Formatted Abstract/Summary
Introduction: Deficits in cognitive functioning, especially episodic memory, are commonly reported as people age. It has previously been suggested that cognitive function might be improved with nutritional intervention, and that this may be partly due to a resultant reduction in homocysteine levels. Multivitamins are commonly used supplements in the general population but their effects on cognition are not clear. This study examined the effects of multivitamin supplementation on cognition in adults at risk of cognitive decline.

Methods: Participants were forty males aged 50-69 years. The study was a double blind, placebo controlled design. Participants were randomly allocated to receive either 1 multivitamin or 1 placebo tablet per day. Computerised cognitive tasks and blood homocysteine measures were performed at baseline and after approximately 8 weeks supplementation.

Results: Multivitamin supplementation significantly improved performance on an episodic memory task (p<.01), with no change in the placebo group. Effects of supplementation on other cognitive tasks are discussed. Homocysteine levels were reduced significantly after supplementation with the multivitamin (p<.001) but not with placebo.

Discussion: Eight weeks supplementation with a multivitamin was able to improve performance on an episodic memory task. Multivitamin supplementation may be useful in enhancing cognition in people at risk of cognitive decline.
