Horses are susceptible to Osteoarthritis of the articular cartilage joints, especially competition horses. OA is caused by chronic repetitive trauma on the joints, with the exception of Septic Arthritis, that results from a systemic infection. Of course, prevention is better than cure.
Here we explore supplements for prevention of OA, and in future weeks, we will explore supplements that help with pain management of conditions like arthritis.

The effectiveness of a supplement depends on the individual horse and of course consistent administration. All the following supplements act as an anti-inflammatory but vary in the tissue they target.

Glucosamine and Chondroitin

While Glucosamine helps in the formation of cartilage and keep the joints lubricated for better movement and flexibility, thereby relieving the pain and swelling in the joints, Chondroitin Sulfate maintains the healthy cartilage and supports joint function in horses.

MSM Methylsulfonylmethane

MSM is a naturally occurring organosulfur compound.

To determine if oral MSM supplementation would alleviate exercise-induced oxidative stress (measured through markers in the blood), a study by the University of Madrid of twenty actively competing show jumpers concluded that MSM given over 7 days reduced oxidative stress and could play an important protective role of the joints in sport horses.

Hyaluronic Acid

Hyaluronic acid (HA) is found in joint cartilage and the lubricating synovial (joint capsule) fluid.

Hyaluronic acid is a major component of synovial fluid. In articular cartilage, hyaluronic acid coats each chondrocyte (cartilage cell), essentially giving it shock-absorbing properties.

Resveratrol

Researchers found that resveratrol prevented cartilage breakdown in laboratory animals with experimentally induced osteoarthritis. One study found horses consuming the supplement for four months were significantly less lame.

Fish Oil

Fish oil is a polyunsaturated fatty acid (PUFA) derived from cold-water oily fish such as mackerel or herring.

Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are the two fatty acids found in fish oil, have known anti-inflammatory properties and increase collagen.

Studies have indicated that the supplement has chondroprotective properties in healthy joints with mild synovitis.

Green Lipped Mussel Extract

The New Zealand green-lipped mussel (Perna canaliculus) is a large shellfish that thrives in that country.

Green-lipped mussel extract is another PUFA that’s naturally high in omega-3 fatty acids. Although its exact mode of action is not known, researchers believe the extract has anti-inflammatory properties.

Oral supplementation of marine-based DHA and EPA has been shown to reduce joint inflammation and improve lameness grade, hind-limb flexion responses, and ease of movement. Horses that received a unique, green-lipped mussel extract orally for 56 days had significantly reduced lameness severity, improved joint flexion test responses, and reduced joint pain.

To ensure proper mineral supplementation, it is recommended to first consult with a veterinarian or equine nutritionist who can assess the horse’s individual needs and recommend an appropriate balanced diet or mineral supplementation plan.

Horses require a variety of minerals for their overall health and well-being. Here are some important minerals that should be included in a horse’s diet:

Calcium

Calcium is essential for the development and maintenance of strong bones, teeth, and proper muscle function. It is crucial for horses of all ages, particularly growing foals and lactating mares.

Phosphorus

Phosphorus works in conjunction with calcium and is also important for bone development and maintenance. The ratio of calcium to phosphorus should be balanced in a horse’s diet to ensure proper absorption and utilization.

Magnesium

Magnesium plays a vital role in nerve and muscle function, as well as energy metabolism. It is necessary for overall muscle relaxation and can have a calming effect on horses.

Potassium

Potassium is an electrolyte mineral that helps regulate fluid balance, nerve function, and muscle contractions. Horses in work or living in hot climates may have increased potassium requirements.

Sodium and Chloride

Sodium and chloride are also electrolytes that play a role in fluid balance, nerve function, and maintaining proper hydration. They are often provided in the form of salt or salt blocks.

Iron, Copper, Zinc, and Selenium

These minerals are essential trace elements that horses require in small amounts. They play various roles in metabolism, enzyme function, immune system function, and antioxidant activity.

However, it’s important not to exceed the recommended levels of these trace minerals, as excessive amounts can be toxic.

It’s worth noting that the specific mineral requirements of a horse can vary depending on factors such as age, reproductive status, activity level, and overall health.

The minerals in a horses diet are influenced by soil and water, as well as farming techniques.

To ensure proper mineral supplementation, it is recommended to consult with a veterinarian or equine nutritionist who can assess the horse’s individual needs and recommend an appropriate balanced diet or mineral supplementation plan.

We recommend a HTMA to assess a horses mineral status.
