BIOMETONIC -🌱MARCH SPRING SALE - 20%-OFF *Organic herbal blend for horses - intestinal-balancing, parasite disruption, everyday gut resilience
Nature’s aromatic ecology - supporting the hindgut the way horses evolved to maintain it.
BiomeTonic brings together aromatic, polyphenol-rich herbs traditionally used to help keep the digestive environment clean, balanced, and resilient against parasites and pathogens, used for generations to help support the gut’s natural “housekeeping” system.
It’s not a probiotic, and not a dysbiosis reset formula - it simply supports the internal conditions where beneficial microbes thrive and unwelcome organisms struggle to gain ground.
The result? A happier GI tract, steadier digestion, and a whole lot less " don't touch me there ! ".
✨ “What a difference in just 24 hours - no more biting, and I can touch his belly comfortably now!” Emma

Overview
For the last 10-years or so we’ve been tracking the science of the equine gut biome, and the truth is: horses don’t need us to add microbes - they need us to feed the ecosystem that’s already there.
The equine gut evolved on diverse grasses, herbs, and plant compounds that naturally nourished their microbial community. It wasn’t designed for added factory-farmed yeasts, lactobacillus blends (which acidify the hindgut, making microbial sensitivity worse , not better), or sugar/starch-based “gut balancers.”
Equally, when plant diversity depletes – through modern grazing, processed feeds, stress, or medication – the internal environment can shift, which means the balance between beneficial microbes and opportunistic organisms shifts with it.
BiomeTonic follows the ecological model horses evolved with.
Rather than adding microbes, it supports the digestive environment itself – helping maintain microbial steadiness, digestive tone, and everyday intestinal comfort.
Paired with quality meadow hay and fibre-first feeding, this approach works with the hindgut’s natural intelligence: diverse, aromatic, cooperative, and self-regulating.
In short? Healthy forage + natural prebiotic fibres + aromatic herbs = a balanced microbiome. BiomeTonic simply helps maintain that balance, day after day)
Is BiomeTonic Right for Your Horse?
BiomeTonic is formulated for ongoing intestinal maintenance once stability has been achieved, based around aromatic oily herbs that help discourage everyday unfriendlies, keeping the digestive environment calm and stable over time.
Choose BiomeTonic if your horse:
✔ benefits from daily or alternate-day gut support
✔ becomes girthy, reactive, or sensitive through the belly
✔ needs help maintaining microbial balance long-term
✔ has completed a SiboCARE or gut reset programme
BiomeTonic is not:
- a dysbiosis-correcting formula (use SiboCARE first)
- a gastric-ulcer blend (see UlsaTonic )
- a mucosal repair support (see GutAminos )
Which blend - BiomeTonic, SiboCARE, or LeakyGutCOMBO?
Each supports a different stage of gut recovery and resilience:
→ BiomeTonic
Maintenance | Microbial balance | Belly comfort
For maintaining microbial balance once stability is achieved.
→ SiboCARE
Active dysbiosis | Gas & bloating | Microbial overgrowth reset
For unstable hindgut dysbiosis - gas, bloat, right-hind pain, post-antibiotics instability.
→ LeakyGutCOMBO
Faecal water | Mucosal nourishment | Gut-lining support
For chronic hindgut fragility, i.e. leaky gut/faecal water.
Composition & Feed Guide
Each herb in BiomeTonic plays a targeted role in supporting a balanced, comfortable digestive system.
BiomeTonic is a nutritional food supplement and not veterinary medicine. For more on this, see Dr Kellon's article - Nutrition is not 'Alternative' Therapy

Energetic Architecture - the 'synergy' behind the blend
Energetic architecture describes how a blend supports the body’s natural processes working together.
BiomeTonic is designed around the microbial–mucosal–digestive tone axis – the internal environment that determines whether beneficial microbes flourish and opportunistic organisms lose ground.
Rather than adding microbes or aggressively clearing dysbiosis, BiomeTonic supports the conditions that allow the hindgut ecosystem to remain balanced, stable, and self-regulating.
Functional categories – intestinal terrain support in action
- Aromatic microbial regulation - Origanum, Thymus, Salvia officinalis
- Fungal & microbial terrain balance - Tabebuia impetiginosa
- Digestive tone & gut–liver axis support - Salvia rosmarinus
- Mucosal calming & aromatic buffering - Matricaria recutita
Functional intent
The hindgut doesn’t usually destabilise because microbes are “missing.” It destabilises when the environment shifts- when plant diversity is lost, when fibre quality changes, or when microbial competition becomes unbalanced.
In short? It restores the conditions the hindgut evolved to recognise - diverse, aromatic, fibre-based terrain - rather than imposing an artificial solution.
Clinical Considerations / Veterinary Reference
Advisories
- Always ensure the forage foundations are in place - feed alongside quality fibre-rich meadow hay.
- For right-hind gut pain or strong dysbiosis, use SiboCARE first.
- For faecal water or mucosal fragility, use LeakyGutCOMBO or contact us for guidance.
Contraindications
- Not suitable for pregnant or nursing mares due to the natural aromatic and cleansing activity of the herbs.
- Avoid concurrent use with anticoagulant medications.
- Not advised during acute infection, fever, or active ulcer episodes.

The Story Behind BiomeTonic
From Carol Moreton, Founder of EquiNatural
BiomeTonic was originally formulated for one unforgettable pony - Mac, affectionately (and accurately) known as MacAttack.
Mac had a gut so reactive that reaching under his belly to fasten his sweet-itch rug was a genuine hazard. One wrong move and he’d cow-kick with the accuracy of a guided missile.
I didn't know it at the time but in 2021, when I studied the KPU disorder with Dr Christina Fritz, I learned that this was a pure gut-driven pain reaction.
For 15-months we took MacAttack through what then became our KPU programme, and when we finally got him stable, I needed a way to keep him that way.
That’s where the oily herbs came in. BiomeTonic became the blend that meant I could finally reach under Mac again to do up his sweet itch rug without risking losing my arm.
It kept his gut comfortable,and importantly - his mood so much better! Eventually he levelled out, and we got himto where he only needed it every couple of weeks as a preventative.
If your horse is a little “MacAttack” at times, BiomeTonic was made for them.
