As they age, horse's joints deteriorate from injury, disease or regular wear-and-tear. Add a quality joint supplement to your horse's diet to reduce joint pain and retain mobility.
Glucosamine is a structural component of cartilage. As horses age, their bodies decrease the natural production of glucosamine, which causes cartilage disintegration between joints. Equine glucosamine supplements contain either pure glucosamine or isolated glucosamine from shellfish. Supplement labels show whether the active ingredient is glucosamine sulfate or glucosamine hydrochloride, and both types effectively regenerate new cartilage. The recommended effective dosage is around 6,000 milligrams per day for the average weight horse, and horses at work may need up to 10,000 milligrams per day.
- Owners see improvement in as little as 10 to 14 days
- No known side effects
- Safe for pregnant mares
- Best when it is used with chondroitin rather than alone
Like glucosamine, chondroitin is an essential element of cartilage by giving cartilage its elasticity and compression resistance. Dosage ranges from 1,250 milligrams per day for horses at rest to 5,000 milligrams per day for horses at work.
- Horses move less stiffly
- Reduces cartilage breakdown
- No known side effects
- Most effective when combined with glucosamine rather than used by itself
- Does not have the pain relieving effects of glucosamine
- Very few chondroitin-only supplements exist on the market
- Low absorption rate
Hyaluronic acid is an element of joint fluid. This was the first equine joint supplement and it started as a joint injection in the 1970s. Legend and Adequan are the name brands of injectable hyaluronic acid and are available only by prescription. However, owners can purchase oral gels or powder formulas over the counter. Oral gels cost more than powders but reduce joint swelling, heat and pain faster. Dosage is 100 milligrams per day, and this supplement works well when combined with glucosamine and chondroitin.
- Joint injections are extremely effective in reducing joint pain
- Oral hyaluronic acid gels effectively reduce joint heat, pain and swelling
- Visible improvement in as little as 48 hours with oral supplements
- Injections are expensive and available only by prescription
- Needles may damage joints if not administered properly
- Not effective in treating osteoarthritis symptoms
MSM is a sulfur-based anti-inflammatory that reduces joint inflammation and pain. Ron Riegel, DVM, performed a study on 30 racing Standardbreds by giving one group 10 grams (10,000 milligrams) of MSM, the second group 20 grams (20,000 milligrams) of MSM, and the third group nothing for eight weeks. He found that both dosages of MSM effectively reduced inflammation and soreness, but the group receiving 20 grams showed improvement faster. The horses also showed lower aspartate aminotransferase and creatine kinase in blood tests and improved their training times.
- No known side effects
- Effectively reduces joint inflammation
- Very absorbable
- Many combination joint supplements do not contain enough MSM to produce results
- Not approved for pregnant mares
Studies have shown that several herbal remedies work as effectively as non-steroidal anti-inflammatory medications. Devil's Claw is an herb that reduces inflammation, and many horse owners use it as an herbal alternative to phenylbutazone. Manufacturers often combine Devil's Claw with other herbs such as yucca, Boswellia and grape seed extract.
- Fewer side effects than phenylbutazone with similar anti-inflammatory results
- Effectively treats osteoarthritis symptoms and joint inflammation
