  • Supports healthy memory and thinking ability  
  • Supports mood and stress 
  • Support healthy brain activity 


Phosphatidyl Serine is essentially known for enhancing cell-to-cell communication and supporting healthy cognitive function. Phosphatidyl Serine (PS) is derived from soybean lecithin and can be regarded as structural components of brain neurons. Commonly known by its abbreviation PS, this nutrient is a vital lipid for memory, mood, and stress. PS is a molecular building block for life that supports healthy memory and thinking ability.


Features at Glance:

  • Reduces stress
  • Helps manage mood
  • Augments thinking ability
  • Aids learning ability and cognitive function
  • Supports body during mental and physical stress
  • Effective in treatment for senile dementia, Alzheimer’s, depression



  • Supports mental enhancement - aids learning ability and cognitive function
  • Supports body during mental and physical stress – may help to lower excessive levels of cortisol
  • Support for senile dementia, Alzheimer’s, depression, poor memory, mental and physical stress
  • Safe for younger and older adults


How does it work?

PS is a vital lipid for memory, mood and stress. The phospholipid structure incorporates essential fatty acids, including Omega 3 DHA and EPA. These substances enable us to make energy from our foods and support our life processes. PS is a molecular building block for life; it is essential for creating the membranes that make our cells work.


Supports healthy memory and thinking ability

PS has been shown to support healthy brain activity and enhance cognitive function in both younger and older adults. This is due to PS being involved in many functions including enhancing cell membrane fluidity, increasing the number of acetylcholine receptors, keeping fatty substances in the brain in a soluble state and helping to ‘untangle’ nerve pathways in the brain.


Supports mood and stress

Studies have shown positive effects on the stress response. PS may help to reduce cortisol in response to stress by supporting the hypothalamic and pituitary membrane structures. Studies have shown support for mood elevation in younger and older adults via the ability of PS to enhance neurotransmitter activity. 


Suggested Use: Take one softgel 3 times daily with meals.

What is Phosphatidyl Serine made from?

PS is derived from soybean lecithin which provides the essential brain nutrient phosphatidylserine.


Have there been any studies on PS?

PS is one of the most intensively studied dietary supplements. Over several decades, besides the many double-blind trials, there have been over a hundred other human studies, and thousands of 'basic science' papers published on PS. Trials documented benefits from PS in the areas of memory, learning, comprehension, mood, anxiety and coping with stress. 


How does PS benefit stress as well as benefiting mood?

As well as its proven benefits for memory, learning and other cognitive functions, PS can benefit stress management. Human and animal studies suggest PS helps increase the sensitivity of neurotransmitter receptors in nerve cell membranes. Thus showing improved measures of mood, anxeity, irritability and sociability.
