Our Story 

Every great company starts with an idea.

​

Ours began with more than an idea—it began with over 30 years of experience in systemic enzyme science.

​

For decades, we've developed enzyme formulations that support people and companion animals—not by simply masking discomfort, but by supporting the body's natural processes involved in recovery and wellness.

​

Through that experience, we saw firsthand the unique potential of systemic enzymes in supporting healthy inflammatory responses, normal tissue recovery, and the body's ability to manage the effects of physical stress.

​

That led us to ask a simple question:

​

Why weren't horses benefiting from this same science?

​

As lifelong horse people, we understood the physical demands placed on our equine partners. Whether they're chasing a championship, working cattle, covering miles on the trail, or simply enjoying life in the pasture, every horse deserves the opportunity to feel and perform at their very best.

​

That idea stayed with us for years.

​

We weren't interested in creating just another supplement. If we were going to do it, we wanted to do it the right way—combining decades of systemic enzyme expertise with premium ingredients and uncompromising quality to create unique formulations we'd confidently use on our own horses.

​

After years of research, development, and refining our vision, Steel Horse Formulations became a reality.

​

More Than a Supplement Company

Steel Horse Formulations brings together 30+ years of systemic enzyme expertise with a lifelong passion for horses and the animals we share our lives with.

​

Our experience extends beyond the barn. For decades, we've developed enzyme-based products that support the health and wellness of people and companion animals, applying the same scientific standards and commitment to quality every step of the way.

​

Our horses aren't marketing tools—they're part of our family. They challenge us, teach us, and inspire everything we do.

​

Because we live this lifestyle every day, we understand what it means to care for an equine partner and how important it is to keep them healthy, comfortable, and ready for whatever comes next.

​

A Different Approach to Equine Wellness

Many supplements focus on adding nutritional support or addressing individual areas of concern. We believed there was an opportunity to take a different approach.

​

Not by masking discomfort, but by supporting the body's natural recovery processes.

​

That philosophy is what led us to develop SerraQuin®.

​

Powered by systemic enzymes, SerraQuin was created to support a healthy inflammatory response, normal tissue recovery, and overall mobility. It represents a science-based approach designed to help horses recover, perform, and maintain comfort throughout their lives.

​

From performance athletes to trusted trail partners and beloved companions, every horse deserves access to thoughtful formulation backed by experience and innovation.

​

Why Steel Horse?

The name Steel Horse represents the values this company was built on.

​

Strength.

​

Resilience.

​

Integrity.

​

Dependability.

​

Just like the horse has stood beside mankind for generations—working hard, carrying us farther than we could go alone—we believe they deserve products created with the same dedication they give us every day.

Those values guide every decision we make, from the ingredients we select to the standards we refuse to compromise.

​

Our Commitment

We're proud to be an American company serving horse owners who expect more than flashy labels and marketing claims.

​

Our commitment is simple:

  • Formulas built on science.

  • Premium ingredients selected with purpose.

  • Products we trust enough to use in our own barn.

  • Honest customer service from people who genuinely care about horses.

​

Whether you own one trusted trail horse or a barn full of elite athletes, we're honored to be a small part of your horse's journey.

​

Thank you for trusting Steel Horse Formulations.

​

MAXIMIZE PERFORMANCE.
         MINIMIZE DOWNTIME.

​

Forged by Those Who Live It.

Forged by Experience.

​

Steel isn't forged in comfort. It's forged through heat, pressure, and time.

We believe great products are built the same way.

​

Years of experience, relentless testing, and an unwavering commitment to quality have shaped every formula we create.

​

That's what Steel Horse means to us.

​​​

We are a Company of our Word.

 

Sincerely,


Brad Custer
CEO & Founder
