The body makes this itself, from the substrate Choline. Our diets tend to be low in choline in the US. It is now added in some children's vitamins for this reason. (to help with CNS development and learning). I am unsure as to how useful it would be for you, as PS is usually used for CNS issues.
One of the best food sources of choline is egg yolks. Much less expensive that way. Phosphatidyl serine is quite expensive.
PS is rather benign and not harmful, if you want to spring for it and try it however.
