A blend of choline, uridine, and docohexaenoic acid (DHA) serves as precursor to lipid molecules essential for forming and maintaining membranes of brain cells, thereby helping to avert the loss of synapses—connections between brain cells that can lead to memory loss and other cognitive impairments.

Choline can be found in meats, nuts and eggs, and omega-3 fatty acids are found in a variety of sources, including fish, eggs, flaxseed and meat from grass-fed animals. Uridine is produced by the liver and kidney, and is present in some foods as a component of RNA. Docohexaenoic acid (DHA) is an omega-3 fatty acid, best known for its role in promoting cardiovascular health. Richard Wurtman, from Massachusetts Institute of Technology (MIT; Massachusetts, USA), and colleagues submit that these three nutrients are precursors to the lipid molecules that, along with specific proteins, make up brain-cell membranes, which form synapses. To be effective, all three precursors must be administered together. The researchers followed 259 patients for six months. Patients, whether taking the nutrient blend or a placebo, improved their verbal-memory performance for the first three months, but the placebo patients deteriorated during the following three months, whereas the nutrient blend patients continued to improve. Further, electroencephalography (EEG) studies revealed changes in brain-activity patterns throughout the study: as the trial went on, the brains of patients receiving the nutrient blend started to shift from patterns typical of dementia to more normal patterns. Because EEG patterns reflect synaptic activity, the researchers submit that synaptic function increased following treatment with the nutrient blend.
