CDP-Choline, also known as Citicoline, is an endogenous compound found naturally in the body. It plays a crucial role in cell membrane synthesis and neuronal function. As a supplement, it is often marketed for its potential cognitive-enhancing properties, particularly in areas related to memory, focus, and overall brain health. CDP-Choline is a psychostimulant/nootropic that acts as an intermediate in the biosynthesis of phosphatidylcholine, a major component of neuronal cell membranes. It is composed of cytidine and choline, which are released upon oral intake and then recombine in the brain to form CDP-Choline (NIH ODS). It is available as an over-the-counter supplement, typically in capsule or powder form.
