Phosphatidylcholine is a major phospholipid in cell membranes and a source of choline; lecithin (from soy or sunflower) is a phospholipid mixture rich in it, widely used as a food emulsifier.
It is taken for liver and cognitive support and to supply choline. The evidence is preliminary — some interest in liver health and as a choline source — and most people get phospholipids and choline from food. A reasonable choline source rather than a proven therapy.
