What if a remedy existed that was powerful, supremely versatile and had unparalleled safety? What if that remedy was not only highly effective as an antibiotic but just as effective as an antiviral? What if, in addition, it removed toxicity and improved well-being? And what if it had no side effects? It would be the Holy Grail of medical treatments.

But such a remedy does exist and it costs next to nothing.

That remedy is megadose Vitamin C.

            I understand that this may seem an extraordinary claim and I would not be surprised if you were more than a little sceptical but stay with me and let me give you the evidence.


           An astonishing study was published in November 2016 comparing sepsis patients in intensive care units given intravenous vitamin C, hydrocortisone and thiamine (vitamin B1) and those given standard treatment. In the first group 8.5% died whilst in the second group 40% died (a 500% improvement in mortality)1. However Dr Marik went on to treat a further 150 patients with the Vitamin C protocol and the mortality in this group was only 1% (expected mortality 30-50%). Two other interesting facts emerged. Firstly all these ill patients had very low levels of vitamin C and secondly the dose given intravenously was quite small (1.5 grams 6 hourly).

           A randomised, double-blind trial study done 2 years later at seven different intensive care units (ICU) in the USA showed a striking reduction in all-cause mortality (by approximately a third) and a significant increase in ICU and hospital-free days after using a Vitamin C infusion even though Vitamin C was only used for a miserly 4 days and at a relatively low dose 3- 5 grams daily2.

         Another trial of looked at 471 patients ventilated for over 10 hours. Giving Vitamin C (again at a fairly low dose of 1 to 6 grams daily) reduced the time on a ventilator by 25%3. What was striking about the study was that Vitamin C helped the most severely affected patients the most, something almost unknown with other forms of medication3.

         The major cause of fatality in Covid 19 is Acute Respiratory Distress Syndrome (ARDS). A critical question is what difference does Vitamin C make in ARDS? A case study in 2017 gives us the answer: “infusing high dose Vitamin C into this patient with virus-induced ARDS was associated with rapid resolution of lung injury. Intravenous vitamin C as a treatment for ARDS may open a new era of therapy for ARDS4.”

      Intravenous Vitamin C has been successfully used in China for Covid 19 patients with no deaths in those given Vitamin C.

Vitamin C was also used to save a man dying from swine flu when nothing else had worked (see Youtube: The Swine flu Miracle).

       But these results should not surprise us. Dr Frederick Klenner successfully treated 41 cases of viral pneumonia in the 1940s using doses of 20 to 120 grams daily5 (much higher than the above studies). Dr Klenner used megadose Vitamin C to successfully treat numerous infections including polio, tetanus, influenza, viral pneumonia and viral hepatitis.



        Vitamin C was used in the 1930s to effectively inactivate diphtheria and tetanus toxins and used for snake bites, burns and mushroom poisoning. In an extraordinary study of 31 patients with tetanus in Bangladesh in the 1980s one group was given standard treatment (anti-tetanus serum, antibiotics) whilst another group received this plus vitamin C. In the conventionally treated group 75% died. None in the Vitamin C group died.6

         Animal studies in 1964 by Mokranjac and Petrovic found that Vitamin C prevented death from what would normally have been a lethal dose of mercury chloride.

            Another remarkable story about Vitamin C is that it protected emergency workers against the effects of radiation after the Fukushima earthquake (see previous blog on Chernobyl, Fukushima and a Remarkable nutrient). Those at Chernobyl didn’t receive it and the results were horrific. 

If Its this Good Why Have I Never Heard Of It?

              You might well ask.
    Dr Cathcart, an expert in the use of Vitamin C was frequently asked to give interviews for television. Not one single interview was aired.

             A lot of effort went into making sure this discovery was kept quiet. This continues today. But why? The answer is that this cheap, extraordinarily effective remedy is seen as a threat to the market for more expensive patented products.
           How many people with Covid 19 could have been saved if Vitamin C had been used? No one knows. But my guess is that over 50% of lives could have been saved.

How to Use Vitamin C

            To use Vitamin C as an antibiotic or an antiviral it must be used at high dosage. The body burns up huge amounts of Vitamin C during an infection so it needs to be saturated in it to begin recovery. This means it increasing it to bowel tolerance. This is the dose that produces mild diarrhoea. Then it can be reduced slightly. If it is given by mouth the dose will probably be between 10 and 20 grams daily during an infection. This needs to be spread out over the course of the day to keep levels high.

           Dr Klenner was very clear that the more serious the disease the higher the dose of vitamin C needed and the longer the treatment should be.

           Take the case of an 11 month old child with a severe recurrent infection, unresponsive to antibiotics, described by Dr Campbell. Only when the baby was given Vitamin C every 15 minutes to a total of 20 grams throughout the day was bowel tolerance reached and he finally recovered and slept through the night for the first time in a week.

         The moral of the story is to get the full benefit from Vitamin C you have to keep giving it until there is a change in the bowels. There is only one problem with Vitamin C: that is not giving enough.
