Eggs, liver, and certain seafoods top the list of choline-rich foods, but most people fall well short of getting enough. Only about 8% of American adults meet the adequate intake for choline, a nutrient essential for brain function, liver health, and fetal development. Knowing which foods deliver the most choline can help you close that gap.
How Much Choline You Need
The adequate intake for choline is 550 mg per day for adult men and 425 mg for adult women. During pregnancy, the target rises to 450 mg, and during breastfeeding it increases to 550 mg. Children need less, ranging from 125 mg for toddlers up to 375 mg for teenagers, depending on age.
A food is considered a “good source” of choline if it provides at least 55 mg per serving, and “high in choline” if it delivers 110 mg or more. Most Americans get nowhere near enough. National survey data from 2017 found that roughly 92% of adults and 91% of pregnant women fail to meet the adequate intake. Eggs and protein-rich foods were the strongest predictors of actually hitting the target.
The Richest Sources: Eggs and Organ Meats
Egg yolks are the single most concentrated common source of choline in the food supply, containing about 680 mg per 100 grams. In practical terms, one large hard-boiled egg provides 147 mg of choline, which is roughly a quarter to a third of a day’s worth depending on your sex. Almost all of that choline sits in the yolk, so egg-white omelets won’t help here. Two eggs at breakfast gets you close to 300 mg before you’ve eaten anything else.
Organ meats, especially liver, come in a close second. Beef liver delivers 420 to 430 mg per 100 grams when cooked, and chicken liver provides around 290 to 330 mg per 100 grams. Veal liver falls in a similar range. A single 3-ounce serving of beef liver can supply more than the entire daily target for most adults. If you eat liver even once a week, your choline intake is likely in good shape.
Other Animal-Based Sources
Beyond eggs and liver, several common proteins contribute meaningful amounts of choline. Beef, chicken breast, pork, and turkey all contain choline, though at lower concentrations than organ meats. A typical 3-ounce serving of cooked beef or chicken provides roughly 60 to 100 mg.
Fish and shellfish are also worth noting. Salmon, cod, and shrimp each contribute moderate amounts per serving. Dried smelt, a traditional food in some Alaska Native communities, packs about 300 mg per 100 grams, putting it on par with liver. Dairy products like milk and yogurt contain some choline as well, though you’d need several servings to make a significant dent.
Plant-Based Sources of Choline
Getting enough choline on a vegetarian or vegan diet is harder but not impossible. The best plant sources include soybeans and soy-based products like tofu and edamame. Cruciferous vegetables, particularly Brussels sprouts, broccoli, kale, collards, and bok choy, contribute choline in smaller but useful amounts. Legumes like kidney beans, navy beans, and peas add to your total as well.
Potatoes and shiitake mushrooms are two often-overlooked sources. Quinoa and wheat germ also contain modest amounts. The challenge with plant-based choline is concentration: you need to eat larger portions and a wider variety to approach what a couple of eggs deliver. People following a strictly plant-based diet may want to track their intake more carefully or consider a supplement.
Why Choline Matters for Your Brain
Your body uses choline to build acetylcholine, a neurotransmitter involved in both muscle control and memory. Acetylcholine acts at the junction between motor nerves and skeletal muscles, making it essential for every voluntary movement you perform. In the brain, it plays a direct role in learning and memory. The deterioration of acetylcholine-producing pathways in the brain is one of the hallmarks of Alzheimer’s disease, and drugs that block acetylcholine receptors are known to cause memory impairment.
The rate at which your body can produce acetylcholine depends partly on how much choline is available. During periods of high neural activity, your brain ramps up choline uptake to keep pace with demand. This means dietary choline isn’t just a background nutrient; it’s an active ingredient in cognitive performance.
Choline and Liver Health
Choline is a required building block for phospholipids, which form the structural backbone of every cell membrane in your body. One of its most critical jobs involves the liver: choline helps package and export fat out of liver cells. Without enough choline, fat accumulates in the liver, a process that can lead to non-alcoholic fatty liver disease. This connection is well established enough that researchers use choline-deficient diets to deliberately induce fatty liver in lab studies.
The Importance During Pregnancy
Choline’s role in fetal brain development is one of the strongest arguments for paying attention to intake. In a controlled feeding trial, infants born to mothers who consumed 930 mg of choline per day during the third trimester showed faster information processing speed compared to infants whose mothers consumed 450 mg per day. Researchers measured the babies’ reaction times at 4, 7, 10, and 13 months of age, and the higher-choline group performed better at every time point.
Animal research helps explain why. In developing rodent brains, low choline availability reduced the proliferation of new brain cells in the hippocampus, the region central to memory formation. It also increased cell death and impaired blood vessel growth in the same area. Conversely, higher choline during pregnancy enhanced the hippocampus’s capacity for a process called long-term potentiation, essentially its ability to strengthen connections between neurons. Remarkably, this benefit persisted well into the animals’ later life, not just during infancy.
Despite this evidence, only about 8.5% of pregnant women in the United States meet the adequate intake for choline. The average intake among pregnant women hovers around 319 mg per day, well below the 450 mg target.
Practical Ways to Boost Your Intake
The simplest strategy is to eat whole eggs regularly. Two eggs per day provide close to 300 mg of choline, covering more than half the daily target for most adults. Pairing eggs with a side of broccoli or beans at a meal adds another 30 to 50 mg.
If you’re comfortable eating organ meats, even a small serving of liver once a week makes a dramatic difference. For those who find the taste too strong, chicken liver pâté or liverwurst can be more palatable options. Incorporating soybeans, edamame, or tofu into a few meals each week helps bolster intake, especially for people limiting animal products.
Because choline is spread across so many different foods in modest amounts, variety works in your favor. A diet that includes eggs, some meat or fish, beans, and cruciferous vegetables on a regular rotation will generally get you close to the target without needing to obsess over numbers.
