Research output: Contribution to journalShort survey

Abstract

• Vitamin D has classic calcemic actions that are critical to a healthy skeleton, as well as noncalcemic actions that support vital bodily functions (cardiovascular, immune). • The definition of vitamin D adequacy remains controversial; however, 25-(OH) D levels > 30 ng/mL are recommended to support classic calcemic actions, whereas many investigators cite 50-80 ng/ mL as optimal for disease prevention via nonclassical pathways (cardiovascular, immune). • There appears to be a pandemic of vitamin D deficiency, more notable in regions with poor UVB exposure. Other risk factors include being elderly or dark skinned, wearing excessive sunblock, having a diet poor in vitamin D-containing foods, taking anticonvulsant medications, and being bed-bound or in the hospital setting. Oily fish and shiitake mushrooms are overlooked food sources that are rich in vitamin D.
