Older women with diabetes who take high doses of vitamin C may be doing more harm than good, finds School of Public Health professor David Jacobs.
Jacobs’ findings, published in the American Journal of Clinical Nutrition, reported on nearly 2,000 postmenopausal women with diabetes who were followed for 15 years. His research team found that those who took heavy doses of vitamin C supplements—300 milligrams a day or more—were roughly twice as likely to die of heart disease or stroke compared with women who took no vitamin C. The current recommended dietary intake for vitamin C is 75 milligrams per day for women.
