Omneity® is Mad Barn’s all-in-one vitamin and mineral supplement designed to help horses address their complete nutritional requirements by filling common gaps in forage- and grain-based diets.

Many horses get enough energy and protein in their diet, but lack key vitamins, minerals, amino acids, and other nutrients that are necessary to support normal physiological function. Without these nutrients, horses can experience hoof problems, skin and coat issues, poor performance, impaired muscle development, and other concerns.

Horses on forage-only diets require supplemental vitamins and minerals to balance nutrients that forage does not provide in adequate amounts. But even horses on underfortified grain rations often need supplementation to prevent deficiencies.

Omneity® is ideal as a ration-balancing supplement because it is highly concentrated, providing essential nutrients without adding significant calories or bulk to the diet. One formula can also replace multiple products including hoof, coat, and other targeted supplements, saving horse owners time and money in the feed room.

Omneity® combines high-quality organic trace minerals, vitamins, amino acids, antioxidants, biotin, digestive enzymes, and live yeast culture to support the horse’s overall needs in one comprehensive daily supplement.

Why Horses Need a Vitamin & Mineral Supplement

Forage should be the foundation of every horse’s diet. Hay and pasture provide fiber, support normal hindgut fermentation, and help meet energy and protein needs.

But forage alone will not provide a complete nutrient profile for horses. Gaps are common in forage-based feeding programs because hay and pasture vary in nutrient content depending on environmental conditions, geographic region, plant species, and harvest practices. [1]

Factors that can affect vitamin and mineral levels in forage include: [2][3]

Some nutrients decline further after forage is harvested. Once grass is cut and no longer actively growing, vitamin E and beta-carotene (the precursor to vitamin A) begin to degrade during drying and storage. [4]

As a result, hay contains much less of these nutrients than fresh pasture, with losses increasing the longer it is stored. This makes horses on hay-based diets more susceptible to deficiencies in these vitamins than horses with regular access to fresh pasture.

Even when a horse maintains weight and appears healthy, subclinical nutrient deficiencies can still affect normal physiological function in subtle ways. More obvious signs may only become apparent as deficiencies worsen or additional stressors increase nutritional demands. [5][6][1][7]

Based on this, most horses need a vitamin and mineral supplement to consistently meet their daily nutrient requirements. [7]

Supplementation helps fill common gaps in forage and provides nutrients needed to support healthy hooves and coat, metabolic and immune function, muscle function, exercise recovery, and overall health.

A well-formulated supplement should complement your horse’s forage by supplying essential vitamins, minerals, and other nutrients in amounts that help bring the total diet closer to the horse’s requirements.

Omneity Mineral Vitamin Supplement Review for Horses

Do Horses on Grain Need Vitamins & Minerals?

Commercial feeds can contribute vitamins and minerals to the diet, but their nutrient guarantees are dependent on feeding the full recommended amount based on the horse’s body weight and activity level.

For a typical adult horse, some complete feeds are formulated with feeding rates of 10 – 20 lb (4.5 – 9 kg) per day.

However, many easy keepers, maintenance horses, and horses with lower calorie needs are intentionally fed less than the recommended amount because they do not need the additional calories. Horse owners may also feed below the tag rate to reduce feed costs.

When a fortified feed is underfed, the horse also receives proportionally less of the added vitamins and minerals. A horse receiving half the recommended amount of feed will only receive about half of the intended fortification, which can leave major gaps in the diet. [6][8]

Even at the full feeding rate, grain-based feeds differ in the amounts and forms of nutrients they provide. Many use inorganic sources of trace minerals, which are not absorbed as efficiently as organic or chelated minerals, particularly when other minerals and dietary compounds interfere with absorption.

Grain feeds also do not necessarily provide every nutrient at optimal levels for the individual horse. Some formulas contain limited B-vitamin fortification or relatively low amounts of biotin, vitamin E, amino acids, and other nutrients, so horse owners must add separate hoof, coat, or performance supplements to provide these nutrients in adequate amounts.

For these horses, a comprehensive vitamin and mineral supplement can do more than compensate for an underfed grain ration. It can improve the overall quality of the diet by providing highly bioavailable minerals and optimal amounts of additional nutrients in one concentrated serving.

Mad Barn Omneity®: Comprehensive Vitamin & Mineral Support

Omneity® is Mad Barn’s all-in-one vitamin and mineral supplement for horses, designed to balance the majority of forage- and grain-based diets.

