Phosphatidylserine for Attention & Focus Difficulties
C Some Evidence Limited evidence from small studies, but some positive signals exist.Research suggests phosphatidylserine may help support focus and reduce behaviors associated with attention difficulties, particularly in stressed individuals.
The Bottom Line
Research suggests phosphatidylserine may help support focus and reduce behaviors associated with attention difficulties, particularly in stressed individuals.
