Product Description

Phosphatidylcholine is a type of phospholipid that is a major component of cell membranes. It is composed of a glycerol backbone, two fatty acid chains, a phosphate group, and a choline molecule. Phosphatidylcholine is essential for the structure and function of cell membranes, as it helps maintain their integrity and fluidity.

In addition to its role in cell membranes, phosphatidylcholine also serves as a precursor for the synthesis of the neurotransmitter acetylcholine, which is involved in various cognitive functions. It is also involved in the transport of lipids in the bloodstream and plays a role in liver function and fat metabolism.

Phosphatidylcholine can be obtained from dietary sources such as eggs, soybeans, and sunflower seeds. It is also available as a dietary supplement and is sometimes used for its potential health benefits, including liver support, brain function, and cardiovascular health.

Certificate of Analysis


  1. Structural component: Phosphatidylcholine is a major component of cell membranes, helping to maintain their integrity and fluidity. It forms a lipid bilayer that acts as a barrier between the cell’s internal environment and the external environment.
  2. Emulsifier: Phosphatidylcholine has emulsifying properties, meaning it can mix with both water and fat. This property allows it to help transport and solubilize dietary fats in the digestive system, aiding in their absorption.
  3. Source of choline: Choline is an essential nutrient that is required for various processes in the body, including the synthesis of neurotransmitters like acetylcholine. Phosphatidylcholine serves as a major dietary source of choline, which can be converted into acetylcholine in the brain.
  4. Liver health: Phosphatidylcholine is involved in the metabolism of fats in the liver. It helps transport fats out of the liver and prevents the accumulation of fat deposits, which can lead to liver damage.
  5. Brain function: As mentioned earlier, choline derived from phosphatidylcholine is used in the synthesis of acetylcholine, a neurotransmitter that is important for memory, learning, and cognitive function. Phosphatidylcholine has also been studied for its potential role in improving cognitive function and reducing the risk of age-related cognitive decline.
  6. Lung surfactant: Phosphatidylcholine is a major component of lung surfactant, a substance that helps reduce surface tension in the lungs and prevents their collapse during breathing.
