The best joint supplements for older horses provide additional nutritional support for normal and healthy joint function to help keep them in good working order, comfortable and moving at their best, enabling your horse to live a full and active life. Throughout your horse’s life, his musculoskeletal system and joints will be put to the test – and there’s a lot for your horse’s joints to contend with throughout the year.
In the winter, the increased likelihood of restricted turnout means they’re likely to be moving less and when this is combined with colder temperatures, stiffness is a common result. If the ground’s not hard then it’s wet, which can lead to more roadwork and increased concussive forces on the joint, too. Whereas in the summer hard ground is also unavoidable if you’re not confined to a school. Even if your horse is retired and able to live out full time, his joints – and the rest of his body – will require more support to maintain a good condition.

Best joint supplements for older horses: what are your options?
Here is a selection of the best joint supplements for older horses that are currently available, including the manufacturers’ descriptions of their products…
NB: Cost per day has been calculated using the maintenance measure for a 500kg horse in light work (where there was variation) and the RRP of the smallest available tub. Some products require you to feed more with a higher workload, which will increase the cost per daily measure, while buying a larger tub will likely decrease it – these costs per day are a guide only.

How to choose the best joint supplement for older horses
Joint supplements that are formulated specifically for older horses will tend to have the highest specification in a manufacturer’s joint supplement range – higher than most in our guide to the best joint supplements for general use.
Joint supplements are available in liquid, powder, and pellet forms, and it’s important to choose a form that your horse will readily consume. Cost is another consideration, and it’s often more economical to purchase larger quantities. We’ve calculated the daily cost of all the supplements featured in this guide using the smallest tubs available to help you compare them easily.
The most common ingredients found in joint supplements typically include glucosamine, MSM (methyl sulphonyl methane), and HA (hyaluronic acid), which support cartilage, suggested anti-inflammatory properties, and aid lubrication.
