Joint supplements for horses provide additional nutritional support for normal and healthy joint function to help keep them comfortable and moving at his best. 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 he’s 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.
Common ingredients found in joint supplements for horses include:
- MSM (methyl sulphonyl methane)
- HA (hyaluronic acid)
If you compete with your horse then it is important you make sure any supplements you use do not contain any prohibited substances.
Joint supplements for horses: what are your options?
Here is a selection of the best joint supplements for horses that are currently available below in our alphabetical list, which includes 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.
