Loomis Enzymes® as we know it today evolved from Dr. Howard F. Loomis Jr.'s goals of providing high quality products and great value to healthcare practitioners and their patients. So much of our history is tied to the story of Dr. Loomis, and so much of our future will be rooted in his principles.

The Road to Loomis Enzymes®

Dr. Loomis graduated from Logan Chiropractic College in 1967 and opened his first clinic soon after. A 2nd generation Chiropractor, his father had used pancreatic enzymes and betaine HCl to improve digestion. He strongly believed digestion was the place to begin healing or to maintain health-not to cure disease.

Using traditional digestive supplements like his father, Dr. Loomis worked for 12 years to make nutrition work as a science by correlating laboratory results with physical examination findings. In 1980 he was introduced to the work of Dr. Edward Howell and his food enzyme concept, convincing Dr. Loomis he had finally found the missing link for providing consistent results in clinical nutrition.

Changing the Face of Clinical Nutrition

By combining Dr. Howell's theoretical work with his own work correlating laboratory results with physical examination findings, Dr. Loomis began to use individual enzyme supplements to establish exactly how each enzyme influenced the body. After 5 years of extensive trial and error, clinical study, and reviewing laboratory results the first products were ready to go to market.

He spent the next 8 years lecturing on the clinical applications of plant enzymes, continuing his private practice, clinical investigations, and raising his family.

In 1993 he sold his private practice in order to start his own supplement company, establishing Enzyme Formulations in 1995. He spent the next 23 years building his company and perfecting his products while continuing to lecture and find the time to author four published books. The Chiro-Zyme®, Thera-Zyme® and Enzyme Solutions® products he created during this time are the foundation of the current Loomis Enzymes® products.

Dr. Loomis' Legacy

In 2018 Dr. Loomis chose to focus on lecturing and writing and provided his children with the opportunity to continue his goal of providing high quality products and great value to healthcare practitioners and their patients.

Working by his side for the last 23 years and under his guidance, his son Howard and daughter Christina have handled the day to day tasks of running the company for the last decade. In 2019 Loomis Enzymes® was formed to continue his legacy by providing the quality products, made to his exacting standards, which our customers rely on.
