Researchers find link between specific vitamin D levels and heart disease risk

Vitamin D deficiency is linked to serious health risks such as coronary artery disease, heart attacks, and strokes with a new study showing what level of deficiency puts someone at risk. Researchers at the Intermountain Medical Center Heart Institute in Salt Lake City, Utah, US, have found that patients are fine from a heart standpoint, and may need no further treatment, if their vitamin D level is anywhere above 15 nanograms per millilitre which is the equivalent of 37.5 nanomoles per litre.
