I rarely devote and entire blog to a single therapy. And when it comes to treating symptoms, I have never believed in magic bullets. But, if anything comes close, it’s good old vitamin C. 

Vitamin C (ascorbic acid) is a water-soluble vitamin that your body needs but does not produce on its own. It is instrumental in many of your body’s processes and can also help your body prevent and heal from infections.

Here is a brief history of vitamin C and it’s uses during the past century:

  • Ascorbic acid was discovered in 1930 by Albert Szent-Györgyi who showed that it enabled the body to efficiently use carbohydrates, fats, and protein. 
  • In 1935 Claus Washington Jungeblut, M.D. discovered that vitamin C was both prevention and a cure for polio, as well as hepatitis and herpes viruses. Between1935-1937 he showed that vitamin C could also neutralize other toxins, including tetanus, diphtheria, and staph.
  • In 1944, the Vitamin C Depletion Study was conducted to determine the minimal amount of vitamin C necessary to prevent scurvy. Food shortages caused by the war made foods rich in vitamin C hard to come by. During the study, the researchers depleted the subjects’ vitamin C levels, which created life-threatening emergencies.
  • In 1949 Fred R. Klenner, M.D. reported that he had successfully treated 60 polio patients by injecting large doses of vitamin C. All patients received 1,000-2,000 mg intravenous vitamin C every 2 to 4 hours depending on age for 24 hours, after which their fevers consistently went down. For the next 48 hours, the vitamin C injections were given every 6 hours. All patients were clinically well after 72 hours.
  • Klenner also reported that he successfully used high-dose vitamin C to treat diphtheria, herpes zoster, herpes simplex, chicken pox, influenza, measles, mumps, viral pneumonia, multiple sclerosis, tetanus, heavy metal toxicity, carbon monoxide poisoning, black widow spider and moccasin snake bites, pesticide burns, and much more.
  • In the 1950s, William J. McCormick proposed vitamin C as a candidate for the treatment of cancer.
  • In 1970 the chemist Linus Pauling reported that vitamin C was both preventive and therapeutic for the common cold and published a book entitled Vitamin C and The Common Cold, which became a best-seller. At that time, Pauling was considered the foremost authority on vitamin C. He even stated that vitamin C supplementation could decrease the risk of getting certain cancers by 75%.
  • In 1975 Hugh Riordan, M.D., a leading authority on nutrition and medicine, founded The Center for the Improvement of Human Functioning International Inc. (now the Riordan Clinic). He was most notably regarded for creating the Riordan Protocol for using mega doses of intravenous vitamin C (50 grams and higher) and reporting the positive effects vitamin C has on many chronic illnesses, including cancer and Epstein Barr virus. He authored more than 79 peer reviewed medical journal articles and papers and wrote 4 books. I had the pleasure of working with Dr Riordan when we both served on the board of the American Holistic Medical Association.
  • In 1984, Robert Cathcart, M.D. noted that a patient’s bowel tolerance to oral ascorbic acid increased considerably in proportion to the “toxicity” of their illness.
  • On January 26, 2020, Andrew Saul, Ph.D., named one of Psychology Today’s 7 natural health pioneers and Editor of Basic Health Publications’ popular Vitamin Cure book series, sends press release through his Orthomolecular Medicine News website stating that the coronavirus pandemic can be dramatically slowed or stopped with immediate widespread use of high doses of vitamin C.

12 Ways Vitamin C Supports Your Health

Vitamin C is essential to many of your body’s processes.

  1. Builds collagen. It is necessary for collagen synthesis which is important for healing bones, tendons, and ligaments after injury, as well as healing scar tissue and wounds.
  2. Keeps your teeth healthy. Vitamin C is also important for maintaining healthy teeth and gums.
  3. Reduces free radical damage. An antioxidant, vitamin C helps protect your cells against free radical damage, which means vitamin C is protective when it comes to the many chronic health problems caused by free radical damage, such as cardiovascular disease, inflammatory conditions, and even cancer.
  4. Lowers cholesterol and blood pressure. Vitamin C helps reduce LDL cholesterol and triglycerides and lowers high blood pressure.
  5. Supports endothelial cells. Vitamin C helps preventing endothelial dysfunction, the earliest sign of atherosclerosis.
  6. Helps your body absorb nutrients. Vitamin C promotes calcium and iron absorption and helps your body store iron.
  7. Supports healthy immune function. Vitamin C has been noted to play a major role in preventing and treating the common cold as well as other viral and bacterial infections by enhancing processes that kill unwanted microbes, supporting apoptosis, and enhancing differentiation and proliferation of B- and T-cells (possibly due to gene regulating effects).
  8. Keeps your gut microbiome healthy: High-dose vitamin C supplementation for 2 weeks showed microbiota-modulating effects in healthy individuals. The shifts of bacterial populations seen showed more beneficial bacteria with anti-inflammatory properties that are strongly associated with gut health.
  9. Improves metabolic syndrome. Higher vitamin C intake can halt a potentially deadly cycle of antioxidant disruption and health-related problems common in metabolic syndrome Dr. Saul also suggests that high-dose vitamin C may help curb appetite and food cravings.
  10. Relieves pain caused by gout. Gout is a painful arthritic condition caused by too much uric acid in the blood. When there is too much uric acid, it can crystallize and deposit in the joints. Higher intake of vitamin C is significantly associated with lower serum uric acid concentrations.
  11. May help you quit smoking. One study that Dr. Saul discusses showed that vitamin C spray helped smokers quit smoking without turning to food to replace their cravings and thus not gaining weight!
  12. Reduces vaccination side-effects. Vitamin C is a potent anti-toxin. In his paper Vitamin C Prevents Vaccination Side Effects; Increases Effectiveness board-certified cardiologist, attorney and author, Thomas E Levy, M.D., J.D.’s discusses the historical data and studies showing that vitamin C reduces (even eliminates) harmful side effects cause by toxins in vaccines, including mercury and thimerosal. In addition, he discusses the use of vitamin C to increase vaccine effectiveness. He also gives details regarding dosing of vitamin C for different ages and concludes that vitamin C should be part of every vaccination protocol.

