Gonzalez Protocol™ at a glance

The Gonzalez Protocol™ includes several approaches with the goal of altering cancer metabolism:1PDQ Integrative, Alternative, and Complementary Therapies Editorial Board. Gonzalez Regimen (PDQ™): Patient Version. 2015 Sep 4. In: PDQ Cancer Information Summaries [Internet]. Bethesda (MD): National Cancer Institute (US); 2002–. Viewed August 26, 2022. 

  • Freeze-dried pork pancreas rich in naturally occurring pancreatic enzymes and enzyme precursors as the main anticancer component of the protocol
  • A large number (more than 100 per day) of nutritional supplements
  • An individualized diet of mainly organic foods
  • Coffee enemas twice a day 

This protocol combines the work of Nicholas Gonzalez, MD; Linda Isaacs, MD; and William Kelley, DDS. While this protocol has some similarities to the theories and practice of Max Gerson, MD, it differs substantially in supplementation amounts and dietary recommendations.2PDQ Integrative, Alternative, and Complementary Therapies Editorial Board.

Very few published studies have investigated outcomes among people with cancer treated with the Gonzalez Protocol™. Small studies have shown promising effects on survival. A larger controlled trial found worse outcomes compared to chemotherapy, although published critiques of that study question whether the people purported to be following the Gonzalez Protocol™ were actually doing so.
