Phosphatidylserine: a synthesized substance derived from natural sources
Phosphatidylserine is a phospholipid, a fatty substance found in brain cell membranes—the bilayer structures that support and protect the interior of the cell. It is credited with a range of nootropic benefits, including memory and cognitive functions.
How it works:
Phospholipids are fats that contain the mineral phosphorus, an essential part of bones, teeth, and DNA. Phosphatidylserine facilitates neural communications in the brain and protects nerve cells. The FDA has determined that phosphatidylserine derived from sunflower seeds, soy lecithin, and fish is generally recognized as safe (GRAS), although it is not approved for treating medical conditions.
What it can do:
- Marketed as a nutritional supplement, phosphatidylserine is claimed to promote cognitive function and memory, especially with age, and to enhance the intracellular metabolism of glucose.
- Some individuals take it as an anti-aging supplement, believing it will increase their brain’s natural phosphatidylserine level.
- It is also thought to help support attention and focus, relieve stress, and improve sleep.
