Phosphatidylethanolamine is a phospholipid that makes up cell membranes, especially in the brain and nervous system. It helps maintain cell structure and supports signaling between cells.
People sometimes lump it together with phosphatidylserine, but human research on phosphatidylethanolamine for memory or mood is thin. Most of what we know comes from lab work and animal studies.
Take it with food to help your body absorb it. No standard dose exists.
In theory, some phospholipids can interact with blood thinners, though the evidence for phosphatidylethanolamine is sparse. Talk to a healthcare provider before using it if you take any medication or are pregnant or nursing.
