“Effects of a multi-vitamin/mineral supplement on cognitive function and fatigue during extended multi-tasking,”
Haskell CF, Robertson B, et al, Hum Psychopharmacol, 2010 Aug; 25(6): 448-61.
In a randomized, double-blind, placebo-controlled, parallel group study involving 216 females between the ages of 25 and 50 years of age, supplementation with a multivitamin/multimineral (Supradyn®) for a period of 9 weeks was found to have beneficial effects. Prior to intervention, and then again 9 weeks after the intervention commenced, subjects completed a four-module version of the Multi-Tasking Framework, and cognitive function and the modulation of task-related mood/fatigue were assessed during 2 discrete 20 minute assessment periods. A significant attenuation of the adverse effects of extended task completion on mood/fatigue was found among subjects in the multivitamin/multimineral group. Moreover, improved speed and accuracy in multi-task performance was also found among subjects taking the supplements. A subgroup (n=102) of subjects were found to have significant reductions in levels of homocysteine following supplementation. The authors conclude, “These findings suggest that healthy members of the general population may benefit from augmented levels of vitamins/minerals via direct dietary supplementation.”