Omneity® was developed by Mad Barn founder and nutritionist Scott Cieslar, MSc, when he wanted higher-quality nutritional support for his own horses.

While there were many equine supplements available at the time, most products focused on a single nutritional concern, such as hoof quality, coat condition or muscle health.

Using several of these products together could result in excessive amounts of some nutrients while still leaving other requirements unmet. More comprehensive products were often too expensive, used low-quality ingredients, or contained additives Scott did not want, such as added iron.

To solve this, Scott formulated his own complete vitamin and mineral supplement to deliver a precisely balanced nutrient profile in one concentrated, low-NSC daily serving.

The formula was developed using hundreds of forage analyses and real-world equine diets to identify common nutrient deficiencies and imbalances.

Unlike basic ration-balancing supplements, Scott formulated Omneity with higher-quality organic trace minerals for better bioavailability, complete B-vitamin fortification, a full daily serving of vitamin E, 20 mg of biotin for hoof health, and yeast and digestive enzymes to support gut function, all without unnecessary added iron or excess sugar and starch.

As Scott began feeding the formula, other horse owners noticed the condition of the horses in his care and asked to start using his supplement. That product eventually became Omneity® and ultimately led to the founding of Mad Barn.

Omneity® is currently available in two forms: pellets and a powdered premix. Both provide the same nutrition, so the choice comes down to feeding preferences.

Omneity® Pellets provide vitamins and minerals in a palatable pelleted form, with low-NSC oat hulls used as a pelleting agent.

The pellets are a convenient option for picky eaters, boarding barns, and feeding programs where pellets are easier to measure and serve consistently.

What Makes Omneity® Different?

Horse owners have many options for supplementing vitamins and minerals, including ration balancers, multipurpose formulas, and single-ingredient products.

All of these products are intended to help meet nutrient requirements, but they differ in how completely they balance the diet, the quality and amounts of nutrients they provide, and the additional benefits they offer beyond basic fortification.

This is important because vitamins and minerals influence a wide range of physiological functions in the horse’s body. Adequate intake of these essential nutrients supports hoof growth, coat quality, muscle function, immune defenses, antioxidant protection, electrolyte balance, metabolism, and mood balance.

Omneity® was designed to go beyond basic vitamin and mineral coverage, providing comprehensive nutritional support for horses of all classes and activity levels. Its formula combines essential nutrients with amino acids, biotin, antioxidants, yeast, and digestive enzymes at levels selected to support the outcomes horse owners care about most.

The goal is to give horse owners one concentrated daily supplement that addresses the major nutritional needs commonly left unmet in equine diets. Whether your horse is on a forage-based diet or receives fortified grain, Omneity helps provide more complete and consistent nutritional coverage without requiring multiple overlapping supplements.

“Because it's formulated with high-quality essential nutrients, Omneity® helps support all aspects of your horse's health — hooves, immune system, and everything in between.”

Dr. Fran Rowe, DVM
Veterinarian & Nutritionist

Omneity® vs. Basic Vitamin Mineral Supplements

Basic vitamin and mineral supplements can help fill nutrient gaps, but many rely on inorganic mineral sources such as zinc sulfate, copper sulfate, manganese oxide, and sodium selenite.

These ingredients are less bioavailable and affected by interactions with other minerals in the digestive tract. In horses consuming high-iron hay, this can further reduce the absorption of nutrients such as zinc and copper.

Furthermore, basic products often do not provide optimal levels of all essential nutrients. Some leave out key nutrients, provide only small amounts of vitamins such as biotin, or do not include essential amino acids.

Live yeast and digestive enzymes may also be absent or included at token levels that are too low to have a meaningful physiological effect.

Omneity® vs. Ration Balancers

Traditional ration balancers can support broader nutritional requirements, but they are less concentrated and require larger serving sizes to meet daily needs.

This is because ration balancers are typically made with calorie- and protein-containing ingredients such as soybean meal, alfalfa meal, wheat middlings, and other feedstuffs. These products usually contain 28 – 32% crude protein and are fed at approximately 1 – 2.5 lb (0.45 – 1.1 kg) per day.

However, most horses already receive enough energy and protein from their forages. For these horses, feeding a ration balancer can add unnecessary protein and calories while requiring a larger daily serving and higher cost to provide vitamin and mineral fortification.

