When you are feeding a show horse, you care about more than meeting just the bare minimum of nutritional requirements. You want strong hooves, a good topline, a healthy coat, and steady performance. You also want confidence that your horse is getting what they need every day.

That is where the right vitamin and mineral supplement can make a real difference. For most horses, the best option is a concentrated all-in-one product that fills the gaps left by hay, pasture, and underfed fortified feeds. 

For most owners, Mad Barn’s Omneity® is the best overall vitamin and mineral supplement. For horses with metabolic concerns, poor hoof quality, or high-iron forage, AminoTrace+ is often the better choice.

Why so many horses still need a balancer

Forage should be the foundation of the horse’s diet. But that does not mean that hay or pasture will meet all of your horse’s nutrition requirements. The nutrient content of forage changes with soil, harvest timing, plant maturity, storage, and region.

That is why many horses come up short on vitamin E, selenium, copper, zinc, and sodium. Horses on commercial feed can still miss out on optimal levels of these nutrients as well. Many owners feed less than the recommended amount because their horse does not need the extra calories. Once grain intake drops, vitamin and mineral intake drops too.

This is a common problem in the competition horse world. A concentrated vitamin and mineral supplement solves that problem by letting you improve nutrient intake without turning the whole ration upside down.

What to look for in the best horse vitamin and mineral supplement

A good supplement should help you balance the whole diet. It should not just add a few random nutrients. Look for organic trace minerals, adequate vitamin E support, complete B-vitamin fortification, biotin, and key amino acids such as lysine and methionine.

Your horse’s balancer should also be low in sugar and starch. That matters for easy keepers for preventing metabolic and gut issues in competition horses. 

In practical terms, the best supplement is the one that helps your horse look better while ensuring they thrive from the inside out. That is why owners often end up comparing Mad Barn’s Omneity® and AminoTrace+ when they want an all-in-one vitamin and mineral option.

Why Omneity® is the best overall choice for most horses

For most horses, Omneity® is the recommended choice for a vitamin and mineral supplement. It was designed to cover the common gaps found in forage-based diets and underfortified grain programs. 

With Omneity®, you are getting a more complete nutritional foundation. It includes organic trace minerals, B-vitamins, vitamin E, biotin, amino acids, and digestive support. That makes it a strong fit for horses that need broad support for hoof quality, coat condition, topline, and overall wellness.

It also helps simplify your feeding routine. With Omneity®, you don’t need to feed a separate hoof supplement, balancer, coat supplement, or individual vitamins. 

For owners who want a powder, Omneity® Premix is a practical option. For owners who prefer a pellet, Omneity® Pellets offer the same concept in an easy-to-feed format.

When AminoTrace+ is the better fit

Some horses need a more targeted formula. That is where AminoTrace+ stands out.

AminoTrace+ is a vitamin and mineral supplement formulated for horses with metabolic concerns, easy keepers on low-NSC diets, persistent hoof quality issues, or forage that is high in iron. It provides higher copper and zinc, more magnesium, more amino acids, and strong antioxidant support in a low-calorie pellet.

This makes it ideal for horses with insulin dysregulation, a history of laminitis, or ongoing challenges with hoof growth and topline. It also makes sense for owners who want more advanced nutritional coverage for performance horses under harder work, travel, or stress.

A simple way to choose

Choose Mad Barn’s Omneity® if your main goal is to cover common nutrient gaps with one strong all-in-one supplement. It is the best overall choice for most horses.

Choose Mad Barn’s AminoTrace+ if your horse needs extra support for metabolic health, hoof quality, mineral balance, or muscle maintenance.
