"Phosphatidylserine has been demonstrated to speed up recovery, prevent muscle soreness, improve well-being, and might possess ergogenic properties in athletes involved in cycling, weight training and endurance running. Soy-PS, in a dose dependent manner (400 mg), has been reported to be an effective supplement for combating exercise-induced stress by blunting the exercise-induced increase in cortisol levels"
I was taking a good amount of that and flared early 2010. I think I need all the coritisol I can produce since prednisone is simply synthetic coritisol.
I have never taken that one again. Phosphatidylcholine is good.
