Keeping your horse’s digestive system in peak condition is essential for their overall health and performance. The Aviform EGF (Equine Gastric Formula) Supplement is specially designed to support optimal gut and stomach health, particularly for horses prone to gastric discomfort or on low-forage diets.

What’s Inside EGF?

The newly improved EGF formula includes cutting-edge ingredients to provide your horse with enhanced digestive support:

  • Actigen® (upgraded from Bio-Mos®):
    • A second-generation bioactive, mannan-rich fraction (MRF), specifically designed to support gut integrity and balance.
    • Promotes the growth of beneficial gut bacteria while blocking harmful organisms.
    • Builds the foundation of a stable and healthy gut microbiome.
  • Lecithin:
    • Naturally soothes and protects the stomach lining.
    • Supports the production of protective mucus, creating a barrier against excess acid.

Really helps tummy settle when moving to new pasture.
