Erratum to: Eur J Nutr DOI 10.1007/s00394-016-1221-1

In the original publication of the article, serum vitamin B12 must be placed instead of plasma vitamin B12 throughout the manuscript. This mistake does not interfere either in the results or in the interpretation of the manuscript. Even if the original name of ‘plasma vitamin B12’ is not specifically bad worded (as serum is included in the plasma), it is much precise to use ‘serum vitamin B12’ as this is the term used in other HELENA study-based manuscripts.
