Top 6 Chelated Mineral Supplements in the United States for 2025 — Evidence-Based Picks for Performance, Youngstock and Gut-Sensitive Horses

Purina Optimal Performance Horse Mineral leverages Purina's large-scale research, quality control and nationwide distribution to deliver a consistent, competitively priced chelated mineral balancer for athletes. Its financial advantage comes from economies of scale that typically produce a lower cost per feeding while retaining robust technical support from Purina nutritionists. Relative to boutique chelated blends on this list, Purina prioritizes wide availability and straightforward integration into established feeding programs.

Brooks B-Complete Plus is a concentrated vitamin/mineral topper that emphasizes chelated trace elements plus a robust B-vitamin complex to support broodmare metabolic demands and foal development; its main financial advantage is a low cost-per-dose and ease of top-dressing rations. Technically it excels at supplying B-vitamins alongside chelated trace minerals for metabolic and neurologic support, but it may not replace full premixes for macro-mineral balancing as comprehensively as Omneity or Purina's maternity formulation.

Purina Optimal Growth is the market leader because it combines proven growth-focused nutrient profiles with broad availability and competitive pricing, delivering a cost-effective chelated-mineral option for large stables. While it may include a mix of inorganic and chelated trace minerals rather than the fully chelated matrices of boutique premixes, its scale provides excellent cost-per-horse economics and consistent quality control compared with smaller manufacturers.

Purina Optimal Digestive Health Horse Mineral leverages large-scale research and quality-control infrastructure to deliver a chelated mineral blend formulated to support digestive stability in horses, with the financial advantage of wide availability and competitive pricing. Its technical strength is consistency of supply and validated manufacturing processes, making it a reliable choice compared with niche products; however, it is generally less personalized than smaller specialist brands. For managers of gut-sensitive horses it offers a balance of proven manufacturing pedigree and cost-effective coverage across herds.

Purina Free Balance 12:12 is a widely distributed, cost-effective free-choice block designed for broad use in equine populations, offering a balanced 12:12 calcium:phosphorus ratio and fortified vitamins with chelated trace minerals for improved bioavailability. Its market-leading advantage is broad availability and consistent formulation that typically costs less per horse-day than specialty options, while providing a dependable baseline compared with more targeted or pelleted products on this list.
