title: The most widely viewed YouTube videos with content related to multivitamins.
abstract: Background:Use of multivitamin/multimineral (MVM) and other dietary supplements is common among American adults. The purpose of this study was to describe the source and content of the most widely viewed YouTube videos associated with MVM supplements.Methods:Videos were filtered by number of views and the source of the video upload was recorded. A comparison of video characteristics and differences in video content was conducted.Results:Cumulatively, the videos in this sample were viewed 25 573 055 times. The majority of videos found in this sample were uploaded by a nutrition, wellness, or fitness channels. Most videos mentioned benefits (80.4%, 95% CI: 72.5%, 88.3%) and advocated for use of the supplement (72.2%, 95% CI: 63.3%, 81.1%). Over 84% (84.5%, 95% CI: 77.3, 91.7%) of the videos did not mention risks associated with taking a particular vitamin or supplement.Conclusion:The findings of this study indicate that MVMs are often promoted and encouraged, yet risks associated with MVMs were infrequently mentioned. Health professionals should be aware of the extent to which MVM related content appears on social media and, more importantly, be attuned to the content, which can be misleading, or missing information regarding risks and/or evidence of possible benefits.
