There are special fats in your body that perform different functions. Phosphatidylserine is the fatty substance that covers and protects the cells in your brain. Brain cells direct synaptic currents between them and phosphatidylserine aids in this process. So scientists now believe that phosphatidylserine plays an important role in keeping your mind and memory sharp.
Animal studies show that as a person or animal ages, the amount of phosphatidylserine decreases, making it harder for us to think clearly and remember things. However, by supplementing with phosphatidylserine, scientists believe we can preserve our memory and cognitive abilities for longer.
A Japanese study of soy-derived phosphatidylserine showed improvement in memory function for patients after a 6-month placebo-controlled study. During the study, both the patients who received placebo and those who took phosphatidylserine showed an initial improvement in memory. After that, the improvement in the placebo group waned and the patients taking phosphatidylserine continued to improve.
A literature review by American researchers concluded that phosphatidylserine is essential for healthy nerve cell membranes and mylein. They claim that phosphatidylserine supports human cognitive functions, including short- and long-term memory, new memories, retrieving memories, and focusing attention. They also found that it promotes concentration, reasoning, problem solving and communication. It is even important for motor functions such as reflexes.
