Let’s take a look at some of the best joint supplements for horses on the market today and how these can really help your horse manage their joint health issues.

Most horses at some point or another will need to take joint supplements. It rarely matters whether they are a youngster or in their later years in life, and the type of work your horse takes part in is also not a deciding factor when it comes to joint pain. At Horse Reviews we’ve put together our favourite products currently available inot the Best Joint Supplements for Horses UK.

Unfortunately, horse’s joints are not built to last and the demands on their bodies can often be too much. Prevention is always better than cure, but it can be difficult to always determine immediately whether, in fact, your horse is struggling with arthritis or joint pain. It is often the case it becomes more noticeable over time, usually when it is too late.

Why Use a Joint Supplement

Joint supplements are a great solution to joint pain. They are designed to help your horse move much more easily and seeks to reduce the impacts of arthritis, joint pain, and lameness. Your horse must be able to move smoothly and feel comfortable with everyday movement.


Horse supplements help to support normal and healthy joint function and can be key in eliminating stiffness, which can be common during colder weather. Older horses can massively benefit from joint supplements, as they tend to feel the effects of ongoing injuries with age. However, younger horses can often suffer from their joints too particularly those at competition or in a heavier style of work.

Joint supplements can be purchased very easily from all equine stores and are also widely available online. Supplements aren’t always that cheap to buy and purchasing online can often generate some great deals that you won’t want to miss out on.

Our #1 product is a great addition to any horse, old or young and can be a good preventative measure when used alongside the right advice.

Best Ingredients in a Horse Joint Supplement

So what can be found in your horse’s joint supplements?

Choosing a joint supplement for your horse can be tricky. Many variations of ingredients exist within joint supplements and with so many different combinations of ingredients available, you may find that one type works much better for your horse than another. Combinations of ingredients usually work best and provide the most all-round relief. Always make sure you read the label of ingredients carefully so you are in the know about what you are administering to your horse.

With that being said, here are 5 of the very best ingredients you will most commonly find in horse joint supplements:


Glucosamine is an amino sugar that is found in many horse joint supplements. It aims to reduce arthritic pain and might help to decrease the frequency of joint injections your horse needs. Its lubricating properties act as a shock absorber which effectively cushions the joint during exercise. It is a fast-acting supplement that can relieve pain sometimes as quickly as 10-15 days.

Chondroitin Sulfate

Chondroitin Sulfate works hand in hand with Glucosamine and is classed as a glycosaminoglycan which helps to slow the breakdown of cartilage. The pain relief effects of using this ingredient are not so apparent as with Glucosamine, but when working together, they can not only provide effective pain relief from arthritic type symptoms but also delay the cartilage deterioration rate. These two are an absolute powerhouse when combined.

Hyaluronic Acid

Hyaluronic Acid is a very popular ingredient for reducing pain, heat, and joint swelling in horses. It is commonly used in joint supplements with both Glucosamine and Chondroitin Sulfate, but can also be purchased separately as either an oral tablet or in gel form. It is widely used for horses with injuries such as lacerations and abrasions thanks to its great wound healing properties.


Methyl Sulphonyl Methane, otherwise known as MSM works to reduce blood markers for oxidation and inflammation. It is particularly helpful for those equines suffering from chronic arthritis to manage pain and can be a good solution for aiding your horse to heal from an injury. It can also be highly beneficial for healthy skin, coat, and hooves and is often found in products that promote these types of health benefits.
