| Choline and pantothenic acid are substances needed by the brain to produce acetylcholine, a major brain/motor neuron neurotrans-mitter that facilitates the transmission of impulses between neurons. Choline chloride and phosphatidylcholine are two forms of choline that have been the subject of most of the research, some of which has shown that high doses of choline are an effective way of achieving optimal acetylcholine levels. Lower levels of acetylcholine are associated with memory loss and learning difficulties that occur in aging brains.* CDP-choline stands for cytidine-5-diphosphocholine. This unique form of choline readily passes through the blood-brain barrier directly into the brain tissue. Once past the blood-brain barrier, CDP-choline maintains the normal synthesis of critical components in cell membranes, and promotes optimal cerebral energy metabolism.* |
