LEAKYGUTCOMBO for Horses | Structured Support for Leaky Gut & Faecal Water

One of the most frustrating things about faecal water is that it often seems to improve... and then return.

Owners frequently tell us the same story. They change something, see an improvement for a few weeks, then suddenly they're back where they started.

Which raises the question - if the problem was simply the droppings themselves, why does it keep coming back?

The answer lies deeper within the hindgut.

The hindgut isn't just where fibre is fermented. It's home to a vast microbial ecosystem that helps regulate digestion, immune function, nutrient production, and many of the processes that keep a horse feeling comfortable and well.

When that ecosystem becomes disrupted - a state often referred to as dysbiosis , fermentation patterns begin to change. Gas production can increase, the intestinal lining comes under pressure, and the gut may struggle to regulate water movement effectively.

Over time, a long-standing state of dysbiosis can place increasing pressure on the gut lining itself. This is where "leaky gut" begins to enter the picture, contributing to the familiar patterns owners recognise as faecal water syndrome, hindgut sensitivity, bloating, inconsistent droppings, and recurring digestive instability.

And here's the challenge - it's not just about needing microbial support - it's also about rebuilding the gut lining itself.

Because once the intestinal barrier becomes compromised, simply addressing the microbes may not be enough. The gut often needs help rebuilding integrity as well.

That's why LeakyGutCOMBO takes a layered approach.

Rather than focusing on a single symptom, it combines microbial stabilisation, intestinal nourishment, and immune support into one structured programme designed to help the gut become more settled and resilient over time.

In short?

When faecal water keeps returning, the goal isn't simply to manage the symptom.

It's to support the environment that allowed the symptom to develop in the first place.

NB. Equally, human health studies now show that the microbiome as a whole rarely recovers from an 'antibiotic' impact. A botanical approach is less aggressive and has also been shown to be as effective as pharmaceutical antibiotics in clinical trials for SIBO treatment.

LeakyGutCOMBO is a good fit when your horse's gut issues have moved beyond a dysbiosis-type imbalance:

✔ Persistent faecal water that keeps returning

✔ Gas, bloating, or ongoing hindgut sensitivity

✔ Right-hand-side discomfort or reactivity around the flank area

✔ A history of stress, antibiotics, dietary disruption, or recurring hindgut imbalance

✔ You're finding yourself thinking, "the gut never seems to fully settle"

In short: if your horse appears to need both microbial support and gut-lining support at the same time, LeakyGutCOMBO is where we start.

Rather than addressing one aspect of gut health in isolation, it combines microbial stabilisation and intestinal-lining support into a single, convenient blend.

From there, support can be adapted depending on what you're seeing.

- Supporting the earlier stages

• SiboCARE – where microbial imbalance, gas, bloating, or hindgut instability appear to be the primary drivers.
• GutAminos – where the focus shifts specifically towards nourishing and supporting the intestinal lining.

LeakyGutCOMBO brings both approaches together when the distinction is no longer quite so clear.

- When a more structured approach is needed

• Hindgut Reset Programme – for horses needing a step-by-step pathway that combines comfort support, microbial rebalancing, intestinal support, and wider recovery support.

- Looking beyond the gut

Sometimes persistent faecal water sits alongside the KPU syndrome:

• KPUCOMBO – where digestive issues appear to be part of a broader systems-wide picture.
• KPU Reset Programme – where a deeper, whole-horse approach becomes appropriate.

- Foundation support

Long-term gut resilience relies on more than targeted supplements alone. Supporting your horse's baseline nutrition with a forage-based mineral foundation such as VitaComplete or EquiVita, alongside plenty of fibre and quality forage, helps create the conditions that beneficial gut microbes and healthy intestinal tissues depend upon.

*If you're not already feeding a mineral balancer, try one of our 1kg trial bags.

In summary

Use LeakyGutCOMBO when the gut needs both stabilising and rebuilding at the same time. It often sits between a simple gut supplement and a full reset programme, helping create the conditions for longer-term digestive resilience.

LeakyGutCOMBO is a nutritional, functional food supplement and not veterinary medicine. For more on this, see Dr Kellon's article - Nutrition is not 'Alternative' Therapy .

♻️ Eco Note: Our packaging is recyclable and refillable.

LeakyGutCOMBO combines three complementary layers of support:

→ SiboCARE for microbial stability

→ GutAminos for intestinal lining support

→ Spirulina for nutritional and immune resilience

Together, they allow stabilisation and rebuilding to happen side by side.

Functional categories – gut support in action

1. Microbial terrain support - SiboCARE foundation
   - Supporting a balanced hindgut environment and helping maintain harmony within the microbial ecosystem.
2. Intestinal lining nourishment - GutAminos foundation
   - Providing targeted nutritional support for the cells that form the intestinal barrier and digestive lining.
3. Immune & antioxidant support - Spirulina
   - Supporting the immune-rich environment of the hindgut while providing valuable antioxidant and nutritional support.
4. Integrated gut resilience - SiboCARE + GutAminos + Spirulina
   - Working together to support the wider digestive environment, helping the gut settle and rebuild at the same time.

Big picture

Some horses need a reset, others need a rebuild. And some need both at the same time.

That's where LeakyGutCOMBO fits.

Its role is to bring together the key elements of stabilisation and rebuilding into one convenient blend for horses whose guts need support on multiple fronts.

Put simply, a resilient gut depends on both a stable environment and a strong barrier.

