More than a joint supplement, Steadfast Equine Performance offers unrivaled structural support without a loading dose for equine athletes.

Is your performance horse getting the complete structural support they need to protect them during training and competition? Whether you’re looking for a new joint supplement that offers maximum support for your active horse or you’ve already seen the results of our original Steadfast Equine loading dose, then Steadfast Equine Performance is for you.

Steadfast Equine Performance is made for horses competing and training at high levels. The stress and demands of a heavy training schedule, regular competition and deep footing expose competitors to chronic pain and career-altering soft tissue injuries. We’ve taken our original joint health formula and increased the amount of Natural Eggshell Membrane (NEM) to give competitors the additional support and protection they deserve.

For nearly a decade, top equine athletes have relied on a double dose (loading dose) of original, clinically proven Steadfast Equine to successfully support joints through the rigorous demands of frequent training and competition. Our veterinarians and nutritionists searched for years to discover an innovative, science-based ingredient that might offer additional support for horses in intense training. But the answer was right in front of us.

After searching the world over for an ingredient to enhance our original Steadfast Equine for high level athletes, we couldn’t find anything with more proven efficacy or competitive advantage than NEM. These performance horses just needed more of the proven ingredient they were already relying on. They needed an extra dose of NEM. Natural Eggshell Membrane (NEM) is what sets our formula apart from any other joint supplement available.

For Steadfast Equine Performance, we’ve doubled the amount of NEM in each dose. Instead of using a loading dose for times of heavy training or competition, Steadfast Equine Performance gives athletes continuous maximum level support at all times in a single dose. Each packet still contains the right amount of TêlaFIRM to support bones, tendons and ligaments. The combination of NEM and TêlaFIRM provide the most bioavailable ingredients that are easily absorbed and contain the proper balance of glucosamine, collagen, hyaluronic acid and chelated minerals. This means your horse can actually use the ingredients for maximum structural benefits.

Arenus is proud to offer Steadfast Equine Performance as an innovative soft tissue and joint supplement for daily, maximum structural support.


  • High level performance protection: The lifestyle of equine athletes is stressful on joints, soft tissue and bone. Heavy training schedules, regular competition, frequent travel and uneven footing can lead to career-altering soft tissue injuries and chronic pain. Steadfast Equine Performance protects and preserves your horse’s joint health to extend their career and keep them comfortable in training and competition. Also helps joint injections last longer.
  • Improved motion and flexibility: Performance horses with stiff, painful movement need total structural support for relief and comfort. Steadfast Equine Performance works fast with a powerful dose of Natural Eggshell Membrane to make your horse feel better for a longer stride length and more fluid motion.
  • Rapid repair and prevention: Horses on Steadfast Equine Performance recover faster from soft tissue injuries. Increased bone density, tendon strength, ligament strength and healthier soft tissues help prevent injury. Horses in training and competition need maximum support to keep them feeling and performing at their best.
  • Total structural aid: Complete structural support for healthy joints, soft tissue and bones. Made with the highest level of naturally occurring glucosamine, chondroitin, collagen and hyaluronic acid available. No other equine joint supplement offers the unique formulation and scientific backing of Steadfast Equine Performance.
  • Pre-measured single daily packets: Convenient, daily dose pouches come pre-measured for easy feeding and storage. No need to use two packets for a loading dose or during times of added stress. Your horse receives the maximum level of joint support in a single packet. Easy to travel with or store.



Our research-backed formula offers an enhanced version of our trusted Steadfast Equine joint health solution. Featuring a double dose of Natural Eggshell Membrane combined with chelated minerals to meet the demands of high level performance horses.

  • 2x natural protein NEM: Each packet of Steadfast Equine Performance contains a double dose of NEM compared to our original formula. Natural Eggshell Membrane provides a naturally occurring matrix of joint and structural support components that are synthetically manufactured in other supplements. NEM is a natural protein source that’s easily absorbed by horses for maximum structural support benefits. NEM results are proven more effective and faster acting than using traditional chondroitin and glucosamine [5]. In a human study, NEM provided significant improvement to knee and hip osteoarthritis pain and stiffness within 10 days [1].
  • TêlaFIRM trace minerals: Proprietary, double chelated mineral blend TêlaFIRM provides unmatched soft tissue support. Chelated, or organic minerals, are protected from the stomach’s acidic environment for safe passage to the small intestine. This allows horses to better absorb the minerals for maximum benefits. TêlaFIRM has been linked to profound clinical benefits such as increased bone breaking strength, decreased tendon, ligament and cartilage pathology and decreased incidence of synovitis [2] [3]. Unchelated minerals in other supplements are overfed to make up for poor absorption rates. TêlaFIRM does more with less by giving your horse quality minerals that their body can use.
  • Recyclable packaging: Eligible product for “Ride for a Green World” initiative. Save money while helping the environment! 
  • Clinically proven formula: Multiple studies have proved the effectiveness of patented Steadfast Equine to reduce pain, inflammation and the degradation of cartilage [4]. Other ingredients were tested by veterinarians to enhance the original formula for horses with higher stress levels, but after 10 years of extensive research, our proven NEM at a higher dose consistently yielded the best results.
