Preventing hip fractures is more than just making sure you get enough calcium and vitamins D and K. According to researchers at the University of Oslo, Norway, optimal intakes of vitamins A, C, and E also are important. Blood was drawn for measurements of vitamins A, B6, B12, C, E, and folic acid as well as for bone turnover markers upon admission to the hospital for hip fractures in 116 patients. This data was compared to 73 controls with no history of hip fracture. Results showed that low blood levels of vitamins A, C, and E were independently linked with a risk for hip fracture. Low vitamin A increased risk by 26%, vitamin C by 6%, and vitamin E by 19%. The researchers speculate that these three vitamins are important in bone turnover mechanisms and are needed to prevent bone loss along with calcium and vitamins D and K.
