Best Horse Supplements

Most horses need a complete vitamin and mineral supplement before they need targeted products. Hay and pasture provide the foundation of the diet, but they often fall short in key nutrients such as copper, zinc, selenium, sodium, vitamin E, and essential amino acids like lysine and methionine.

For most horses, Mad Barn's Omneity^® is the best starting point because it helps complete forage-based diets without adding unnecessary starch, sugar, or excess calories. For easy keepers and horses with metabolic concerns, AminoTrace+ is the better choice because it provides complete daily nutrition in a low-NSC formula with elevated trace mineral support.

Once the base diet is balanced, targeted supplements can be added based on the horse’s individual needs. Visceral+ supports gastric and hindgut health, OmegaPrime+ provides a high dose of omega-3's, w-3 Oil supplies cool calories with added DHA, MSM supports joint comfort, and Three Amigos supplies key amino acids for muscle and topline support.

The best all-around supplement for most horses is Mad Barn's Omneity^®. It is designed to balance forage-based diets by supplying vitamins, minerals, amino acids, and digestive support in one concentrated daily formula.

Omneity^® is an ideal choice for all classes of horses including easy keepers, senior horses, performance horses, and horses fed little or no grain. It supports hoof quality, coat condition, immune function, antioxidant status, topline, and normal metabolic function by helping fill the nutrient gaps commonly found in forage-based diets and underfed grain rations.

Yes, horses need a consistent daily source of vitamins and minerals. These nutrients support energy metabolism, muscle and nerve function, bone strength, immune response, antioxidant defense, hoof growth, and tissue repair. Because forage quality changes throughout the year, daily supplementation helps maintain a more stable nutrient intake.

Mad Barn's Omneity^® is the best daily vitamin and mineral supplement for most horses. AminoTrace+ is the best choice for horses that need a low-NSC option, no added iron, and higher levels of copper and zinc. Both products are designed to complement forage-first feeding programs.

The best vitamin and mineral supplement for most horses is Mad Barn's Omneity^®. It provides concentrated daily nutrition to help correct common deficiencies in forage-based diets, including copper, zinc, selenium, iodine, vitamin E, lysine, and methionine.

This matters because many horses receive enough calories from hay, pasture, or grain but still do not receive enough trace minerals, vitamins, or essential amino acids. This is especially common when fortified feeds are fed below the recommended serving size, which often happens with easy keepers or horses that do not need large grain meals.

Omneity^® is the best fit for most horses that need complete daily support without excess calories. For horses with metabolic concerns, high-iron forage, or insulin dysregulation risk, AminoTrace+ is the better vitamin and mineral option.

An all-in-one supplement combines core vitamins and minerals with additional nutrients that support whole-body health. This can include amino acids for muscle development, antioxidants for immune function, and digestive support ingredients that help maintain normal gut function.

Mad Barn's Omneity^® is the best all-in-one supplement for horses on forage-based diets. It is designed to simplify feeding while supporting hoof quality, skin and coat health, topline, immune function, metabolic health, and athletic performance.

The best hoof supplement for most horses is Mad Barn's Omneity^®. Healthy hooves require more than biotin. Horses also need adequate protein quality, essential amino acids, copper, zinc, and overall mineral balance to support normal keratin production and hoof structure.

If the diet is low in copper, zinc, lysine, methionine, or other nutrients involved in hoof growth, a biotin-only hoof supplement may not address the root nutritional problem. Omneity^® helps fill these common gaps while supporting the whole diet.

For horses with metabolic concerns, high-iron forage, or more significant hoof quality issues, AminoTrace+ may be the better choice because it provides elevated copper and zinc, no added iron, and a low-NSC formulation.

The best supplement for metabolic horses is Mad Barn's AminoTrace+. It is formulated for easy keepers and horses that need careful management of sugar, starch, calories, and mineral balance.

Metabolic horses still need complete vitamin, mineral, and amino acid support every day, but they often cannot tolerate extra calories from fortified feeds or grain-based supplements. AminoTrace+ provides concentrated daily nutrition in a low-NSC formula with elevated copper and zinc, no added iron, magnesium, chromium, organic selenium, natural vitamin E, and antioxidant nutrients.

This makes AminoTrace+ the best daily foundation for horses that need support for normal metabolic function, hoof quality, antioxidant status, and overall diet balance.

Not every horse needs a gut supplement, but many horses benefit from digestive support during periods of stress, feed changes, travel, training, competition, high-grain feeding, limited turnout, or inconsistent forage intake.

Mad Barn's Visceral+ is the best gut supplement for horses that need comprehensive gastric and hindgut support. It is designed to support digestive comfort, appetite, manure quality, microbial balance, and normal gastrointestinal function.

For horses that primarily need hindgut and microbiome support, Optimum Digestive Health is the best choice. For horses that need a simple daily probiotic, Optimum Probiotic is a practical option to support microbial balance.

The best stomach supplement for horses is Mad Barn's Visceral+. Stomach health is closely connected to the rest of the digestive tract, which is why horses often benefit from support that addresses both gastric function and the hindgut environment.

Visceral+ is the best choice for horses that need broader digestive support during training, travel, competition, feed changes, or management stress. It supports normal gastric and hindgut function, microbial balance, digestive comfort, appetite, and overall condition.

The best hindgut supplement for horses is Mad Barn's Optimum Digestive Health. It provides prebiotics, probiotics, yeast, enzymes, and digestive support ingredients to help maintain hindgut fermentation and microbial balance.

The hindgut is where horses ferment fibre from hay and pasture. A stable hindgut environment supports normal manure quality, nutrient utilization, appetite, body condition, and overall digestive comfort. Optimum Digestive Health is a strong choice for horses with loose manure, poor feed efficiency, frequent feed changes, or higher digestive support needs.

