Phosphatidylserine (PS), a phospholipid, and DHA, an omega-3 fatty acid, are major components of cell membranes, particularly the membranes of nerve cells. They facilitate the electric signals that are the basis of neuron communication, supporting memory, mood, concentration, stress control and other cognitive functions. This DHA conjugate form of PS is believed to increase the delivery of this vital compound to the brain, supporting advanced brain protection and enhanced cell function.
