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.

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 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.

People who take vitamin D tablets appear to be almost half as likely to get deadly pancreatic cancer as people who do not, researchers have found. Now they're checking to see whether getting the vitamin from food or sunlight also cuts the risk. The study suggests one easy way to reduce the risk of pancreatic cancer, the fourth-leading cause of death from cancer in the United States.

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.

Vitamin D deficiencies can cause severe muscle weakness that leaves victims unable to walk, according to University of Buffalo endocrinologists. Although the problem can easily be treated with vitamin D supplements, the disorder is often diagnosed as a more serious disease, says Dr. Paresh Dandona. Vitamin D is produced by the liver in the presence of sufficient calcium and sunlight, and deficiencies are generally caused by limited exposure to the sun and insufficient intake of dairy products.

Medical researchers are homing in on a wonder drug that may significantly reduce the risk of heart disease, cancer, diabetes and many other diseases -- sunshine. A study released today found that men who are deficient in the so-called sunshine vitamin -- vitamin D -- have more than double the normal risk of suffering a heart attack. Just last week, another study found that low levels of vitamin D increased the risk of diabetes, and a study last month linked deficiencies to an increased risk of dying from breast cancer.

More than half of American women over the age of 60 take vitamin D and calcium supplements, but the U.S. Preventive Services Task Force said this week that they're probably wasting their money. In a new recommendations from the federal government's expert panel on preventive medicine, the task force says that most postmenopausal women should not take vitamin D and calcium to reduce their risk of bone fractures. The dosages assessed were 400 international units (IUs) of vitamin D3 and 1,000 milligrams of calcium per day. The conclusions are based on an analysis of six randomized trials designed to study the health effects of vitamin D and calcium supplements.

If you're trying to ward off the sniffles, you can take vitamin D supplements out of your shopping cart: A new study reports that dosing with the vitamin does nothing to prevent colds or other forms of upper respiratory tract infections (URTI). The effect of vitamin D on the immune system has been debated for a long time. Controlled laboratory research has shown that vitamin D has several beneficial effects on the immune system, and some studies conducted in the past have suggested that people with low levels of the vitamin are at higher risk for URTIs.

I was deeply saddened with the Institute of Medicine report that we are a healthy nation in regard to our calcium and vitamin D intakes ["Sweeping Away the Hype About Vitamin D," Dec. 6]. As a physician keenly interested in my patients' nutrition status and needs, I find the report flawed. By arbitrarily setting the lower limit of normal vitamin D blood level at 20 nanograms per milliliter, they are missing the borderline deficiency between 20 and 40 ng/ml. I recommend 2,000 international units of vitamin D per day to my adult patients.
