If three or more of these ring true, your gut is trying to tell you something specific.
You don't need another probiotic. You need a plan that finds out what's actually going on.
Most adult gut symptoms aren't random. They're driven by a small handful of identifiable triggers, mediated by your gut microbiome and the nervous system that runs through your gut wall.
The biggest single driver: FODMAPs. These are fermentable carbohydrates found in everyday foods like onion, garlic, wheat, apple, dairy and many legumes. When your gut can't process them, they ferment in the small intestine. 70–75% of people with persistent bloating have a FODMAP component (Halmos et al., Gastroenterology, 2014).
The second driver: an imbalanced microbiome. Ultra-processed food, frequent antibiotics, and chronic stress disrupt the gut bacteria; real food, fibre and fermented foods support them.
The third: the gut-brain axis. An unhappy gut sends signals that show up as anxiety, brain fog, mood swings.
Two programs, one approach. The 21-Day Gut Reset is the diagnostic phase — built on Monash University's low-FODMAP framework. The 8-Week Program locks in the long-term pattern.
70–75% relief for people with persistent bloating on a structured low-FODMAP protocol.
(Halmos et al., Gastroenterology, 2014)Protocol reviewed by the IQS science team and expert panel.
The Monash-framework protocol. Strip the most common triggers, reintroduce systematically, build your personal map. You leave knowing exactly what works.
Once you know your baseline, the 8-Week Program is the long-term pattern. Real food, microbiome-supportive eating, structured to lock in the gut you've built.
Diagnose first. Sustain second. No more guessing. No more fear lists.
Not necessarily. If your main issue is bloating + figuring out triggers, the 21-Day Gut Reset alone may be enough. Many members do both.
The app is great for elimination, but doesn't structure the reintroduction. Many people going it alone get stuck in Phase 1 for far too long. The Gut Reset takes you through all three phases.
For IBS, generally yes — many members have IBS and the protocol is designed with sensitive guts in mind. For diagnosed IBD (Crohn's, ulcerative colitis), please talk to your gastroenterologist first.
No. The plan is built around full meals. The point isn't to eat less. It's to find out what your gut can't handle.
The gut-brain connection is real and well documented. Some members tell us their energy and focus improved alongside their digestion. Outcomes vary.
Pregnant: no — Phase 1 is too restrictive. Breastfeeding: we don't recommend. Talk to your GP.
Vegetarian fully. Vegan mostly — Phase 1 is harder vegan due to legume restrictions but we provide adapted recipes.
