The foods highest in choline — the nutrient your brain depends on to build acetylcholine, the neurotransmitter behind memory and learning — are beef liver, eggs, salmon, and certain legumes. A single three-ounce serving of beef liver delivers 356 mg of choline, covering roughly 65 percent of a man’s daily needs, while one large egg provides 147 mg, making it one of the most accessible choline sources for people who will never touch organ meat. These are not exotic superfoods. They are ordinary groceries that most people are simply not eating enough of. That matters more than most realize.
Approximately 90 percent of Americans fall short of the recommended daily intake for choline, according to the NIH Office of Dietary Supplements. NHANES data from 2015 to 2018 found that women averaged just 284 mg per day and men 390 mg — well below the adequate intake of 425 mg and 550 mg, respectively. Only 6 percent of women and 11 percent of men exceeded those targets. For a nutrient directly tied to memory, mood, and brain structure, that gap deserves attention. This article covers exactly why choline is so critical for the aging brain, what the latest research from 2024 and 2025 says about choline and cognitive decline, a ranked list of the best food sources, the real limitations of supplements versus dietary choline, and how to realistically build choline-rich meals without overhauling your entire diet.

Why Does Your Brain Need Choline-Rich Foods to Function?
Choline serves as the raw material your body uses to manufacture acetylcholine, a neurotransmitter essential for memory, mood, muscle control, and a range of other nervous system functions. When acetylcholine levels drop, the consequences show up as forgetfulness, difficulty concentrating, and in more severe cases, the progressive memory loss associated with Alzheimer’s disease. People with Alzheimer’s have been found to have lower levels of the enzyme that converts choline into acetylcholine, which supports the theory that maintaining higher dietary choline may help protect against cognitive decline over time. The connection between choline and brain health is not speculative. The Framingham Offspring Cohort study found that higher choline intakes were associated with better verbal and visual memory, as well as smaller white matter hyperintensity volume — a marker of small-vessel brain disease that often shows up on brain scans years before dementia symptoms appear.
A 22-year prospective cohort study out of China, published in 2024 in the journal Nutrients, confirmed that higher dietary choline intake was beneficial for cognitive function and delayed cognitive decline over more than two decades of follow-up. To put this in practical terms, consider two people in their sixties. One eats eggs for breakfast several times a week, includes salmon or chicken regularly, and occasionally has beans as a side dish. The other relies heavily on toast, cereal, and pasta — foods that contain very little choline. Over years, the difference in cumulative choline intake could be substantial. The research suggests that difference may show up not just in lab results but in how clearly each person thinks and remembers as they age.
What the Latest Research Reveals About Low Choline and Brain Decline
Two studies published in November 2025 added new dimensions to what we know about choline deficiency and the brain. A UC Davis study found that people with anxiety disorders showed approximately 8 percent lower choline levels in key brain regions, with especially consistent reductions in the prefrontal cortex — the area responsible for controlling thinking, emotions, and behavior. This does not prove that low choline causes anxiety, but it opens a line of investigation that connects a common nutrient gap to a common mental health condition. A separate study reported by ScienceDaily in November 2025 tied low choline levels to inflammation, liver strain, and neuron injury markers, particularly in young adults with obesity. The researchers noted that women had lower choline levels than men — a finding that is especially concerning because women experience higher rates of cognitive aging and Alzheimer’s disease.
Less than 9 percent of pregnant women currently meet the adequate intake for choline, which raises questions about whether choline deficiency during pregnancy could have downstream effects on both maternal and infant brain health. However, it is important not to leap from these findings to alarm. Frank choline deficiency in healthy, non-pregnant adults is rare because the body can synthesize some choline on its own, primarily in the liver. The issue for most people is not outright deficiency but chronic suboptimal intake — getting enough to avoid obvious symptoms but not enough to support long-term brain health. That distinction matters, because it means the fix is usually dietary adjustment, not emergency intervention.
