The article "Performance improvement in sport through vitamin D - a narrative review" by K. Weiss, A. Devrim-Lanpir, Z. Jastrzębski, P.T. Nikolaidis, L. Hill, B. Knechtle, published Eur Rev Med Pharmacol Sci 2022; 26 (21): 7756-7770-DOI: 10.26355/eurrev_202211_30124-PMID: 36394723 has been retracted by the Editor in Chief. This decision follows concerns of potential plagiarism with the following article "Plausible ergogenic effects of vitamin D on athletic performance and recovery", raised by third parties, prompting the journal to conduct an investigation. The investigation determined that, although the original manuscript was cited in the references (ref. 23), the paraphrasing was excessively similar to the original text, constituting plagiarism. The authors were notified of the investigation but were unable to provide a satisfactory explanation to address these concerns. Consequently, the Editor in Chief has decided to retract the article. The authors have been informed about this retraction. This article has been retracted. The Publisher apologizes for any inconvenience this may cause. https://www.europeanreview.org/article/30124.