In comparison, an average 1,100 lb (500 kg) horse can have its daily vitamin and mineral needs covered with just 120 g (4.2 oz), or approximately one-quarter of a pound, of Omneity® Premix. A typical ration-balancer serving can weigh four to nine times as much.

omneity premix feeding-rate comparison

More importantly, Omneity® can provide more complete nutrition while simplifying the feeding program. Horses receiving Omneity® typically do not need separate hoof, antioxidant, coat, amino acid, or trace mineral supplements to cover these same nutritional needs.

Some premium ration balancers do include biotin, amino acids, or digestive-support ingredients, but they may not provide all of these nutrients at meaningful levels in a single formula. Adding separate supplements can increase both cost and complexity.

Omneity® is different because it combines these nutrients and functional ingredients at effective inclusion levels in one concentrated daily formula:

  • 100% organic trace minerals: Most ration balancers rely primarily on inorganic trace minerals, while some use a combination of organic and inorganic sources. Omneity® provides zinc, copper, manganese, and selenium entirely from organic sources, including 498 mg of zinc, 120 mg of copper, 240 mg of manganese, and 2.4 mg of selenium per full serving. Zinc, copper, and manganese are supplied as proteinates, while selenium is provided as organic selenium yeast. Omneity® is also formulated without added iron.
  • 20 mg of biotin: Some ration balancers either do not include biotin or provide only small amounts, often around 1 – 5 mg at the recommended feeding rate. Omneity® provides 20 mg per serving, matching the physiologically effective dose used in equine hoof studies.
  • Complete B-vitamin fortification: Many ration balancers provide only selected B-vitamins, and some do not include a complete B-vitamin complex at all. Omneity® guarantees daily amounts of thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, vitamin B12, biotin, folic acid, and choline.
  • Vitamin and antioxidant coverage: A full serving supplies 1,020 IU of vitamin E, 360 mg of vitamin C, and 2.4 mg of organic selenium to support antioxidant defenses, immune function, muscle health, and exercise recovery. Many ration balancers provide only partial antioxidant coverage, lower inclusion levels, or omit nutrients such as vitamin C entirely.
  • Essential amino acids: Each serving of Omneity® provides 3.4 g of lysine, 1.1 g of methionine, and 1.4 g of threonine to complement the protein supplied by forage. Some ration balancers guarantee crude protein without supplementing individual amino acids, so horses may still fall short in limiting amino acids even when total protein intake is adequate.
  • Two forms of digestive support: Omneity® combines Yea-Sacc® live yeast culture with Allzyme® SSF digestive enzymes to support hindgut microbial activity, feed breakdown, and nutrient utilization. Many ration balancers do not include live yeast or digestive enzymes, and some add them only at low inclusion levels.
  • Low-NSC formula: Omneity® is low in starch and sugar, with no unnecessary added sugars or starches and minimal calories per serving. It is suitable for horses that do not need additional feed volume, as well as those on controlled-starch or lower-calorie diets.

At just $0.84 per day with a subscription, Omneity® Premix is also a more affordable way to meet a horse’s nutritional requirements. A (55 lb) 25 kg bag provides 208 servings and will last almost seven months for a 1,100 lb (500 kg) horse.

Many ration balancers cost around $1.00 – $1.60 per day at recommended feeding rates, with some premium formulas costing considerably more. Cheaper ration balancers can bring the daily feed cost down, but the tradeoff is usually a less complete nutrient profile.

They may provide lower amounts of vitamin E or biotin, rely on lower-cost inorganic mineral sources, include less complete B-vitamin fortification, provide lower levels of supplemented amino acids, or skip meaningful amounts of live yeast and digestive enzymes.

That means the lowest-cost ration balancer is not always the lowest-cost feeding program. If separate hoof, antioxidant, amino acid, or digestive supplements are needed to provide the nutrients missing from the ration balancer, the combined daily cost can easily exceed the cost of Omneity® alone.

“Omneity is a product we often rely on as a simple, all-in-one way to balance the diet with high-quality nutrients, especially when forage-based feeding programs need a solid nutritional foundation.”

Benefits of Feeding Omneity®

After starting Omneity®, horse owners often notice a shinier coat, richer coat color, stronger new hoof growth, and a fuller topline.

Reviews also describe results including more visible dapples, harder feet, less cracking, better shoe retention, and increased mane and tail growth.

