Phosphatidylserine or PS is a nutrient that shows much promise in improving cognitive function in most people, but especially in the aged. PS belongs to a unique class of fat-soluble nutrients called phospholipids. PS is a building block for nerve cell membranes and through that revitalizes all nerve cell functions. Although it is contained in each cell membrane, PS is most highly concentrated in brain cells.
PS may benefit most people because we are all subject to free radicals formed from breathing in cigarette smoke, alcohol consumption, environmental pollution, and/or chronic emotional stress--factors that have a cumulative negative effect on the brain. PS can affect our mood as well. A double-blinded study on elderly women showed that PS helped their memory and their behaviour.
Natural Factors PS is derived from soy phospholipids. In clinical studies, plant-based PS is just as effective as animal-based PS with none of the concerns associated with prion (e.g. Mad Cow disease) diseases.
