A large egg contains roughly 140–170 mg of choline, almost all of it in the yolk.

How much choline is in eggs?

  • Per large whole egg: about 145–170 mg choline (around 25–30% of daily needs for most adults).
  • Per 100 g egg yolk: about 680 mg choline.
  • Per 100 g egg white: about 1 mg choline (essentially none compared with the yolk).

So if you eat 2 large eggs, you get roughly 300 mg choline, and 3 eggs give you close to 450–500 mg, which can cover most of the daily requirement for many people.
