Phosphadidyl serine does all this through the following actions: PS stimulates the release of dopamine (a mood regulator that also controls physical sensations and movement), increases the production of acetylcholine (necessary for learning and memory), enhances brain glucose metabolism (the fuel used for brain activity), reduces levels of cortisol (a stress hormone), and boosts the activity of nerve growth factor, which oversees the health of cholinergic neurons. The nerve cell membrane is the site where molecules of sodium and potassium exchange electrons, causing the electrical impulse to be generated. This bioelectric current then travels along the membrane to trigger the release of neurotransmitters. These are the chemical messengers that cross synapses (gaps between nerve cells) to relay information to neighboring nerve cells. This sets other electrical currents in motion -- along thousands of other nerve cells. This happens billions of times each second, and is how the brain and nerves coordinate and communicate with the rest of the body. Phosphatidyl Serine has a very important function in the nerve cell membrane. As a key bio-structural molecule, PS provides vital support for the membrane proteins that enable nerve cells to communicate and grow.
