GcMAF is a naturally occurring protein found in all healthy humans. It is a replacement therapy for those who can not make their own GcMAF naturally – usually if their immune system is depleted It replaces the missing part of the immune system and when it is properly produced it is perfectly sterile and safe.

It is actually a replacement therapy for those who’s own immune system is depleted. GcMAF neutralizes the immune suppressing enzyme Nagalase and then binds with Vitamin D to activate, regulate and expand the macrophages to become cytotoxic to tumours, viruses, pathogens and bacteria.
