Scores of research studies since the 1980s have pointed to an important role for the “brain cell nutrient” phosphatidyl serine (pronounced fos-fa-tie-dil see-reen) as a dietary supplement in support of brain functions such as memory and mental sharpness.
What is phosphatidyl serine (PS)? It is made naturally by the body, is most concentrated in the brain, and works in the cell’s energy-producing mitrochondia to support cell function, the integrity of the cell membrane, and inter-cell communication. It is a basic component of cell membranes, which – in nerves and the brain especially – generate and relay electrical currents from cell to cell. This activity tends to fall off starting in middle age.
