Concerns have been raised regarding the prevalence of medical misinformation and the lack of professional expertise among health influencers on social media platforms like TikTok and Instagram.

Initial warnings from the Stiftung Gesundheitswissen highlighted the risks posed by ‘medfluencers’ who may be laypeople or entrepreneurs rather than trained professionals. The foundation noted that some accounts spread misinformation, such as contradictory sun protection advice, and advised users to verify identities and professional training to avoid advertising-driven content.

Subsequent research from Flinders University, analyzing 300 highly viewed posts under hashtags like #healthylifestyle and #nutrition, found that 78 percent of creators lacked relevant professional qualifications and that more than two-thirds of the shared health information was classified as ‘misleading or deceptive’. The study indicated that unqualified creators often promote restrictive dietary rules, link health to physical appearance, and promote supplements or superfoods without scientific nuance.

Further analysis noted that these patterns are associated with orthorexia nervosa, an unhealthy obsession with ‘pure’ or ‘clean’ eating. While Instagram content tended to focus on idealized muscular bodies, TikTok content often framed eating around general wellness. Additionally, research by the agency Billion Dollar Boy regarding 5,000 posts found that influencer effectiveness is tied to authenticity; excessive or scripted product recommendations were found to reduce organic view rates by up to 42% on Instagram and 19% on TikTok.
