In healthy adults, the concentration of choline in plasma ranges from 7 to 20 mcmol/L [2]. One study in 1,508 women found that those with diets high in free choline were 24% less likely to get breast cancer (55). [2], Choline is widespread in nature in living beings. Although actual deficiency is rare, many people in Western countries are not meeting the recommended intake. [53] In 1862, Strecker repeated his experiment with pig and ox bile, calling the substance choline for the first time after the Greek word for bile, chole, and identifying it with the chemical formula C5H13NO.

From this, the AIs for children and adolescents were extrapolated. 100% of the daily value means that a serving of food has 550mg of choline. Am J Clin Nutr 2016;104:173-80. For example, kidney dysfunction predisposes for cardiovascular diseases, but can also decrease TMA and TMAO excretion. Magn Reson Med 1998;39:1005-10. View abstract. Choline is the parent compound of the cholines class, consisting of ethanolamine residue having three methyl groups attached to the same nitrogen atom. One small study in 57 adults found that 77% of men, 80% of postmenopausal women and 44% of premenopausal women experienced liver and/or muscle damage after going on a choline-deficient diet (11). Medical conditions associated with low acetylcholine levels include Alzheimer's disease and myasthenia gravis. Dibaba DT, Johnson KC, Kucharska-Newton AM, Meyer K, Zeisel SH, Bidulescu A. PLoS One 2012;7:e43448. 2003;37(6):1231-1238. View abstract . Many foods also contain lecithin, a substance rich in phosphatidylcholine that is prepared during commercial purification of phospholipids; lecithin is a common food additive used as an emulsifying agent in processed foods, such as gravies, salad dressings, and margarine [1,3]. Gaur SN, Agarwal G, Gupta SK. [. Wurtman, R. J., Hirsch, M. J., and Growdon, J. H. Lecithin consumption raises serum-free-choline levels. 2011;53(1):115-19. [45][46], Choline uptake into the brain is controlled by a low-affinity transporter located at the bloodbrain barrier. Can.J.Neurol.Sci. It is neither a vitamin nor a mineral. Choline is an essential nutrient needed for proper liver, muscle, and brain functions; lipid metabolism; and cellular membrane composition and repair. Spector SA, Jackman MR, Sabounjian LA, et al. Choline is an 'essential' nutrient for humans; and similar to omega-3 fatty acids, as the amount produced endogenously (in the liver) is not sufficient to meet human requirements,6 it therefore needs to be obtained from dietary and supplement sources. 1950;39:729. It may play a key role in healthy brain function, heart health, liver function and pregnancy. View abstract. Davis, K. L., Hollister, L. E., Barchas, J. D., and Berger, P. A. Choline in tardive dyskinesia and Huntington's disease. [3], Choline is required to produce acetylcholine a neurotransmitter and S-adenosylmethionine (SAM), a universal methyl donor. This is exemplified by the observation that Pemt / mice (mice lacking functional PEMT) will abort at 910 days unless fed supplemental choline. Int.J.Sport Nutr.Exerc.Metab 2000;10(2):170-181. This is a neurotransmitter which plays a necessary role in muscle contraction, memory and neural development, for example. 2015;102(5): 1113-25. Here are 16 foods that are high in choline. View abstract. Other research suggests that higher dietary choline might increase cardiovascular disease risk because some choline and other dietary ingredients, such as carnitine, are converted to trimethylamine (TMA) by intestinal bacteria. Stoll, A. L., Sachs, G. S., Cohen, B. M., Lafer, B., Christensen, J. D., and Renshaw, P. F. Choline in the treatment of rapid-cycling bipolar disorder: clinical and neurochemical findings in lithium-treated patients. The risk of NAFLD was 32% lower in women in the highest quintile of choline intake (412 mg/day) compared to the lowest (179 mg/day) and 25% lower in men in the highest (452 mg/day) quintile compared to those in the lowest quintile (199 mg/day). Nasrallah, H. A., Dunner, F. J., Smith, R. E., McCalley-Whitters, M., and Sherman, A. D. Variable clinical response to choline in tardive dyskinesia. Acta Neurologica Scandinavica 1989;79(S121):27-42. J Biol Chem 2011;286:1649-58. Trimethylglycine in turn serves as a source of methyl groups by participating in the biosynthesis of S-adenosylmethionine. DRIs is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. The amount of choline that individuals need is influenced by the amount of methionine, betaine, and folate in the diet; gender; pregnancy; lactation; stage of development; ability to produce choline endogenously; and genetic mutations that affect choline needs [1,2,4,5]. Deficiency. 2012;64(3):481-487. So despite the increased production of choline, pregnant women end up low . [, Dalmeijer GW, Olthof MR, Verhoef P, Bots ML, van der Schouw YT. Neurons, conversely, acquire choline by both high- and low-affinity transporters. [, Higgins JP, Flicker L. Lecithin for dementia and cognitive impairment.

