Phosphatidylcholine is a chemical found naturally in all cells in the body. It is a source of the essential nutrient, choline. It's also found in foods.
Phosphatidylcholine is a major part of lecithin, which is a mixture of fats that are essential to cells in the human body. It's found in soy, sunflower, mustard, and eggs. The body makes a chemical called acetylcholine from phosphatidylcholine. Acetylcholine is important for memory.
People use phosphatidylcholine for inflammatory bowel disease. It is also used for acne, memory loss, Alzheimer disease, liver disease, and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse phosphatidylcholine with Alpha-GPC, choline, lecithin, phosphatidylserine, or soy. These are related but not the same.
