Black Veterinary History

Zalk Veterinary Medical Library highlights Black veterinarians and veterinary history from their collection and beyond.


Wendell O. Belfield Sr., DVM

1928 - 2018









Dr. Wendell O. Belfield was a veterinary doctor and pioneer in promoting wholesome foods for pets. He had a successful veterinary practice in San Jose, California, where he dedicated his professional life to improving orthomolecular therapies for small animals.

Dr. Belfield’s clinical knowledge served as the catalyst for enhanced nutritional products, successfully addressing ineffective conventional treatment protocols for many animal diseases. Through trial and error, he developed combinations of nutrients that are indicated for specific disease processes, and conducted research to establish the efficacy of his treatments.

Dr. Belfield's original formulas are still available at Orthomolecular Specialties (OMS).
