Does phosphatidylserine help depression?

One study found that regular supplementation of phosphatidylserine helps reduce symptoms of depression in nearly half of all subjects. When combined with omega-3 fatty acids, phosphatidylserine may help reduce symptoms of a ttention deficit hyperactivity disorder (ADHD). Subsequently, does phosphatidylcholine help with depression? Case reports, open trials and one small double-blind study suggest that supplementation with phosphatidylcholine 15 g to 30 g/day reduces the severity of both mania and depressed mood in bipolar patients, and that symptoms recur when phosphatidylcholine is discontinued.

And another question, what are the side effects of phosphatidylcholine?

When phosphatidylcholine is taken by mouth, it can sometimes cause excessive sweating, stomach upset, and diarrhea. Phosphatidylcholine injections can cause irritation, swelling, redness, itching, burning, bruising, and pain at the injection site. These side effects usually go away over a period of several days.
