Product Information


ANDREW LESSMAN'S Phosphatidyl Serine 100 provides a concentrated source of the brain's most defining phospholipid. Phosphatidyl Serine (PS) is present in all cell membranes; however, it is in the brain where it is most highly concentrated and its benefits most apparent. Unfortunately, there are no good dietary sources of PS, so its independent benefits are only available via supplementation. Given Phosphatidyl Serine's high concentration in healthy brain structure, it is not surprising that PS plays a vital role in normal brain function. PS is essential for the production and release of neurotransmitters – those vital molecules that are required for all brain functions, such as thought, memory and concentration. PS has received the greatest attention given its role in a healthy response to certain forms of stress, along with supporting positive mood. PS is a natural addition to any modern wellness and anti-aging strategy, since life can often seem like a series of stressful experiences and a more positive response to stress would be highly desirable. Our Phosphatidyl Serine 100 provides a natural tool to help promote our body's healthy, positive response to stress while supporting healthy brain function, including positive mood and mental clarity.
