Has anyone tried NeutraBac PH? It looks almost the same as zesterra and is a little cheaper. 

I've used zesterra for years with good luck, the ingrediants look almost identical between the two.

I started using Healthy Gut by Simply Equine. Very similar ingredients and much cheaper. 

I switched form Zester to NeutraBac mainly because the NeutraBac has the coloidial silver in it. So far I like it, haven't noticed and negative effects since switching.

Thanks, I've hesitated mostly because of the dealer for NeutraBac, but I might have to give it a try. 

Have you been using Healthy Guy to treat or prevent?  What kind of results have you seen??

Two Nickels – I have been using Healthy Guy to prevent. I use it under times of stress (hauling, weather change, sickness, entering, going off food or water and on set of colic) I have had the same results as Zesterra. Horses relax and go back to eating and drinking normally. I have never used Healthy Guy to treat ulcers yet.

I use Sadie Ricks, she is in Northern Nevada. She is on Facebook.