Some results, particularly coat shine, will become visible within the first few weeks of feeding Omneity®. Other results, such as hoof quality and topline, take longer because they depend on the growth of new tissue. [6][9]

  • Skin & Coat Health: Coat shine is often one of the first changes owners notice, with some reporting a visible difference within two to five weeks. Over time, owners may also see deeper color, less fading when turned out in the sun, and more visible dapples. In a 16-week Omneity® field study, the average coat-color score among supplemented horses increased from 2.75 to 4.63. However, the control horses darkened by a similar amount as seasonal UV exposure declined, so the difference between groups was not statistically significant.
  • Improved hoof growth: In the same controlled field study, Friesian geldings fed Omneity® with additional zinc and copper to balance unusually high-iron forage grew hoof wall 22% faster than unsupplemented controls. Average growth over 71 days was 3.77 cm in the supplemented group compared with 3.10 cm in the control group.
  • Stronger new hoof horn: Investigators also observed more uniform new hoof growth and fewer cracks in the supplemented horses. Omneity® customers report related changes such as harder feet, less chipping, reduced cracking, and better shoe retention. Existing weak or damaged horn cannot be repaired, so the improvement appears in the new hoof wall growing down from the coronary band.
  • Fuller topline and better muscling: Omneity® supplies limiting amino acids, vitamins, and minerals involved in muscle protein synthesis, contraction, tissue repair, and antioxidant protection. In a Mad Barn case study, a five-year-old Appendix gelding showed visible improvements in topline and overall muscling within two months after Omneity® was added to a revised feeding program.
  • Healthier mane and tail growth: Horse owners also report longer, thicker manes and tails, stronger hair growth, and less fading or breakage at the ends. These changes develop gradually as new hair replaces older growth and are generally more apparent after several months of consistent feeding.

Omneity® should be fed as part of a complete, balanced diet. It is formulated to supply vitamins, minerals, amino acids, and other nutrients that complement the rest of the feeding program, but it does not replace good-quality forage, adequate calorie and protein intake, or access to clean water and salt.

The horse’s overall diet and management will influence how well these nutrients can support normal tissue growth and body condition. Appropriate exercise is also necessary for muscle development and topline, while consistent daily feeding is important for maintaining a steady supply of nutrients over time.

Organic Trace Minerals

Trace minerals are nutrients that horses require in small amounts, but they play critically important roles in the body. Trace minerals support hundreds of enzyme systems involved in growth, metabolism, immune function, connective tissue, hoof quality, skin health, and antioxidant defenses. [10]

Omneity® provides all of the essential trace minerals that are not supplied in adequate amounts by forage alone. [6]

  • Zinc: Supports hoof and skin health, protein synthesis, immune function, and antioxidant enzyme activity
  • Copper: Supports connective tissue formation, iron metabolism, coat pigmentation, and antioxidant defenses
  • Manganese: Supports cartilage and bone formation, carbohydrate and fat metabolism, and antioxidant enzyme activity
  • Selenium: Works with vitamin E to support antioxidant protection, muscle function, and normal immune responses
  • Iodine: Required for thyroid hormone production and normal regulation of metabolism
  • Cobalt: Required by hindgut microbes for synthesis of vitamin B12, which supports energy metabolism and red blood cell production

Omneity® is formulated with 100% organic trace minerals, meaning the minerals are bound to organic molecules such as amino acids or proteins. This form can help support mineral bioavailability and reduce competition for absorption in the digestive tract, helping the horse make effective use of the trace minerals provided in the diet. [11][12][13]

Vitamins & Antioxidants

Vitamins support normal physiological function throughout the body, including immune defenses, muscle function, vision, skin health, tissue maintenance, and antioxidant protection.

While forage supplies many vitamins, concentrations can decline during storage, and intake varies depending on pasture access and forage quality. [14]

For example, fresh pasture is an important source of vitamin E, so horses with limited grazing or those fed stored hay for extended periods may consume less vitamin E from the diet. [15]

Omneity® provides vitamins A, D3, E, and C to help maintain adequate vitamin intake and support the following functions:

  • Vitamin A: Supports vision, immune function, reproduction, and healthy skin and epithelial tissues
  • Vitamin D3: Supports calcium and phosphorus metabolism, bone health, and normal muscle function
  • Vitamin E: Provides antioxidant protection and supports muscle, nerve, and immune function
  • Vitamin C: Supports antioxidant defenses, collagen synthesis, and normal tissue maintenance

B-Vitamins

The B-complex vitamins are usually grouped together because they have related roles in energy metabolism and many other cellular processes throughout the body. B-vitamins support nervous system function, red blood cell formation, amino acid metabolism, and skin and hoof health.

