ABSTRACT
Objective: To observe the effects of nutrients-compound supplementation (NS) on cognitive function. Method: Forty six young male volunteers were randomly divided into 2 groups, NS and control (CT). NS group was supplemented with nutrients-compound while CT group received placebo for 60 d.The cognitive function of all volunteers were examined by 《CHANG-AN Handbook of Group Intelligence Test》 and Wechsler Memory Scale(WMS). Their vitamin status was assessed by 4-h load test at the end of experiment. Results : The vitamin nutriture of NS group was significantly better than that of CT. Many achievements of cognitive test of NS group were obviously increased compared to that before supplementation or that of CT. The visual responding time was shortened in 3 tests and the error number was decreased in 1 test of NS group, while no significant change was observed in CT group. Conclusion: Supplementation with the nutrients-compound is beneficial to improvement of cognitive function such as learning, memory and understanding.
