Five Star GastriAid provides gut nourishment from foregut to hindgut. A comprehensive formula to help ensure each individual enjoys a happy, healthy tummy.

Each time you feed GastriAid, it begins its gut journey by supporting saliva production. This is essential for the later processes, which includes helping to regulate stomach acid and promote thermoregulation. It then helps balance pH levels in the stomach, encouraging a healthy foregut environment. Its next focus is on the small intestine; helping to ensure your horse can absorb nutrients effectively by promoting a healthy lining. Finally, thanks to the inclusion of our Five Star BioG, the hindgut is nourished with live culture to oversee correct and efficient fibre digestion.

Five Star BioG combines a useful food source in the form of prebiotics, helping to promote good microbial colonies. We also include a live yeast probiotic to help stimulate healthy numbers of good bacteria, while postbiotics provide beneficial metabolites to support immune function, and help prevent bad bacteria from taking control of the hindgut.

Clean Sport: GastriAid is audited under the BETA NOPS Scheme as suitable for FEI competition. Check local authorities if racing or competing internationally.
