Meet Dr. Nihan Marun...
I became a veterinarian because I believed I can help animals better. Then I became a microbiologist because I discovered that microorganisms are the way we can provide health... if we learn how to manage them.
Finally, I became an entrepreneur because I realized the gap between what science knows, what the industry does, and what the doctors, technicians, and nurses learn was too wide.
My journey started in Turkey, where I earned my DVM in 2006 and my PhD in Microbiology in 2012. But the real education began the day I stepped out of the lab and into the global biotics industry. For the past 15+ years, I've worked as an independent expert across Asia, Europe, Eurasia, North America, and South America. I helped companies build, formulate, manufacture, register, and launch probiotic products. From strain selection in the lab to million-dollar deals in the boardroom. From writing regulatory dossiers at midnight to presenting my field trial results at international conferences the next morning.

I've launched products, consulted for Fortune 500 companies, completed 150+ projects, and produced over 1,000 scientific and technical documents. I've taught at universities, reviewed scientific articles for Frontiers in Microbiology, published books, and built teams of experts across continents. Today, I am a doctor of veterinarian for 20 years and I am also a mother of three precious little human beings. I had the opportunity to raise them with a love of science and a heart for animals and earth.
But... after all those years of reading the science, testing in the labs, teaching microbiology and traveling the world to help probiotics companies and brands, I still see a serious gap. I remember 2012, when I started asking "Do you know about probiotics?" to every pharmacist, doctor, and nurse I met. The answer was "No" from over 85–90% of them. Today, we are living the early golden age of microbiome and biotic science, and the answers have turned into "Yes" for over 85–90%. Yet most veterinarians, let alone pet owners, still don't have the information they need about the microbiome, probiotics, and antimicrobial resistance.
​
This tells me one thing clearly... We've had the knowledge for a long time. What's been missing is the translation of science into life. Ad today, that's why Sigma BioVet Sciences exists.
​
With warmest respects,

The Responsible Biotics Framework™
After two decades of working across the science, industry, and consumer sides of microbiome and biotics globally, I built this framework as a methodology that takes science from microbiome to market.
​It's how I evaluate every product and project I receive.
And this framework is the guarantee of the best results for every claim that crosses my desk.


Clean science. Clean manufacturing. Clean product.
Clean label. Clean advice.
Clean results until the end of shelf life.
​​When a microbiologist uses the word 'clean,' she means
honest, trusted, and accountable.
