First, unlike the daily 80 mg aspirin regime recommended for those at risk of developing heart disease, patients in this study took 600 mg a day (in two 300 mg pills).
But a new Kyowa-funded study of 60 healthy women found a monthlong regime of daily doses of citicoline resulted in improved attention and fewer errors on a cognitive test compared with placebo, says co-author Deborah Yurgelun-Todd, a scientist at the Brain Institute at University of Utah in Salt Lake City, who is a paid consultant to Kyowa.
The regime the team has devised is a combination of a daily pill made of desogestrel (an artificial form of progesterone) and a slow-release testosterone pellet that is placed under the user's skin.
