Phospholipids are the structural building blocks of cell membranes. Phosphatidylcholine (PC): most abundant — liver support, bile production, cell membrane. Phosphatidylserine (PS): brain function — see phosphatidylserine.md. Phosphatidylethanolamine (PE): cell signaling. Phosphatidylinositol (PI): second messenger systems. Sources: egg yolk, soy lecithin, sunflower lecithin, krill oil. 300-900mg/day from lecithin. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
