Gonzalez Therapy
Also Known As:
Enzyme Therapy

The Gonzalez regimen is based on the role of enzymes in the body and consists of a special diet based around the patient’s metabolic type, supplementation with nutrients and enzymes, along with detoxification. These are all given to enhance the liver’s function which aids in the process of excretion and metabolic waste. It is believed that toxins from the environment and food build up in the tissues, preventing the body’s innate defences from working properly and allowing cancer to develop. Gonzalez regimen is based on the theory that pancreatic enzymes assist the body to eliminate toxins that can lead to cancer.


Each treatment protocol is individualised for each patient. Regimen for this therapy is: Diet, supplements, pancreatic enzymes and detoxification routines. Up to 130-175 capsules can be taken per day including nutrients as well as enzymes. Patients receiving chemotherapy and/or radiation are advised not to do this programme during this time.


In 1906, Scottish embryologist Dr John Beard first proposed that pancreatic enzymes, in addition to their digestive function, represent the body’s main anti-cancer defence mechanism. After his death in 1923 his work was largely forgotten. In 1981, Dr Gonzalez, as part of his studies, researched the use of oral pancreatic proteolytic enzyme therapy. During this time he also met Dr. William Donald Kelley who had, for 20 years, been giving people with cancer with a complicated nutritional therapy based on Beard’s enzyme therapy.
