Objective: This study aimed to test whether citicoline can improve attention in healthy adult women aged 40–60.

Methods: 60 women were randomly assigned to take either 250 mg, 500 mg of citicoline, or a placebo every day for 28 days. They completed attention tests before and after supplementation.

Results/Conclusions: After 28 days, women who took citicoline made fewer errors in attention tests than those who took the placebo. Both the 250 mg and 500 mg groups showed improvements, with the higher dose showing slightly better results.
