Biochemists have elucidated the structure of an enzyme that supplies carotenoid, investigators report. The lack of vitamin A in food is a major cause of health problems worldwide and can lead to blindness and even death. This is especially a problem in threshold or third-world countries, where children are likely to suffer from a lack of vitamin A or its precursor beta-carotene due to malnourishment.img src=http://feeds.feedburner.com/~r/sciencedaily/health_medicine/vitamins/~4/3y1CPxqUxvQ heigh...
It lurks in hospitals and nursing homes, preying upon patients already weak from disease or advanced age. It kills nearly 30,000 Americans a year, and sickens half a million more. But new research shows that Clostridium difficile bacteria cant do all this without enough of a humble nutrient: calcium. And that new knowledge may lead to better treatment for the most vulnerable patients.img src=http://feeds.feedburner.com/~r/sciencedaily/health_medicine/vitamins/~4/u5ox1yMMPP4 height=1 width=1 alt=...

Even in advanced medical settings, sepsis is still very dangerous and accounts for over 400,000 deaths annually in the US alone. While new drugs are in development, a group of researchers has determined that a combination of intravenous vitamin C, corticosteroids (a steroid), and thiamine (vitamin B) may be effective in preventing progressive organ dysfunction and reducing the number of deaths from severe sepsis and septic shock.img src=http://feeds.feedburner.com/~r/sciencedaily/health_medicine...
From 1999 through 2014 the number of US adults taking daily vitamin D supplements above the recommended levels increased, and 3 percent of the population exceeded the daily upper limit considered to possibly pose a risk of adverse effects, according to a study.img src=http://feeds.feedburner.com/~r/sciencedaily/health_medicine/vitamins/~4/hF3v6-8h8PI height=1 width=1 alt=/...
