#257 Personalized Nutrition, RNA vs DNA & The Future of Microbiome Testing | Momo Vuyisich @Viome
RNA microbiome testing reveals what DNA gut tests fundamentally miss. Your gut bacteria have 3,000+ genes each — DNA tests see zero of their actual activity. Dr. Momchilo (Momo) Vuyisich, Co-founder & CSO of Viome and former Los Alamos National Laboratory scientist, explains why RNA-based metatranscriptomics is a quantum leap over DNA sequencing for understanding your microbiome and personalizing nutrition.
Meet our guestDr. Momo Vuyisich spent 12 years at Los Alamos National Laboratory developing RNA-based technology for digitizing human biology. He co-founded Viome in 2016 with Naveen Jain, and the platform has since tested 500,000+ customers across 100+ countries. His personal journey with NEU5GC autoimmune sensitivity drove his mission to replace opinion-based nutrition with data-driven, personalized recommendations.
