NAF GastriAid Gut Balancer

NAF Five Star GastriAid is the must have daily supplement for total gut health. Targeting digestion from the point of ingestion, Five Star GastriAid promotes correct function and gut integrity from foregut to hindgut, giving your horse a happy, healthy tummy.

– Saliva support
– Helps balance pH levels and offers acid ease
– Muscosal integrity
– Promote nutrient uptake
– Active live culture

Five Star GastriAid commences its journey with saliva support, before releasing natural buffers to balance pH. Promoting the health of the small intestine itself has a direct benefit to nutrient uptake, supporting wall strength and elasticity. Activating strong biotic nourishment for the hindgut, live cultures provide recolonisation to underpin the vital equine fibre fermentation process. Five Star GastriAid contains NAF Five Star BioG, a unique synergistic complex that brings together the latest in evidence based nutritional solutions. Combining live probiotic yeast, prebiotics MOS and FOS and new postbiotic metabolites, Five Star BioG supports total gut health right along the gastrointestinal tract. Whatever the challenge, Five Star BioG works in synergy within NAF’s targeted functional supplements to support your horse’s unique microbiome from fore to hindgut, improving total gut health, digestive efficiency and general wellbeing. Feed Five Star GastriAid for total gut health.

5 My big 17.2hh elderly horse who is prone to ulcers ...

Review by , 1 year ago

My big 17.2hh elderly horse who is prone to ulcers has been on this for around 3 weeks after having to come in more due to the poor wet weather. He has quite a nervous disposition which is reflected in his bowel movements! Last year he lost so much weight I had to have him in a crew yard on a farm as he wouldnt settle in a box. This year he has come in and been put on this straight away. So far he is holding his weight really well, his droppings are normal and he is so quiet we barely even know he's on the yard which is wonderful. It has completely changed his life for the better - super impressed !
