"Choline is the precursor molecule for the neurotransmitter acetylcholine, which is involved in many functions including memory and muscle control. Choline must be consumed through the diet for the body to remain healthy. It is used in the synthesis of the constructional components in the body's cell membranes. Despite the perceived benefits of choline, dietary recommendations have discouraged people from eating certain high-choline foods, such as eggs and fatty meats. The 2005 National Health and Nutrition Examination Survey stated that only 2% of postmenopausal women consume the recommended intake for choline."

"Although its entire mechanism of action, particularly how it interacts with other nutrients, is not completely understood, it seems to often work in concert with folate and an amino acid called methionine. Although the human body can make some choline it is generally recognized that it is important to get dietary choline as well. "

"Although choline is not by strict definition a vitamin, it is an essential nutrient. Despite the fact that humans can synthesize it in small amounts, choline must be consumed in the diet to maintain health. The majority of the body's choline is found in specialized fat molecules known as phospholipids, the most common of which is called phosphatidylcholine or lecithin."

"Food sources of choline include soybeans, egg yolk, butter, peanuts, potatoes, cauliflower, lentils, oats, sesame seeds and flax seeds."
