Gonzalez Protocol
The Gonzalez Protocol is an individualized nutritional-enzyme cancer regimen developed by Nicholas J. Gonzalez, MD, building on William Donald Kelley’s enzyme therapy and John Beard’s trophoblast theory of cancer. It combines metabolic typing, individualized diets, large numbers of supplements, oral freeze-dried porcine pancreatic enzymes, and detoxification routines such as coffee enemas. The protocol is controversial.
