History
Mad Barn was founded with the goal of improving equine health through better nutrition. According to the company's own account, it did not start as a conventional supplement business; instead, its founder formulated a mineral and vitamin premix out of a desire to provide the best nutrition for their own horses. The founder found that well-formulated products on the market were either prohibitively expensive or contained ingredients they did not want to feed, and that many supplements were formulated to target a specific ailment, resulting in high levels of a few nutrients and none of others, creating dietary imbalances. The solution was to create a completely balanced mineral and vitamin premix. After seeing improvements in the condition and performance of horses in their care, the founder began sharing the product with others, which led to the creation of Mad Barn. The company has since grown into a full-line equine nutrition brand offering supplements across many health categories, including vitamins and minerals, joint health, gut health, hoof health, skin and coat, metabolic health, mood and behavior, performance, topline and muscles, respiratory health, weight gain, and immune system support. Its flagship products include Omneity® Pellets and Omneity® Premix, AminoTrace+, Visceral+, w-3 Oil, Optimum Probiotic, Optimum Digestive Health, and Performance XL Electrolytes. Mad Barn differentiates itself through a mission-driven approach: it funds equine nutrition research, develops technology and feeding solutions, and provides education and support to horse owners. A central service is its free diet analysis, which the company says has helped more than 57,000 horses. The company also publishes Mad About Horses, a free seasonal magazine with English and French editions, featuring articles from its nutritionists, veterinarians, and equine experts. The magazine is distributed to customers with orders and through retailers across North America. Headquartered in Ontario, Canada, Mad Barn serves the North American market, with a significant customer base in the United States. It remains a privately held company. Its team includes veterinary nutritionists and equine nutritionists, such as Dr. Eleanor Kellon, VMD, and Dr. Ana Mesa, PhD, who provide expert guidance to customers. The company states that all of its activities are funded through product sales, tying its commercial success directly to its research and educational mission.
