A high intake of vitamin C may help reduce bone loss in elderly men, according to a new study. However, the same is not true for women of the same age group.

Lead researchers Katherine L. Tucker, a senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University and her team evaluated the bone density of 213 men and 393 women, average age 75 at the start, over a four-year period to see what association their vitamin C intake had with their bones

Intravenously delivered vitamin C helps lowering high blood pressure by calming an overactive central nervous system, new Italian research suggests.

Lead author Dr. Rosa Maria Bruno from the University of Pisa treated 12 patients with high doses of vitamin C given intravenously. None of the patients had received any kind of prior treatment for their condition. Over a five-minute period, all the patients were intravenously administered three grams of vitamin C