Maternal choline supplementation mitigates alcohol exposure effects on neonatal brain volumes. The federal government's 2020-2025 Dietary Guidelines for Americans notes that "Because foods provide an array of nutrients and other components that have benefits for health, nutritional needs should be met primarily through foods. Aberrant estrogen regulation of PEMT results in choline deficiency-associated liver dysfunction. Ziegler RG, Lim U. One-carbon metabolism, colorectal carcinogenesis, chemoprevention - with caution. Intake was 75127mg/day in infants, 151210mg/day in 1- to 3-year-olds, 177304mg/day in 3- to 10-year-olds and 244373mg/day in 10- to 18-year-olds. View abstract. Zeisel SH. Korzh, E. V. [The efficacy of inhalations of choline chloride in the treatment of patients with chronic dust-induced bronchitis]. Choline is a source of methyl groups needed for many steps in metabolism. Choline may boost memory function, improve brain development and treat anxiety and other mental disorders. [2], Hundreds of choline antagonists and enzyme inhibitors have been developed for research purposes. Buchman, A. L., Ament, M. E., Sohel, M., Dubin, M., Jenden, D. J., Roch, M., Pownall, H., Farley, W., Awal, M., and Ahn, C. Choline deficiency causes reversible hepatic abnormalities in patients receiving parenteral nutrition: proof of a human choline requirement: a placebo-controlled trial. Another observational study discovered that pregnant women with the lowest intakes were more than twice as likely to have babies with neural tube defects (62). 2001;25(1):30-5. Women who are pregnant or nursing thus have a greater need for choline. However, choline intake has not been shown to increase the risk of dying from cardiovascular diseases. [21], Insufficient data is available to establish an estimated average requirement (EAR) for choline, so the Food and Nutrition Board (FNB) established adequate intakes (AIs). Such factors may have not been properly accounted for in certain studies observing TMA and TMAO level related mortality. Davis, K. L., Hollister, L. E., Vento, A. L., and Simonton, S. Choline chloride in animal models of tardive dyskinesia. Only limited data are available on the use of choline to treat NAFLD. [15] In the hepatic PEMT route, 3-phosphoglycerate (3PG) receives 2 acyl groups from acyl-CoA forming a phosphatidic acid. Higher intakes of choline during pregnancy may reduce the risk of neural tube defects in babies. A study in more than 56,000 people found that normal-weight women with the highest intakes had a 28% lower risk of liver disease, compared to those with the lowest intakes (51). View abstract. The body needs choline to synthesize phosphatidylcholine and sphingomyelin, two major phospholipids vital for cell membranes. In addition, low choline intake may raise your risk of other pregnancy complications. Gut microbes degrade the unabsorbed choline to trimethylamine, which is oxidized in the liver to trimethylamine N-oxide. Zeisel, S. H., Epstein, M. F., and Wurtman, R. J. Elevated choline concentration in neonatal plasma. 11th ed. In addition, a single 3-ounce (85-gram) serving of beef kidney or liver can supply all of a womans daily requirement and most of a mans (23). In: H. SM, Caudill MA, eds. View abstract. Nutrients 2017;9(7). [8], In humans, choline is oxidized irreversibly in liver mitochondria to glycine betaine aldehyde by choline oxidases. [21], DV = Daily Value.

However, a more recent analysis of data on 80,978 women from the Nurses Health Study and 39,434 men from the Health Professionals Follow-Up Study found an increased risk of mortality in those consuming higher levels of choline [33]. 2003;13(3):245-251. [8] Individual EU countries may have more specific recommendations. [8] Trimethylglycine is a necessary osmoregulator. It's also important during pregnancy to support fetal brain development. [21] "Total choline" is defined as the sum of free choline and choline-containing phospholipids, without accounting for mass fraction.
