This week on Startup to Storefront, we're thrilled to welcome Dr. Will Bulsiewicz, better known as Dr. B, a world-renowned gastroenterologist, bestselling author, and founder of 38TERA, a company revolutionizing the gut health space. Dr. B has built his career around one core idea: that the key to unlocking better energy, stronger immunity, and even better mental health starts with your gut. His books, Fiber Fueled and The Fiber Fueled Cookbook, became instant bestsellers, and his mission to teach the world about the microbiome has reached thousands through platforms like Diary of a CEO and The Rich Roll Podcast. In today's episode, Dr. B shares his journey from frustrated physician to founder, launching DMN — Daily Microbiome Nutrition — to finally offer a gut supplement he could stand behind. We also dive into the outrageous diet myths flooding TikTok, the real impact of gut health on your everyday life, and why it might just be the key to unlocking your full potential.

On this week's episode you'll learn:

✨ How to transform your gut health (and your life)
