I suspect my OTTB is a bit prone to ulcers. I am not a fan of long term omeprazole use, so once she has finished her new course of pop rocks, I am want to put her on a supportive supplement. Previously I have used SmartGut and was quite happy with it, but it is rather expensive for long term use. I found a reference to Excel (by DePaolo Equine Concepts http://www.depaoloequineconcepts.com/product/excel.aspx) which seems to have similar ingredients and is significantly cheaper. Any thoughts on these two??
