When selecting a joint supplement for a senior horse, the most important consideration is the presence of proven ingredients like glucosamine, chondroitin, MSM, and hyaluronic acid at therapeutic levels, along with anti-inflammatories such as devil’s claw or boswellia. Our editorial team researched top-rated supplements specifically formulated for older horses, factoring in their unique digestive sensitivities, reduced mobility, and potential for arthritis or laminitis.

Senior horses often have decreased nutrient absorption and may be on special diets for Cushing’s or insulin resistance, so we prioritized supplements with gentle coatings, no added sugars, and palatable flavors. Each pick below was chosen for its targeted support of joint health while accommodating the common health challenges of aging equines.
