Vit C works as a antioxidant preventing damages caused by oxygen residuals attacking brain cells....Vit B (thiamin, niacin, pyridoxin before all) help to "extract energy" from food, fight stress and fatigue and manifacture neurotransmitters...B empowers nervous system and works partly as antioxidant (thiamin B1) and cyanocobalamin (B12) was tested on lab animals showing indication of improved learning
...one cannot expect miracles...vitamins R noticable when your body lacks them...also hyperdose of them is not the way to go...Taking C or B I don't expect to crunch numbers in half time limits then before..boosting cognitive abbilities (U can imagine lots of things this can cover) through chemistry seems problematic theese days..maybe some other day......:-))
