In the world of equine nutrition, choosing the right protein source can make a significant difference to your horse’s performance, recovery, and topline condition. Two terms that often come up are Pea Protein Isolate and Pea Protein Flour. While both are derived from yellow peas, they differ greatly in composition, digestibility, amino acid content, and application.
| Feature | Pea Protein Isolate | Pea Protein Flour |
| Protein Content | 85–90% protein | 20–50% protein (varies depending on grind and source) |
| Amino Acid Content | Higher amino acid concentration, including lysine | Lower amino acid concentration |
| Starch & Carbohydrate Levels | Very low | High — includes starch, sugars, and fibre |
| Digestibility & Refinement | Highly digestible and refined | Low to moderate; minimally processed whole pea product |
| Ideal Use Case | Performance horses, insulin-resistant/EMS horses, topline support | Budget bulk feed, weight gain (if starch isn’t an issue) |
| Price Point | Competitively priced, similar to many pea protein flours but with superior quality and effectiveness | Typically priced similarly depending on supplier and quality of protein |
Pea Protein Flour is a coarsely ground, minimally processed product made from yellow peas. It contains protein but also retains high levels of starch, fibre, and other plant matter. While it may offer some nutritional value, it’s a less efficient source of usable protein for horses — especially those with metabolic issues or needing muscle support.
Pea Protein Isolate is created through a refined extraction process that removes nearly all starch, sugars, and fibres, leaving a product that is over 85% pure protein. It’s easier to digest, naturally low in non-structural carbohydrates, and highly efficient at delivering key amino acids like lysine.
Balius Equine Nutrition offers Pea Protein Isolate because we believe horses deserve the highest-quality, most bioavailable protein source available — especially those in performance, recovery, or with metabolic sensitivities.
If your goal is to support lean muscle, recovery, or reduce starch intake, Pea Protein Isolate is the clear choice. It delivers more usable protein per dose and suits insulin-resistant or laminitic horses.
Pea Protein Flour may be used for basic supplementation or to add calories, but is less ideal for horses with sensitive metabolic systems.
At Balius, we offer Pea Protein Isolate because we believe horses deserve the highest quality, most bioavailable plant-based protein available.
Although most pea protein isolates on the market are expensive, our pricing is on par with many pea protein flours, making it an affordable yet much more effective solution.
Pea Protein Isolate is:
If you’re feeding for performance, recovery, topline, or metabolic stability, pea protein isolate is the superior choice — and the one we proudly stand behind.
