I am so impressed with this product. Finally, a well balanced supplement, and at such a FAIR cost!!

Just what I was looking for I was looking for an affordable zinc & copper supplement to counteract our high iron pasture and water. This fits the bill perfectly, and I love that it will be shipped automatically. The horses are eating it happily mixed in with a handful of oats and some apple cider vinegar. Not sure if they'd be a fan of it plain ;) I've only been using it about 3 weeks, but I swear the thrush I've been battling all winter is looking better already!

Started using this after using the Equitop Myoplast (sugar coated spirulina), great source of protein and a lot cheaper than the myoplast. My horse has developed so much topline since starting on all the Spirulina supps. Only downside is that it's a little messy. But that is a small price to pay. Thank you to MadBarn for creating awesome and affordable products!

It's hard to find quality probiotics for horses that don't have a lot of other fillers in them and require a huge pail. Mad Barn's Optimum Probiotic is a rare gem. In fact, when the box arrived (2 days later!), I first thought there was a mistake because the package was so small. Nope! It's just so concentrated that it only requires a very small amount. I bought it to help with a detox for one of my mares and ended up putting the whole herd on it (and our donkey friend). They're all thriving - despite the cold temps and deep snow right now, they're all back to running, rearing, and playing joyfully. Thanks Mad Barn!

My thoroghbred stays [redacted] free as long as I keep her on Visceral - great product. And the company is great at shipping your orders right away. Love dealing with MadBarn *** Parts of this review have been redacted to comply with Health Canada Regulations ***

My mare in the winter has stall anxiety and gets ulcery, I switched her to a sugarless grain and have put her on visceral! I have seen a wonderful difference in her. She is calmer when you walk her outside and loves coming inside at night!

My mare has been on this product for 10 days so far. I have been able to reduce her Hoffmans Balance R pellets and she likes this product. I have noticed more energy in her walking time and her feet more comfortable. She is also getting amino trace with her IR Supplement. My farrier and I will monitor her hoof condition as she continues on her supplement Thanks you Mad Barn

Cleared up my mare's liquid stool quickly.

My girls have been on the IR support for about a week now. They started showing improvement within 3 days! This has worked for them, and hopefully turned back the progression of cushings! They weren’t crazy about the taste but now they are fine with it. Thank you MadBarn!

Overall happy with this MSM. The package I received had a tear in the bag so lost some product which was disappointing. Likely a one off case so would purchase again in the future.
