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!

Unfortunately, neither of my horses would eat this supplement. I have one picky eater, however, my other one who will eat anything refused his grain with only a few pellets of this supplement added.

I love this Oil, but the new packaging is a disaster. I used to put a pump on the old packaging and it worked great. Now I'm emptying the pouches into other containers and it is SUCH A MESS. I lost a 1/4 of the oil on the floor. I get that you want to reduce the amount of waste, but at least the other containers you could feed right out of and reuse. When feeding to multiple horses it is hard to portion out of the pouches. Also, the oil on the bottom gets all hard and chunky in this pouch. You can shake the hard containers with some water to mix it up but not this. Please fix the packaging!

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.

Optimal Digestive Health really helped initially with my horse's free fecal water syndrome. After 1 month, there has been a bit of a return of the problem but nowhere as severe as prior to using this product.

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.

Very satisfied with customer service, reduce price on your product when choosing the option for te-occurrence and best of all free delivery. It appears she is eating it but too early to know however if she does not like it that is not your fault! Product has everything in it for her need. Thank you
