Protected equine supplement features spotlight ration-balancing trend

Two equine publications, Equus and The Horse, have published sponsored, subscriber-protected articles focused on choosing vitamin and mineral supplements for horses, with Equus crediting Mad Barn and The Horse running a staff byline on a sponsored package. Because the articles are behind protection, the full recommendations aren’t publicly visible, but the topic aligns with a broader push in equine nutrition toward forage-first diet balancing, targeted trace mineral supplementation, and more scrutiny of whether a horse actually needs a concentrated supplement versus a ration balancer or fortified feed. AAEP’s 2025 client education materials emphasize that trace minerals such as zinc, copper, manganese, iodine, iron, and selenium play essential roles in hoof health, immunity, bone development, metabolism, and performance, while Merck notes that deficiencies and excesses can both create clinical problems.

Why it matters: For veterinarians and equine nutrition professionals, the practical issue isn’t just product selection, it’s preventing imbalance. Current guidance points back to forage analysis, total ration review, and matching supplementation to life stage, workload, geography, and existing fortified feeds. That matters because over-supplementation, especially with trace minerals such as selenium, can be harmful, and some common deficiencies, including vitamin E in horses on hay-based diets with limited pasture access, can be clinically significant. Sponsored educational content may also shape pet parent purchasing decisions, so clinicians may see more questions about “best” supplements and need to steer those conversations toward evidence-based diet evaluation rather than brand-first choices.

What to watch: Expect more equine media, brands, and practitioners to center supplement decisions on forage testing, ration balancing, and quality-assurance markers rather than broad, one-size-fits-all recommendations. (aaep.org)
