Eddie struggled with weird poop for a while after I first bought him. ProBios helped some, but MadBarn’s Optimum Probiotic really set his GI tract right. Along with Three Amigos, Omneity, and W-3 Oil, he’s probably the best looking big Thoroughbred I’ve ever seen, and my vet agrees. We love MadBarn!

The probiotic works amazing !!!

I was happy to receive this product with an order as part of a special deal. I love having it on hand for after worming or during stressful times for the horses.

Been using now about 2 months her coat blows even when she's dirty not quite sure about everything yet but I'm happy

Great customer service! Thanks 🙏

This product is amazing! My horse was having “mashed potato poops” and after 4! Days on your probiotic he started having normal looking stool! Thank you for making it!

Package arrived quickly. I have been giving it 1x daily for about 6 weeks. Noticed some improvement in diarrhea first week, and some more the second week. Horse has had some intermittent bouts of diarrhea but way more effective than the probiotics I tried last spring and summer. Will buy again next year and start before his spring time issues start.

It solved the digestive issue with our Shetland.

My horse got runny poop from this

Amazing results and fantastic service. i am a client for life!