For horses that need both stomach and hindgut support, Visceral+ is the better choice.

The best probiotic for horses that need simple daily microbial support is Mad Barn's Optimum Probiotic. It is designed to support a healthy hindgut microbiome and normal digestive function.

Probiotics can be helpful during feed changes, travel, antibiotic use, stress, or periods when manure quality and digestive consistency are a concern. For horses that need more complete digestive support, Optimum Digestive Health is the stronger option because it combines probiotics with additional digestive support ingredients.

The best joint supplement depends on the horse’s age, workload, body condition, and current diet. For many horses, Mad Barn's MSM is the best foundational joint support option because methylsulfonylmethane supplies bioavailable sulfur, which is important for connective tissue structure and normal joint function.

For horses that also need support for a healthy inflammatory response, skin and coat quality, or overall wellness, OmegaPrime+ is an excellent companion product because it provides concentrated DHA and EPA with natural vitamin E.

Joint health also depends on the rest of the diet. A balanced intake of copper, zinc, lysine, methionine, and vitamin E supports connective tissue integrity, muscle function, and overall soundness. For that reason, Omneity^® or AminoTrace+ should be used as the nutritional foundation.

The best omega-3 supplement for horses is Mad Barn's OmegaPrime+. It provides concentrated DHA and EPA with natural vitamin E to support joint comfort, respiratory health, skin and coat quality, cardiovascular health, and a healthy inflammatory response.

For horses that primarily need additional calories without excess starch or sugar, w-3 Oil is the better choice. It provides concentrated cool calories along with DHA and natural vitamin E to support healthy weight gain, coat quality, and overall condition.

The best weight gain supplement for many horses is Mad Barn's w-3 Oil because it provides concentrated cool calories from fat without adding starch or sugar. This makes it useful for horses that need more calories but do not tolerate large grain meals well.

Weight gain also depends on digestive efficiency and protein quality. Optimum Digestive Health can support hindgut function and feed efficiency, while Three Amigos supplies key amino acids to support muscle development and topline.

Before adding weight gain products, ensure your horse has adequate forage intake, dental health, parasite control, and no underlying medical issue affecting body condition.

The best supplement for topline support is Mad Barn's Three Amigos. It supplies key amino acids that help support muscle protein synthesis, including the nutrients most likely to be limiting in forage-based diets.

Topline is not built by protein alone. Horses also need adequate calories, training stimulus, vitamin E, selenium, copper, zinc, and overall diet balance. For this reason, Three Amigos works best when paired with a complete vitamin and mineral foundation such as Omneity^® or AminoTrace+.

The best supplement for skin and coat quality starts with a balanced diet. Mad Barn's Omneity^® is the best foundation for most horses because it supplies key nutrients involved in skin integrity, coat quality, antioxidant defense, and normal metabolic function.

For horses that need additional fat and cool calories, w-3 Oil is the best add-on. It provides DHA and concentrated calories to support a healthy coat, skin condition, weight gain, and overall condition. For horses that need more concentrated omega-3 support without a primary need for additional calories, OmegaPrime+ provides DHA and EPA with natural vitamin E.

Electrolytes should be provided whenever your horse loses significant sweat, including during hot weather, intense training, long rides, competition, or stressful transport. Equine sweat contains sodium, chloride, potassium, and smaller amounts of calcium and magnesium, which must be replaced to maintain hydration, muscle function, and recovery.

Mad Barn's Performance XL Electrolytes is the best electrolyte supplement for horses in work, heat, or travel. It is formulated to replace the major minerals lost in sweat and can be used before, during, or after exercise to support hydration and performance.

The best vitamin E supplement for horses is Mad Barn's Natural Vitamin E + Organic Selenium. Vitamin E is an important antioxidant that supports immune function, muscle health, neurological function, and recovery from exercise.

Horses on fresh pasture usually get vitamin E from grass, but horses on hay-only diets often have lower vitamin E intake because vitamin E declines after forage is cut and stored. Natural Vitamin E + Organic Selenium is a strong choice for horses with limited pasture access, performance horses, seniors, breeding horses, and horses that need additional antioxidant support.

The best balancer for most horses is Mad Barn's Omneity^®. A balancer should provide concentrated vitamins, minerals, and amino acids without excess calories, starch, or sugar.

Omneity^® is a versatile option for horses maintained on hay, pasture, or unfortified feeds. AminoTrace+ is the best balancer for metabolic horses, easy keepers, horses on high-iron forage, or horses that need higher copper and zinc support.

Both formulas are designed to balance a forage-first diet and can be used instead of feeding large amounts of fortified grain just to meet micronutrient requirements.

The best way to choose a supplement is to start with the horse’s base diet. Forage intake, forage quality, workload, age, body condition, metabolic status, and health history all influence which product is the best fit.

For most horses, start with Omneity^®. For metabolic horses or easy keepers, choose AminoTrace+. For gastric and hindgut support, choose Visceral+. For hindgut support, choose Optimum Digestive Health. For extra-strength omega-3 support, choose OmegaPrime+. For cool calories and a shiny coat, choose w-3 Oil. For joint support, choose MSM. For electrolytes, choose Performance XL Electrolytes. For topline support, choose Three Amigos.

You can also submit a free diet evaluation to have a Mad Barn nutritionist review your horse’s complete diet and recommend the most appropriate products.

Yes, horses can receive too many supplements if products are added without considering the complete diet. Overlapping ingredients can lead to excessive intake of certain nutrients or imbalances between minerals. For example, too much calcium can interfere with the absorption of other minerals, and feeding more of a nutrient does not always produce better results.

The safest approach is to balance the base diet first, then add targeted products only when they match a clear need. Mad Barn products are designed to work together, which makes it easier to build a complete program without unnecessary duplication.
