Impact of Vitamin D Supplementation on Cognition in Adults With Mild to Moderate Vitamin D Deficiency: Outcomes From the VitaMIND Randomized Controlled Trial

Preserved cognitive health with ageing is a public health imperative. Vitamin D deficiency is associated with poor cognition, but it is unclear whether supplementation would provide benefit, particularly in individuals with mild/moderate deficiencies which do not have other clinical risks. The objective of this study was to establish the impact of daily vitamin D supplementation on cognition in older adults with mild to moderate vitamin D deficiency.
