[Vitamin C and psychomotor reactivity]

The effect of vitamin C on the activity of the brain was studied. In groups of workers well provided for with vitamin C allowances a reduced number of industrial traumas was noted, which can be attributed to a greater concentration of attention and better reactivity. This could be achieved by administering daily doses of 100-150 mg of vitamin C. Workers engaged in night shifts were found to show improved psychotechnical test results with an ascorbinemia level of over 0.5 mg%. In a group of volunteers aged 16 to 18 years the results of psychomotor tests improved after a 14-day daily taking of 1000 mg of the vitamin C.
