Welcome to Mad Barn. We do things differently.
I started Mad Barn after years studying nutrition and working with horses. As a grad student, I saw great research being done but little change in the feed industry. Innovations often didn't make it into barns where they could help horses. I wanted to fix that.
Mad Barn was created to take the best science, turn it into practical solutions that improve the health of horses, and reinvest proceeds into research.
Our mission is to deepen our understanding of equine nutrition and physiology, and to share that knowledge with you so you can make the best choices for your horse.
When you choose Mad Barn, you’re not only giving your horse the very best nutrition, you’re also funding research that advances equine health, performance, and well-being.

CORE
Our CORE line-up of Mad Barn products is designed to provide optimal daily nutrition for your horse and cover their essential vitamin and mineral requirements.
Choose our best-selling Omneity® Pellets, which deliver complete nutrition with 100% organic trace minerals, B-vitamins, digestive enzymes and active yeast cultures.
For horses with metabolic concerns, choose AminoTrace+, formulated with elevated levels of key minerals and antioxidants to support insulin sensitivity and balance excess iron.

From W-3 Oil for cool calories and a shiny coat, to NOCR for respiratory support, MSM for joint health, and Performance XL to restore electrolytes lost in sweat — these formulas work together to keep your horse performing at their best.
