“Balancing the autonomic nervous system plays a crucial role in gut health. With Yona, I’ve found improvement in many issues like bloating, constipation, diarrhoea and gut-related inflammation.”
Where it fits
Most gut products start with bacteria. Yona works in two layers.
Your gut doesn’t run on its own. The nervous system tells it when to move, digest and settle, mostly through the vagus nerve. Vagus One supports that signal.
Gut Repair+ is the second layer: direct support for the gut environment the signal arrives at, starting with the lining.
New to Yona? We usually recommend starting with Vagus One and adding Gut Repair+ when you want more direct gut support. See Vagus One
Layer 1 · Vagus One
The signal
Nutrients for normal nervous system function and the gut–brain connection. The upstream half of the system.
Layer 2 · Gut Repair+
The environment
Four ingredients for the gut lining, the mucus layer above it and the balance of what lives in your gut.
How it works
Your gut lining is one cell thick.
That single layer of cells is the boundary between what you eat and the rest of you, and your body replaces it every few days. Gut Repair+ puts four ingredients to work on it, each on a different part.
2250 mg
Saccharomyces boulardii
A beneficial yeast
Not a bacterial probiotic. A well-studied yeast that supports a balanced gut microbiome and a healthier gut environment.
375 mg
Zinc L-Carnosine
Protection for the lining
Zinc bound to carnosine, a form known for adhering to the gut lining, where it supports the mucosa and the joins between cells. Zinc contributes to the normal function of the immune system.
41,000 mg
Serum-Derived Bovine Immunoglobulin
Binds what shouldn’t be there
Concentrated IgG proteins that bind bacteria, toxins and other unwanted substances inside the gut, before they reach the lining.

Full transparency
Four ingredients. Nothing hidden.
Butyrate, S. boulardii, zinc carnosine and immunoglobulins, each chosen for the gut lining.
What’s not in it

- Not suitable for vegans or vegetarians: contains bovine-derived immunoglobulin

The difference
Why not just take a probiotic?
Probiotics add bacteria. Cleanses try to clear things out. Gut Repair+ supports the lining those bacteria live against.
| Gut Repair+ | Typical probiotic | Herbal gut cleanse | |
|---|---|---|---|
| Works on the gut lining itself | Yes | Not the focus | No |
| Fuel for lining cells (butyrate) | 500 mg | No | No |
| Beneficial microbe | S. boulardii (yeast) | Bacterial strains | No |
| Gentle on sensitive systems | No harsh herbs | Varies | Often strong antimicrobial herbs |
| Built to pair with nervous-system support | Vagus One | No | No |
Honest fit
Is Gut Repair+ right for you?
It’s a good fit if you…
- Already take Vagus One and want more gut-focused support
- Want something broader than a probiotic on its own
- Prefer a gentle approach without harsh herbal blends

It’s probably not for you if you…

- Expect a supplement to replace medical advice or treatment
Your first 12 weeks
Built for consistency, not a quick fix.
The lining renews itself continuously, so steady daily support matters more than any single dose. Here’s what the routine looks like.
Week 1
Start gently
Take with or without food. If your system is sensitive, begin with 1–2 capsules and build up to 3 a day.
Weeks 2–4
Build consistency
Same time, every day, alongside Vagus One. Consistency is what the routine runs on.
Weeks 5–8
Support the environment
Keep going. This is where daily support for the lining and gut balance adds up.
Weeks 9–12
Continue your routine
Finish the full 12 weeks, then decide whether to keep it as ongoing support.
3 bottles cover the full routine at £36.00 a bottle, which works out to £1.20 a day.

Chat on WhatsAppHow is Gut Repair+ different from Vagus One?
Vagus One is the foundation of the Yona system. It supports the nervous system and the gut–brain connection, the upstream signal.
Gut Repair+ works more directly on the gut environment itself: the lining, the mucus layer and the balance of what lives in your gut.
Do I need both?
Not always. If you’re new to Yona, we usually recommend starting with Vagus One. Gut Repair+ is best for people who want additional, direct gut support alongside it.
Is Gut Repair+ a probiotic?
No, it isn’t a standard probiotic. It contains Saccharomyces boulardii, a beneficial yeast, alongside sodium butyrate, zinc L-carnosine and serum-derived bovine immunoglobulin.
How do I take it, and how long does a bottle last?
Take 3 capsules a day, with or without food. Each bottle holds 90 capsules, which is 30 days. If your system is sensitive, start with 1–2 capsules and build up gradually.
When should I expect to notice a difference?
Gut Repair+ is designed to be taken consistently as part of a 12-week routine. Support for the gut environment builds gradually, so we suggest judging it over the full 12 weeks rather than the first few days. Everyone’s experience is different.
Is it vegan or vegetarian?
No. Gut Repair+ contains serum-derived bovine immunoglobulin, so it isn’t suitable for vegans or vegetarians.
Can I take it with medication, including PPIs?
If you take medication, have a medical condition, are pregnant or breastfeeding, or are under medical supervision, speak to your doctor or pharmacist before using any supplement.
Gut Repair+ isn’t a replacement for medication. Don’t stop or change prescribed medication without medical guidance.
Where do you deliver and how long does it take?
We ship from the UK with Royal Mail or Yodel. Standard UK delivery is free and takes 2–3 working days. Express next-working-day delivery is available at checkout for orders placed before 12pm.
