Rated 5 out of 5 by from Great Product To Aid In Digestion! My horse, Lucky, has struggled with bouts of intermittent stress-related loose stool. We do show several times a month in the spring, summer, and fall. The travel and overnight stays seem to bring on loose stools. Since adding BioEz to Lucky’s SmartPaks, he has less loose smelly stools and his coat has improved, as well as energy levels. The ease of adding the BioEz right into his SmartPak strip makes it convenient for the barn staff and gives me peace of mind. I love this product. It's easy to top dress and my horse eats it with no problems. Although I am mostly concerned with Lucky’s hindgut support, this all-natural supplement promotes healthy digestion and hindgut function! I have noticed better coat quality, attitude, and nicer overall appearance on my horse using BioEz and will keep him on it no doubt!

Rated 5 out of 5 by from Made a difference Was just recommending this product so thought I would write a review. Have been giving this to my horse for about 4 months now. Saw a notable difference in about 2 weeks. Now it is part of his general care. He is happier. Calmer. My stall manager and trainer have commented how “happy” he is. Give it a try for a month.

Rated 5 out of 5 by from Great product for a reasonable price My Appendix gelding tends to have loose, watery manure in the winter. I assumed this is because of low quality pastures and feeding more hay. I tried several other products including Probios, SmartGI, and SmartDigest and nothing cleared up his issues. He has been on BioEZ for 5 weeks now and looks great! Manure is forming as it should, and he’s put on a few pounds! It took about 3 weeks to see results. This supplement does has an odd smell in my opinion. This horse is a moderately picky eater so I did wet his food to get the powder to stick. But mostly I am grateful that I no longer have to wash poo off of a grey horse’s bottom everyday!

Rated 5 out of 5 by from Great product This stuff is amazing, I had a horse with loose stool (kinda like cow patties) , started him on this stuff, along with the paste (1 tube) , then to 1 scoop of powder only in am and pm , his stool is looking more normal now.

Rated 5 out of 5 by from Senior Horse Had excellent results with older horse that was showing stomach discomfort. Tried ulcer treatment that didn't work and then figured out she was just not producing enough enzymes to comfortably digest her food.Thank you for having a quality product. I highly recommend this product.

Rated 5 out of 5 by from great option My horse seemed to be having some trouble with his digestion and this product was suggested. It has had a wonderful effect and he is much brighter and gut seems much improved. In the beginning I had to add a little molasses on top to insure he would eat it.
