Vitamin D

Vitamin D is essential for good bone health and possibly other important functions, including protection against autoimmune diseases and cancers. This test measures the total reserves of vitamin D3 (produced by exposure to sunlight and found in animal-based supplements) and vitamin D2 (plant-based, found in most supplements). Low sun exposure, certain medications, malnutrition and intestinal malabsorption are the most common causes of vitamin D deficiency.
