Scott Cieslar Horse NutritionistWelcome to Mad Barn. We’re a different sort of company.

On the exterior, we may look like a lot of other supplement companies out there, but let us assure you, we are not.

Our primary purpose is not to convince you to buy a product, it’s to deepen our understanding of equine nutrition and physiology and then share that information with you.

We aim to improve the well being of your horse by providing Crazy Good Nutrition at a fair price. The horse is an integral part of human history – don’t we owe them the very best?

Our CORE line-up of Mad Barn products are designed to provide optimal daily nutrition for your horse and cover their mineral and vitamin requirements.

Choose between our best-selling Omneity Premix (in powder form) or Omneity Pellets containing 100% organic trace minerals, B-vitamins, digestive enzymes and active yeast cultures.

For horses with metabolic needs, opt for AminoTrace+ which brings mineral ratios into correct balance to combat high iron and fight inflammation.


We offer three GUT formulas to improve your horse’s health from the inside out. Addressing imbalances in your horse’s microbiome can go a long way in supporting nutrient absorption and alleviating gastrointestinal complaints.

For horses diagnosed with or at risk of ulcers, our clinically-studied Visceral+ supplement is proven to work.

If you’re looking to prevent digestive upsets, consider our Optimum Digestive Health Pellets. Or check out our Optimum Probiotic for a low-cost high-CFU equine probiotic.
