Dr. Colleen Huber, NMD, continues her series on cancer biochemistry by explaining the critical roles of Vitamins B2 (riboflavin) and B3 (niacin) in preventing cancer. Referencing Nobel Prize winner Otto Warburg’s 1931 research, she states that the common cause of cancer is “irreversible injury of respiration” — meaning damage to the cell’s ability to produce energy through oxidative phosphorylation in the mitochondria.
