Most horses in North America are living on forage — hay, pasture, or both — and that is exactly as it should be. But forage alone does not cover the full picture. Depending on what your hay actually contains, there are predictable gaps in vitamins, trace minerals, and essential amino acids that no amount of feeding more hay will fix. A complete vitamin and mineral premix is the most efficient way to address those gaps in a single product. Omneity Premix from Mad Barn is the one I come back to most often when people ask where to start.

This post covers what Omneity Premix actually contains, how it compares to Omneity Pellets (the same formula in a different form), when a different product makes more sense, and what honest limitations to keep in mind before you order. If you want the deeper science behind any of this, Mad Barn publishes a genuinely thorough nutrition library — I will point you there rather than paraphrase it imperfectly.
What a “Complete” Premix Actually Means
The word complete gets used loosely in the supplement industry, so it is worth being specific about what Omneity Premix actually covers.
Omneity Premix is formulated to supply vitamins A, D, E, and K, the full B-vitamin complex, all major trace minerals (zinc, copper, manganese, iron, iodine, cobalt, selenium), and macrominerals, using organic chelated forms of the trace minerals where bioavailability matters most. It also includes essential amino acids — lysine, methionine, and threonine — which are the three most commonly limiting in typical hay-based diets. On top of that, the formula incorporates digestive enzymes, yeast, and biotin.
That is a meaningful difference from a product that covers only vitamins and ignores amino acids, or one that supplies minerals in cheap inorganic forms with lower absorption. The chelation piece is not marketing language — organic trace minerals generally show meaningfully better uptake than sulfate or oxide forms, particularly for zinc and copper, which show up as deficient more often than almost anything else in hay analysis.
What Omneity Premix does not do: it does not replace the calorie content of grain, it does not supply omega-3 fatty acids, and it does not address a horse whose needs are elevated by metabolic conditions. It is designed for the average horse on decent forage who needs the nutritional gaps filled without unnecessary extras. For most horses in most situations, that is exactly what is needed.
One thing to say plainly here: whether a product “balances” your horse’s diet depends entirely on what is in your forage. You cannot know what you are filling in until you know what is already there. A hay analysis is the right starting point. Your vet or an equine nutritionist can interpret it. Omneity Premix is formulated to address gaps that are common across typical hay samples — but common is not the same as universal, and your hay may not be typical.
Omneity Premix vs. Omneity Pellets: Which Form Should You Buy?
Mad Barn makes the same formula available in two forms: the loose powder (Omneity Premix, from $54.99) and the pelleted version (Omneity Pellets, from $45.99). The formula is identical. The choice comes down to your horse and your feeding setup.
| Omneity Premix | Omneity Pellets | |
|---|---|---|
| Starting price | from $54.99 | from $45.99 |
| Form | Loose powder | Pelleted on oat-hull base |
| NSC content | Effectively none | Low — oat-hull base |
| Best for | Horses that accept powder mixed into feed | Picky eaters, horses with little to no carrier feed |
| Carrier feed needed? | Yes — needs something to stick to | No — self-contained |
| Cost per serving | Slightly higher than pellets per lb | Slightly lower price point |
The Premix is the more economical option if your horse is getting any kind of carrier feed — even a small handful of hay pellets or beet pulp as a supplement vehicle will work. The powder mixes into feed cleanly and at the feeding rates on the label, the volume is small enough that most horses eat it without issue.
The Pellets earn their place with genuinely picky horses who sort or spit out powder, and with horses fed in a dry lot or on hay only with no carrier feed to mix into. The pelleted form is self-contained — it goes in the bucket as-is. The oat-hull base is low-NSC, which matters for easy keepers and metabolic horses, though for horses with significant insulin sensitivity concerns there is a better product (more on that below).
Both forms carry no added sugar and no fillers. That is worth noting because a lot of commercial vitamin and mineral pellets are formulated on a molasses or grain base that adds unnecessary calories and sugar for horses who do not need them.
If your horse is between the two — accepts powder sometimes, refuses it other times — I would go with Pellets for consistency. The small price difference does not matter if the Premix ends up in the corner of the feed tub.

When Omneity Is Not the Right Starting Point
Omneity Premix is a strong default, but it is not the right tool for every horse. Two situations where I would steer you elsewhere:
The metabolic or insulin-resistant horse. If your horse is an easy keeper, cresty-necked, laminitis-prone, or has been diagnosed with EMS, PPID, or insulin resistance, that is a veterinary conversation first and a supplement conversation second. Omneity is not wrong for these horses, but AminoTrace+ is formulated specifically with elevated zinc, copper, chromium, magnesium, and natural vitamin E that many practitioners prefer for this population. Do not stack AminoTrace+ with Omneity — they serve the same function and overlapping them creates excess mineral intake. Choose one based on your horse’s situation and your vet or nutritionist’s guidance.
The horse on pasture with limited hay. Fresh pasture supplies meaningful levels of natural vitamin E in a way that hay does not — hay loses most of its vitamin E within a few weeks of cutting. A horse on good summer pasture has different baseline vitamin E status than a horse eating dry hay through winter. This does not mean Omneity is wrong, but it is context that matters when you are evaluating whether the supplemental E in the premix is sufficient for your horse’s situation, particularly for horses with high oxidative stress from heavy work. For those horses, standalone Natural Vitamin E may be worth adding to any base program. Run that decision by your vet or a nutritionist — vitamin E status can be confirmed by bloodwork.
The horse with a known protein deficiency. If your vet or nutritionist has identified that your horse’s forage is genuinely low in protein quality — think topline loss confirmed by assessment, not just eyeballing — the amino acid content in Omneity may be enough, or you may need the addition of Three Amigos to address lysine, methionine, and threonine specifically. Three Amigos is designed to layer on top of a balancer program, not replace it.
I talk through how to think about layering supplements and reading nutrition labels in more depth on the podcast if you want the longer version of any of this.
Practical Notes Before You Order
A few things worth knowing before the box arrives:
Serving size is on the label — follow it. I am not going to give you a scoop number here because the right amount depends on your horse’s weight, work level, and what else is in the diet. Mad Barn’s label guidance is clear, and their team is genuinely responsive if you have questions about your specific horse.
Storage matters with powder. Omneity Premix is a loose powder. Keep it sealed and away from moisture — a damp barn environment can cause it to clump and degrade. Many people transfer it to a sealed plastic container for daily barn use.
Give it time. Vitamin and mineral programs are not two-week interventions. The changes you are supporting — hoof growth, coat quality, overall resilience — happen on biological timelines measured in months, not weeks. Many owners feeding Omneity report meaningful changes in coat quality and hoof growth rate after sixty to ninety days. That is consistent with how nutrients work in living tissue.
This is a supplement, not a diet. Forage should still be the foundation. No premix corrects a horse on insufficient calories, inadequate protein in the base diet, or poor overall management. The supplement fills gaps in a good diet — it does not substitute for one.
Mad Barn publishes detailed, well-sourced nutrition articles on their site that cover the research behind chelated minerals, amino acid requirements in horses, and vitamin E bioavailability in more depth than I can reasonably cover here. I would point you there before making any major diet change — link through my referral and the content is all free.
If you are feeding your horse primarily on forage and looking for one product that covers the foundational bases without unnecessary fillers, added sugar, or ambiguous sourcing, Omneity Premix is the place to start. The pellet version is there if your horse insists on it. And if your horse has metabolic concerns or elevated needs, the conversation starts with your vet — not a shopping cart.
