Here is a quick abstract of some info particularly interesting to me in regards to the Phosphatidylserine (PS). I originally was researching its benefits regarding cortisol reduction however there is some debate in this regard with bovine vs soy derived PS (Bovine PS is no longer available in the U.S.).

I noticed there seem to be quite a few other benefits to PS and in particular the recovery from muscle soreness or the prevention of muscle soreness.
Anyway here is the link to the full article (great read btw):
Phospholipids and sports performance
Finally, does anyone wanna help me bug NP to get this stuff in bulk? I'd like to try it but 800mg's/day (based off the studies performed) would likely be somewhat expensive just purchasing the NOW brand they have available.

Phospholipids and sports performance.

ABSTRACT: Phospholipids are essential components of all biological membranes. Phosphatidylcholine (PC) and Phosphatidylserine (PS) are Phosphatidyl-phospholipids that are required for normal cellular structure and function. The participation in physical activity often challenges a variety of physiological systems; consequently, the ability to maintain normal cellular function during activity can determine sporting performance. The participation in prolonged intense exercise has been shown to reduce circulatory choline concentrations in some individuals. As choline is a pre-cursor to the neurotransmitter Acetylcholine, this finding has encouraged researchers to investigate the hypothesis that supplementation with PC (or choline salts) could enhance sporting performance. Although the available data that evaluates the effects of PC supplementation on performance are equivocal, acute oral supplementation with PC (~0.2 g PC per kg body mass) has been demonstrated to improve performance in a variety of sporting activities where exercise has depleted circulatory choline concentrations. Short term oral supplementation with soy-derived PS (S-PS) has been reported to attenuate circulating cortisol concentrations, improve perceived well-being, and reduce perceived muscle soreness after exercise. More recently, short term oral supplementation (750 mg per day of S-PS for 10 days) has been demonstrated to improve exercise capacity during high intensity cycling and tended to increase performance during intermittent running. Although more research is warranted to determine minimum dietary Phospholipid requirements for optimal sporting performance, these findings suggest that some participants might benefit from dietary interventions that increase the intakes of PC and PS.
