New Study Identifies the Optimal Dose of Intravenous Vitamin C for Future Anticancer Clinical Trials

The use of vitamin C to treat cancer patients first became popular in the 1970s as a result of the work of Nobel laureate Linus Pauling. However, studies conducted with orally dosed supplements did not demonstrate any clinical benefit in cancer patients, most likely due to the finding that the levels of orally administered vitamin C delivered to a patient’s bloodstream were considerably lower than the levels needed to kill cancer cells in either test tube or animal models. Recent studies in which vitamin C was administered intravenously (by IV) resulted in higher levels delivered to the patients’ bloodstream suggest that vitamin C may, in fact, promote anticancer activity.

What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.

Before Gerson: The Forgotten Medical History of Coffee Enemas

By Scott Wilson – In 1875, Dr. J.P. Thomas wrote about using coffee enemas for opium and belladonna poisoning. He referred to cases going back to 1858 and 1859 and described coffee enemas as one of the ordinary means of treatment. That word “ordinary” stopped me. He wasn’t describing an experiment. He was describing something physicians already knew.
