Amidst the global aging population, there is a heightened awareness of age-related cognitive decline, prompting an increasingly proactive search for solutions that support memory, attention, and overall brain function. Consequently, the interest in nootropics and cognitive supplements is experiencing a significant upsurge.

As a naturally occurring substance, citicoline（CDP-choline） is typically produced in the human brain. It is composed of cytidine, choline, pyrophosphate, and ribose, and serves as a precursor for the synthesis of structural membrane phospholipids. 

The choline component within it can be used for the synthesis of acetylcholine, which possesses neuroprotective effects. These effects contribute to the protection and repair of cells, structures, and functions within the nervous system.

Citicoline can be used as a prescription medication and is also widely used in dietary supplements and food beverages to enhance cognitive abilities and memory.

For medical purposes in the treatment of brain-related conditions, it can be administered to patients in various forms, such as injections, oral formulations, and eye drops, to aid in the treatment of strokes, brain dysfunction resulting from accidents, glaucoma, and other such conditions.

At present, citicoline is increasingly being adopted as a functional ingredient and dietary supplement, primarily to support the enhancement of cognitive abilities in middle-aged and older adults, as cognitive functions tend to decline with age.

Additionally, it can be incorporated into food and beverages, primarily targeting young individuals who are in learning or working environments. It aids these individuals in enhancing memory retention, maintaining brain health, and improving focus and work efficiency.
