Key Evidence #1
Public scholarly dataCitation signal: 131
meta-analysis

The primary efficacy outcomes were the incidence of dementia and scores on measures of overall cognitive function and the risk of bias of included studies using the Cochrane 'Risk of bias' assessment tool.

Key Evidence #2
Public scholarly dataCitation signal: 78
review

The findings of this systematic review suggest that supplementation of B Complex vitamins, especially folic acid, may have a positive effect on delaying and preventing the risk of cognitive decline.

Key Evidence #3
Public scholarly dataCitation signal: 65
observational

Overall results suggested that total B vitamins intake is associated with cognitive function in cognitively impaired AD and MCI elderly, and the association is stronger in AD patients.

Public scholarly dataCitation signal: 59
observational

A higher intake of dietary B vitamins, especially biotin, was associated with a lower prevalence of depression, anxiety, and stress symptoms, and the role of B vitamins requires further investigation in randomized controlled trials.
