Citicoline
Citicoline is an over the counter supplement that may have neuroprotective properties and may have antidepressant effects. Citicoline or placebo (identical in appearance) add-on therapy was given beginning at one tablet (500mg/day) with an increase to two tablets (1000 mg/day) at week 2, three tablets (1500 mg/day) at week 4 and four tablets (2000 mg/day) at week 6. Doses were decreased, if needed, due to side effects.
