Marina E. De León, CNC, PhD

Gut Microbiome Specialist

I am a Doctor of Microbiology and a Certified Nutritionist

The gut microbiome is emerging as a foundation of human health, influencing physiology, resilience, mental health, and disease risk

My practice uses this science and evidence-based foundation along with a whole foods diet to maximize your total health, personalized to you

The gut, often referred to as our "second brain," plays a pivotal role in shaping our health outcomes.

My approach is not just about isolated dietary changes, it's a holistic transformation that encompasses your unique needs, food preferences, and lifestyle. However, in general there are rules that no one can escape.

Perspective and lifestyle play integral roles in a microbiome-based nutrition plan for improved health.

About me and my practice

I have a Ph.D. in Microbiology from The University of California, Davis and a C.N.C from Bauman College, Berkeley, CA.

My clients typically suffer from gastrointenstinal diseases, such as diarrhea, constipation, IBS, SIBO and other general digestive health concerns.

My speciality is doing the individualized scientific analysis on a client per client basis finding root causes often eluded by their general practioners and specialists.

I analyze heath and bio markers using clinical labs such as, Genova, GI-Map, NirvanaBiome, Viome, Zoe, among others, to identify root issues stemming from your gut and bacterial health.

With these findings, I provide regimens consisting of a combination of supplements, dietary and lifestyle changes.

Clients typically see improvements within the first week or two. We can continue to work together until you feel your digestive health is not negatively impacting your life.

In addition to my private practice, I also partner with Elevétion and Flore. Feel free to read their websites and let me know if you’d like to learn more about them.
