A Slovak pharmacist and scientist, Karin Marček, is using her Instagram profile, karin_science, to combat widespread health misinformation. Instagram is a popular source of advice, but often contains conflicting, unscientific, or promotional content for ineffective products. Marček focuses on debunking popular myths in pharmacy, science, and medicine. She addresses trends gaining traction on social media that lack a scientific basis, warning users against potentially harmful or wasteful practices. The core issue is the prevalence of disproven advice alongside promotion of expensive, unnecessary items. Marček’s work aims to provide evidence-based information to counter this problem. Her platform strives to offer reliable guidance within the often-chaotic landscape of online health advice.
