Ceraxon ® is a pharmaceutical preparation of CDP-choline (Citicoline), a choline-containing phospholipid. It is one of the most efficient supplemental forms of choline along with Alpha-GPC (Cereton).
Choline is a nutrient crucial for cognitive performance, which is normally obtained from the diet. It was first discovered in 1862, but its role in neurology remained unknown for some time. Since 1998, choline was recognized as an essential nutrient by the Institute of Medicine, as human body cannot synthesize it on its own.
Because people tend to avoid cholesterol-rich food which is also usually rich in choline, most of the population is believed to be choline-deficient. Deficiency of choline may lead to fatty liver disease, atherosclerosis, and various neurological disorders. The use of some nootropic drugs such as Piracetam and Noopept might also require an additional choline supplementation.
CDP-choline is used in the medical practice of many countries around the world including Japan, Russia, France, and Switzerland. Indications for use include stroke, traumatic brain injuries, and organic brain syndrome. Citicoline works by increasing the synthesis of phosphatidylcholine (the primary component of neuronal cell membranes) and acetylcholine – a major neurotransmitter involved in cognitive functioning.
Various forms of choline are also often used as cognitive enhancing supplements. However, cheaper forms such as Lecithin and Choline salts have limited nootropic value, as they have a less pronounced cholinergic effect and no impact on monoaminergic neurotransmission.
