Regardless of your experience, if you’re a new horse owner or one who dealt with a whole herd of horses before, you surely want your animal to stay healthy. Unfortunately, horses get older, and just like humans, the older they get the bigger the chances that they will experience joint pains and other problems with the motor system, which can lead to lameness.

Thankfully, owners can relieve their horses a bit by giving them supplements that significantly improve the condition and mobility of joints. There are many joint supplements available on the market, but not all products are going to be good and effective.

What to look for when choosing a supplement for horse joints?

  • Glucosamine – is responsible for the reconstruction of cartilage. It has a significant impact on the flexibility and mobility of a horse’s joints. It also cares for joints and replenishes synovial fluid. Glucosamine is also a natural painkiller.
  • Chondroitin – can be found in cartilage, bones and connective tissue. By using it regularly, it can reduce the risk of a horse’s cartilage sustaining any damage.
  • Hyaluronic acid – lubricates the synovial membranes and has a positive effect on the condition of the cartilage. It also helps the body reduce any swelling and supports its healing response. This supplement gives the best results when given in the form of a gel, however, it can also be given orally. 
  • Vitamin C – removes free radicals and inflammation which are dangerous to connective tissue. It’s important to follow the dosage recommendations because an overdose can harm cartilage.
  • Herbs – have anti-inflammatory properties, strengthen a horse’s immune system, and effectively help with arthritis as well as other accompanying diseases.

Frequently Asked Questions (FAQ)

Are joint supplements good for horses?

When choosing a joint supplement for your horse, it’s crucial to identify the horse’s age, type of training and physical condition. Young horses will need a product that will regulate the development of the cartilage skeletal system and joints. Horses in extensive training need a supplement that will help them maintain good joint mobility and ensure joint regeneration. Senior horses and horses after an injury will require yet another supplement. Therefore, it’s so important to choose a product for a specific problem.

When do horses need to be given joint supplements?

It’s worth remembering that prevention is better than cure. So, if you notice that your horse feels any pain while moving, then don’t hesitate and start treatment with a good joint supplement right away.

Even if your horse doesn’t currently have any joint problems, then you can provide him with basic treatment, e.g., with hyaluronic acid, to prevent deficiencies.
