I tried Optimum Digestive Health following some colic issues a couple of years ago that were tough to resolve. My vet recommended another product she had first-hand experience with but it was too expensive. After researching, I discovered this product had the same effective ingredients without the fillers and sugars of the more expensive product. The colic episodes disappeared after about 6 weeks. I tested it last summer by removing the Optimum for a couple of months but my horse began acting like he was uncomfortable again so I put him back on it. We're now at a point where he is okay without it in the summer, but I'll be adding it back in over the winter just to be safe.

Great product for the price. I saw a difference with my horse.

This has really helped our horse keep his fecal water syndrome under control. Great product!

This is the only product I have tried that keeps my sensitive horse's hindgut balanced.

I absolutely love this supplement! I have seen a marked improvement in my mare’s body condition and enthusiasm for hay since being on this hindgut support. She’s gained weight nicely and is calm and happy. 10/10 recommend!

I started my two senior geldings on Optium for two separate reasons. One horse has “cow paddie” manure and a pot belly. The other horse had frequent, excessive gas. Within a week I started to see results with both horses. After a couple months I stopped feeding them Optium thinking they were over their symptoms, but their symptoms returned. One of my horses is very picky so I had to start with a very small amount and gradually increased it. A few low sugar treats mixed in his feed helped introduce it to his diet. I plan on keeping my horses on Optium.

Super customer service. When horse continued to leak manure, they suggested I administer an extra 1/2 scoop. It worked! Thank you!!!

My mare suffered from diarrhea or soft stools and gassy stomach for months. I tried several other digestive aid supplements but none worked until I tried Optimum. Now her stomach is back to normal. Optimum was also more affordable than some of the other supplements that I tried. My mare and I are happy with Optimum and Mad Barn service!

I have a mini horse that had diarrhea on and off and we couldn’t find anything that worked until MadBarn Optimum. After adding to her feed we saw results in a couple weeks. It’s been a few months now and no diarrhea and our little horse is acting like herself. Highly recommend this product!

Awesome
