Popular nutritional support for maintaining healthy brain and cognitive function Features clinically-researched Sharp-PS phosphatidylserine Just one softgel per day for reliable support The cells of your brain are sheathed and protected by an outer membrane that is full of an important fatty substance called phosphatidylserine, or simply PS. We don’t get PS from food; rather, our bodies intuitively make the right amount to keep brain cells healthy. However, production declines over time. The clinically-researched Sharp-PS in our new Triple-Strength Phosphatidylserine supplement can help support cognitive health with just one softgel per day.
