The present study assessed the potential cognitive-enhancing effects of citicoline, a dietary supplement, in healthy adult women. Specifically, it was hypothesized that citicoline supplementation would be associated with improved attention compared to placebo.

Results: All 60 participants were included in the analyses, which included an ANOVA with Tukey’s post-hoc tests and t-tests. After 28 days of supplementation, individuals in the 250 mg group made fewer omission (p = 0.04) and commission (p = 0.03) errors compared to those in the placebo group. Individuals in the 500 mg group made significantly fewer commission errors compared to those in the placebo group (p = 0.03) and trended toward making fewer omission errors (p = 0.07).
