PROTEK GI Proven for Ulcer-Prone Horses
When you ask the questions, we listen!
The top three questions consistently asked about gut health supplements for horses with or at risk of gastric ulcers are:
- Is this product backed by science?
- What evidence is there to prove it works?
- Will this supplement do what it says it will?
Kelato can confidently answer all of these. And here’s why PROTEK GI is the supplement you can trust to manage the ongoing health of your ulcer-prone horse.

1) Is this product backed by science?
Not only is it already supported by one peer-reviewed clinical trial but now there are TWO!
“Very few supplements are supported by real research, let alone a clinical trial in a real-world population of horses with real-world disease. PROTEK GI has not one, but two, clinical trials supporting its efficacy making it really stand out from other supplements” says Dr Ben Sykes BSc BVMS MS MBA DipACVIM PhD FHEA.
This growing evidence is just one reason to consider PROTEK GI when looking for a supplement as part of a long-term ulcer management plan.
2) Is there evidence to prove it works?
With the overwhelming number of gut health supplements on the market, it can be hard to determine the right choice for your horse. Published evidence helps guide your decisions, making you better equipped to support your horse.
It's one thing to develop a supplement based on a scientific rationale. It's another to investigate the complete product formulation in horses and to have the findings published in a peer-reviewed scientific journal.
A recent peer-reviewed clinical study on PROTEK GI showed that daily supplementation reduced the incidence and severity of gastric ulcers following discontinuation of omeprazole in a population of racehorses (Shan et al., 2023).
PROTEK GI is a research-proven tool to add to your ulcer management toolbox.

3) Will this supplement do what it says it will?
PROTEK GI’s blend of pectin, lecithin, and buffers creates its signature alkaline slime.
These ingredients act as coating agents in the stomach which is key for ulcer-prone horses. They work by forming a barrier over the stomach lining to help:
- Protect it from acid burn
- Promote mucosal health
- Strengthen normal defence mechanisms
For hindgut health, PROTEK GI includes a unique Agrimos® prebiotic and live Levucell SC® S. cerevisiae CNCM I-1077 probiotic, which work together to help stimulate the growth and activity of beneficial hindgut bacteria. Together, they help to:
- Stabilize the hindgut microflora balance in favor of good bacteria
- Optimize feed conversion efficiency (great for improving body condition)
