What is Phosphatidylserine?

Phosphatidylserine (PS) is a phospholipid that is a key component of cell membranes, particularly abundant in brain tissue. It plays a crucial role in maintaining cellular function, supporting cognitive health, and facilitating cell-to-cell communication. Phosphatidylserine is naturally found in foods like soy lecithin, sunflower lecithin, and bovine brain tissue, and is widely used as a dietary supplement for brain health and cognitive support.

Key Benefits

  • Cognitive Support: Supports memory, learning, concentration, and overall cognitive function, particularly in aging individuals.

  • Stress Management: May help regulate cortisol levels and support the body's response to physical and mental stress.

  • Cell Membrane Health: Essential component of cell membranes, supporting cellular integrity and communication throughout the body.

  • Athletic Performance: May support exercise recovery and reduce exercise-induced muscle damage and soreness.

  • Mood Support: Plays a role in neurotransmitter function, potentially supporting healthy mood and emotional well-being.
