A nutrition story that starts at a mid-century breakfast table.
The breakfast that used to be normal
Eggs, most mornings. Liver on the dinner table once a week, decades before anyone called it nose-to-tail eating. Not health food — just food, and cheap food at that.
Nobody was doing it for a nutrient. But a household eating that way was taking in a steady daily supply of choline, without ever hearing the word.
Then both foods went out of fashion
Eggs spent thirty years out of favour over dietary cholesterol. Organ meats simply disappeared from the weekly shop, pushed out by convenience and taste.
Choline went with them. And unlike the nutrients that got famous — vitamin C, calcium, iron, fibre — it was never fortified into anything, never printed on a cereal box, never given a campaign. It left the national diet quietly, without anyone noticing it had been there.
What the body was using it for
Choline is not a minor player. It goes into cell membranes and it supports liver function. And it is the raw material for acetylcholine, the neurotransmitter the brain uses for attention and memory.
That last role is the thread worth following, because choline is the one part of it a label can check.
Where intake sits now
Habitual choline intake in the United States is below the Adequate Intake.1 In a 2025 study of adults aged 65 and over, only 10% met it.2
That is a description of a population's diet, not a diagnosis of anyone in it. But it is a real shortfall in a nutrient with a real job.
Food first, honestly
If eggs are already on the table most mornings, that is the foundation this whole story argues for, and no capsule replaces a decent diet. That deserves to be said outright rather than glossed over.
The research on cognitive performance, though, used specific forms. Alpha-GPC in particular, studied in healthy adults at servings of roughly 250–630 mg.3 Which form a given pack uses is printed on the back, in one word, and that is the place to look before anything else.
