calcifications (hardened calcium deposits) in the blood vessels. These calcifications cause your blood vessels not to work well, as blood can’t flow as easily. But this needs to be confirmed by large randomized trials before we can draw any definite conclusions about the connection between vitamin D and heart attack risk.
It is advisable to consult with your doctor for personalized guidance on maintaining optimal Vitamin D and calcium levels and promoting a healthy heart.
