Immune Booster Plus is a natural New Zealand-made herbal extract designed to support your horse’s immune system, respiratory comfort and everyday vitality.

It is especially useful when your horse is feeling run down, recovering after a seasonal bug, coughing, snotty, low in energy, or needing extra support through winter and changing weather.

Immune Booster Plus may be helpful for horses needing support with:

  • Seasonal immune support
  • Winter wellness
  • Respiratory comfort
  • Coughing or throat irritation
  • Snotty noses or seasonal bugs
  • Recovery after being run down
  • Stamina, vitality and resilience
  • Extra support during weather changes

If your horse has a persistent, severe or worsening cough, breathing difficulty, fever, or appears unwell, please contact your vet.
