Phosphatidylserine (PS) belongs to a class of nutrients called phospholipids, which are fats that play an integral role in cell membrane function and structure.

We need our membranes to filter nutrients in and out, to communicate with other cells, and to regulate cell growth. PS is crucial for the maintenance of healthy cell membranes throughout the body, but it’s most highly concentrated in the nerve cells of our brains.

Natural Factors uses Sharp-PS® GREEN, a highly absorbable and stable form of PS that is 100% soy-free, derived from non-GMO sunflower oil.
