The mechanism

A loop, not a food problem

Stage 01
Fermentation starts early

Food ferments before it reaches the colon.

Stage 02
The gut wall takes damage

Constant fermentation irritates the gut wall, reducing absorption.

Stage 03
More fuel stays behind

Unabsorbed food feeds the bacteria again.

More fuel, more fermentation. The loop tightens with every meal.

H Active profile Reference baseline
Transit speed · accelerated

The gut moves contents through faster than it should. A chemical messenger in the intestinal wall speeds up contractions, which is why stools are looser and feel urgent.

SourceChojnacki C, et al. J Clin Med. 2021;10(10):2065.
Evidence: strong
Onset speed · rapid

Discomfort shows up within the first 90 minutes after eating. That timing is the clearest signal that fermentation is happening too high in the digestive tract.

SourceRezaie A, et al. Am J Gastroenterol. 2017;112(5):775-784.
Evidence: strong
Fermentation intensity · elevated

Across 50+ studies and 8,000+ participants, this fermentation profile showed up far more often in people with loose stools. Confirmed in lab research in 2024.

SourcesChen B, et al. J Gastroenterol. 2018;53(7):807-818. Villanueva-Millan MJ, et al. Dig Dis Sci. 2024;69(2):426-436.
Evidence: strong
Barrier sensitivity · elevated

Ongoing fermentation wears on the gut wall over time. This is the most common explanation for why the list of trigger foods tends to grow instead of staying fixed. The evidence here is less consistent than the other dimensions.

SourceBischoff SC, et al. BMC Gastroenterol. 2014;14:189.
Evidence: moderate
Motility disruption · moderate

Between meals, the gut runs a cleaning sweep that pushes residue forward. When that sweep weakens, the microbes that should have been cleared stay in place. Scores lower here, but matters most for whether the problem comes back.

SourcesVantrappen G, et al. J Clin Invest. 1977;59(6):1158-1166. Pimentel M, et al. Dig Dis Sci. 2002;47(12):2639-2643.

Everything in Signature Plan, plus:

  • Two calls a month with a microbiome expert from the N.E. Microbiome Institute, every month of the program
  • Direct email access in between, so a question on a Tuesday does not wait for the next call
  • Answers grounded in evidence, from researchers working at the edge of what the science currently shows and what is genuinely working
  • An expert with you for all 16 weeks who knows this type and knows what it tends to do and when
  • First access to new findings coming out of the institute

07 / MAINTAIN Free
Phase 3, from week 17

Fiber reintroduction, probiotic rotation, ongoing content.

08 / RELAPSE PROGRAM Free
A comeback is expected, not a setback

Research shows relapses are common with this type. We already know that, and we already know what works next. A six week rotation that takes a different approach from the first pass, built into the program from day one at no additional cost.

What most people have already tried
  • Eliminating foods one by one. It reduces the reaction temporarily, but the list of safe foods keeps shrinking because the underlying imbalance is still active.
  • Adding fiber or prebiotics. Standard gut health advice. But when digestion is already overwhelmed, more fiber increases the load instead of helping it.
  • Trying different probiotics. Most off-the-shelf strains are not selected for this type. Some make the same problem worse.
  • Waiting for it to resolve on its own. Without addressing what is driving the cycle, the pattern tends to persist or gradually widen over time.

Common questions
What if it does not work the first time?
The program is built expecting that. If bloating is still there near the end, the Relapse Program opens: a six week rotation, already in your account and included in what you paid. No dead end and no second program to buy.
How much should I budget for supplements?
Roughly $700 to $1,000 across 16 weeks, depending on the brands chosen. AlloBiome sells none of them, takes no commission, and earns nothing from any purchase.
What is the difference between the two options?
The program is the same in both. Expert Guidance adds two calls a month with a NEMI researcher and direct email access in between. You can move up from Signature to Expert Guidance at any point.
Can I cancel the monthly plan?
Yes, anytime before your next payment. If life gets in the way, pause instead. Pausing holds your place so you can pick up where you left off.
Why is the program 16 weeks and not faster?
Eight weeks addressing what is disrupting digestion, then eight weeks rebuilding the gut wall. Shorter programs skip the rebuilding half, which is why bloating comes back.
Can I do this alongside care from my own doctor?
That is exactly how it is meant to be used. AlloBiome is not medical advice, diagnosis, or treatment. It shows what the evidence says so you can bring a better informed conversation to your provider.
