Phosphatidylserine (PS) is a naturally occurring aminophospholipid found in high concentrations in the brain. The human body can make phosphatidylserine in small amounts, but it is mostly obtained from the foods we eat. QFocus contains Sharp PS (R), a type of phosphatidylserine that compared to other types has a higher absorbability and functioning.


Phosphatidylserine has a positive impact on the endurance of the brain cells, which means the cells can work faster for a longer period. This way, the intake of Phospatidylserine has a favorable effect on the concentration and focus during activities at which the brain needs to go to the limit. Phosphatidylserine slows down the increase of the stress hormone during taxing mental activities, which reduces the feeling of stress.


  • Increases mental capacity
  • Provides necessary brain supporting nutrients
  • Helps sustain a desired cognitive state
