    "Saved my Gelding"

    I have a quarterhorse gelding that had come close to dying due to colic on several occasions. I tried everything and nothing worked. Then I tried Opti-Zyme fed daily with an electrolyte and Equine Senior feed. He has not had colic for over 5 years on this program. I would not be without Opiti-Zyme for this horse.

    "Wow! Helped my horse's diarrhea"

    I have used probiotics before. I have used them within weight supplements, I have also used Pro-bios. Let me just say that so far this is the best one that I have ever used. My 26 year old horse had diarrhea so bad that I had to re-wash a blanket I had just washed. I put him on Opti-zyme within a few days the diarrhea was almost gone, three weeks later it is a thing of the past. So I am hooked, and moving forward all of my horses will be on opti-zyme. Personally I find that probiotics are helpful in reducing feed costs as well.

    "Helped reduce runny stools."

    My TB mare has a very sensitive stomach and has loose stools when not on a digestive supplement. I have used others with success but changed over to this last month. Within a week or so her stools were more solid, so it gets an A+ from me.

    This is a product that I have used for years. Great product & great price. It has been a great help in keeping my warmbloods healthy & happy. Everyone gets it from the old guys to the foals & broodmares. I won't be without it!
