Take a Vitamin D Blood Test to check Vitamin D levels. Levels of Vitamin D vary with exposure to sunlight, which is essential in Vitamin D production. Dietary intake of phosphorus is also critical in the production of Vitamin D. Also, when a person does not get enough calcium, levels of 1,25-dihydroxy D increase due to increased production of parathyroid hormone. Other factors that influence Vitamin D levels are the health of the thyroid, estrogens, calcitonin, human growth hormone, prolactin, insulin, and glucocorticoids. Vitamin D helps regulate calcium absorption from the diet, and is important for healthy bones.
Because of the complex control of calcium balance, it is often useful to measure parathyroid hormone in conjunction with vitamin D.
