This handy guide lets you know the what, when, how, and why of feeding your horse joint supplements.

Picture this: you just bought a new horse and the shopping list for your favorite four-legged friend is already a mile long. It includes everything from blankets and brushes to salt licks and stall plates. But there is something more important that you may not have thought to add to the list: a joint supplement.

What are Joint Supplements for Horses?

Joint supplements are daily formulas designed to help ensure that horses have a steady supply of the key ingredients they need to maintain healthy joints. Some of the fundamental ingredients to look for in horse joint supplements include collagen, glucosamine, chondroitin sulfate, hyaluronic acid, and MSM.

Does My Horse Need a Joint Supplement?

You may be thinking, but you don’t even know my horse. How do you know he needs a joint supplement? In return, we’ve got a question for you: do any of the following phrases describe your horse? Young horse, horse in light work, horse in heavy work, performance horse, horse in recovery, or a senior horse? If so, your horse may be at risk for osteoarthritis, because arthritic changes have been found in all these types of horses.

That’s right, osteoarthritis can happen in any horse! Healthy joints are key to your horse’s success (and happiness)! A 1999 study in the Equine Veterinary Journal found arthritic changes in a herd of wild mustangs [1], which led the researchers to conclude that osteoarthritis (also known as Degenerative Joint Disease [DJD] or simply “arthritis”) is a natural part of the aging process for horses, even if they don’t spend their lives in heavy work.

Since all horses are at risk for developing arthritis, providing proactive support is a smart choice for riders who have horses of any age and workload.

Are Horse Joint Supplements Effective?

When it comes to the question of whether joint supplements work, there are several studies that show benefits to joint health from the oral supplementation of key ingredients.

In a 28-day study at Texas A&M University, SmartPak’s joint supplement SmartStride Ultra was shown to significantly increase the range of motion in the hock at the walk and tended to increase range of motion in the hock at the trot. This comprehensive formula includes turmeric and resveratrol to support a normal response to inflammation; glucosamine, chondroitin sulfate, and hyaluronic acid (HA) for joint health; collagen and silica for resilient tendons and ligaments.

One study supported the use of oral HA to reduce joint swelling after surgery to remove an OCD in the hock [2]. In the study, 48 young horses underwent arthroscopic surgery to correct OCD lesions in the hock with half receiving an oral HA gel and half serving as controls. The horses that were supplemented orally with HA had less swelling of the hock joint after surgery than those that didn’t.

An eight-year study demonstrated that consistent use of an oral glucosamine and chondroitin supplement resulted in a decreased need for hock joint injections to maintain soundness in a group of show hunters/jumpers [3]. Or, in non-vet speak, the supplement helped keep the joint structures healthy enough that the horses required fewer joint injections.

Finally, a group of researchers in Europe showed that MSM exerts a protective effect on oxidative and inflammatory exercise induced injury in the horse [4]. In layman’s terms, that means that MSM has been shown to help reduce the wear and tear of joint tissues caused by exercise.

This video answers a question about feeding joint supplements, their efficacy, bioavailability (if your horse can absorb the ingredients), and safety. SmartPaker Sarah and Dr. Gray discuss a number of equine clinical studies focused on feeding joint supplements and their results.

When is the Best Time to Start My Horse on a Joint Supplement?

Now! Joint supplements contain ingredients such as glucosamine, chondroitin sulfate, and hyaluronic acid and are used to help keep joints healthy and avoid future problems. This means that the best time to start a joint supplement is actually before your horse starts to show signs of joint pain and discomfort.

For your senior horse, it’s not too late for him to benefit from a joint supplement! If your older horse is showing signs of discomfort, giving a joint supplement will be a smart choice as it can help ensure your golden oldie has a steady supply of the ingredients he needs to cope with the stress on his aging joints.

How to Shop for Horse Joint Supplements

When it comes to shopping for a joint supplement, there are many options to choose from. While this can seem overwhelming, it also means that there’s a perfect supplement out there to fit your horse’s exact situation! Next, let’s walk through the different categories of joint supplements, factors to consider when selecting a formula, and ingredients to look out for depending on your horse’s needs.

