Because gut consistency is not luck, it’s management.
In good stables, “gut issues” aren’t a mystery, they’re a pattern. Change the hay, change the routine, change the environment, and you’ll often see it in appetite, manure consistency, temperament, and how well the horse holds condition.
You’ll recognise it fast: the same horse, same work, but suddenly they’re pickier, a bit tucked up, or just not holding their normal rhythm. Gut Biome is a daily nutritional gut support formula built to help maintain normal digestive function and feed utilisation as part of a balanced diet, so the feed you’re paying for actually has a fair shot at doing its job. It’s designed for real-world feeding, where forage varies, routines shift, horses travel, and you still want the program to stay steady.
The feed room truth: Consistency lives in the gut. When digestion is steady, everything else gets easier.
Why this formula earns its place
Buffer and balance support
Calcareous marine algae provides gut-friendly minerals that support a stable digestive environment.
Multi-pathway microbiome support
Yeast culture, MOS and beta-glucans support a healthy hindgut environment and day-to-day consistency.
Digestive efficiency support
Probiotics, digestive enzymes and active dry yeast support digestion and feed utilisation, so you’re not wasting quality feed.
Daily defence layer
A dedicated mycotoxin binder, plus antioxidant support from natural vitamin E and selenium yeast.

This is commonly used when owners want the gut side of the program to stay consistent through:
• feed and forage changes (and mixed hay quality)
• travel, stabling changes, new paddocks, new routines
• training blocks where appetite and condition matter
• horses that are “fine at home” but get weird when the routine changes
• horses that are “a bit sensitive” when life changes
Why this is different to most gut products
Many gut tubs are single-lane (buffer only, probiotic only, yeast only). Gut Biome combines buffering, fermentation support, microbial support, and binder support in one daily program.
What the ingredients do, and why this formula works as a system
1. Buffer and stabilise the digestive environment -
Calcareous marine algae supports natural buffering, helping keep the gut environment steadier and more predictable.
2. Support fibre fermentation and hindgut function -
Yeast culture supports the microbes that ferment fibre, helping horses get more consistent value from hay.
3. Support microbial balance and gut defence -
MOS plus beta-glucans help manage unwanted microbial pressure (MOS acts like a decoy), and support normal gut immune function.
4. Help break feed down properly -
Probiotics plus digestive enzymes support microbial balance and more reliable digestion, especially during change.
5. Real-world forage protection -
A mycotoxin binder supports resilience when hay isn’t perfect, helping protect appetite and consistency.
6. Support layer for horses in work -
Natural vitamin E plus selenium yeast support antioxidant status and normal muscle function.
Directions
Introduce gradually over 7–10 days. Mix the daily dose with a forage-based feed (e.g., chaff, beet pulp, soaked hay pellets). Moisten lightly if needed to prevent powder loss. Feed at a consistent time each day for best results. Ensure access to clean, fresh water at all times.
Enhanced support option
During stress or transition periods, split across three feedings (AM, midday, PM) to mimic grazing and maintain continuous support.
What to expect
This isn’t a “feel it in 30 minutes” product. It’s daily gut insurance. Most people aren’t chasing a dramatic “before and after”. They just want the horse to stay more consistent when life changes.
Over the first couple of weeks, the usual wins are steadier manure, a more reliable appetite, and fewer random off days when the hay, routine, or environment shifts.
