Ingredients and why each is included
Amounts below reflect the current formula per one-scoop dose. Sodium chloride and potassium chloride perform most of the direct electrolyte work, while the remaining minerals and GastroCell™ ingredients round out the formula.
Primary electrolytes
- Sodium Chloride, 1,656 mg: supplies sodium and chloride, two major electrolytes lost through sweat. They support normal fluid balance, muscle contraction, and nerve function.
- Potassium Chloride, 1,152 mg: supplies potassium and additional chloride to support normal fluid balance, nerve signaling, and muscle function.
Supporting minerals
- Magnesium Oxide, 192 mg: supplies magnesium for normal muscle and nerve function and energy metabolism.
- Zinc Sulfate, 60 mg: supplies zinc used by normal enzyme systems and involved in maintaining skin, coat, hoof, and immune function.
- Manganese Sulfate, 9.6 mg: supplies manganese involved in normal enzyme activity, connective tissue maintenance, and bone metabolism.
- Dicalcium Phosphate, 466 mg: supplies calcium and phosphorus for mineral balance, normal skeletal function, and energy metabolism.
- Ferrous Sulfate, 26.88 mg: supplies a small amount of iron involved in normal hemoglobin formation and oxygen transport. Hydro-Lyte® is not positioned as an iron supplement or blood builder.
GastroCell™ Blend
- Vitamin B1 (Thiamine Mononitrate), 50 mg: supports normal carbohydrate metabolism and nerve function.
- Magnesium Chelate, 114 mg: provides an additional magnesium source for normal muscle, nerve, and metabolic function.
- Betaine HCl, 840 mg: supplies betaine, an osmolyte involved in cellular water management, and complements the GastroCell™ digestive-support portion of the formula.
- L-Glutamine, 170 mg: supplies an amino acid used by intestinal cells and other tissues to support normal digestive-tissue maintenance.
Flavor and formula protection
- Natural antioxidants and rosemary: help protect ingredients from oxidation and maintain product freshness.
- Apple and molasses flavor: supports palatability in the horse's normal feed.
Formula update: Sodium fluoride has been officially removed from the Hydro-Lyte® formula. Some packaging may still display the previous ingredient panel during the label transition.
Important: Hydro-Lyte® contains potassium chloride. For a horse with HYPP or a veterinarian-directed potassium restriction, confirm suitability with the treating veterinarian before use.
