In a small pilot study, eight people complaining of memory problems took 300 mg of phosphatidylserine (PS) plus 37.5 mg of omega-3s (EPA and DHA) per day. To enter the study, participants could not be taking any medications or other supplements, did not have allergy to soy or fish, and were able to complete a basic cognitive test.

At the start of the study and after six weeks, researchers tested power and length of attention, and quality and speed of working memory—the type people need for holding and recalling information to solve problems, even through distractions or interference.

After taking PS and omega-3s for six weeks, participants were able to store, hold, and recall information better overall, and were able to recall 42 percent more words on a list after a time delay.
