Stephen Duren, PhD, MS, PAS, completed his Bachelor of Science in animal sciences at the University of Idaho. He earned a Master of Science and a Doctor of Philosophy in equine nutrition and exercise physiology from the University of Kentucky. His research focus centered around feeding fat to racehorses and changes in blood flow distribution in fed and fasted horses during exercise.

Duren has now formed Performance Horse Nutrition, LLC, where he consults with feed manufacturers and horse owners throughout the world. Duren has owned horses his entire life and truly understands the connection between diet and performance. He has owned competitive horses and understands the investment of time and training and realizes that diet should be a factor that helps the horse, not limits the horse.
