People with low levels of vitamin D are more likely to die of any cause than those with higher levels of vitamin D, a study published June 23 in the Archives of Internal Medicine has shown.Previous studies have shown that low levels of vitamin D are related to heart disease, hypertension, and metabolic syndrome. The eight-year study conducted by Harald Dobnig, MD, of the Medical University of Graz, Austria, found that people with the lowest levels of vitamin D in their blood had the highest chances of dying.
Vitamin D levels may be important to maintaining general good health, the researchers suggest. Doctors generally recommend increasing vitamin D levels through diet and supplements instead of through increased exposure to the sun.
Vitamin D may affect how plaque builds up in the artery walls. Vitamin D may also protect against cancer and immune disorders. It is also essential for bone health, and may help prevent fractures and osteoporosis.
Vitamin D must be present in adequate amounts for calcium to be utilized in the body.
Studies have shown that women are consistently deficient in vitamin D, as are many of the elderly, who may not be getting enough sun exposure or who have inadequate diets.
Prescription and over-the-counter drugs that deplete vitamin D in your body include the use of mineral oil, antacids, prednisone, cholesterol-lowering drugs, dilantin, and many sedatives. Intestinal disorders, liver disease and gall bladder disease also rob the body of vitamin D.
The recommended daily dose of vitamin D is 200 international units (IU) for people up to age 50, 400 IU for people aged 51 to 70, and 600 IU for people over age 70. Some some medical professionals recommend levels as high as 2,000 IU a day. Levels above 600 IU per day should not be taken without first seeking your doctor's advice.
Vitamin D is inexpensive and readily available, and while cod liver oil, coldwater fish, egg yolks and butter are excellent sources of vitamin D, taking it in supplemental form is still the best and most convenient way to insure you're getting enough of this crucial vitamin. Only the most persistent sunbathers are getting enough vitamin D from exposure to the sun.
