Clair Thunes, PhD, founder of Summit Equine Nutrition, describes how an equine nutritionist can benefit your horse. With so many supplement and feed choices available, it is hard to know exactly which products are best for each horse’s individual needs and whether their nutrition is properly balanced. Dr. Thunes has a PhD in Equine Nutrition from U.C. Davis and has worked with a wide range of horses from lactating mares to competitive eventing, dressage, endurance and driving horses. She also specializes in working with Veterinarians to balance the diet of horses with physiological problems such as including insulin resistance and muscle myopathies. Each horse needs to be fed as an individual taking its age, health issues and performance demands into consideration. Dr. Thunes can be reached at
