Arthritis refers to the inflammation in the joint, there are many different types of arthritis ranging in severity. Although arthritis is more prevalent in older horses, horses of any age can still be affected especially those that have been competing at a high level from a young age. The effects of arthritis are irreversible, but research has shown that supplements can be used as a preventative measure.

One of the most talked-about types of arthritis is osteoarthritis, which is a chronic and progressive deterioration of the horse’s joint cartilage (the protection of bones inside the horse’s joints). Young, growing horses (under 1 year of age) can suffer from a form of arthritis where the immature joint cartilage separates from the bone allowing fluid to enter the space. This can also cause cysts to form under the cartilage. This can be caused by rapid growth and disproportionate levels of copper and zinc in the diet.
