Does My Horse Need Joint Supplements?

Almost every adult horse can benefit from a joint supplement. Always consult with your veterinarian before adding a new supplement to your horse’s diet.

Today, joint supplements are often added to a horse's diet once the horse is already showing signs of stiffness, lameness, or other joint issues. However, if you provide a joint supplement early in your horse's life—before there are any joint-related issues—you can proactively support healthy joints and potentially prevent joint changes.

Horses with joint pain may have some of the following symptoms:

Lameness/limping
Pain during activity
Inflammation/swelling
Stiffness
Reduced or poor performance
Behavior changes while exercising, such as pinning ears or kicking out

Joint supplements for horses may help with:

Maintaining joint health
Arthritis
Athletic maintenance
Senior mobility
Soft tissue joint health
Following any type of joint surgery
Following a septic/infected joint

Best Ingredients for Horse Joint Supplements

There are several ingredients that may be found in joint supplements for horses. These ingredients include:

Glucosamine: This is one of the most common and well-known ingredients in joint supplements. It is considered the foundation for cartilage and joint fluid. Research suggests glucosamine can stimulate new cartilage production, inhibit cartilage breakdown, and stop inflammation in joints.
Chondroitin sulfate: This chemical is made naturally by chondrocytes (cells inside cartilage). Chondroitin sulfate also plays a part in inhibiting breakdown of cartilage, which can occur during inflammation.
Hyaluronic acid (HA): HA is used in horse joint supplements to help protect joints from normal stressors of exercise and daily life as a horse ages. It may also be used in cases of acute and chronic joint conditions by blocking inflammatory reactions and protecting the cells within the joint.
MSM (methylsulfonylmethane): MSM is a source of organic sulfur that plays a role in the formation of connective tissues that make up the joint such as bones, tendons, and ligaments.
Omega-3 fatty acids: Research for humans as well as dogs and cats has shown that the Omega-3 fatty acids EPA and DHA have anti-inflammatory effects and can be beneficial for joints. Recent research has found similar indications that Omega-3 would also benefit horses by reducing joint pain and inflammation.
