What is Vitamin D?



Vitamin D serves a key role in facilitating the absorption of calcium and phosphorus, which may help promote healthy bone function. New studies are also investigating its potential treatment in several other areas of health. The preliminary data has been promising. There are two primary forms found in vitamin D that are important to humans: D-2 (ergocalciferol) and D-3 (cholecalciferol). Although it is available in a few foods such as fatty fish, most dietary intake comes from products fortified with vitamin D, however, the greatest intake (80 to 90%) of it is obtained thru exposure to sunlight. A number of recent studies suggest higher than RDA amounts are needed in the diet to keep vitamin D levels in an adequate range.  Low levels of vitamin D have been found in many populations, especially those in more Northern climates who do not get enough exposure to the sun. Some other deficiencies are linked to falls and accidents in older populations. While adequate levels haven’t been clearly established, many authors feel the needed amounts are much higher than the RDA.  Therefore, supplementation with vitamin D to maintain optimal levels of this valuable compound is very important for active, exercising individuals.
