About this episode

Dr. Richard Z. Cheng discusses the efficacy of high-dose intravenous vitamin C in treating diseases and the skepticism surrounding its use.

Do the many clinical trials into high-dose vitamin C prove it can actually treat the common cold and cancer, rather than just boost the immune system? Why is there ongoing scepticism? Why are multifactorial chronic diseases so hard to study in clinical trials? What is the right dosage to get the best results from vitamin C?In this episode we have the often misunderstood topic of Vitamin C as an antioxidant to get clear on, particular the high-dose approach and particularly delivered intravenously. Despite a very clear consensus that Vitamin C is a great booster to immune function, research that shows that it helps fight the common cold or flu have been dismissed by doctors and medical researchers; as well as claims that higher doses can increase its efficacy. Other claims that Vitamin C can help fight cardio-vascular disease and even cancer have been with even greater scepticism. So what exactly can vitamin C do to assist our immune function to fight disease, and why is there so much confusion about the answer given the high quantity of clinical trials data?Fortunately today’s guest has exactly the right skill set and research knowledge to separate the science from the here-say…
