Great product, easy on the bank account for the quality, and my horse loves it!

After starting my horse on 3:1 Copper and Zinc, I was skeptical if I could really help my horse. He got really sun bleached and was looking terrible. After almost 6 weeks on 3:1 Copper and Zinc he's looking like a new horse and for the first time ever he's getting dapples!!

The product arrived as promised

The Optimum Probiotic does all it says and more. I bought it originally for one of my donkeys who was recovering from a severe illness and had been on a lot of medication. I now have all 3 horses and 2 donkeys on it daily and have no issues with stomach upset or loose stools. They all look wonderful, which indicates to me that their stomachs are working well and optimizing their feed. And an added bonus is that the service was great and I received the product quickly. Highly recommend!

I just can’t say enough great things about this company! Excellent products and excellent customer service. My order last week was missing a box when it arrived. The shipping company had me on hold for hours and I contacted MadBarn customer service. She sent me out another one right away and it arrived in less than 48 hours!! Thank you ! 5* service!

I adopted an 22 yr old gelding who was having troubles with diarrhea, I've tried a few supplements but nothing seemed to make it go away. At first my gelding didn't like the taste of this supplement but he would eventually eat it when he realized he wasn't getting anything else, he now eats it no problem and his diarrhea has seem to have cleared up. I will be keeping him on this as I do not want it to return. Great supplement.

Since adopting our OTTB in January, we researched different supplements to aid in his growth and development – we chose Mad Barn and are thrilled with the results. We use Omneity and W3 oil in addition to his regular diet and it has made such a wonderful difference in his coat, weight management, and feet. I highly recommend their products. Service is off the charts whether assisting in choosing the right supplements or getting them to you in a timely manner after ordering online.

Mad Barn has great customer service, ships out on time, and my metabolic horses are doing well on this formula. My gelding didn't appreciate the taste at first so I just added it in slowly, gradually upping the qty and hat seemed to do the trick.
