The Active Ingredient Is: Phosphatidylserine (PS)
Phosphatidylserine is essentially a phospholipid that forms part of cell membranes and supports normal neuronal membrane integrity and signaling.
This formulation derives the phospholipid complex from non-GMO soy lecithin, with phosphatidylserine presenting as the primary active component alongside phosphatidylcholine and phosphatidylethanolamine to support membrane composition.
What Does Phosphatidylserine Do?
Scientific research shows phosphatidylserine may support memory, learning, and attention, and it may influence mood and stress-related responses in older adults.
In line with EFSA-style understanding, PS participates in cellular communication in the brain and helps maintain neurotransmitter function, contributing to normal cognitive processes. A cited study indicates improvements in memory scores with PS use in older adults.
Dr. Glade of a university research group found that phosphatidylserine supports learning and memory retention in aging populations.
