FOUNDATIONAL NUTRITION MADE FOR YOU
About IBS Dietitians
At IBS Dietitians, we do things differently — because IBS needs more than symptom management. It needs a strategy.
Table of Contents
ToggleFounded by a registered dietitian with a deep understanding of what truly drives gut dysfunction, this practice goes beyond the basics to deliver a cellular-first, science-forward approach to lasting relief. We specialize in helping people with IBS feel significantly better — not just for a few days, but for good.
Our method is built on what most programs miss:
Cellular energy reboot – because healing starts where your health begins: in your cells
Nerve tune-ups – to calm the gut-brain communication that's often misfiring
Friendly-flora reset – restoring microbial harmony in a way that lasts
Movement restoration – reactivating natural motility so digestion works as it should
We don’t do quick fixes. We do clear frameworks that restore function and build real resilience.
At IBS Dietitians, getting better isn’t a mystery — it’s a method.
About Marina, Founder & Owner
Hi, I’m Marina Bedrossian — a registered dietitian nutritionist and the founder of IBS Dietitians.
After years of seeing people struggle with frustrating symptoms and dead-end diets, I knew there had to be a better way. That’s why I created a practice that doesn’t just chase symptoms — it addresses the deeper dysfunctions keeping people stuck.
I focus on what really moves the needle: cellular health, nervous system balance, and restoring natural gut function. My mission is simple — to help you finally feel like yourself again.
I am a horse-obsessed, Brazilian jiu-jitsu-ninja, nature enthusiast, health-nut, homeschooling teacher, and freedom-lover who is divinely guided to live my best life and help others do the same.
