Product insights

  • Phosphatidylserine (PS) is a crucial phospholipid and a key building block of brain cell membranes, vital for maintaining optimal brain function and cell-to-cell communication.
  • PS enhances cognitive function by increasing cell membrane fluidity, which facilitates efficient neurotransmitter signaling and supports overall neuronal health.
  • Supplementation with Phosphatidylserine supports healthy cortisol regulation by modulating the release of ACTH in the brain, helping to blunt cortisol spikes during periods of stress.
  • PS exhibits antioxidant activity, protecting brain cells from damage caused by free radicals and supporting long-term cognitive health.

Suggested use

The research

2 cited studies
1.
Cognitive Function in Aging

Research indicates that phosphatidylserine supplementation can improve cognitive function, particularly in the aging brain, by supporting neuronal membrane integrity and neurotransmitter activity.

2.
Stress Response Modulation

Studies suggest that PS can modulate the body's stress response by influencing cortisol levels, potentially benefiting individuals experiencing chronic stress.
