Vitamin D

A synthetic form of Vitamin D appears to significantly reduce the risk of fractures in older women with brittle bones, according to a study in the New England Journal of Medicine. Dr. Murray W. Tilyard and his colleagues at the University of Otago in New Zealand said their work suggests that the drug, called calcitriol, "is an important therapeutic option" for women with thinning bones after menopause. However, this approach is controversial.
Even slightly elevated blood pressure--in the range physicians call high normal--significantly increases the risk of heart disease, a new study has found. Researchers have long known that greater elevations are a significant risk factor for heart disease, but the new study indicates that anything above normal represents some risk.

Adults with a vitamin D deficiency are more likely to die over a certain period than those with high levels, another indication of the nutrient's vital role in guarding against ailments from heart disease to cancer, U.S. researchers said Monday. Several recent studies have shown that vitamin D may protect against heart disease, cancers of the colon and breast, diabetes and tuberculosis. Those with the lowest levels of the "sunshine vitamin" had a 26% increased risk of death over eight years compared with those who had the highest levels, the researchers reported in the Archives of Internal Medicine.

I had severe leg pain for months. My doctor did blood work and found that my vitamin D level was 8. She prescribed me 50,000 IUs per week for 12 weeks, and now my leg pain is almost nonexistent. This is a common prescription dose for correcting a severe vitamin D deficiency. Many people have less than optimal levels of this vitamin. Lower than 20 nanograms per milliliter indicates deficiency. Some experts believe that optimal levels should be at least 30.
As spring weather begins to warm the outdoors, many of us around the country are venturing outside to enjoy the bright sunshine. At the same time, exposure to ultraviolet radiation is replenishing our bodies' supplies of Vitamin D. Today we take sunshine for granted. But after the industrialization of Northern Europe, crowded housing, narrow streets and smoke-filled skies shut out sunlight and produced an epidemic of the D-deficiency disease, rickets, which lasted for many years.

Every once in a while, some unsung nutrient gets rediscovered and, in the course of a few short years, is rendered virtually magical in the eyes of health professionals and consumers. Foods containing the nutrient come into vogue and supplement use soars. Then, seemingly overnight, the spell is broken. Last week, it was vitamin D's turn to fall from grace. The comedown came courtesy of an expert panel convened by the Institute of Medicine, which advises the government on health issues.

The American Academy of Pediatrics has doubled its recommendation for children's daily dose of vitamin D in the hopes of preventing rickets and reaping other health benefits, the group said Monday. "We are doubling the recommended amount of vitamin D children need each day because evidence has shown this could have lifelong health benefits," said Dr. Frank Greer of the American Academy of Pediatrics, which released the new recommendations at a meeting in Boston.

Vitamin D may be helpful in protecting highly active pre-teen and teen girls, such as those who play sports, from stress fractures, researchers reported Monday. The study was surprising because calcium has long been considered the nutrient most vital to bone health in children. But, in developing children, vitamin D intake may matter more. Researchers analyzed data from 6,721 girls ages 9 to 15 at the start of the study. The girls' intake of calcium, vitamin D and dairy products was recorded along with stress fractures, which are common sports-related injuries.

  We mostly get our vitamin D by exposure to the sun, and these days, who just goes out in the sun? So there's been a lot of attention given to - and confusion over - vitamin D supplements, something many doctors recommend. Now there's a new study a possible vitamin D benefit: In a group of women older than 65 who had gained weight over 4½ years, those whose levels of the vitamin were low had gained a little more weight, researchers found in a study published Monday.

Vitamin D has emerged as something of a wonder supplement, according to the claims of dozens of studies published in the past few years. Researchers have suggested that adequate levels of the nutrient not only strengthen bones, but reduce the risk of cancer, heart disease and other conditions. Several studies also suggest Americans are not getting enough vitamin D, which is synthesized in the skin from sun exposure and found in certain foods, such as fortified milk and cereal, some types of fish and legumes.
