ProN8ure (formerly Protexin) Probiotic Powder

Notify Me When Available

In late 2020 International Animal Health began rebranding Protexin to a new name  "ProN8ure". The actual product remains the same and the only thing that has changed is the name.


  • Establishment of beneficial gut microflora
  • Suppression of E. Coli Salmonella & Aeromonas spp
  • Treatment and control of scouring and diarrhoea
  • Improved digestibility of feed
  • Improved growth and feed conversion
  • Reduced digestive upsets
  • Enhanced animal health
  • Re-establishment of gut microflora following antibiotics, wormers or vaccination
  • Reducing stress (stress disrupts normal intestinal balance)
  • Safe, non-toxic and residue-free.
Stress, in all forms is one of the major causes of disruption to the normal balance of microflora in the gut, allowing proliferation of pathogens. Loss of appetite, picky eating, scouring, poor condition and changes in temperament are some of the less consequences. Stress is easily induced with some common causes being: changes in diet, heavy work or training, temperature extremes, breeding, transportation, worming, vaccinations and changes to environment. Use of PROTEXIN® in these circumstances protects horses from negative intestinal changes while improving digestive efficiency and general health.

Antibiotics are particularly harmful to gut microflora, leaving animals susceptible to re-infection. PROTEXIN® should always be administered following any course of antibiotics.

The digestive system plays a vital role in the health, vigour and performance of horses. Its correct functioning is dependent on the level and balance of bacteria and yeasts called microflora. Microflora have the major role in breaking down indigestible nutrients, in the synthesis and absorption of vitamins and minerals, in stimulating the immune system and in preventing the proliferation of pathogens in the gut.

Foals are born with a sterile gut which is rapidly colonised by both beneficial and pathogenic bacteria. A fine balance exists which can easily be disrupted, leading to scouring, ill thrift and other problems. Feeding PROTEXIN® from birth protects the foal from pathogens, improves digestive efficiency, enables better utilisation of feed and makes the transition from milk to solid feed easier.

All horses benefit from PROTEXIN®'s ability to stabilise intestinal microflora, maximise gut health and resist the effects of stress.

Great product

I've been giving my 11 years old boy this for a few weeks. It seems to be helping not only with his digestion but also with his breath and coat. I will definitely repurchase it.

Elaine Russell (Melbourne, AU)

Great product but seems difficult to get in larger quantities sometimes and delivery times slow (not your fault) Helps the older horses and 2 who windsuck!

ProN8ure - formerly Protexin

I've been feeding this on and off to multiple horses over the years. Great to get their guts back in balance particularly after worming or antibiotics.
