EQUINE PRO-STEM combines two powerful functional oils — Castor Oil and Cashew Nut Shell Liquid — to create a unique formula with standardized active components.
EQUINE PRO-STEM is a combination of two functional oils: castor oil and cashew nut shell liquid (not the nut itself). Vermiculite (silica) is used as a carrier to ensure optimal delivery.
A unique fatty acid with powerful anti-inflammatory and antimicrobial properties that supports digestive health.
A natural phenolic compound with potent antioxidant and antibacterial effects.
A bioactive compound that enhances immune response and supports overall wellness.
Scientific study on the effects of EQUINE PRO-STEM supplementation on blood parameters in Thoroughbred horses under heavy training.
7 Thoroughbred horses under heavy training supplemented with 10g/day for 21 days
Comprehensive blood panel including RBC, WBC, electrolytes, enzymes, and proteins
ANCOVA analysis with serum albumin as covariate for hydration state
Higher oxygen transport capacity
Improved bone health and muscle function
Improved energy metabolism, less acidosis
Better electrolyte balance
Better cell membrane integrity, less tissue damage
EQUINE PRO-STEM supplementation improved the antioxidant capacity and energy metabolism of training racehorses. The antioxidant activity appears to increase red blood cell lifespan, while improved energy metabolism results in less oxidative stress and better cell membrane integrity. These findings indicate either enhanced antioxidant capacity, more efficient energy production, or both.

William Knight Racing LTD
"Feeding EPR to my racehorses during 2024 was a new addition that has significantly improved my 2024 results to an all-time record on the racecourse. I proudly had my best year ever in 19 years of training in 2024."— William Knight, February 2025
Independently tested and certified to not contain any banned substances. A natural product with no synthetic additives.
Natural fats provide slow-burning fuel steadily released, helping maintain endurance over long distances without energy spikes.
Anti-inflammatory properties reduce joint pain. Older horses previously needing regular injections required none in 2024.
Reduced muscle fatigue and soreness allowed horses to run more frequently - 10-12 races vs typical 6-7 per season.
Improved coat shine and skin condition, reducing dry, flaky skin and ensuring horses look as good as they perform.
EQUINE PRO-STEM works through multiple pathways to deliver comprehensive health benefits for your racehorse.
Disrupts cell wall integrity of gram-positive bacteria
Further destabilizes protozoa cell walls
Result: Two modes of action make the product more effective and significantly reduce the chances of resistance developing.
Everything you need to know about EQUINE PRO-STEM.
EQUINE PRO-STEM is a combination of two functional oils: castor oil and cashew nut shell liquid (not the nut itself). The active components are ricinoleic acid, cardol, and cardanol. Ricinoleic acid comes from castor oil, with cardol and cardanol coming from cashew nut shell liquid. Vermiculite (silica) is used as a carrier.
The natural antimicrobial activity in EQUINE PRO-STEM has two modes of action (disrupting both monovalent and divalent cations) to disturb and destroy the cell walls of gram-positive bacteria and protozoa. Having two modes of action not only makes the product more effective, but also significantly reduces the chances of resistance developing. EQUINE PRO-STEM is able to target strains of Eimeria, the protozoa that causes Coccidiosis, as well as Clostridium, which causes necrotic enteritis.
The levels of ricinoleic acid, cardol and cardanol get tested in the raw materials, during manufacturing, and of course in the final product. Using NIRS (near infrared spectroscopy) the levels of these three active components can even be tested after it has been mixed in feed.
EQUINE PRO-STEM has received the FAMI-QS Certification, a more stringent and feed additive/premix specific version of GMP. All of the EQUINE PRO-STEM ingredients are approved by AAFCO (Association of American Feed Control Officials).
Phytogenics, or essential oils, can be easily confused with EQUINE PRO-STEM due to the name and that both are plant based. However, phytogenics are made from herbs and spices with some of the most common being: thyme, rosemary, cinnamon, chili, and oregano. The active components of these ingredients are usually not standardized, which results in inconsistent and unreliable performance. The functional oils in EQUINE PRO-STEM are able to pass through the stomach and target the intestinal tract, where the microbial challenge is, whereas some phytogenics get broken down in the stomach.
There has been no evidence or indications of toxicity or risk with over-dosing with EQUINE PRO-STEM. The castor bean plant is occasionally associated with the toxin ricin, however ricin is hydrophilic (water affinity) whereas castor oil is lipophilic (oil affinity). The process used to get castor oil eliminates ricin from contaminating the oil. Castor oil is also a common ingredient for many cosmetic products, as well as used as a laxative on its own.
Quite the contrary, there will be a positive effect on faeces quality. EQUINE PRO-STEM has a dosage of castor oil that can maintain its biological activity, without having a laxative effect. Between the decrease in microbial challenge and improved nutrient absorption, the faeces will be drier and less odorous. Improvement in faeces is commonly the first observed sign of activity after supplementing EQUINE PRO-STEM.
Feed ingredients like acidifiers, pre/pro/syn-biotics, or enzymes can be included at the same time with no counter-indications. If there is a need for antibiotic treatment, the animal's response will be improved with EQUINE PRO-STEM due to improved overall health and immune response.
The activity of EQUINE PRO-STEM can handle a 5-year shelf life from date of manufacturing. The product should be kept out of direct sunlight and avoid getting wet (high humidity has no effect). The active ingredients can also handle high temperatures and are unaffected by extrusion, even for dog food (at ~150°C). EQUINE PRO-STEM can undergo any processing for feed (pelleting, crumbles, extrusion, etc.) without losing activity or disrupting feed quality.
Simple, effective supplementation for optimal results.
Per day per horse
Based on extensive research, the recommended dosage of EQUINE PRO-STEM for horses is 10g per day, to be added to their feed as a supplement.
EQUINE PRO-STEM should be supplemented to the feed ration of horses at the earliest stage possible.
Improvement in feces quality is commonly the first observed sign of activity after supplementing EQUINE PRO-STEM.
Significant benefits typically observed after 21 days of daily supplementation, including improved performance and recovery.
The longer EQUINE PRO-STEM is included in the diet, the better the overall health and performance outcomes.
Processing Compatible: EQUINE PRO-STEM can undergo any feed processing (pelleting, crumbles, extrusion, etc.) without losing activity or disrupting feed quality. Active ingredients handle high temperatures up to ~150°C.
EQUINE PRO-STEM meets the highest industry standards for quality, safety, and efficacy.
A more stringent and feed additive/premix specific version of GMP, ensuring the highest quality standards in manufacturing.
