Performance Horse Nutrition® (PHN®) was founded in 2002 by Dr. Stephen Duren. The goal of PHN has always been to advance the “science” of feeding horses, and equally important to disseminate that science to our clients in the simplest, most straightforward means possible. PHN prides itself on having trained Ph.D equine nutritionists that are not only scientists, but also horsemen. We understand how to feed horses and our feeds, feeding recommendations, articles and seminars reflect that understanding.
