Control Chronic Digestive Problems
With a Proven Solution

Some horses deal with ongoing digestive issues like ulcers, colic, colitis, diarrhea, loose stool, gas, weight loss and bloating.

These symptoms are ALL caused by a digestive disturbance. It could stem from performance, training & travel stress, old age, social stress, hot feeds, poor quality feed, antibiotics, illness or surgery.

It took several years to perfect our Probiotic Pellets.

The pelleting process requires heat - and heat kills probiotics. BTW, All pelleted horse feeds are required to go through heat exposure above 200 degrees to kill salmonella, if your feed claims to have probiotic, they are no longer alive and able to work.

This means you MUST use a supplement if you want the benefits of probiotic.

So... how did we do it?

First - We discovered a pelleting process that utilizes a cooler method than others which allowed the probiotic to survive.

Then - We already microencapsulated our probiotic to provide extra protection during transport and the gastric acids, this proved to also help the probiotic survive the pelleting process.

Finally - We also lyophilize the probiotic strain, which is a dehydration process to keep the probiotic alive until it's exposed to the moisture in gastric juices of the hind gut. And this combination means that your horse receives the healing goodness of the probiotic when finally given.


  • Probiotic - Saccharomyces boulardii, the most researched and proven yeast based strain of probiotic for use in horses.
  • Prebiotic - Also known as MOS, is food for your horse's natural microbes to get them back on their feet and fighting bad pathogens.
  • L-Glutamine - An amino acid that the intestinal lining uses for health and reduce inflammation of the gut wall.
  • 100% Natural Alfalfa Meal - A natural flavor horses love.


  • Weanlings & Yearlings: 1/2 or 1 scoop a day on feed, or as directed by veterinarian.
  • Adult & Older Horses: 1 or 2 scoops a day on feed, or as directed by veterinarian.
  • Mares: 1 or 2 scoops a day on feed started 45 days prior to foaling, or as directed by veterinarian.
  • Foals: Use Probiotic Paste or Foal Probiotic.
