Best Horse Supplements
Discover Mad Barn’s range of high-quality equine supplements, expertly formulated to balance your horse’s diet and support overall health, performance, and more.
Selecting the Right Supplements for Your Horse
Every feeding program should start with a balanced, forage-first diet that meets your horse’s vitamin, mineral, and amino acid requirements. While forage typically supplies most of a horse’s energy and protein, hay and pasture often lack adequate amounts of essential micronutrients such as copper, zinc, selenium, vitamin E, sodium, and lysine. These nutrients are essential for maintaining hoof health, supporting immune function, optimizing athletic performance, and promoting overall health and soundness.
To address these nutrient gaps, start with a complete vitamin and mineral supplement as the foundation of your horse’s feeding program. This ensures daily requirements are met and provides a foundation on which to build the rest of the diet.
At Mad Barn, our nutritional supplements are formulated to balance a forage-first diet by supplying the vitamins, minerals, and amino acids your horse requires to meet daily nutrient needs. We use premium, research-backed ingredients to ensure optimal bioavailability and support every aspect of your horse’s health and performance.
Once your horse’s diet is balanced, choose from our targeted supplements for gut health, respiratory function, joint support, mood balance, and more. Each product is scientifically formulated with high-quality ingredients to address specific needs and keep your horse performing at their best.

Most horses benefit from a complete vitamin and mineral supplement to fill common gaps in forage-based diets. Hay and pasture are often lacking in essential nutrients such as copper, zinc, selenium, sodium, and essential amino acids like lysine. Horses on hay-only diets will also have low vitamin E intake. Providing these nutrients daily supports hoof quality, coat health, immune function, metabolic health, and overall performance.
Additional supplements may be needed based on age, workload, health status, or specific goals, such as supporting gut function, joint health, or muscle recovery. Omneity® and AminoTrace+ are popular choices to cover daily nutrient needs.
Yes, horses need a source of vitamins and minerals in their diet every day. These nutrients play essential roles in nearly every physiological process, including energy metabolism, muscle and nerve function, bone strength, immune response, and antioxidant defense. Because most vitamins and minerals are not stored in large reserves in the body, they must be supplied daily through the diet. Missing days can result in inconsistent intake and reduce the effectiveness of supplementation.
A complete vitamin and mineral formula like Omneity® or AminoTrace+ ensures your horse consistently meets daily requirements, even when forage quality changes throughout the year.
An all-in-one supplement combines a complete vitamin and mineral formula with additional ingredients to support other aspects of health, such as amino acids for muscle development, probiotics for digestion, and antioxidants for immune function. This approach simplifies feeding by reducing the number of separate products needed while ensuring nutritional balance.
Omneity® is Mad Barn’s all-in-one supplement designed to meet the needs of horses on forage-based diets. Feeding Omneity® supports hoof health, skin and coat quality, immune function, metabolic health, and athletic performance.
Not all horses require a gut supplement, but they can be beneficial in situations where digestive health is compromised or at higher risk. Horses with a history of digestive upset, changes in feed, high-grain diets, travel stress, or limited turnout may benefit from probiotics, prebiotics, and ingredients that support hindgut fermentation.
Options like Visceral+ and Optimum Digestive Health provide comprehensive support for the gastrointestinal system.
The best joint supplement provides ingredients that support cartilage health, synovial fluid production, and a healthy inflammatory response. Commonly researched ingredients include methylsulfonylmethane (MSM) and omega-3 fatty acids, such as DHA found in w-3 Oil. Joint health also depends on a balanced diet that supplies adequate zinc, copper, lysine, and vitamin E, which play key roles in connective tissue integrity, muscle function, and overall soundness.
The best way to choose a supplement is to evaluate your horse’s current diet and identify any nutritional gaps. Working with an equine nutritionist to conduct a forage analysis or a free diet evaluation can determine whether your horse is meeting requirements for vitamins, minerals, amino acids, and other key nutrients.
Once the core diet is balanced, you can add targeted supplements to address specific goals such as joint support, gut health, hoof quality, or metabolic balance. For example, Omneity® provides complete vitamin and mineral support, Visceral+ supports gut health, and w-3 Oil supplies omega-3 fatty acids for joint, skin, and cardiovascular health.
Electrolytes should be provided whenever your horse loses significant amounts of sweat, such as during hot weather, intense training, long rides, or stressful transport. Sweat contains sodium, chloride, potassium, and smaller amounts of calcium and magnesium, all of which need to be replaced to maintain hydration and muscle function.
Products like Performance XL Electrolytes are formulated to replace the mineral losses in equine sweat and can be used before, during, and after exercise to support recovery and performance.
Weight gain supplements should provide concentrated calories in a form that is easy to digest, without causing digestive upset. Fat-based supplements such as w-3 Oil deliver cool calories and the omega-3 fatty acid DHA, while products that support hindgut health, like Optimum Digestive Health, help improve nutrient absorption and feed efficiency.
Before adding weight gain products, ensure your horse’s diet provides adequate protein and that they are free of underlying health issues that could be affecting body condition.
A balancer is a concentrated supplement that provides vitamins, minerals, and amino acids without excess calories. The best balancer depends on your horse’s specific needs and forage type. Omneity® is a versatile option for most horses, while AminoTrace+ is designed for horses with metabolic concerns or higher trace mineral requirements.
Both formulas are made to balance a forage-first diet and can be fed alongside hay, pasture, or an unfortified base feed.
Yes, over-supplementation can lead to imbalances or excessive intake of certain nutrients, which in some cases can be harmful. For example, too much calcium can interfere with the absorption of other minerals, and feeding more than 20 mg of biotin per day has not been shown to provide additional benefits. Duplicating ingredients across multiple products is a common cause of oversupply.
Mad Barn's products are designed to work together so you can safely combine multiple products. If you are concerned about your horse’s total intake or want extra reassurance, you can submit a free diet evaluation to have our nutritionists review the complete diet.
