Address the miscommunication between your gut and brain. Designed for people living with IBS, functional dyspepsia (FD), GERD, bloating symptoms, and other gut–brain disorders - as well as those seeking additional support alongside IBD care - Nerva is a personalized gut–brain program that supports symptom management through daily sessions, practical tools, and structured guidance. Target the root cause Many people spend years cutting out foods in an effort to calm their gut - a difficult path that can miss what’s really driving symptoms. In disorders of gut–brain interaction (DGBIs), the root cause is gut–brain hypersensitivity. After a trigger like illness, antibiotics, or prolonged stress, the nerves in the gut can become over-reactive. Even once the gut tissue heals, the nervous system may keep the alarm turned up. Normal digestion, gas, or movement are then misread as danger - leading to pain, bloating, reflux, urgency, constipation, or diarrhea. Diets and medications can reduce symptoms temporarily, but they don’t retrain this signaling system. That’s why symptoms often return or shift over time. Lasting relief means calming the nervous system and restoring healthy gut–brain communication - where the symptoms actually start. How Nerva helps Nerva is a structured gut–brain program that helps you practice brain-gut techniques shown to support a calmer response to gut sensations. Over the program you'll learn to: - Respond differently to uncomfortable gut signals - Practice calming the gut–brain stress response - Build daily habits that support digestive comfort Tailored to you No two guts are the same. Nerva adapts your program to your symptoms, triggers, and progress - using AI to adjust the coaching and guidance as you go. The sessions, the tools you receive, and the coaching you follow are all shaped around your experience. Evidence-based Unlike most apps, Nerva is built on clinical research. In a randomized controlled trial at Monash University, Nerva helped 81% of people significantly manage their gastrointestinal symptoms. Since then, more than 300,000 people have used Nerva, and over 11,000 healthcare providers recommend it. Features of Nerva - Daily 15-minute sessions designed to retrain gut-brain miscommunication - Flare-up tools for pain, bloating, constipation, reflux and diarrhea - Long-term maintenance plan to keep symptoms under control after the program - AI personalization to tailor the program to your selected triggers and progress Who is the team behind Nerva? Nerva was built by Dr. Simone Peters, GI psychophysiologist, together with clinicians, dietitians, and researchers. Many of us live with gut conditions ourselves.

Many world-renowned Doctors and specialists recommend the program to their patients: Dr. Neil Nathan MD - Global Renowned Expert in Mold Illness, Founding Diplomate of the American Board of Integrative and Holistic Medicine "The majority of patients that I treat with chronic infections, such as Lyme disease, and chronic environmental toxicity, like mold, develop severe limbic dysfunction. I have found Ashok Gupta's program to be of great benefit in helping these patients to heal. In fact, when patients have become unusually sensitive or reactive, it is mandatory that they start with limbic retraining or they are not likely to make much progress. Hundreds of my patients have reported marked benefits from Ashok’s materials and I strongly encourage their use." Evan Brand, CFMP, FNTP - Functional Medicine Expert, Podcast Host and Author "As a Functional Medicine Practitioner, I've suffered my own series of health challenges. The Gupta Program has been the neuroplasticity piece that was missing from my personal and clinical protocols. I'm recommending literally almost every client we have to take the Gupta Program, especially since I've already seen progress in myself using the course. Change is possible!" Beth O'Hara, Doctorate in Naturopathy - Specializing in Functional Naturopathy, Mast Cell Activation (MCAS) and Histamine Specialist "At Mast Cell 360, the Gupta Program is a part of our core program for those with complex, chronic Mast Cell Activation Syndrome, Histamine Intolerance, Mold Toxicity, and related conditions. It was such a game-changer for our clients, we made it one of the first steps for anyone starting the Mast Cell 360 program. Thank you for offering this amazing program for those who are suffering to help them get their health and lives back!! It is truly a service to the world." Dr. Michael Ruscio DNM, DC Functional Medicine Expert The Austin Center for Functional Medicine “The Gupta Program is one of a kind, helping patients improve their health in a variety of ways and addressing a multitude of ailments.” Dr. Lauryn Lax, OTR, NTP Doctor of Occupational Therapy, Nutritionist, & Functional Medicine. Author. “This program works! The limbic system-immune connection is an often overlooked link in the chronic illness puzzle and a huge game changer in helping patients bust through the ceilings they are hitting in their health.

It acknowledges all areas of health (physical, mental, emotional, spiritual) so you leave no stones unturned in getting to the root causes of your greatest health challenges."
