In an earlier blog post on vitamin B12 for older adults, I wrote that “vitamin B12 is poorly absorbed from eggs.” Thanks to a reader who pointed out that a recent study found that vitamin B12 absorption from eggs is higher than was previously thought. This study used a different method to examine vitamin B12 absorption than has been used in the past. Despite this finding, it’s still recommended that those 51 and older use vitamin B12-fortified foods or a vitamin B12 supplement to meet most of their vitamin B12 requirement rather than relying on eggs or other foods with naturally occurring vitamin B12.
