The latest HERU Blog post highlights a recent study on the effectiveness of vitamin K2 on preventing falls in older people who are at risk of falling. Professor Paul McNamee of HERU was involved in the study which was funded by the Chief Scientist Office (CSO). The study found no strong evidence that vitamin K2 would prevent falls. There is scope for further research though.
