In recent years, neurodegenerative diseases are a leading cause of morbidity and disability worldwide, with Parkinson's disease (PD) being the most prevalent. Although diet and vitamin status play a crucial role in PD, the results of vitamin D supplementation are scarce and contradictory. Therefore, the present systematic work reviewed the available randomized controlled trials (RCTs) regarding the role of vitamin D supplementation in patients with PD in the Pubmed, Scopus and Cochrane databases and in grey literature. Four RCTs including 321 patients with PD were identified. Various doses of vitamin D were administered (1,000- 10,000 IU/d) and different exposure outcomes were assessed. One study reported beneficial effects of vitamin D on the Hoehn and Yahr scale (HY) and two studies reported null effects on the Unified Parkinson's Disease Rating Scale (UPDRS). Regarding functional tests, heterogeneous results in the timed-up and go (TUG) test were observed in two studies. One study conducted minute walking tests at 6 and 10 minutes and found an improvement only in the 6MWT. In conclusion, a very small number of RCTs have assessed the effects of vitamin D supplementation on PD. Some isolated beneficial effects of vitamin D were reported on functional scales and tests but more studies are needed to draw safe conclusions regarding its supplementation in PD.

- Associated with PD are: Meta-analyses (
12 ), Cognition ( 24 studies), Multiple Sclerosis ( 18 studies), VIRUS ( 4 studies), Omega-3 ( 3 studies), Vitamin D Receptor ( 11 studies) - Note by the Founder of VitaminDWiki: I have twice recommended lots of Vitamin D to treat PD. Both got much better, but one had his doctor him cut back to just 2,000 IU. All of his recovery got reversed. With lots of vitamin D he could sing and bike, but now he can barely talk or walk
