I've tried a bunch of very expensive products....and nothing worked on my 30ish rescue. ... Until I found BioEZ. This stuff is awesome. He can finally keep his weight on, and his body language and attitude tell me that I'm doing something right with regards to digestion. Seasonal hay changes used to really upset his system...diarrhea. This BioEZ has really made a difference. Thank you to the makers. I recommend !!
