Research Spotlight: Dr. Igor Koturbash

Dr. Koturbash and his team with Emulate equipment.

Our department chair is passionate about dietary supplement (DS) research. DS constitute a widely used group of products comprising vitamin, mineral, and botanical extract formulations. DS of botanical or herbal origins (HDS) comprise nearly 30% of all DS and are presented on the market either as single plant extracts or multi-extract-containing products. Despite generally safe toxicological profiles of most products currently present on the market, rising cases of liver injury caused by HDS – mostly by multi-ingredient and adulterated products – are of particular concern. Here we discuss the most prominent historical cases of HDS-induced hepatotoxicity – from Ephedra to Hydroxycut and OxyELITE Pro-NF, as well as products with suspected hepatotoxicity that are either currently on or are entering the market. We further provide discussion on overcoming the existing challenges with HDS-linked hepatotoxicity by introduction of advanced in silico, in vitro, in vivo, and microphysiological system approaches to address the matter of safety of those products before they reach the market.
