A new study finds that Vitamin D with calcium supplementation significantly reduces fracture risk, but Vitamin D supplementation alone does not offer much protection. Researchers from Queen’s Medical Center is Nottingham, England evaluated seven randomized, controlled trials with using Vitamin D with calcium or using Vitamin D alone to prevent fracture risk. The studies included over 68,000 participants between the ages of 47 and 107 years (average age of 70 years) with 14% mean and 86% women. The results of the analysis showed that 10 µg of vitamin D given with calcium reduced fracture risk in men and women of all ages. Vitamin D supplementation in daily doses of 10 µg or 20 µg had no significant effect on fracture risk. The authors concluded that Vitamin D and calcium supplementation significantly reduce the risk of fractures, but Vitamin D supplementation alone does not reduce fracture risk.
