Every horse is an athlete. That is the belief that Big Hoss was built on. Whether your horse is competing at the highest levels of their discipline, heading out for weekend shows, hitting the trails on Saturday mornings, or spending their days in a pasture as a beloved companion, they share the same fundamental nutritional needs — and most of them are not getting what they require from hay and grain alone.
Big Hoss is Outlaw Nutrition’s premium equine supplement. It combines cold-milled flaxseed — the richest plant source of omega-3 fatty acids available — with a unique microbial fermentation ingredient that works at the level of the gut microbiome to drive better digestion, stronger immunity, faster recovery, and more complete utilization of every pound of feed your horse consumes. The result is a supplement that addresses the root causes of poor performance, slow recovery, compromised coat and hoof health, and digestive instability — not just the symptoms.
The Nutritional Gap Most Horse Owners Don’t See
The modern horse diet has a problem. Hay, the foundation of most equine feeding programs, loses a significant portion of its natural omega-3 content during harvesting and storage. Grain-based feeds are high in omega-6 fatty acids, which compete directly with omega-3s in the body’s inflammatory pathways. The result, for most horses on typical hay-and-grain programs, is a chronic omega-3 deficiency that quietly limits how well they feel, perform, and recover — day after day, without any single symptom pointing directly to the cause.
Omega-3 fatty acids are required nutrients. The horse’s body cannot produce them on its own. They must come from the diet. And when they are consistently absent or insufficient, the consequences show up across every system in the body — joints that stay inflamed longer after hard work, coats that lack shine and luster, hooves that grow slowly or crack, immune systems that are slower to respond, and digestive systems that operate below their potential.
Flaxseed is nature’s answer to this problem. It contains 55% omega-3 alpha-linolenic acid (ALA) in its oil — nearly eight times more omega-3 than soybean oil and more than fifty times more than corn oil. Big Hoss is built on cold-milled non-GMO flaxseed specifically because cold-milling preserves those omega-3 fatty acids intact, delivering them to the horse’s body without the degradation that heat processing causes. The result is a guaranteed minimum of 12% omega-3 content, 25% crude fat, and a caloric density of 2,600 kcal per pound — clean, sustained energy without excess starch or sugar.
The Gut Health Ingredient That Sets Big Hoss Apart
The second major component of Big Hoss is a unique microbial fermentation ingredient that works fundamentally differently from any probiotic on the market. It is non-viable — meaning it contains no live bacteria — and instead works as an abiotic, feeding and activating the native beneficial bacteria already present in your horse’s digestive tract rather than trying to introduce foreign cultures that may or may not survive the journey through stomach acid.
The practical effects of this ingredient on equine health are well documented. It reduces lactic acid production during exertion — the primary driver of muscle soreness, fatigue, and slow recovery after hard work. It improves the efficiency of nutrient absorption in the gut, meaning your horse gets more out of every pound of feed. It supports a proactive immune response, keeping the horse’s defenses ready rather than scrambling to catch up. And it maintains digestive stability through the stress events — travel, competition, feed changes, weather — that commonly trigger digestive upset in performance horses.
Critically, this ingredient is fully compatible with antibiotics and all other medications, requires no refrigeration, and has a shelf life of 18 to 24 months at room temperature. It will not cause antibiotic resistance — a significant advantage over live probiotic cultures.
What Big Hoss Does for Your Horse
The combination of cold-milled flax and the unique microbial ingredient creates a supplement that delivers across every area of equine health that matters to owners and trainers.
For performance horses, the primary benefits are faster recovery, reduced muscle soreness, better exercise tolerance, and a calmer, more focused temperament. Horses on Big Hoss cool down more quickly after hard work, return to training readiness faster, and maintain condition more consistently through demanding competitive schedules. The omega-3s reduce the inflammation that accumulates in joints and soft tissue during intense training, allowing horses to do more work with less physical cost.
For horses prone to digestive issues — stomach ulcers, hindgut acidosis, or chronic soft stool — the combination of flax mucilage fiber and the microbial ingredient provides meaningful support. The soothing fiber forms a protective coating along the digestive tract, while the microbial ingredient helps restore and maintain the bacterial balance that healthy digestion depends on. Owners consistently report that horses that struggled with digestive instability before starting Big Hoss show marked improvement within the first 30 days.
For horses with laminitis history or those at risk — particularly easy keepers, ponies, and horses on high-starch diets — Big Hoss is formulated without the sugar and starch that trigger laminitic episodes. The omega-3s support healthy circulation and reduce the systemic inflammation that contributes to laminitis development. Research from the AAEP found that horses supplemented with flax-based omega-3s showed no lameness in laminitis challenge trials, while all control horses developed the condition. Big Hoss does not treat laminitis, but it provides the nutritional foundation that supports healthy hoof tissue and circulatory function.
For horses with HYPP or metabolic sensitivities, the low-starch, low-sugar formulation of Big Hoss makes it a safe addition to a carefully managed feeding program. Always consult your veterinarian for specific management protocols, but the nutritional profile of Big Hoss is designed with metabolically sensitive horses in mind.
For coat, skin, and hoof health — one of the most visible indicators of overall nutritional status — Big Hoss delivers results that owners notice quickly. The omega-3s support the production of natural skin oils, reduce the inflammation that causes dull, flaky coats and skin irritation, and improve the quality of keratin production in hooves. Horses that arrive looking rough and dull come out the other side with coats that turn heads at the barn and at shows. Hoof quality improves measurably within a single growth cycle.
For trail horses and leisure horses — the horses that may not be in hard competition but deserve to feel their best every day — Big Hoss provides the same comprehensive nutritional support. A trail horse that is comfortable in their joints, settled in their gut, and vibrant in their coat is a more enjoyable, more capable partner. A leisure horse in genuinely good health lives a better life. Big Hoss is not just for elite competitors. It is for every horse whose owner cares about doing right by them.
What Big Hoss Owners Are Saying

Practical Details: Feeding, Sizing, and Competition Compliance
Big Hoss is top-dressed over your horse’s existing feed — no special mixing, no complex preparation. The serving size is 1/2 cup per 350 pounds of body weight per day, adjusted up or down based on the individual horse’s weight, age, condition, and level of work. For an average 1,100-pound horse, a 50lb bag of Big Hoss lasts approximately three months.
Big Hoss is available in 25lb bags, 50lb bags, bucket quantities, and PAX individual serving packs for the convenience of travel and shows. It is screened for compliance with USEF, FEI, IFHA, and HIWU standards, making it safe for use in sanctioned competition without concern. It is produced in a Safe Feed/Safe Food certified facility, carries a 2-year shelf life when stored properly in a cool, dry location, and is compatible with all existing feed programs, medications, and supplements.
Give Your Horse What They Require
Big Hoss is not a one-trick supplement. It does not address a single problem and leave everything else to chance. It addresses the foundational nutritional gaps — omega-3 deficiency and suboptimal gut health — that limit how well horses feel, perform, recover, and thrive at every level of work and life.
