以前有报道称，补充磷脂酰丝氨酸（PS）可以减缓运动应激时皮质醇的释放，并改善情绪。本研究通过考虑PS补充剂是否会影响压力的主观感受和进行压力心算任务时心率的变化来扩展这些观察结果。在年轻人中，神经质得分高于而不是低于中位数，每天服用300 mg PS持续一个月与压力减轻和情绪改善有关。该研究首次报告了年轻健康成年人亚组补充PS后情绪的改善。
There have been previous reports that supplements of phosphatidylserine (PS) blunted the release of cortisol in response to exercise stress and that it improved mood. The present study extended these observations by considering whether PS supplementation influenced subjective feelings of stress and the change in heart rate when a stressful mental arithmetic task was performed. In young adults, with neuroticism scores above rather than below the median, the taking of 300 mg PS each day for a month was associated with feeling less stressed and having a better mood. The study for the first time reports an improvement in mood following PS supplementation in a sub-group of young healthy adults.
