This Chinese study aimed to determine whether vitamin D levels correlate with the conditions of bones and various symptoms in patients with Parkinson’s disease. The study included 182 patients with Parkinson’s disease and 185 healthy people. The scientists detected significantly lower vitamin D levels in patients with Parkinson’s disease than in healthy participants. Furthermore, Parkinson’s disease patients with lower vitamin D levels had a significantly higher frequency of falls and insomnia. They also suffered more often from depression and anxiety. These results indicate that vitamin D supplementation is a helpful therapy for several symptoms of Parkinson’s disease. More details can be found in the study.
