I bought this a month ago and it has definitely helped with water in my mares stool. Stool is still on the soft side, but not wet

Works for my horse

a year ago
The process was ok. I'm more impressed with the product because it has been the only thing to help my horse have well formed / non watery manure.

Yes, I recommend this product.

First product that worked for Fecal Water Syndrome

a year ago
This is an amazing product! I had the MQ Biome testing done and put my horse on MQ Systemiq with the hope of treating his Fecal Water Syndrome. At around 45 days on the supplement his FWS ceased. He's been clear now for about 2 months. My vet recommended feed and hay changes, performed bloodwork, had an allergy panel run, tested for parasites, and recommended numerous gastro supplements and probiotics. We tried so many things over the past 4 years and nothing worked. That is, until the MQ Systemiq - it is the first thing that has actually worked! I HIGHLY recommend this product.