Microbes in the horse’s hindgut can produce several B-vitamins through fermentation, so specific dietary requirements have not been established for many of these nutrients. But this does not mean that B-vitamins are unimportant or that horses have no physiological requirement for them.

Instead, microbial production is generally assumed to contribute enough B-vitamins under normal conditions that specific amounts do not need to be supplied in the diet.

However, during periods of stress, illness, intense exercise, growth, or increased metabolic demand, endogenous production may not always provide the amount needed to support optimal function. Dietary intake and digestive health can therefore influence overall B-vitamin status. [1][16][17]

Omneity® provides a full spectrum of B-vitamins to support the following functions:

  • Vitamin B1 (Thiamine): Supports carbohydrate metabolism and normal nervous system function
  • Vitamin B2 (Riboflavin): Supports cellular energy metabolism and antioxidant enzyme activity
  • Vitamin B3 (Niacin): Supports energy metabolism and normal cellular function
  • Vitamin B5 (Pantothenic Acid): Supports energy production and the metabolism of fats, carbohydrates, and proteins
  • Vitamin B6 (Pyridoxine): Supports amino acid metabolism, neurotransmitter production, and red blood cell formation
  • Vitamin B7 (Biotin): Supports keratin production, hoof growth, skin health, and coat quality
  • Vitamin B9 (Folic Acid): Supports DNA synthesis, cell division, and red blood cell formation
  • Vitamin B12 (Cobalamin): Supports energy metabolism, amino acid metabolism, and red blood cell formation

Biotin is particularly important for hoof quality because of its role in keratin production. Omneity® provides a full daily serving of biotin to support healthy hoof growth, skin, and coat quality when fed consistently as part of a balanced diet. [18]

Amino Acids

Amino acids are the building blocks of protein. When horses digest protein from forage and feed, it is broken down into amino acids that the body uses to build and repair muscle, connective tissue, hooves, skin, enzymes, hormones, and other proteins.

Some amino acids can be produced by the horse, while essential amino acids must be supplied by the diet. The amount of crude protein in a feed does not tell you whether it provides enough of each essential amino acid.

This is important because protein synthesis depends on having the necessary amino acids available in the right amounts. If one essential amino acid is supplied in too small an amount, it can limit the horse’s ability to use the other amino acids to make body proteins. [6][19]

As a result, a horse can consume adequate total protein but still have an inadequate supply of specific amino acids needed for muscle maintenance, tissue repair, and other protein-dependent functions.

Omneity® supplies lysine, methionine, and threonine, which are among the amino acids most likely to limit protein quality in equine diets. It also provides additional high-quality protein from whey.

Together, these nutrients help provide a more complete amino acid profile to support protein synthesis, topline and muscle maintenance, tissue repair, hoof growth, and recovery after exercise.

Macro Minerals

Although trace minerals receive a lot of attention, horses also require much larger amounts of macrominerals. These minerals are needed for structural, metabolic, muscular, and fluid-regulating functions throughout the body. [6][20]

Omneity® provides calcium, phosphorus, magnesium, sodium, and chloride to complement the amounts supplied by forage and other feeds. [21]

  • Calcium: Supports bone and tooth structure, muscle contraction, nerve transmission, and normal cellular signaling
  • Phosphorus: Supports bone structure, cellular energy metabolism, and the formation of important compounds such as ATP and phospholipids
  • Magnesium: Supports muscle and nerve function, enzyme activity, energy metabolism, and bone health
  • Sodium: Supports fluid balance, nerve impulses, muscle contraction, and normal hydration
  • Chloride: Works with sodium to maintain fluid and acid-base balance and is also required for normal digestive function

Because macrominerals are required in relatively large amounts, their total intake and balance should be evaluated across the entire diet, including hay, pasture, concentrates, and supplements. A forage analysis or complete diet evaluation can help determine whether an individual horse’s requirements are being met.

