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.

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.

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.

I am 62 years old and just had my second bone-density test. I was told I have osteopenia and should take Boniva. I have been lactose-intolerant, so I avoid dairy products. I have tried calcium, but it makes me constipated. I took Actonel but developed leg cramps. I took one Boniva tablet the nurse gave me as a sample, but I now have unbearable indigestion. Is there anything natural I can take? Osteopenia is a controversial condition. The concept of pre-osteoporosis was created somewhat arbitrarily in 1992 for research purposes rather than to guide treatment.

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.

Vitamin D levels in most Americans are adequate, with only 8% of the population at risk for health problems because of low vitamin D, according to a government report. Vitamin D is one confusing nutrient. Numerous studies in recent years have linked deficiency to a range of health problems and disease risk, including cancer, autoimmune diseases and diabetes. The nutrient also has a well-defined role in bone health. Some doctors and researchers have called for an increase in the recommended dietary intake of vitamin D. But in a report released late last year, the Institute of Medicine declined to raise the values saying: "The IOM finds that the evidence supports a role for vitamin D and calcium in bone health but not in other health conditions.
