What is Vitamin D and why is it so important?

Headaches and Dizziness

These symptoms are common with high blood pressure, which is also a common complaint from those with vitamin D deficiency. High blood pressure, however, is often called a “silent killer” because, although it is a risk factor for heart attacks and strokes, some people have no warning signs at all.  However, if you are having headaches and dizziness and you suspect that your blood pressure may be high, you should definitely talk to your doctor.
