GastroFix TM is a gastrointestinal nutritional support supplement designed to help assist your horses health  formulated with ingredients to safely bind mycotoxins, aid in fore and hindgut health and promote optimal absorption of essential nutrients, and healthy and strong intestinal membranes.**


Natures Farmacy's GastroFix contains bioavaialble Marine Calcium and Magnesium - Hind gut acid buffers and stomach alkalisers - for gastrointestinal and Hind gut PH health.


Mycosorb A - Toxin binder with Algae - to bind mycotoxins that impair health and performance through reduced feed conversion, and nutrient uptake. Ingesting Mycotoxins may also lead to impaired reproductive performance and depressed immune system responses.  Many well known gastrointestinal products  don't disclose they use clay and charcoal-based toxin binders. Clays and Charcoals can bind good nutrients, wormers and medications and impact their effectiveness - they are best used short term only not in feeds containing major nutritents or within four hours of other medications.


Actigen - concentrated pathogen binder and prebiotic - is used as a food source for beneficial bacteria that are found in the natural flora of the digestive tract. It is an indigestible compound that binds pathogens such as E. coli and Salmonella that are present in the gut.  Actigen activates the immune system.


L-Glutamine and L-Threonine are essential amino acids that protect the gatrointestinal lining and improve nutrient absorption, They strengthen the intestines to maintain maximum surface area for nutritent utilisation. The immune system needs  L-Glutamine to protect from illness and tissue damage.  Natural stores may be depleted during gastrointestinal disease,  such as colitis or ulcers, malnutrition, infection or intense exercise and stress.  L-Threonine assists mucin production which forms a protective barrier for the gut wall.    Deficiency slows regeneration of the gut wall and depresses production of mucus,

    "I Have 2 horses on the GastroFix. The original, Greenie who is improving heaps and education. And I discovered the 31 year old's gut likes it over the many other products I have tried to settle his gut and chronic diarrhoea. He is now picking up in condition too."

    "Just wanted to let you know that we had our mare scoped today at the local vets. He commented on how well her gut looks for a racehorse and one that is uptight. She only had a few small ulcers which we will treat. We just love your GastroFix!"
