Choline makes acetylcholine, which is an important neurotransmitter needed for brain and memory function. In fact, scientists are now researching the possibility that choline may be beneficial in treating and even preventing diseases that affect the brain and central nervous system, such as Parkinson’s disease and Alzheimer’s (people with Alzheimer’s usually have low levels of acetylcholine in their brains). And recent studies show that choline is also extremely important for ensuring healthy brain function in newborns.
