Folic acid and cognitive function: what is the final verdict?

摘要

In their systematic review on pyridoxine hydrochlo-ride (vitamin B_6), cyanocobalamin or hydroxyco-balamin (vitamin B_(12)), and folic acid supplementation on cognitive function, Balk et al concluded that the evidence does not yet provide adequate evidence of an effect of vitamin B_6 or B_(12) or folic acid supplementation, alone or in combination, on cognitive function testing in people with either normal or impaired cognitive function.
