Very low evidenceVitamin D + Vitamin Cfor Improved Cognitive Function· 3 studies
Of the 3 studies examining the combination of vitamin D and vitamin C for cognitive function, 1 reported a beneficial effect while 2 found neutral effects. The single beneficial finding came from a systematic review that did not isolate the combination, and the other two reviews/meta-analyses found no significant effect. Compared to vitamin D alone (which showed neutral effects across 3 solo studies), the combination evidence is similarly inconclusive. No consistent dose, form, or duration data were reported across studies.
