A randomised, controlled comparison of different calcium and vitamin D supplementation regimens in elderly women after hip fracture: The Nottingham Neck of Femur (NONOF) Study

Abstract

Vitamin D supplementation, either orally or with injected vitamin D, suppresses parathyroid hormone, increases bone mineral density and reduces falls. Effects may be more marked with calcium co-supplementation. The 300,000 units of injected vitamin D may not last a whole year.
