My 25 yo TWH gelding is doing well with Spirulina. It has really helped his allergies and overall ability to navigate the dust, pollen and bugs. I plan to keep him on this supplement. It took a few weeks for him to adjust to the taste, now he eats this very well with his meal. I do recommend.

Love it

I started using Mad Barn Visceral+ alongside Optimum Digestive Health for my senior mare who struggled with ongoing gut instability. Since putting her on this combination, I’ve seen a clear and consistent improvement, her gut has stabilized and the diarrhea is completely gone. She’s noticeably more comfortable overall. This has made a real difference for her digestive health, and I’m very pleased with the results.

I absolutely love this vitamin E supplement. It’s easy to administer, well priced and a great addition to my feed program in winter when horses are not on pasture.

Older horse has been maintained weight better so far this winter.

Used it in conjunction with zinc copper to help with my mare's hooves, and both my horses' coats. Hard to specifically say that the biotin was the gamechanger, but her hooves look much stronger, less brittle, and have more elasticity within a few months!Their nutritionist team is also great, it was a bit hard to pin them down initially but they were super helpful creating a plan that would work for my little herd. Definitely lends additional confidence in their products to know the company takes such an active interest in the clients' needs.

I contacted Mad Barn to do a feed analysis for our 27 year old paint horse who had recurring diarrea and at times fecal water syndrome. I had a really fast response with great advice. Part of the prescribed feed was the Optimum Digestive Health along with Amino Trace. The results have been amazing. This horse, who has suffered particularly in the winter months with diarrea, is now doing incredibly well.

I love it it is the best for both of my horses!

Psyllium is working great for us! I do adjust to his needs, increasing/decreasing when needed. I love that I can send an email to for another order, and within a day its processed and shipped.My horses are looking great on Madbarn products! I am very happy with the products and the customer service!
