Best Equine Vitamin Mineral Supplement: A Feed Room Look at Omneity® and AminoTrace+

For many horses, the best place to start is not another scoop of grain. It is a balanced daily vitamin and mineral foundation that fits the forage, the horse, and the way the barn actually feeds.

A Practical Question for Horse Owners

Ask around any feed store long enough and the same question comes up in different words: what is the best equine vitamin mineral supplement for my horse?

The answer depends less on the label and more on what is missing from the diet. Hay and pasture should do the heavy lifting in a horse’s ration, but forage does not always supply enough vitamin E, selenium, copper, zinc, sodium, or key amino acids. Fortified feeds can help, but only when fed at the full recommended rate. Many horses get less than that because they simply do not need the extra calories.

That is where a concentrated vitamin and mineral supplement earns its place. It lets owners balance the diet without adding unnecessary sugar, starch, fillers, or iron.

What a Good Supplement Should Do

A well-formulated balancer should cover common forage gaps and support the things owners see every day: hoof quality, coat condition, topline, immune function, normal metabolism, and recovery from work.

Look for organic trace minerals, adequate vitamins A and E, complete B-vitamin support, biotin, and the limiting amino acids lysine, methionine, and threonine. Also look for no added iron. Most horses already get plenty of iron from forage, and too much can make copper and zinc harder to use.

Plain loose salt still deserves its own spot in the feed room. Sodium requirements are too large to be fully covered by a concentrated supplement, so most horses need daily salt plus free-choice access.

Best Overall: Omneity®

For most horses, Omneity® is the first recommendation. It is designed as an all-in-one vitamin and mineral supplement for forage-based diets and underfortified grain programs.

Omneity® provides 100% organic trace minerals, B-vitamins, vitamin E, biotin, essential amino acids, yeast, and digestive enzymes. It is low in sugar and starch and contains no added iron. In barn terms, it is the broad foundation product: useful for horses on hay, pasture, light grain, or a ration that needs cleaning up and simplifying.

The line gives owners two practical formats. Omneity® Premix is the powdered option, fed at 120 grams per day for a 500 kg (1,100 lb) horse. It is the most concentrated and economical choice when the horse already eats a mash, soaked feed, beet pulp, or another carrier.

Omneity® Pellets provide the same core nutritional support in an easy-feeding pellet, fed at 200 grams per day for a 500 kg horse. They are often the better fit for picky horses, horses not getting a carrier feed, or barns that prefer a simple pelleted scoop.

When to Step Up: AminoTrace+

Some horses need more than a standard daily balancer. AminoTrace+ is the enhanced option for horses with higher nutrient demands, metabolic concerns, hoof problems, high-iron forage, or a history of laminitis.

Compared with Omneity®, AminoTrace+ supplies higher levels of copper, zinc, magnesium, natural vitamin E, and limiting amino acids. It also provides 20 mg of biotin per serving, yeast and prebiotic support, no added iron, and a low-NSC formula for easy keepers or horses needing lower sugar and starch intake.

That makes AminoTrace+ a strong choice for horses with EMS, PPID, insulin dysregulation, persistent poor hoof quality, or greater demands from training, travel, and recovery.
