Previous work has identified the positive effects of the acute administration of a multivitamin-guaraná preparation during an effortful executive/working memory task. Here, we aimed to differentiate the effects of multivitamins with and without guaraná and to examine the neural substrates of such effects using functional magnetic resonance imaging (fMRI). Following a double-blind, placebo-contr...

After nearly a lifetime of consuming a bizarre diet limited to French fries, pretzels, crackers, and carbonated sodas, he had a relatively sudden onset of night blindness and bilateral visual loss. The night blindness resolved after taking daily oral vitamin A supplements. Visual acuity gradu...
