Life Extension Update. June 2013
Tuesday, June 11, 2013. In an article published online on May 29, 2013 in the journal Ageing Research Reviews, researchers from The Netherlands report an association between reduced serum levels or intake of vitamin D and a greater risk of cognitive decline.
For their review, M. H. Emmelot-Vonk and colleagues at University Medical Center Utrecht selected 25 cross-sectional studies (which examine a specific population at one point in time) and six prospective studies (which follow a group of subjects over a given period of time) that examined the association between vitamin D status and cognition. The cross-sectional studies included a total of 48,680 men and women, and the prospective studies included 10,896 subjects who were followed for 4 to 7 years.
