Purina MQ Systemiq is a pelleted live & active equine probiotic supplement for all horses. For over a decade, Purina has been studying the equine microbiome to help horse owners unlock new insights into their horse's health. We looked beyond the usual expectations of what a probiotic can do. The unique and patented probiotic technology in Systemiq survives when other bacteria strains don't, remaining live and active through manufacturing and the horse's gastric environment. It has a systemic effect in your horse, helping them overcome challenges such as exercise or occasional gastrointestinal stress. It is one more piece of the puzzle to help protect horses with sensitive systems and elite athletes alike. Systemiq probiotic supplement provides proven benefits backed by science.

  • Patented Probiotic Technology: Shown in research to support optimal digestive and immune function in horses, when fed daily
  • Remains Live and Active: Proven to survive through manufacturing and the environment of the digestive tract
  • Research Proven: To support normal hindgut health and fecal consistency in horses stressed from exercise or other activities
  • Optimizes the Microbiome: Supports normal recovery after exercise and occasional gastrointestinal stress
  • For Horses of All Ages, Including Pregnant and Lactating Mares
  • Competition Friendly
  • Developed by PhD Equine Nutritionists

Almost a miracle

16 days ago
I started feeding this to my gelding a few months ago. He has always had gut issues horrible watery poop a lot of the year not just winter. Ive tried so many supplements and had a ton of tests done by the vet and pretty much nothing worked. Now my horse poops like a normal horse his butt isn't covered in yuck...and i know he feels so much better. I now have it on monthly auto ship and will continue using it forever for him.

Yes, I recommend this product.

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.
