Introduction: Data sharing is being increasingly required by journals and has been heralded as a solution to the 'replication crisis'.
Objectives: (i) Review data sharing policies of journals publishing the most metabolomics papers associated with open data and (ii) compare these journals' policies to those that publish the most metabolomics papers.
Methods: A PubMed search was used to identify metabolomics papers. Metabolomics data repositories were manually searched for linked publications.
Results: Journals that support data sharing are not necessarily those with the most papers associated to open metabolomics data.
Conclusion: Further efforts are required to improve data sharing in metabolomics.
Keywords: Data sharing; Journal; Metabolomics; Open data.
