What the Evidence Shows

We analyzed the available evidence and found that eating one to three eggs a day for a month is associated with an increase in choline levels in healthy adults. The evidence we’ve reviewed so far shows that higher egg intake leads to higher choline levels, but not to levels that appear harmful [1]. No studies in our review contradicted this pattern.

Choline is a nutrient your body needs to support brain function, liver health, and cell structure. Eggs are one of the richest food sources of choline, and the data we’ve seen suggest that consuming them regularly can help raise your body’s choline supply in a gradual, steady way. The increase appears to be dose-related — meaning more eggs generally lead to higher levels — but within the range studied, there was no sign of excessive buildup that would raise concern.

We did not find any evidence suggesting that this increase is unsafe or harmful for healthy adults. However, our analysis is limited to the specific range of one to three eggs per day over a one-month period. We don’t have data on longer-term intake, very high daily consumption, or individuals with pre-existing health conditions.

What we’ve found so far leans toward eggs being a reliable dietary source of choline for healthy adults who eat them regularly. If you’re looking to support your choline levels through food, including eggs in your meals appears to be a practical approach based on the current evidence.

Evidence from Studies

Supporting (1)

In young, healthy adults, daily consumption of one to three eggs for four weeks is associated with a dose-dependent increase in plasma choline levels, rising significantly above baseline without exceeding normal physiological ranges, indicating that egg intake effectively elevates this essential nutrient without inducing toxicity.
