When you eat eggs, your body doesn’t absorb much of the vitamin B12 inside them—less than 9%—so they’re not a great way to get this vitamin compared to other animal foods like meat or fish.

Vitamin B12 Sources and Bioavailability

Narrative Review

2007 Nov

The study found that your body can barely absorb the vitamin B12 from eggs—less than 9%—while it absorbs much more from meat and fish, so eggs are a much weaker source of this vitamin.

Similar Assertions

When you eat fish, sheep meat, or chicken, your body absorbs vitamin B12 from them at different rates—fish gives you about 42% of the B12, sheep meat gives you 56% to 89%, and chicken gives you 61% to 66%, so not all meats give you the same amount of this important vitamin.
