PS•IQ Memory is a unique formula comprised of phosphatidylserine (PS), EPA and DHA from fish oil, and GLA and LA from evening primrose oil. These omega-3 and omega-6 essential fatty acids work synergistically with PS to optimize brain function, influencing the integrity and fluidity of cell membranes, as well as supporting a multitude of neural activities. The formula also contains naturally occurring phosphatidylcholine (PC), a major structural component of the cell membrane. PS and essential fatty acids are important components of our brain cells. Research shows that PS enhances our ability to learn, think, and remember, while DHA is crucial to brain growth and development, and to protecting and maintaining normal brain function as we age. EFAs help control inflammation and improve memory function and mood, as well as benefit the cardiovascular system. Unfortunately, as we get older our production of PS decreases, which can contribute to cognitive decline. Research shows that PS supplementation supports brain function and revitalization – especially with respect to tasks that require memory, vocabulary, and concentration – as well as improving mood and reducing stress. Natural Factors uses Sharp-PS® GREEN, a highly absorbable and stable form of PS derived from non-GMO sunflower oil that is 100% soy-free.