My Vitamin “See” Experience 

A number of years ago I was going blind in my left eye from infectious crystalline keratopathy. I was being treated by the head of the corneal unit at the Massachusetts Eye Infirmary in Boston. But the antibiotics were not working, and my vision was getting worse with each passing day.

Fortunately, I had heard Dr. Cathcart speak at one of our medical meetings. And I remembered his recommendation to take enough vitamin C to saturate the tissues (which is when stools get loose). So, I did. I started taking handfuls of 1000mg ascorbic acid capsules.

This completely reversed the condition. The next morning, I woke up and my vision was clear. Nothing like good old vitamin SEE!

How Much Vitamin C Do You Need?

It can be difficult to find information regarding supplements and dosing these days. Nearly a century of reports and laboratory and clinical studies showing the successful use of high-dose vitamin C therapy is not just being ignored. Much of the medical literature regarding vitamin C and other natural therapies is being censored, contradicted, buried by search engines, and even expunge—especially information regarding the established use of vitamin C in preventing and treating respiratory infections.

Why is the clinical information showing the benefits of vitamin C and other nutrients in treating viral respiratory infections being ignored by the medical journals, the media, and the government during a pandemic? For one thing, the medical journals are funded by Big Pharma. And Big Pharma can’t make any money off vitamin C since it’s illegal to patent something that is found in nature.

So, here’s what I want you to know: When it comes to supplementing with vitamin C, you can’t go wrong. There is no harm in it. Vitamin C is not toxic and cannot build up in your body. It is excreted in your urine. And if you take too much you will have some diarrhea, so then you just take less. However, your body can adapt to higher levels of supplementation over a short period of time. So, once you reduce your intake of vitamin C to bowel tolerance, you can try increasing the amount slowly.

If you are healthy and looking to simply support your body with vitamin C, you can start by taking 100-200 mg/day. This can be enough to support your tissues and prevent infection. Taking more can enhance the benefits.

If you are treating an infection, you need to take a significantly higher amount—I’m talking 1gram or more. Again, you want to take it to bowel tolerance. But, remember that when you are sick, your bowel tolerance typically increases in proportion to the toxicity your body is experiencing.

When you are taking larger doses orally, it’s best to spread your doses throughout the day and have a buffer for your stomach. Water is fine if you are unable to eat something every time you take a dose.

There are so many more health benefits of vitamin C supplementation that I have not mentioned here. If you want to research using vitamin C for a specific concern, a good place to start is Dr. Saul’s website and the Orthomolecular Medicine News Service, for which he is the editor.

    Quick question. I heard two pod cast about making the 3grapefruit and 3 lemons to make your own HCQ. Do you boil the peels for 3 hours in water or do you boil the fruit in water for 3 hours? One pod cast used the fruit and one used the peels. I’m confused. Thanks in advance.

    Knocked it out if the park again! What an informative write up on vitamin C. Ironically my husband has increased his intake for protection against any bio weapons out there and we have noticed a marked improvement in his EBV. So much to research from this article. Thank you for all you do for humanity.

    That’s some very good information often omitted elsewhere. Thank you, Dr. Northrup!

    Re “Much of the medical literature regarding vitamin C and other natural therapies is being censored, contradicted, buried by search engines, and even expunged—especially information regarding the established use of vitamin C in preventing and treating respiratory infections.”

    Exactly right! A commentary sent in to the BMJ last year by a published author of the Orthomolecular Medicine News Service on the empirical value of vitamin C against Covid-19 got censored by the BMJ. However, you can read his cancelled commentary in this article of his at his website — “The 2 Married Pink Elephants In The Historical Room –The Holocaustal Covid-19 Coronavirus Madness: A Sociological Perspective & Historical Assessment Of The Covid “Phenomenon”” by Rolf Hefti.

    You can’t discredit the facts with censorship. That only exposes and discredits the censors.

    Are there natural ways to get vitamin c? Meaning, not synthetic supplements? I think you mentioned a drink you made out of grapefruit and lemon peels? Or whole food supplements? Thank you.
