Horse supplements by ingredient make it easier to find nutritional products tailored to your horse’s individual needs. Explore our carefully selected range of supplements containing electrolytes, glucosamine, magnesium, and probiotics. Each ingredient has a specific nutritional purpose, from replacing minerals lost through sweating to supporting normal muscle function, joint health, and intestinal microbiota. Browse our ingredient categories and select the most appropriate supplement based on its composition, your horse’s daily diet, and individual nutritional requirements.
Horse supplements by ingredient
Nutritional supplements for horses contain a wide variety of ingredients, each with a specific role in supporting normal physiological functions. Certain nutrients are essential for muscle and nerve function, while other ingredients are used to support joint health, intestinal microbiota, or fluid and electrolyte balance.
Searching for horse supplements by ingredient allows you to compare products more effectively and identify formulations that match your horse’s individual nutritional requirements.
At Sportpaardenarts.nl, we offer a carefully selected range of supplements for recreational and performance horses, with particular attention to ingredient quality, product composition, and nutritional applications.

Electrolytes for horses
Electrolytes are essential minerals involved in maintaining fluid balance, nerve conduction, and normal muscle function. When horses sweat, they lose considerable amounts of sodium, chloride, and potassium, along with smaller quantities of other minerals.
During intensive exercise, prolonged transportation, or hot weather, electrolyte supplementation can help replace these losses. Electrolyte management is particularly important for performance horses that sweat heavily or regularly undergo prolonged physical exertion.

Glucosamine for horses
Glucosamine is a naturally occurring compound involved in the synthesis of glycosaminoglycans, which are important structural components of cartilage and other connective tissues.
Glucosamine is frequently included in joint supplements for horses, often combined with chondroitin, MSM, or other ingredients intended to support the musculoskeletal system.
These supplements may be of interest to owners seeking nutritional support for the joints of performance horses or older horses. However, scientific evidence demonstrating clinically meaningful benefits from oral glucosamine supplementation in horses remains limited.
Magnesium for horses
Magnesium is an essential mineral involved in hundreds of enzymatic reactions. It plays an important role in normal muscle function, nerve conduction, and energy metabolism.
Horses obtain magnesium primarily from forage and other dietary ingredients. When the daily diet does not provide sufficient magnesium, targeted supplementation may be beneficial.
Magnesium is also frequently included in supplements intended for nervous or excitable horses. However, it is important to distinguish magnesium’s essential physiological functions from the expectation that additional magnesium will automatically produce a calming effect. In horses with adequate magnesium intake, such an effect has not been convincingly demonstrated.
Probiotics for horses
A balanced intestinal microbiota is essential for normal digestive function in horses. In the cecum and large intestine, microorganisms ferment dietary fiber, producing volatile fatty acids that provide an important source of energy.
Probiotics contain live microorganisms that may support normal intestinal function, depending on the specific microbial strain and formulation. Certain live yeast cultures are among the microorganisms used in equine nutritional supplements.
Some products also contain prebiotics: dietary ingredients that support the activity of selected intestinal microorganisms.
Supplements containing prebiotics and probiotics may be particularly interesting during dietary changes, intensive training periods, or whenever additional nutritional support for intestinal microbiota is desirable.
How do you choose the right supplement for your horse?
The presence of a particular ingredient does not necessarily determine whether a supplement is suitable for your horse. Its concentration, chemical form, bioavailability, and combination with other nutrients are equally important.
When comparing supplements, consider the following:
- Purpose of supplementation: Which physiological function are you aiming to support?
- Existing diet: Which nutrients does your horse already receive through forage, concentrate feeds, and other supplements?
- Product composition: Which ingredients are included, and in what quantities?
- Individual requirements: How do your horse’s age, training workload, health status, and body condition affect its nutritional needs?
A supplement containing multiple ingredients is not automatically more effective than a product containing a single, carefully selected nutrient. The most appropriate formulation depends on your horse’s actual requirements.
Supplements by ingredient or by indication?
At Sportpaardenarts.nl, you can explore nutritional supplements in two different ways.
Through supplements by ingredient, you can find products based on specific ingredients such as magnesium, glucosamine, electrolytes, or probiotics.
Through products by indication, you can browse supplements according to their intended application, including muscle function, joint health, digestive health, respiratory health, and athletic performance.
Both approaches complement each other and help you identify nutritional products that best suit your horse’s individual needs.
Advice from the equine veterinarian
As a veterinarian specializing in equine sports medicine, I recommend assessing your horse’s nutritional requirements before selecting a supplement.
In performance horses, I pay particular attention to electrolyte losses through sweating, adequate essential mineral intake, and the relationship between nutrition, muscle function, and digestive health.
Choose supplements based not only on their main ingredients but also on dosage, formulation, and potential overlap with other products. When a nutritional deficiency is suspected or health problems persist, I recommend a complete dietary evaluation and, where appropriate, further veterinary investigation.