Digestive Enzymes

Even a well-balanced diet can only support the horse if its nutrients are properly digested and absorbed. Digestive enzymes help break larger nutrients in feed into smaller components that can be used more efficiently by the horse or further fermented by microbes in the digestive tract.

Omneity® includes enzymes from an Aspergillus niger fermentation product that help support the digestion of several major components of the diet. [5]

  • Carbohydrate-digesting enzymes: Help break down complex carbohydrates such as starch and glucan into smaller sugars that can be more readily digested
  • Fiber-degrading enzymes: Help break down structural components of fiber, making more of the feed available for microbial fermentation in the hindgut
  • Protein-digesting enzymes: Help break proteins into smaller peptides and amino acids that can be absorbed and used by the horse

By supporting the breakdown of feed before nutrients are absorbed or fermented, these enzymes help improve nutrient availability and utilization from the overall diet.

Live Yeast Cultures

Much of the horse’s digestion happens with the help of microbes in the hindgut. These bacteria, protozoa, fungi, and other microorganisms ferment fiber that the horse cannot digest with its own enzymes, producing volatile fatty acids that provide an important source of energy to the horse.

Omneity® includes Saccharomyces cerevisiae 1026 (Yea-Sacc® Extra), a live yeast culture used to support the environment in which these beneficial hindgut microbes function. [22][23]

  • Supports fiber fermentation: Helps maintain microbial activity involved in breaking down forage and other fibrous feeds
  • Supports hindgut conditions: Helps maintain an environment that favors normal populations of fiber-fermenting microbes
  • Supports feed utilization: More efficient fermentation can help the horse obtain more usable nutrients and energy from forage

Supporting healthy hindgut fermentation is particularly important because forage should make up the majority of the equine diet. Live yeast complements good forage and feeding management by helping maintain normal microbial fermentation and digestive efficiency.

“I want the best for my horses, and that's why I feed them Omneity. That way I'm sure their vitamin and mineral needs are met with high-quality and safe ingredients. It also provides much-needed hoof and digestive health support, all in one easy-to-feed supplement.”

Omneity® Premix vs. Omneity® Pellets

Omneity® Premix and Omneity® Pellets are designed to provide the same comprehensive balance of vitamins, minerals, amino acids, and digestive support ingredients. The main difference is the delivery format.

Omneity® Premix is a loose, concentrated powder that can be mixed into the horse’s existing feed. It should be fed with a carrier, such as beet pulp, soaked hay cubes, or concentrates, to help ensure the full serving is consumed.

Because the Premix does not contain the additional ingredients needed to form a pellet, it has a smaller daily serving size of 120 grams and a lower cost per day.

Omneity® Pellets provide the same nutritional support in a convenient, palatable pelleted format. Some horses prefer the texture and consistency of pellets, while others readily consume the Premix.

The pellets are made with low-NSC ingredients, making them suitable for all classes of horses, including easy keepers and horses that require controlled sugar and starch intake.

Both formats provide the same core nutritional benefits, so owners can choose the option that best fits their horse’s preferences, feeding program, and budget.

Format Best for Primary advantage Ideal use
Omneity® Premix Horses that readily eat powder mixed into a carrier Smaller serving size and lower daily cost You want the most economical option and already feed beet pulp, hay cubes, concentrates, or another carrier.
Omneity® Pellets Horses that prefer pellets or are reluctant to eat powdered supplements Palatable pelleted format that is easy to portion and feed Your horse prefers pellets or you want a format that does not need to be mixed into a carrier.

Which Horses Should Use Omneity®?

Omneity® is designed for horses that need vitamin and mineral supplementation to balance their diet. It can be fed to horses of all ages and classes, including adult horses, growing horses, foals and weanlings, broodmares, breeding stallions, performance horses, easy keepers, minis, and donkeys.

The amount fed should reflect the horse’s body weight, life stage, workload, and the nutrients already supplied by the rest of the diet. Horses with higher nutrient requirements, such as growing horses, broodmares, or horses in heavy work, may require more. Horses already receiving vitamins and minerals from a fortified grain or complete feed may require less Omneity® to avoid unnecessary overlap.

Mad Barn’s nutritionists can review your horse’s forage, feed, supplements, and individual requirements for free and recommend an appropriate serving of Omneity® as part of a balanced feeding program.

Omneity® is particularly useful when hay or pasture makes up most of the diet, since forage alone will not provide all vitamins and minerals in the amounts and proportions horses require.

