We have stopped the Purina Outlast [not a post]. Over the years, we have tried so many solutions for sensitive horse stomachs: Outlast, ranitidine [Say Aaaah!/Update], Tums. Maalox, yeast [Tiger Whistle], and a variety of additives that Rodney was on when he arrived. We stopped for various reasons, from lack of availability – ranitidine [Zeno] & yeast [not], to lack of results – the initial goops, to wandering off to try new things – Tums, Maalox, Outlast. Maybe we saw minor changes for the good. Maybe we wanted to see minor changes for the good. Nothing definitive.
The answer is UlcerGard. It works. It’s ridiculously expensive. The rest pale in comparison. YMMV.
