Buying Guide

Check the primary purpose

Choose supplements formulated for your horse’s needs—maintenance formulas differ from electrolyte powders or acidifiers like ammonium chloride

Compare ingredient labels

Look for guaranteed analysis of vitamins, selenium and vitamin E content, and mineral sources so you can match supplements to forage and hay deficiencies

Consider format and dosing

Powders, loose minerals, and crushed salt blocks offer different mixing and intake control; pick the format that fits your feeding routine and herd management

Evaluate serving cost

Use cost-per-day or cost-per-serving to assess value—higher unit price can still be economical if serving size is small or concentrated

Watch for additional functional ingredients

Some products include electrolytes for hydration or ammonium chloride for urinary acidification—confirm those extras align with veterinary guidance
