Massive evidence has been compiled over the past 80 years (!) of the significance of this vitamin in high doses. An excellent and detailed historical accounting is in the new book by Dr. Thomas Levy, M.D. “Vitamin C: Infections, Diseases, and Toxins”. From infections to cancer, the evidence of its powerful influence is simply astonishing when administered IV and in doses far too high for oral intake. Add on to that the fact that it is entirely non-toxic even in very large doses. Our “Meyers Cocktail” contains 5,000 mg and our Immune booster has 25,000 mg of non-corn ascorbic acid.
