With the addition of the 2 recently published randomized trials of folic acid described by Naina et al, the evidence remains inconclusive, although folic acid supplementation may benefit specific populations. Even with these trials, as we reported, “firm conclusions are not possible” and the trials “do not provide adequate evidence for a beneficial effect of supplementation on cognitive function testing in people with either normal or impaired cognitive function.”1(p29)
