Gut and Vaginal Microbiome Optimization with Ara Katz

Today I'm speaking with Ara Katz, the co-founder of Seed, on the Longevity Optimization Podcast. In this episode, Ara shares her personal journey and the inspiration behind founding Seed. She emphasizes the vital role of the microbiome in human health and explains how nutrition shapes gut health from early life through adulthood. Our conversation explores what exactly constitutes a microbiome, how it develops (the “seeding” process), and why a diverse diet is essential for maintaining a healthy gut. Seed Probiotics is an innovative company dedicated to advancing microbiome science and optimizing human health through next-generation probiotics. Their flagship product, DS-01, is formulated using clinically-studied probiotic strains designed to support digestive health, immune function, and overall well-being. Seed also focuses on education around probiotics versus prebiotics and symbiotics—helping consumers understand their unique roles in gut health. The company leads research into women’s health topics such as the gut-vaginal axis and develops products that address hormonal changes across different life stages.
