Equine Arthritis Supplements

Arthritis describes any condition which creates inflammation in the joints. The most common type of arthritis in horses is osteoarthritis, known as OA, which causes an erosion of the articular cartilage within the joint. It is estimated that nearly 60 percent of all equine lameness is related to OA. While there is no cure for arthritis, some feed supplements can help slow progression of the disease and provide relief from pain and inflammation.

  1. Glucosamine

    • The vast majority of equine supplements marketed for arthritis contain glucosamine. Because all supplements are classified as neutraceuticals, and therefore are not subject to FDA regulation, consumers should be aware that quality can vary widely from product to product.

      Glucosamine is a basic building block of the connective tissues and fluids within the joint. It is most effective as glucosamine sulfate 2KCl and glucosamine sulfate NaCl; the sulfur molecule is a carrier which improves absorption.

      Glucosamine normalizes cartilage metabolism, a process which is disrupted in the arthritic joint. Various studies on glucosamine suggest it is as effective as non-steroid anti-inflammatory drugs at relieving arthritic pain, with fewer side effects.

    Chondroitin

    • Chondroitin is a primary part of joint cartilage, but is limited as a feed supplement. An estimated 70 percent of ingested chondroitin passes through the system with being absorbed. Chondroitin is best utilized when fed in conjunction with glucosamine, as glucosamine aids in the absorption of the chondroitin within the body. Chondroitin inhibits the production of the enzymes associated with tissue destruction and inflammation in the joint.

    Cetyl Myristoleate

    • Cetyl myristoleate occurs naturally in sperm whales, mice and beavers. None of these animals develop arthritis. Cetyl myristoleate has limited clinical study history, but has shown significant improvements in treating arthritic conditions. To date, only a small number of products containing cetyl myristoleate are available for horses, and most also contain glucosamine.

    MSM

    • MSM is methylsulfonylmethane, a white, tasteless crystalline powder derived from DMSO (dimethyl sulfoxide). MSM offers many benefits to horses, including prevention of the development of arthritis, and a therapeutic effect on existing inflammation in arthritic joints. MSM is effective in small doses and has no side effects.
