Your horses’ health is under attack

As you probably know…

 

Horses are as delicate as they are beautiful and laborious.

 

It’s incredibly hard to keep them in tip-top shape, fully productive and happy year-round.

 

Stress, work, aging and injuries can lead to lameness and a myriad of health issues…

 

And there’s one underlying root cause: Inflammation.

 

Inflammation is the basis of pain, discomfort, slower healing, and many serious, progressive problems.

 

If your horse is dealing with injuries, infections, hoof problems, lameness, degenerative conditions, or eye illnesses…

 

Inflammation is why they struggle to recover fast and completely.

 

The longer this goes unsolved, the more their quality of life gets affected…

 

Which can lead to changes in temperament, depression or lethargy.

 

And unless this inflammation is addressed, some health issues can become chronic…

 

Putting a serious strain on your horses' performance, well-being, and even their life.

 

So how do we reduce inflammation?

 

Inflammation is driven by the buildup of inflammatory proteins…

 

These inflammatory proteins are silently flooding your horse's body, creating a cascade of destruction…

 

Every moment they remain, they trigger more pain, more swelling, more damage…

 

And the condition they are suffering from continues to exist.

 

Left unchecked, these proteins will continue their relentless assault…

 

Robbing your horse of its vitality, performance, and joy of movement.

 

The problem? Most products in the market fail to target them.

 

Only two options exist, supplements and NSAIDs.

 

Most supplements are formulated with plant-based extracts (on top of chemicals and fillers which actually lead to inflammation).

 

These extracts lack the potency to affect inflammatory proteins fast enough as they usually need weeks if not months of build-up for them to start yielding results.

 

Also, they are often not fully bioavailable, so you’re not really getting what you pay for.

 

Then we have NSAIDs.

 

These work by reducing the production of prostaglandins, which are molecules that signal to the body to drive inflammation.

 

While this can help manage some of the symptoms of inflammation… 

 

It doesn't address the inflammatory proteins that continue to cause ongoing pain, slower healing and reduced performance in horses… 

 

Plus, the long-term use of NSAIDs has been associated with harmful side effects.

 

But unlike any other product on the market today…

 

Serraquin ES15® consists of a potent enzyme blend. 

 

Enzymes are specialized proteins that your horse's body already uses every day…

 

Think of them as nature's master workers - they speed up virtually every biological process in your horse's body.

 

From digesting food to healing wounds to fighting inflammation.

 

Without them, these vital processes would be too slow to sustain life.

 

That's why Serraquin ES15® is special enzyme blend is so powerful…

 

It acts like tiny biological scissors that target and break apart proteins that cause inflammation.

 

In essence, it acts like a cleanup crew in the whole body… 

 

Helping to remove unwanted proteins and reduce inflammation, leading to faster healing.

 

And because enzymes are 100% natural, it’s safe for any horse and free of side effects.

 

So, if you want a healthier, happier and more productive horse…

 

Please consider adding Serraquin ES15® as an integral part of your feeding program. You will not be disappointed.

Backed By Science

A trial study with the ingredients in Serraquin ES15® was conducted on six racehorses suffering from non-specific lameness.

 

The results of the study indicated that five of the six injured horses showed complete recovery, while the one horse that did not respond was later found to suffer from ligament tears that would require surgery to completely heal.

The Bombay Veterinary College Department of Surgery conducted a controlled study using 18 buffalo calves 

 

Calves were divided into three groups of six. Group one was given Serraquin ES15™, group two was given traditional antibiotics, and group three was given antibiotics and anti-inflammatories. 

 

Of the 18 calves, the 6 that were administered Serraquin ES15™ showed the shortest post-surgical recovery times, far less swelling around the wound, and far less visible infection.

Goodbye Equine Lameness

WOW! I originally purchased this for my 19 yr old rescue mare for a pretty significant "arthritic knot " on her front leg. What a difference it has made in reducing the swelling. 

 

Added bonus is her top line looks better, coat and mane are both outstanding. You have a customer for life!

Not Just A Joint Supplement, A Whole-Body Healing Solution

This was a month ago. He had punctured his eye, leading to a fungal infection. Pre-purchase exam still showed a tiny bit of fungus. I brought him home, treated for the infection, and started him on Serraquin. 

 

Upon eye recheck, fungus was gone, and the vet was impressed with the lessening of scar tissue. He thought it would never go away.

 

It is MUCH improved. It is now translucent and when looking from behind, I can see straight through the thin scar tissue.

 

I’ve used Serraquin for my EPM horse and it made a HUGE difference there also. Thank you, Brad, for your help and an incredible product.

Why We Created Serraquin ES15®
Steel Horse Formulations Founders of Serraquin.jpg

We are not only horse people, but we are a company that prides itself on our expertise and knowledge of systemic enzymes and their benefits.

