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.
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.

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.
[Abstract]: Alzheimer's disease (AD) is a brain disorder displaying a prevalence and impact in constant expansion. This expansive and epidemic behavior is concerning medical and public opinion while focusing efforts on its prevention and treatment. One importa
This study shows that GPB/B1-B12 combination is as effective as PGB in patients with moderate to severe intensity PDN, and pain intensity reduction is achieved with 50% of the minimum required gabapentin dose alone in classic NDD trials.
