What is phosphatidylserine (PS)?
Phosphatidylserine is a natural phospholipid that constitutes an important component of cell membranes.
It exists in large amounts in brain nerve cells and is called “brain nutrients.” About 50% of the dry weight of the nerve cell membrane of the human brain is phospholipids.