 

Steel Horse Formulations began with the experience and knowledge of using systemic enzyme therapy for humans extending across the world in over 80 countries. Therefore, we decided to introduce this amazing therapy to the forefront of the equestrian world. Not only have we had this experience with enzymes, but we have been lucky enough to be involved with performance horses for even longer. With all the supplements for horses on the market today, we felt it necessary to share this one-of-a-kind therapy for equine lameness and overall health.

 

​We know what it takes to keep our four-legged athletes sound, healthy and ready to perform. It isn’t always easy, as we all know horses will find a way to hurt themselves, even in a rubber room! 

 

After countless years and many discussions with the number one enzymologist in the world, we were finally able to introduce Serraquin ES15™ to the market! The bar has been raised to unparalleled heights in the fight against equine inflammation & health conditions.

 

We sincerely hope that your equine friends experience the same benefits for a long time.

 

Sincerely,

Brad Custer, CEO & Founder

Happier horses, guaranteed.

We stand behind our product with a promise of transparency and reliability, supported by scientific evidence.

Frequently Asked Questions

What is Systemic Enzyme Therapy?

Systemic enzyme therapy refers to the therapeutic use of natural enzymes to produce desired healing effects. Systemic enzymes are absorbed in the intestinal track where they enter the bloodstream. Then they carry out desired benefits throughout the body.

Why is Serraquin ES15 unlike any other Joint Formula on the Market Today?

Unlike many Joint Formulas on the market that contains Glucosamine and HLA, Serraquin takes a different approach by using a unique blend of systemic enzymes that have been used worldwide for 50 years for inflammation and pain in people. Serrapeptase, a fundamental ingredient in Serraquin has been thoroughly researched for its' numerous and diverse effects on inflammation, pain, infection and healing. Unlike medicines used to block COX enzymes to suppress inflammation Serrapeptase actually digests the pro-inflammatory prostagladin that causes inflammation. 

 

Serraquin ES15, a superior blend of enzymes not only promotes a healthy inflammatory response but also enhances healthy fibrin levels which in excess cause scar tissue and adhesions. 

 

Serraquin is the most advanced joint formula on the market today and should be first line of defense for equine lameness.

Is Serraquin es15 safe for my horses?

 

Yes, Serraquin is safe for any horse, including working horses, senior horses & pregnant mares. Plus, it’s also safe for competition horses since it is FEI & USEF compliant.

What is the best way to administer Serraquin ES15

 

As horse people we know that all horses are not all the same. Some don't mind certain taste and some are finicky. Luckily Serraquin ES15 is a tasteless powder that can be added directly to grain, pellets, beat pulp or any other type of feed alike with a small amount of water to mix into the feed. It can also be used with other supplements. 

 

Although Seraquine ES15 is tasteless... some finicky horses may still decide otherwise. If this does happen you may also mix the powder with a small amount of water (3-4 drops) to make a paste and admister with syringe like any other paste such as wormers.

My 25 year old gelding is on month 2 using this product; what a difference it's made! He's a retired high-level roping horse with navicular and arthritis. He's my absolute ❤️ horse. After trying him at drill, he became extremely lame; fortunately, I had just started him on Steel Horse, and he recovered after 3 days. He has a lot of go in him still, Steel Horse is allowing him to move without pain. He's even bucking in pasture. Thank you!!

working!

Love Serraquin, been using for a year now for my IR and rotated arthritic gelding. He used to have inflammation and soreness constantly despite the right diet for him, since starting him on Serraquin from recommendation from my farrier. He’s moving a lot easier and seems all around more happy. I tried tons of other supplements and nothing quite helped until this one! Rather spend my money on one supplement than 5 that don’t work!

Laminitis

After 1 1/2 years and trying different remedies. This one worked. He’s been on it for 3months now and is finally walking normally. I believe we may be able to ride again with the cavallo boots on or his epic easy boots. On( he’s always has worn boots) thin sole too. He’s been on a low carb diet and short turnout time in pasture. I’m glad something has finally kept him comfortable and on the mend now.

a miracle product

I have an older Arabian gelding with ringbone and cushings. Steel Horse has been a game changer for him. Truly a game changer for me as well, I no longer see the discomfort in his eyes. He is happy and sassy, as he should be. Thank you Steel Horse!

My yearling, Jameson, participated in the APHA Youth Yearling Futurity this year. At the prep show a month before the World show he became sore on all the hard ground. I did not want to put shoes on him so I started him on the Serraquin ES. He stayed sound on all the concrete at Fort Worth and showed well. He placed seventh overall and his highest placing was fourth in showmanship. My trainer and I am very impressed with this product and now several of the show horses are on it . Thank you Steel Horse Formulations - Deborah Goldby, DVM
