Purina® Systemiq™ Probiotic Horse Supplement | 2 Pounds (2 LB)

My horse has fecal water syndrome. My vet suggested I try this product. The second day I noticed a difference. No more cleaning her up every day. I have backed off the dose just a little and it's still working. Great stuff.

Amazing product see results within 15 days. I have a about 6 horses on this product

This stuff works! I had a new horse come in with runny poop that wouldn’t clear up. I put him on this and his poops are fantastic!

Working on solving FFW for a "new to me" 8 year old. The condition is not severe but she has had it several years prior to me getting her end of December 2024. I submitted a fecal test to Purina the end of January 2025 and started their MQ Probiotics at that time. I have not seen an earth shattering result first month of administering so I am going to try a 2nd month in order to consider the time needed to reverse a gut condition that has been off for several years. I like its easy to use, tasty to her. It's a bit costly but less expensive purchasing on Amazon than directly from Purina.

Great product and fast delivery

My horse has been struggling with loose stool. It took some time, but after three weeks I started noticing a difference in my horse’s feces. This product is a bit pricey though, and I wish it came in larger containers than 30-day servings.

This was told to my by a vet that boards at my barn to try. It’s a newer product and my horse occasionally has issues with runny poop. This has been AMAZING. I’ve tried many different gut things ha for him in the last few years and out of all for the price it’s a 10/10

I usually love Purina products, but this did nothing and actually made my horses worse. I gave it over 2 weeks and their stools did not improve. I wouldn't waste my money on this product again.
