Professor Marco Ruggiero MD


PhD in Molecular Biology and is a certified Medical Doctor specialised in Clinical Radiology. 

Has worked at Burroughs Wellcome Co North Carolina, USA publishing a seminal paper with Nobel Laureate Sir John Vane and, subsequently, at the National Cancer Institute of the NIH in Bethesda, USA.

Has published more than 150 peer-reviewed scientific papers. For 20 years he has worked on the vitamin D axis, a metabolic pathway that includes GcMAF. In the past 3 years he has published studies on the immunotherapeutic effects of GcMAF in a variety of conditions.


GcMAF: the guardian of our health. From molecular modelling to clinical practice.


GcMAF has been the object of intense research in the past 20 years for its role in the immunotherapy of cancer, autoimmune diseases, and HIV infection. In the past few years solid scientific evidence accumulated demonstrating that its role goes well beyond its capability of activating macrophages and rebuilding the immune system. The most recent evidences at the cellular and molecular levels indicate that it is indispensable for the healthy function of vital systems, a concept that had been empirically observed by many clinicians treating their patients with GcMAF for the most diverse pathologies. In an analogy with p53, “the guardian of the genome”, a protein that interacts with GcMAF, this latter molecule can aptly be defined “the guardian of our health”.
