PS-100 (phosphatidylserine)



Phosphatidylserine, commonly called the “brain nutrient,” promotes cognitive function, emotional well-being, memory, and behavioral performance by supporting cell membrane composition.

Phosphatidylserine is a phospholipid found in all cells, but is most concentrated in brain cells. It supports cognitive function, emotional well-being, and behavioral performance. It has also been shown to support healthy memory. In a double-blind, placebo-controlled, multicenter study of 425 individuals, daily supplementation of phosphatidylserine over six months resulted in statistically significant support of positive behavioral and cognitive functions. In a placebo-controlled investigation of 149 subjects, the group receiving phosphatidylserine scored higher than placebo in performance tests related to memory tasks of daily life. Phosphatidylserine is often used in correcting adrenal fatigue / HPA-axis dysregulation, particularly when cortisol levels are chronically elevated as shown on diagnostic lab tests. Preliminary scientific research suggests that phosphatidylserine may reduce the risk of dementia in the elderly.
