Choline is an essential nutrient that plays a vital role in various bodily functions, including brain development, liver function, and muscle movement. It is a precursor for the neurotransmitter acetylcholine, which is important for memory and muscle control. The body can produce some choline, but it often needs to be obtained from dietary sources. Good sources of choline include foods like eggs, meat, fish, and certain vegetables such as broccoli and cauliflower. The recommended daily intake varies by age and gender, but many people do not get enough choline in their diets, which can lead to health issues over time.
