Abstract: This cross-sectional study examines the impact of social media on dietary supplement use among young adults aged 18–35 years. Using an online survey of 200 respondents, the study investigated three dimensions: exposure to supplement-related content, attitudes toward supplement efficacy and safety promoted through social media, and behavioral intentions and actual consumption patterns. Descriptive statistics indicated high levels of exposure to supplement-related content (mean = 3.82, SD = 0.78), with 78% of respondents reporting regular exposure to advertisements and influencer promotions on platforms such as Instagram and TikTok. Attitudes toward supplements were moderately positive (mean = 3.45, SD = 0.92), suggesting that many participants view influencer endorsements as somewhat trustworthy while still expressing concerns regarding safety and scientific validity. Behavioral results indicated a notable impact (mean = 3.61, SD = 0.85), with 71% of participants reporting that they had purchased supplements based on online recommendations. The findings suggest that social media plays a major role in shaping perceptions and consumption behaviors related to dietary supplements among young adults. The study highlights the need for improved digital health literacy and stronger regulation of supplement marketing on social media platforms to ensure responsible and evidence-based supplement use.
