CDP-Choline, also known as citicoline, is a water-soluble precursor to choline, meaning it is converted to choline upon ingestion  . In the brain, choline is critical for the synthesis of acetylcholine, a neurotransmitter that plays an active role in learning and memory . Thus, CDP-Choline is often taken to support cognition.
The “CDP” component of this compound converts to uridine once crossing the blood-brain barrier where it increases brain cell ATP– an important promoter for neuron growth and repair . While choline can be naturally obtained through a variety of foods such as eggs, fish, and peanuts, CDP is much more difficult to find in our diets . Choosing to supplement with CDP-Choline is a popular practice for those who are also supplementing with a Racetam, since the two nootropic types work synergistically to improve cognition.
