HUMIDIMIX is a specially formulated supplement that contains high levels of potassium, chloride and magnesium to encourage drinking and help with:

  • Replacing essential electrolytes
  • Horses recovering from sweat loss due to heat, humidity and intense or prolonged exercise.

The powdered supplement can be added to feed or given in water.


  • High performance horses doing moderate speed work over extended periods (e.g. harness, racing, endurance, eventing, dressage, stock work)
  • Heavy sweaters
  • Horses working in hot and humid conditions
  • Horse prone to ‘tying up’ or ‘anhidrosis’ (dry coat or non-sweating disease)


  • Higher levels of potassium – To avoid decreases in muscle strength and tone.
  • Higher levels of chloride – To help avoid blood alkalosis (hypochloraemic alkalosis), which causes issues such as loss in racing performance, uncharacteristic nervy behaviour and increased risk of tying up.
  • Higher levels of magnesium – To maintain metabolism and musculoskeletal soundness.
  • Ideal balance of electrolytes - HUMIDIMIX replaces electrolytes in proportion to those lost in heavy sweating for immediate correction and performance.
  • Encourages drinking through versatile dosing without the fillers (e.g. sugar, lactose or table salt).