The Top Choline-Rich Foods Ranked by Milligrams Per Serving
Organ meats dominate the top of the choline chart, and there is no getting around that. Beef liver leads at 356 mg per three-ounce serving, followed by chicken liver at 247 mg. For people who find liver palatable, even one serving per week makes a significant dent in the weekly choline goal. Pâté, liverwurst, or liver blended into meatloaf or bolognese sauce are ways people manage the flavor without eating straight organ meat. For those who will never willingly eat liver, the next tier is still effective. Salmon provides 187 mg per three ounces, and a single large egg delivers 147 mg — nearly all of it in the yolk, which is why egg-white-only diets strip out one of the most concentrated choline sources available.
Black beans come in at 129 mg per cup, shiitake mushrooms at 116 mg per cooked cup, and roasted soybeans at 107 mg per half cup. Lean flank steak offers about 100 mg per four ounces, and dark meat chicken provides 85 mg per four ounces. Even canned pink salmon at 75 mg per three ounces and Atlantic cod at 72 mg contribute meaningfully. A realistic example: two eggs for breakfast (294 mg), a cup of black beans with lunch (129 mg), and four ounces of chicken thigh at dinner (85 mg) gets you to 508 mg — within range for most adults. That is not a restrictive or unusual day of eating. It just requires choosing choline-dense foods intentionally rather than defaulting to grains and vegetables, which tend to be low in this nutrient.
How to Build Choline Into Your Diet Without a Complete Overhaul
The simplest, highest-impact change most people can make is to eat whole eggs regularly. Two eggs several mornings a week adds roughly 294 mg of choline each time, and eggs are cheap, fast to prepare, and widely available. For years, dietary guidelines discouraged egg consumption over cholesterol concerns, and while those warnings have largely been walked back, the habit of avoiding eggs or eating only whites persists in many households. If you tolerate eggs and your doctor has not specifically restricted them, they are the single easiest choline upgrade. The tradeoff between animal and plant sources is worth understanding. Animal foods — liver, eggs, fish, poultry, and beef — deliver choline in higher concentrations per serving and in forms (phosphatidylcholine) that the body absorbs efficiently.
Plant sources like beans, soybeans, and shiitake mushrooms provide meaningful amounts but require larger servings to match. A vegetarian aiming for 425 mg per day can get there, but it takes more planning: two eggs (294 mg), a cup of cooked shiitakes (116 mg), and a half cup of roasted soybeans (107 mg) would total 517 mg. A vegan who excludes eggs faces a harder path and may need to rely heavily on soybeans, quinoa, cruciferous vegetables, and potentially a supplement to close the gap. For caregivers managing meals for someone with cognitive concerns, the practical takeaway is to anchor the diet around eggs, fish, and legumes. These foods are also generally well tolerated by older adults, easy to prepare in soft or modified textures, and compatible with most dietary restrictions. You do not need to count milligrams obsessively — just make sure choline-rich foods appear at most meals rather than occasionally.
Why Choline Supplements Are Not a Substitute for Dietary Choline
This is where the research delivers a sobering reality check. While choline-rich diets are consistently associated with better cognition in observational studies, choline supplements have not been shown to improve cognition in healthy adults or in patients with Alzheimer’s, Parkinson’s dementia, or other memory disorders, according to the NIH Office of Dietary Supplements. That is a critical distinction. The studies that show benefits are tracking people who eat choline-rich foods over years or decades — not people who start popping choline capsules after a diagnosis. There is one notable exception worth mentioning carefully. A study published in Frontiers in Aging Neuroscience in 2025 examined choline alphoscerate, a specific pharmaceutical form of choline used in some European countries, in patients with mild cognitive impairment.
After three years, progression of cognitive deficits was 12.2 percent in the choline alphoscerate group compared to 39.1 percent without it, and conversion to Alzheimer’s was 8.2 percent versus 26.1 percent. Those numbers are striking, but choline alphoscerate is not the same as the choline bitartrate or phosphatidylcholine sold in most supplement aisles. Extrapolating from one pharmaceutical compound to over-the-counter supplements would be a mistake. The tolerable upper intake level for choline in adults is 3,500 mg per day, so toxicity from food alone is essentially impossible. But high-dose supplements can cause fishy body odor, sweating, gastrointestinal distress, and in some cases, may increase trimethylamine N-oxide (TMAO) levels, which have been linked to cardiovascular risk. The safest and best-supported approach remains getting choline from food, where it comes packaged with other nutrients and in forms the body handles well.
