Top 6 Equine Vitamin and Mineral Supplements in Canada for 2026: A Vet-Recommended Guide to Filling Forage Micronutrient Gaps
Broad-spectrum equine vitamin and trace mineral supplements are formulated to fill micronutrient gaps common in forage-based diets and to support overall health, immunity, and metabolic function. In Canada, where pasture quality and hay mineral content vary by region and season, owners favor formulas that are backed by veterinary or nutrition science, use bioavailable mineral forms, and offer clear dosing for different classes of horses. Buyers also look for palatability, Canadian sourcing or manufacturing transparency, and products suitable for horses with metabolic sensitivities. The category ranges from single-nutrient boosters, such as vitamin E or selenium, to complete multivitamin-mineral blends designed to complement forage while helping maintain hoof integrity, immune resilience, muscle function, and metabolic balance.

Omega Alpha Biofos Liquid Calcium Phosphorus Supplement
Omega Alpha Biofos Liquid Calcium Phosphorus Supplement is a specialist formulation focused on delivering the correct calcium-to-phosphorus balance for bone health, growth and recovery — a technical advantage when addressing skeletal or developmental needs. Rather than replacing a broad multivitamin, it is most effective used alongside general liquid vitamins (like Finish Line or Purina) to correct specific mineral imbalances in a targeted, cost-efficient way.

Perfect Prep EQ Gold is a calming and focus paste for horses, not an electrolyte or mineral supplement — the 60 cc oral syringe carries a blend of amino acids, vitamins and herbal ingredients, and the maker positions it as the longer-acting option in the line, with one to two doses per tube. That makes it the odd product on this page: it belongs to the pre-competition shelf by use rather than by nutrition, so it sits alongside an electrolyte paste rather than substituting for one. Treat "show safe" as a marketing phrase and not a ruling — check each active ingredient against Equestrian Canada or FEI prohibited-substance rules for your discipline before you use it at a competition.

What the Research Says: Practical Science Behind Vitamins and Minerals for Horses
Research and industry guidance show that targeted vitamin and mineral supplementation can correct documented deficiencies from forage, support immune and neuromuscular health, and improve hoof and coat quality when used appropriately. Key references used by equine nutritionists include the National Research Council (NRC) nutrient guidelines, university extension studies in Canada and the United States, and peer-reviewed trials on specific nutrients like vitamin E, selenium, and chelated trace minerals. Evidence supports testing forage and blood levels to guide supplementation, and warns that fat-soluble vitamins and selenium have toxicity risks if overdosed. Overall, the best outcomes come from products matched to the horse's diet, life stage, workload, and health status.
Forage variability matters: forage and hay mineral content often fall short of NRC recommendations in parts of Canada, creating a need for targeted supplementation.
Vitamin E and selenium: trials and extension guidance show vitamin E supports neuromuscular and antioxidant function, and selenium combined with vitamin E helps prevent deficiency-related muscle disorders in selenium-deficient regions. However, selenium overdose is toxic, so dosing must be guided by forage and blood testing.
Chelated minerals: multiple studies report improved absorption and tissue retention for organically bound (chelated) trace minerals versus inorganic salts, which can benefit hoof, skin, and immune outcomes.
Copper, zinc, and manganese: these trace minerals play documented roles in hoof and connective tissue health; imbalances or deficiencies can impair horn quality and wound repair.
Vitamin D and calcium balance: vitamin D status influences calcium metabolism and bone health; supplementation decisions should account for dietary calcium to phosphorus ratios.
Metabolic function: certain minerals and nutrients, including chromium and magnesium, have evidence suggesting modest benefits for glucose regulation in metabolically challenged horses, but results are variable and should be integrated with diet and exercise management.
Testing first: forage analysis and targeted blood tests (vitamin E, selenium, copper where indicated) provide the most reliable basis for safe, effective supplementation.
Safety guidance: follow label dosing, avoid combining multiple fortified feeds that could lead to excesses, and consult a veterinarian for pregnant mares, breeding stock, or horses with metabolic or renal issues.