Omneity® is a good fit when:

  • Hay or pasture provides most or all of the horse’s calories
  • The horse is fed little or no fortified grain or complete feed
  • The horse receives less than the manufacturer-recommended serving of a fortified feed, so the full vitamin and mineral contribution is not being supplied
  • The diet needs additional vitamins, trace minerals, amino acids, and digestive support without adding a large amount of calories
  • The horse’s calorie needs are already being met, but the diet still needs to be balanced for micronutrients
  • You want one comprehensive supplement instead of feeding several separate vitamin, mineral, amino acid, and digestive support products
  • The horse needs more support for healthy hoof growth or to help maintain normal coat pigmentation and reduce sun bleaching

Because the serving can be adjusted based on the rest of the ration, Omneity® is flexible enough to fit a wide range of feeding programs. Even horses receiving fortified grain can be fed Omneity® at an appropriate amount to fill remaining nutrient gaps without unnecessarily duplicating nutrients already supplied by the feed.

When Another Formula May Be a Better Fit

Omneity® is a good fit for most horses that need standard vitamin and mineral support, but some horses benefit from a formula with higher levels of specific nutrients.

Mad Barn’s AminoTrace+ is a vitamin and mineral pellet that provides enhanced support for horses with higher trace mineral or amino acid needs. It may be a better choice for:

  • Horses consuming high-iron forage or water, where higher levels of copper and zinc may be needed to improve overall mineral balance
  • Horses with metabolic concerns that benefit from a low-NSC formula with higher nutrient concentrations and additional antioxidant support
  • Performance horses with greater demands for lysine, methionine, threonine, and other nutrients involved in muscle maintenance and recovery
  • Horses with a history of poor hoof quality, coat bleaching, or other signs that the diet may need higher levels of copper, zinc, or amino acids
  • Horses whose forage analysis shows mineral imbalances that are not fully addressed by a standard serving of Omneity®

It is also possible to feed Omneity® and add individual nutrients, such as copper, zinc, or amino acids, when a horse needs more targeted support. However, when several of these nutrients need to be increased at the same time, AminoTrace+ can provide a more practical and complete option.

For metabolic horses, horses on high-iron forage, and horses with higher performance or amino acid demands, upgrading to AminoTrace+ may make more sense than adding several separate supplements to Omneity®.

A complete diet evaluation can help determine whether Omneity®, AminoTrace+, or a more customized feeding plan is the best fit for the horse.

Why Choose Omneity® for Your Horse

Omneity® is designed to make it easier to provide horses with the nutrients that are commonly missing or insufficient in forage- and grain-based diets.

A single daily serving provides a comprehensive combination of vitamins, minerals, amino acids, antioxidants, biotin, digestive enzymes, and live yeast. This supports much more than basic vitamin and mineral requirements, with nutrients that contribute to healthy hooves and coat, muscle and topline maintenance, antioxidant defenses, normal metabolism, and digestive function.

Key benefits of Omneity® include:

  • All-in-one balancer: Helps fill common vitamin and mineral gaps in forage-based diets and underfortified grain rations
  • Healthy hooves and coat: Provides 20 mg of biotin along with organic zinc, copper, amino acids, and other nutrients involved in hoof and hair growth
  • Muscle and topline support: Supplies lysine, methionine, threonine, vitamin E, and minerals involved in protein synthesis, muscle function, and tissue repair
  • High-quality mineral sources: Uses 100% organic trace minerals to support absorption and utilization of zinc, copper, manganese, and selenium
  • Comprehensive vitamin coverage: Provides vitamins A, D3, E, and C along with a full spectrum of B-vitamins
  • Digestive support: Combines digestive enzymes with live yeast culture to support feed breakdown, hindgut fermentation, and nutrient utilization
  • Low-NSC nutrition: Provides concentrated nutrients without adding significant sugar, starch, calories, or feed volume
  • Fewer separate supplements: Combines nutrients commonly supplied through separate hoof, coat, amino acid, antioxidant, and digestive products

Omneity® can be used across a wide range of feeding programs, with the serving adjusted according to the horse’s size, workload, life stage, and the nutrients already supplied by the diet.

For horse owners, the main advantage is confidence: instead of trying to address individual nutrient gaps with multiple products, Omneity® provides a professionally balanced and comprehensive daily supplement designed to help horses meet their nutritional requirements.
