Hi. I have a Horse with a very sensitive gut. The vets have ruled out anything 'major' eg ulcers, and have come to the conclusion that he's just sensitive!I have tried a 6 week course of Protexin Gut Balancer but there has been no difference which I'm disappointed about as a lot of people seem to find this helps. I was wondering about a basic yea sacc supplement?What do people think? And if so, every manufacturer seems to have a different way of expressing the amounts of yea sacc in their products so I can't decide which would be best to buy. Any recommendations?Thank you.
