Welcome to Intrinsic Genomics
We help you understand what makes your DNA unique, and how to use that information to make smarter daily choices and feel your best.
Genomic insight, made accessible
For a long time, genomic insights were mostly available through expensive, cash-only specialty clinics. We believe this information should be accessible to everyone.
Our goal is simple: make genetics useful for real life. We translate your results into wellness recommendations, especially around food and metabolism, so you can feel better now and support healthy aging. For example, we may suggest shifting carbs earlier in the day or limiting them later in the evening if your genetics show a pattern of higher carb sensitivity.

Turning decades of data science into everyday guidance
Intrinsic Genomics was founded by Maria Marsala Herlihy, a translational genomicist with over 35 years in data science. She began her career after completing an MS in Statistics and Operations Research at NYU, grew into an Executive Data Scientist, and has spent the last seven years focused on translating genomic research into practical, everyday guidance.
In Maria’s words
I’ve personally struggled with gastrointestinal issues, migraines, body aches, and inflammation since childhood. After having children, life became so hectic that I often ate whatever was convenient, without thinking about what it was or the quality of the food. Over time, I gradually gained weight and developed the wellness issues that come with it.
As an adult, I tried to do everything “right.” I followed the food pyramid, experimented with new nutrition advice, and committed to the popular diets, trending workouts, and recommended supplements. Still, I felt exhausted, frustrated, and stuck. The problem wasn’t that those plans didn’t work for anyone — it was that they weren’t designed for my body.
For decades, I turned research into actionable decisions for executives. In 2015, I started researching genetic influences on my diet, and I was astonished by how much of the science already existed, buried in thousands of peer-reviewed studies, to explain why my body responded the way it did. Those insights changed how I ate, how I moved, and how I felt.
That realization is why I started Intrinsic Genomics in 2023. My goal wasn’t to discover new science, but to make existing science understandable, personal, and actionable, so you can use it to make better choices every day.

What we do, and what we don’t
We are not medical providers, and we do not give medical advice. We also don’t claim to discover new genetic breakthroughs.
We translate the science
We match your DNA to results from hundreds of thousands of published studies and turn what the science already shows into clear, usable insights.
We make it personal
Generic advice isn’t designed for your body. We translate your results into wellness guidance built around your own genetics.
We focus on real life
Especially around food and metabolism, we give practical recommendations you can act on, and explain the genetic “why” behind each one.
