Formerly Cerenx Brain Support (sodium citicoline) is a medical food product indicated for the distinct nutritional needs of those experiencing age-related cognitive decline and related concerns. Citicoline, also known as CDP-Choline, is an endogenous nucleotide involved in brain energy metabolism. Citicoline is available in 65 countries and is approved as a prescription medication in some European countries and throughout Asia. The National Health and Nutrition Examination Survey (NHANES) shows that only 8% of US adults consume the recommended amount of choline on a daily basis. Citicoline is a source of dietary choline that provides additional benefits beyond choline supplementation, including the generation of phospholipids and support of phospholipid metabolism. Unfortunately, CDP-choline is only available in small amounts in food.
