    CRhodiola Rosea

    Minor

    Increases in processing accuracy are likely secondary to reductions in fatigue

    CPhosphatidylserine

    Minor

    Increased processing accuracy has been noted in otherwise healthy persons at 400mg PS daily when testing was conducted in a fatigued state (post exercise)

    CFish Oil

    Minor

    An improvement in processing accuracy (assessed by amount of errors in a cognitive test) has been noted with fish oil in otherwise healthy adults that do not frequently... show

    CBranched Chain Amino Acids

    Minor

    The increased processing accuracy appears to be secondary to reducing exercise-related fatigue, and occurs when testing is after exercise.