Choline Needs During Pregnancy and Why the Gap Is Alarming
The choline shortfall is most concerning in pregnant women, where the adequate intake rises to 450 mg per day and fewer than 9 percent currently meet that target. Choline is critical for fetal brain development, particularly in the formation of the hippocampus — the memory center of the brain. Prenatal vitamins, surprisingly, often contain little or no choline. A woman taking a standard prenatal supplement and eating a typical American diet may be getting less than half the choline her developing baby needs.
This matters for dementia prevention in a broader sense than most people realize. Brain health does not begin at age 65. The structural foundations laid during fetal development and early childhood influence cognitive reserve decades later. Encouraging adequate choline intake during pregnancy is not just an obstetric concern — it is arguably one of the earliest possible interventions for long-term brain health.
Where Choline Research Is Heading
The 2024 and 2025 studies signal a growing scientific interest in choline that extends beyond its traditional role in liver health. The UC Davis findings linking choline levels to anxiety disorders, the obesity-inflammation connection, and the long-term Chinese cohort data all suggest that choline’s role in brain health is broader and more nuanced than the simple acetylcholine production story. Researchers are now investigating whether choline status in midlife could serve as a modifiable risk factor for dementia — meaning something you can actually change, unlike age or genetics.
For families dealing with dementia or watching a parent’s memory slip, this research offers a grounded, non-sensational reason to pay attention to diet. Choline is not a cure for Alzheimer’s. No nutrient is. But the accumulating evidence suggests that decades of inadequate choline intake may quietly erode the brain’s structural and chemical resilience, and that closing the gap through food is one of the simpler, lower-risk steps available.
Conclusion
Choline is one of the most under-consumed nutrients in the American diet, and its connection to brain health — through acetylcholine production, memory performance, and structural brain markers — is supported by decades of research and reinforced by studies as recent as late 2025. The best food sources are beef liver, eggs, salmon, beans, and shiitake mushrooms, and reaching the daily adequate intake of 425 to 550 mg is achievable without dramatic dietary changes. Two eggs and a serving of fish or legumes at another meal will get most people close to the target.
The most important next step is also the simplest: look at what you ate yesterday and count the choline-rich foods. If you cannot name more than one, that is the gap. Supplements have not proven effective for cognition, but food-based choline, consumed consistently over years, aligns with better outcomes in every major study to date. For caregivers, building meals around eggs, fish, and beans is a practical, evidence-based strategy that supports the brain without requiring a nutritionist’s guidance or a specialized diet plan.
Frequently Asked Questions
How much choline do I need per day?
Adult men need 550 mg per day and adult women need 425 mg per day, according to the NIH. Pregnant women need 450 mg, and breastfeeding women need 550 mg. These are adequate intake levels, not minimums — meaning most people should aim for at least these amounts.
What single food has the most choline?
Beef liver, with 356 mg per three-ounce serving. If organ meat is not appealing, one large egg provides 147 mg, making eggs the most practical high-choline food for daily consumption.
Can choline supplements prevent Alzheimer’s disease?
Current evidence says no. The NIH states that choline supplements have not been shown to improve cognition in patients with Alzheimer’s or other memory disorders. However, one 2025 study found that choline alphoscerate, a specific pharmaceutical form not widely available as a supplement, was associated with slower cognitive decline in MCI patients. Dietary choline from food remains the best-supported approach.
Is choline the same as phosphatidylcholine or lecithin?
They are related but not identical. Phosphatidylcholine is a form of choline found in foods like eggs and soybeans, and lecithin supplements contain phosphatidylcholine. However, the amount of actual choline in lecithin supplements varies widely, and the body processes these forms differently than choline obtained directly from whole foods.
Do vegetarians and vegans get enough choline?
It is possible but requires deliberate planning. Eggs are one of the best sources, so lacto-ovo vegetarians have an advantage. Vegans can get choline from soybeans, quinoa, beans, shiitake mushrooms, and cruciferous vegetables, but may need to eat larger quantities. Consulting a dietitian and considering a choline supplement may be prudent for strict vegans.
Can you get too much choline from food?
It is virtually impossible to exceed the tolerable upper intake of 3,500 mg per day through food alone. Overconsumption is only a realistic concern with high-dose supplements, which can cause gastrointestinal symptoms and fishy body odor.
