Science Meets Human Health.
For more than two decades, Kiran Krishnan has been one of the most trusted educators and innovators in microbiome science. His work bridges the worlds of clinical research, product development, and real-world education — all with one goal: to help people understand their bodies so they can transform their health.
A Life Shaped by Curiosity — and Microbes.
If you’ve ever wondered what happens when a research microbiologist, entrepreneur, and lifelong science geek decides to devote his entire career to gut bacteria… you’re looking at it.
Kiran was born in India and raised between India and Malaysia before moving to the United States in junior high. His mother — a talented physician — inspired his fascination with biology and the human body. His father — a microelectronics engineer with more than 200 patents — shaped his love for systems, innovation, and how things fit together.
It was the perfect recipe.
A blend of petri dishes and patents.
That combination led him straight into microbiology at the University of Iowa, where he discovered what would become the focus of his life’s work:
The most powerful ecosystem we will ever study is the one living inside us — our microbiome.
From Research
to Real-World Impact.
Since graduating, Kiran has spent his career exploring and explaining the invisible world that shapes human health.
Designed and conducted more than 50 human clinical trials.
Published research in peer-reviewed scientific journals.
Contributed chapters to medical textbooks and functional medicine references.
Presented at dozens of international medical conferences.
Educated millions through lectures, trainings, interviews, and digital programs.
Along the way, he co-founded several influential companies, including:
EST 2014
The company that introduced spore-based probiotics to clinicians and helped revolutionize the microbiome space.
EST 2020
EndoAxis is an advanced analytical engine powered by an innovative algorithm designed to simplify DUTCH® test analysis and deliver clear, actionable insights. By translating complex hormone data into clear patterns and targeted therapeutic guidance, we empower providers to deliver confident, precise hormone care.
EST 2023
SIV™ helps people achieve healthy, resilient skin through biome-balancing skincare that works in harmony with the skin’s natural ecosystem. Using quorum sensing technology, we support skin homeostasis by balancing the unique skin biome – harnessing your biology for resilient skin through a truly personal, biology-first approach.
A global educator with a practical mission.
Kiran’s work sits at the intersection of gut health, immune balance, metabolism, hormones, and the chronic conditions that arise when these systems fall out of sync.
His gift is translating complex scientific mechanisms into explanations that are clear, accessible, engaging, and actually useful — whether he’s speaking to a doctor, a coach, or someone who just wants to feel better.
And yes, he’ll also spend an impressive amount of time convincing you that bile acids are fascinating. (He’s not wrong.)
Beyond the Lab
When Kiran isn’t analyzing data or speaking on stage, you’ll likely find him outside on his bike. A former competitive cyclist, he still loves the kind of long rides that make your legs burn and your mind go quiet.
He’s also a devoted foodie who believes you can learn as much about a culture from its cuisine as from its science. With more than 3.5 million miles flown, he has eaten his way through kitchens and markets all over the world.
His personal philosophy?
Be so metabolically resilient that you can make 20% “bad decisions” and still be healthy. Enjoy the dessert. Have the drink. Live your life.
The goal is adaptability — not perfection.
The Birth of the Biome Learning Center.
After decades of teaching, researching, and developing products, Kiran saw a need:
People were hungry for microbiome education that was scientifically rigorous, practical, and easy to understand — all in one place. The Biome Learning Center was born from that vision.
It is the culmination of his life’s work… a home for courses, trainings, tools, community, and research-driven insights designed to help both individuals and practitioners build true, lasting resilience from the inside out.
A Simple Mission, A Big Impact.
At the core of everything Kiran does is this belief: KNOWLEDGE IS POWER.
It helps them ask better questions, make better decisions, advocate for their health, and understand their bodies with confidence rather than fear.