Advisories

LeakyGutCOMBO is formulated as a gentle, functional nutritional blend and is generally considered safe when used at recommended levels.

• Each component of this COMBO is available separately in our Gut System Shop page.
• Feed as a minimum 1-month course.

• Ensure quality adlib meadow hay is available at all times to help restore the beneficial hindgut microbiome.
• Contains natural bitter and antimicrobial-type compounds (e.g. Andrographis , Berberis , Oregano ) that help re-balance the microbiome. Introduce gradually to avoid transient digestive changes as the gut flora adjusts.
• If your horse is showing signs of discomfort or stress, consider supportive blends such as our DuoBute / StressTonic , or see our Hindgut Reset Programme.
• If a horse is receiving prescribed gastrointestinal, antibiotic, or anti-inflammatory medication, seek veterinary guidance before concurrent use.

Contraindications

• Not suitable for pregnant or nursing mares due to hormonally active and detoxifying botanicals.
• Avoid in horses currently on steroid, immunosuppressant, or anticoagulant medication unless under veterinary supervision.

What is LeakyGutCOMBO designed to support?

LeakyGutCOMBO is designed for horses experiencing ongoing chronic hindgut instability where both microbial imbalance and gut-lining support need addressing at the same time.

It is commonly chosen for horses with persistent faecal water, hindgut sensitivity, bloating, digestive instability, or recurring gut issues that never seem to fully settle.

What is "leaky gut" in horses?

Leaky gut is the term commonly used to describe increased intestinal permeability.

In simple terms, the gut lining acts as a protective barrier between the contents of the digestive tract and the rest of the body.

When that barrier comes under pressure from long-standing hindgut dysbiosis, inflammation, stress, or other challenges, its integrity becomes compromised.

This is why LeakyGutCOMBO focuses not only on microbial balance, but also on supporting the gut lining itself.

What's the difference between LeakyGutCOMBO and SiboCARE?

SiboCARE focuses primarily on stabilising the hindgut microbial balance and environment.

LeakyGutCOMBO contains SiboCARE but goes a step further by combining it with GutAminos and Spirulina.

• SiboCARE helps stabilise the environment.
• LeakyGutCOMBO helps stabilise the environment whilst simultaneously supporting the gut lining.
• Spirulina is an excellent natural hindgut deacidifier and mycotoxin binder.

What's the difference between LeakyGutCOMBO and GutAminos?

GutAminos focuses specifically on nourishing and repairing the intestinal lining.

LeakyGutCOMBO combines gut-lining support with microbial support and wider immune resilience.

My horse has faecal water syndrome. Is LeakyGutCOMBO the right place to start?

For many horses, yes.

Persistent faecal water involves both hindgut dysbiosis and compromise of the intestinal lining.

LeakyGutCOMBO was specifically created to address both aspects together.

Why does faecal water keep coming back?

This is one of the most common questions we hear.

Often, the issue isn't simply the faecal water itself - it's because the hindgut microbiome remains unstable and the gut lining has not fully recovered.

What is Spirulina doing in the blend?

Spirulina forms the third layer of the blend.

Spirulina provides nutritional support for the immune-rich environment of the gut, as it is an excellent deacidifier and mycotoxin binder, contributing to the wider resilience of the digestive system.

It forms the third layer of the programme, complementing the microbial and gut-lining support provided by SiboCARE and GutAminos.

How long should I feed LeakyGutCOMBO?

We generally recommend feeding LeakyGutCOMBO for a minimum of one month.

For longer-standing digestive patterns, many horses benefit from a longer course before moving onto the next stage of support.

Can LeakyGutCOMBO be fed long term?

LeakyGutCOMBO is primarily designed as a structured support programme rather than a permanent maintenance supplement.

Once the gut has become more stable, many owners transition to LKLCARE, foundation nutrition, BiomeTonic, WildFed, or a more tailored long-term plan.

How does LeakyGutCOMBO fit into the Hindgut Reset Programme?

LeakyGutCOMBO sits at the heart of the Hindgut Reset Programme.

The programme follows a structured sequence:

1. Alleviate (DuoBute)
2. Reset (LeakyGutCOMBO)
3. Restore (LKLCARE)

LeakyGutCOMBO is the central rebuilding phase where microbial support and gut-lining support come together.

My horse has allergies, skin issues, and faecal water. Should I consider KPUCOMBO instead?

If digestive issues are the primary concern, LeakyGutCOMBO is often the best place to start.

If faecal water sits alongside a wider picture involving sweet itch, pollen sensitivity, hoof quality concerns, behavioural sensitivity, respiratory issues, or recurring multi-system patterns, KPUCOMBO may be worth considering.

Can I feed LeakyGutCOMBO alongside StressTonic?

Yes. In fact, we recommend it.

Stress and digestive health are closely connected. Many owners choose to add StressTonic where anxiety, tension, routine changes, travel, or stress-related digestive disruption appear to be contributing factors.

What should my horse eat while on LeakyGutCOMBO?

For best results, we recommend a forage-first approach built around quality meadow hay, and avvoiding haylage at all times (due to the presence of lactic-acid bacteria), alongside a forage-balanced mineral balancer such as VitaComplete or EquiVita.

Long-term gut resilience relies as much on management and nutrition as it does on targeted supplementation.

How quickly will I notice a difference?

Every horse is different.

Some owners notice changes within the first few days, whilst others see a more gradual improvement over time.

For long-standing faecal water patterns, consistency and patience are important, as the goal is to support lasting stability rather than a short-term fix.
