Top 5 Vitamin & Mineral Supplements for Horses in Canada (2025) — Vet-Reviewed Options to Correct Deficiencies, Protect Performance, and Give Owners Confidence

Published on Thursday, August 21, 2025

This category covers individual and blended vitamin and mineral supplements for horses — from chelated trace minerals and vitamin E to selenium formulations and premixes designed to correct dietary shortfalls. These products are especially useful for fine-tuning nutrition in forage-based or restricted diets, supporting broodmares, performance horses, seniors, and animals on rations that vary by season or region. Canadian buyers often prioritize proven bioavailability (chelated minerals), clear labeling, traceability, and formulas tailored to local forage variability; they also value veterinarian input, premixed convenience, and safety data to avoid both deficiencies and toxicities.

BEST B‑VITAMIN SUPPORT SUPPLEMENT

Brooks Feed B-Complete Plus

Brooks Feed B-Complete Plus

Brooks Feed B-Complete Plus fills a specialized niche by concentrating on B-vitamins and related cofactors that support metabolism, nervous system function, and stress recovery in performance or recovering horses. Its technical advantage is targeted nutrient density for specific metabolic or behavioral issues rather than being a full-spectrum mineral premix, making it an efficient complementary supplement to broader multivitamin/mineral products on this list. Financially it is typically mid-range and attractive when used alongside a mineral base like Purina or Masterfeeds instead of replacing them.

BEST BUDGET ESSENTIAL MINERAL MIX

Hoffman's Horse Mineral

Hoffman's Horse Mineral

Hoffman's Horse Mineral is positioned as a straightforward, budget-friendly mineral supplement that provides essential salts and trace minerals for basic maintenance and hard-working stock. Its simplicity and low cost make it a practical baseline choice for owners on tight budgets or those who only need a minimal mineral top-up, though it lacks the comprehensive trace‑mineral tailoring and added vitamins found in products like Purina or Mad Barn. As a low-complexity option it pairs well with targeted products such as Brooks Feed B-Complete Plus when additional support is required.

What the Research Says About Vitamin and Mineral Supplementation for Horses

Scientific guidance and clinical studies support targeted vitamin and mineral supplementation when forage or feed does not meet a horse's life-stage or workload requirements. National recommendations (for example, NRC equine nutrient guidelines) are the baseline for amounts; peer-reviewed research highlights the roles of key nutrients — vitamin E and selenium as antioxidants, copper and zinc for connective tissue and immune function, and chelated forms of trace minerals for improved absorption. Evidence also stresses testing (hay, forage, blood) and dose control to avoid under- or over-supplementation.

NRC nutrient recommendations provide evidence-based targets for vitamins and minerals; supplements are intended to fill gaps between intake and these targets.

Vitamin E and selenium act as primary antioxidants for muscle and neurologic health; clinical studies link appropriate supplementation to reduced risk of deficiency-related conditions.

Chelated trace minerals (amino acid- or protein-complexed forms) frequently show better bioavailability in absorption studies compared with some inorganic salts, which can improve biological response at lower inclusion levels.

Premixes and balanced vitamin-mineral blends make consistent dosing simpler for herd management and reduce the risk of mineral interactions when formulated to established nutrient ratios (for example Ca:P balance).

Regional soil and forage variability in Canada can create predictable deficiencies (or surpluses) — testing forage and blood levels before long-term supplementation helps target interventions and avoid toxicity, particularly with selenium.

In Canada, vitamin and mineral supplements are a practical way to correct diet-driven gaps for horses on pasture-limited or forage-heavy rations. The products profiled here — Mad Barn Omneity Premix P, Purina Optimal Horse Vitamin and Mineral Supplement, Masterfeeds Equine Mineral and Vitamin Premix, Brooks Feed B-Complete Plus, and Hoffman's Horse Mineral — cover a range of approaches from full premixes to targeted trace-mineral and vitamin boosts. For most Canadian owners seeking a balanced, traceable premix with strong formulation and lab transparency, Mad Barn Omneity Premix P stands out as the best choice on this list, while the other options remain excellent for specific needs (Purina for broad availability, Masterfeeds for herd feeding, Brooks Feed for B-vitamin focus, Hoffman’s for mineral-specific corrections). I hope you found what you were looking for; use the site search to refine by life stage, ingredient (for example vitamin E, selenium, chelated minerals), or expand to vet-recommended feeding plans.
