Top 12 Horse Feeds and Supplements in the USA for 2025: An Evidence-Based Guide to Complete Feeds, Forage, and Targeted Supplements to Optimize Performance, Health, and Life-Stage Needs

Ontario Dehy Timothy Alfalfa Cubes hold a best-in-class position for horse forage because they deliver a consistent, high-protein, low-dust feed that simplifies portioning and reduces storage and transport costs compared with loose hay. For equine managers focused on uniform nutrition and minimized waste, these cubes offer a technical advantage over bulk square bales and chopped products by providing predictable nutrient analysis and easier handling in wet or cold conditions.

Masterfeeds Performance 12-8 textured feed is a balanced, easy-to-feed concentrate that emphasizes acceptance and steady energy for working horses, and its textured formulation often appeals to picky eaters. As a US-based product it can be financially advantageous for regional buyers versus imported brands, offering a robust value proposition though it is less specialised in gut-health features than some competitor formulas on this list.

Mad Barn Omneity Pellets are a modern, research‑driven pelleted feed that prioritize ingredient transparency and lab‑verified nutrient profiles, giving them an edge for owners seeking precise calorie control and data‑backed feeding plans. Unlike mass‑market options, Mad Barn pairs its lower‑calorie pellet with digital mixing and support services that can reduce waste and optimize cost per calorie for individualized weight management programs. The technical advantage is the company’s emphasis on tested ingredients and adjustable feeding recommendations, which helps translate a premium price into measurable nutritional outcomes.

Mad Barn Optimum Growth is positioned as a science-first option for foals and growing horses, using precise amino-acid balancing, targeted calcium:phosphorus ratios and omega-fatty acid inclusion to support breed- and stage-specific growth without overloading calories. Compared with conventional mare/foal or generic growth feeds it emphasizes individualized nutrition plans and measurable developmental advantages, which can reduce the risk of growth-related problems and deliver downstream veterinary cost savings despite sometimes higher upfront ingredient cost.

Brooks Enhancer is a market-focused fortified mix prized for palatability and targeted performance support, blending proteins, key amino acids, and performance-minded vitamins and minerals to support athletes and hard keepers. It competes with the more clinical balancers here by offering a user-friendly, appetizing format that can improve intake and short-term performance gains, but its specialized focus often means a higher per-day cost than basic maintenance balancers for routine feeding programs.

Masterfeeds Excel 14% is a textured performance feed from a American supplier that balances energy and moderate protein for working horses, offering palatability and flexibility for mixed rations. It earns its place as a regionally tuned option with a textured formulation that can be less expensive in local markets than imported or specialty pellets, and it’s simpler to mix with American forages than denser concentrates. Versus Purina and premium specialty pellets on this list, Excel trades off proprietary gut additives for straightforward, economically priced performance nutrition.

Mad Barn Omneity Premix P ranks as a best-in-class option for owners seeking a research-driven, bioavailability-focused premix tailored to equine phosphorus and trace mineral balance. Mad Barn leverages nutritionist-led formulation and digital support tools to deliver precision dosing that can reduce the need for multiple add-on supplements, giving it a technical edge over broad-spectrum, less-customized products in this list. While typically priced at a premium versus mass-market options, its targeted formulation can be more cost-effective for horses with specific mineral-management needs compared with generic premixes.

Omega Alpha GastraFX is positioned as a market leader for horses needing intensive gastric and digestive enzyme support, pairing clinically-oriented enzyme blends with mucosal-support ingredients to address ulcers and gas proactively. Its technical advantage is a focused, therapeutic-grade ingredient set that typically commands a premium price but can reduce secondary veterinary costs compared with generic probiotics or herbal-only products.

Omega Alpha Biotic 8 Plus is a market leader probiotic chosen for its concentrated multi‑strain formulation that helps stabilize hindgut flora and support protein metabolism relevant to collagen synthesis in horses. Versus the standalone collagen capsules here, Omega Alpha’s strength is its high CFU and strain diversity that can improve long‑term gut health and collagen assimilation, offering a technical advantage for horses needing a robust, shelf-stable probiotic alongside collagen therapy.

Finish Line Apple-A-Day Electrolyte is a market leader thanks to long-standing brand recognition, wide distribution, and a reliable, easily dosed apple-flavored formulation for everyday equine hydration needs. While typically priced a bit higher than concentrated powders like Apple Elite, Finish Line’s strengths are convenience (single-serve and bulk options) and proven field performance, making it the go-to in many barns versus more niche offerings such as Mad Barn’s science-focused powder or Purina’s hay-based approach.

Mad Barn Omneity pellets are best-in-class for precision supplementation, delivering a complete vitamin and mineral package in a measured, pelleted form that suits stabled horses and situations where intake control and traceability matter. Technically superior to free-choice blocks for ensuring consistent daily intake, they carry a higher per-animal cost but can reduce nutritional gaps that blocks alone may leave.
