Neurocognitive effects of multivitamin supplementation on the steady state visually evoked potential (SSVEP) measure of brain activity in elderly women

► The SSVEP was examined before and after 16 weeks multivitamin or placebo treatment. ► The multivitamin increased SSVEP latency during spatial working memory performance. ► Increased latency was interpreted as an increase in inhibitory neural processes. ► Multivitamin supplementation may influence cognition by enhancing neural efficiency.