Types of Joint Supplements for Horses

There are three main categories of joint supplements:

• General – provides ingredients to support overall joint and cartilage health.
• Senior – includes ingredients to help address discomfort associated with aging.
• Rehabilitation – has an emphasis on supporting the normal rehabilitation process.

How to Choose a Joint Supplement for Your Horse

When considering what joint supplement to give your horse, it will be helpful to know what level of workload he is in and the goal of supplementing.

While we will discuss common ingredients and amounts given in supplements based on your horse’s workload, keep in mind that you can slide your horse up or down these above levels based on a variety of factors including their age, health history, or your budget.

Amounts of Key Ingredients to Shop For

• Glucosamine – For horses in light to moderate work 2,000 – 7,500 mg is generally considered appropriate, while this may increase to up to 12,000 mg for horses in very heavy work.
• Chondroitin – Joint supplements most often contain between 1,000 – 2,000 mg of chondroitin. Research has shown that, while providing chondroitin may be helpful for joint health, providing higher levels of it may not mean additional support.
• Hyaluronic Acid (HA) – Joint supplements generally offer HA with amounts ranging from 25 mg for horses in moderate work to around 150 mg for those who may benefit from additional support.
• MSM – Ranges from 5,000 – 12,000 mg depending on how much support the supplement is designed to provide.
• Turmeric – It can be purchased on its own for antioxidant support, or turmeric can be found in certain joint support formulas designed for horses in moderate to very heavy work. You’ll generally find 5,000 – 10,000 mg of turmeric powder in joint supplements.
• Resveratrol – About 300 – 1,000 mg of resveratrol is common for joint support.
• Collagen – 1,000 mg of collagen offers basic support while higher levels from 4,000 – 15,000 mg may be a better choice if your horse is dealing with particular issues.
• Silica – You’ll generally find between 250 -300 mg of silica in joint and tendon and ligament products.

How to Shop for Senior Horse Joint Supplements

While the name may imply they’re only for senior horses, these supplements may be ideal for adult horses of any age that are dealing with discomfort from exercise or aging. Senior joint supplements for horses focus on ingredients that maintain comfort and support a normal response to inflammation. Look for these ingredient amounts in products for your older horse:

• Boswellia – Keep an eye out for 100 – 1,000 mg of boswellia if your horse may benefit from this ingredient’s support.
• Devil’s Claw – Generally, 1,000 – 2,500 mg of devil’s claw is in senior support products.
• Turmeric and Resveratrol – May also be particularly helpful for horses dealing with discomfort from aging or exercise.

How to Shop for Recovery Joint Supplements

For horses who are rehabbing from injury, specific ingredients may help support the normal recovery process. Rehabilitation supplements provide joint support with tried-and-true ingredients, like MSM, while also being chock-full of antioxidants and herbs, such as yucca and vitamin C, to support the recovery process.

These formulas help minimize inflammation associated with normal healing while better managing discomfort. If your horse is actively recovering from an injury, it’s important to work closely with your veterinarian to determine the ideal supplement program. Therefore, we’d recommend that you talk to your vet about the below-listed ingredients and amounts before choosing a supplement for your recovering horse.

• Tendon and ligament support is important if your horse is dealing with issues in this area. Collagen and silica can be ideal ingredients to keep an eye out for to help maintain soft tissue health.
• Antioxidants, like turmeric, resveratrol, and MSM, can play a vital role in supporting a healthy recovery as they help to address cell stress and support normal cell health.
• Herbs, like yucca, devil’s claw and boswellia, may help support a normal response to inflammation and address excess discomfort.

What to Expect When Feeding Your Horse Joint Supplements

While you can’t see inside your horse’s joints, you can rest assured knowing that he’s getting a steady supply of the ingredients his body needs to help support his joints as he works.

If your horse generally looked and felt good when you started him on his joint supplement, you can sleep well knowing you’re providing proactive support for his long-term comfort and joint health. If your horse occasionally showed signs of stiffness or discomfort, we recommend providing the supplement for 4-8 weeks to determine if it provides the support you were hoping for/the support he needs. It’s always important to work with your veterinarian to determine which supplement is best for your horse’s unique needs.
