Multivitamins improve cognitive function in impaired older adults

Older adults with mild cognitive impairment who use multivitamins have increased cognitive function, and lower serum homocysteine and depression levels according to a recent Korean placebo controlled trial. The data shows that at the end of the 12 week intervention the group that took the multivitamin supplement containing vitamin B6, B12, and folic acid had significantly increased cognitive function compared  to the control group (F = 3.624, p = .021).
