MSM for your horse: Everything you need to know about the natural supplement
As a horse owner, you want the best for your horse's health. In doing so, you may have come across MSM, which stands for methylsulfonylmethane – a natural sulfur and essential mineral that has become increasingly established in the equestrian world as a valuable supplement. MSM can support your horse’s joints, muscles, and even ligaments, relieve inflammation, and promote overall well-being. But what exactly is behind MSM, how does this mineral work, and why can it be so beneficial for your horse?
In this article, we dive into the details and shed light on how you can use methylsulfonylmethane correctly to optimally promote your horse's health.

What is MSM and why is it important for horses?
MSM is an organic sulfur compound found in plants, some foods, and the bodies of many animals. Sulfur is an essential building block for many structures and processes in the body: among other things, it is responsible for the formation of collagen and keratin, two important proteins for connective tissue, skin, and hooves. Enzymes and hormones also require sulfur to function optimally. Sulfur is therefore a central component for the health of your horse's entire organism.
A horse normally consumes sulfur through its feed, although some horses in certain life stages or under high physical strain can benefit from additional sulfur intake. An older horse or one that is active in sports, in particular, has an increased need for sulfur because the joints and muscles are under greater strain. This is where MSM can be a targeted and simple way to meet this need.
The main benefits of MSM for your horse
1. Supporting joints, tendons, and preventing joint problems
One of the best-known and most important areas of application for MSM is supporting the health of joints and tendons. It has anti-inflammatory properties and can therefore alleviate the symptoms of joint inflammation, arthritis, or osteoarthritis. Especially in older horses or those suffering from chronic joint and tendon problems, MSM can help promote mobility and reduce pain.
Since MSM has an anti-inflammatory effect, it can also be useful as a preventative measure – especially for horses that are trained regularly or have to perform at a high level in sports. With regular MSM supplementation, you can not only strengthen your horse's joints but also increase the resilience of the tendons. This is particularly valuable, as they are especially vulnerable under intense strain. Thanks to MSM, your horse remains optimally protected and supported during training or competition.
2. Promoting muscle function, ligaments, and accelerated regeneration
Sulfur plays a crucial role in muscle metabolism and is particularly important for the recovery of muscles, ligaments, and tendons after intense training sessions. MSM supports your horse's body in reducing muscle tension and repairing damage to muscles and ligaments. The ligaments, in particular, which are often subjected to high levels of stress and are closely linked to muscle work, benefit from the anti-inflammatory effect of methylsulfonylmethane.
For horses that are trained regularly or participate in competitions, MSM can therefore make a noticeable difference in regeneration. Horses that receive MSM regularly often show improved mobility and less muscle soreness after strenuous sessions. The natural sulfur compound strengthens the muscles in a targeted manner and helps to maintain or even increase your horse's performance.
3. Promoting healthy skin and stable hooves
The sulfur compound MSM is an important component of keratin, the protein that makes up hooves and skin. Through additional MSM intake, the hoof growth of your horse can be promoted – especially if it is prone to brittle hooves or has soft horn. The skin can also benefit from intake, as MSM contributes to better skin structure and resilience.
For horses that have skin problems or brittle hooves in particular, an additional dose of MSM is worthwhile. Through better sulfur supply, you can help your horse develop more resilient hooves and a healthy skin structure.
4. Supporting the immune system
In addition to structural benefits, MSM also has a positive effect on the immune system. It helps the body break down toxins and thus supports detoxification processes. As a result, it can strengthen your horse's resilience and promote its general health. Especially in times of high stress, such as during training, coat changes, or stressful situations, MSM can contribute to keeping your horse fit and healthy.
A well-functioning immune system is enormously important for the overall health of your horse. If you use MSM as a supplement, this can provide your horse with additional protection during stressful times and promote its recovery.
When is MSM supplementation particularly useful?
MSM is generally a safe and well-tolerated supplement for a horse, and in many situations, it can have a positive effect on your horse's health. MSM is particularly recommended for:
-
Older horses: As age increases, so does susceptibility to joint issues and inflammation. MSM can help maintain mobility and alleviate age-related complaints.
-
Sport and tournament horses: If your horse is trained regularly or participates in competitions, MSM can provide extra support for its joints and muscles.
-
Horses with joint and skin problems: For horses prone to inflammation, skin issues, or brittle hooves, MSM can improve vitality and resilience.
-
Horses in the recovery phase: MSM can accelerate regeneration and is therefore particularly useful after injuries or illness.
However, please note that MSM does not replace medical treatment. For chronic or acute conditions, you should always consult your veterinarian first before mixing MSM into the feed as a supplement.
Dosage and application: How do you administer MSM?
The recommended daily dose of MSM depends on your horse's weight and its specific needs. For an average-sized horse (500-600 kg), the daily dose is usually around 10-20 grams. It is often recommended to start with a higher initial dose (e.g., 20 grams per day) and reduce it to a maintenance dose after a few weeks.
MSM is available in various forms, usually as a powder that is simply sprinkled over the feed. A horse will generally accept it without any problems. If your horse is picky, you can mix the MSM with a little applesauce or molasses to make it more palatable.
What should you look for when buying MSM?
When buying MSM, quality is essential. Pure MSM should be free from additives, preservatives, or other impurities. High-quality products are often produced by distillation, a method that guarantees a pure and concentrated final product. When buying, look for certifications or tests that verify the purity of the product.
Storage is also important: MSM should be stored in a cool, dry place to maintain its effectiveness.
Conclusion: MSM as a valuable support for your horse
MSM, a natural sulfur compound, is a versatile and well-tolerated supplement that benefits your horse in many ways. Whether for supporting joints, promoting muscles, or improving skin and hooves – this sulfur substance offers numerous benefits and can strengthen the health and vitality of your horse in the long term.
However, it is important to use MSM responsibly and not to view it as a substitute for medical treatment. If you are unsure whether adding sulfur in the form of MSM is suitable for your horse, it is best to discuss it with your veterinarian.
