Vitamin C (Ascorbic acid) has many beneficial functions in the human body. It is important to note that humans are one of the few species not capable of manufacturing vitamin C internally, and thus, are reliant on food sources of vitamin C for survival. This can lead to body levels inadequate for cellular protection. The following is a list of the main functions Vitamin C has in the human body:
  • This nutrient plays a major role in the manufacture and defense of our connective tissue, the elaborate matrix that holds the body together. It is a primary ingredient in collagen, a glue-like substance that binds cells together to form tissues. It strengthens and improves the health of joint tissue, tendons, ligaments, skin, hair, teeth, gums, blood vessels, intestinal lining, and all the sensory and glandular organs.
  • Vitamin C stimulates the immune system to fight off foreign invaders and tumor cells.
  • Vitamin C is vital for heart and circulatory health by facilitating fat metabolism, protecting vessels from free radical damage, and strengthening blood vessel walls.
  • Vitamin C maintains healthy bones, teeth, gums, tissues. It aids in wound healing.
  • Vitamin C combats inflammation and pain. It behaves like a “natural aspirin”.
  • At high doses only reached by intravenous injection, Vitamin C confers benefits for cancer patients. It has been shown to increase survival times in cancer patients, decrease the amount of radiation required, enhance the effect of chemotherapy, protect from the damage of radiation and chemotherapy, inhibit the growth of some cancers, and reverse some abnormal cell lines back to normal. It is known to enhance both quality and quantity of life. Up to 75 grams can be infused intravenously over a period of 2-3hours, 2-3 times weekly. (Intravenous Vitamin C is not a cancer cure).
  • Vitamin C is a potent neutralizer and detoxifier of toxins such as pesticides, alcohol, nicotine, aluminum, cadmium, nickel, lead, fluoride, PCB’s, etc. It not only neutralizes and removes these toxins from the body, but it protects our healthy cells from being damaged by these toxins.
  • Vitamin C is a potent anti-viral, anti-bacterial, and anti-parasitic agent. Oral vitamin C helps protect the body from developing infections, and high-dose intravenous vitamin C is an effective method of destroying and removing pathogenic microbes. Intravenous vitamin C has cured viral infections which can be debilitating and even life threatening such as swine flu, measles, mumps, viral encephalitis, chicken pox, shingles, herpes, viral pneumonia, colds, and flus. (Intravenous Vitamin C should be used adjunctively with conventional anti-microbial medication to augment and improve outcomes).
Vitamin C therapy both orally and intravenously has been used successfully by trained doctors for many years and is backed by volumes of research. It has proven itself to be safe and effective for several toxic, infective, and cancerous conditions. Talk to a trained Naturopathic Doctor to discover how this simple, inexpensive nutrient can benefit your health. This is not to say that this therapy should replace conventional medical advice. As always, collaborative therapy amongst all health care providers is the best overall approach.
To protect your health, it is important to supplement with pure ascorbic acid (vitamin C) buffered with sodium in the form or sodium-ascorbate powder in gram doses daily. Everyone has their own individual dose which is the “bowel tolerance” dose. Take the vitamin C in divided doses throughout the day, at least 3 times daily. Start with 500mg 3 times daily and if tolerated, increase to 1000mg 3 times daily. Continue increasing until regular bowel movements are achieved (at least once daily, soft but not diarrhea). If illness occurs, increase the dose incrementally because when sick, the body will use up more vitamin C to fight the illness. You should notice that your bowel tolerance dose increases when you are sick. Sodium ascorbate powder mixed in water or other liquids is the most economical and easy method of achieving optimal dosing. Adding liposomal vitamin C may be necessary in severe illness. Liposomal vitamin C is a fat soluble, very absorbable form of vitamin C that will not affect the bowel. Take a dose of 5 grams 3 times daily. This significantly increases intracellular levels of ascorbic acid which enhances the anti-microbial and anti-toxin effect. With severe infections, cancer, or inflammation, consider intravenous Vitamin C which will greatly increase the intracellular levels of this nutrient and act as a precursor to hydrogen peroxide which cancer cells and pathogens have little defense against. Normal cells contain the enzyme catalase which neutralizes the hydrogen peroxide and are therefore, unharmed by it. Pathogens and cancer cells accumulate excess iron as well as being deficient in catalase, making them particularly vulnerable to the effects of high dose vitamin C.
Vitamin C has an extremely good safety profile, and there is no toxicity associated at any dose. Electrolyte and blood glucose levels can be affected by intravenous infusion, therefore, these are monitored and adjusted for. Starting at lower doses and going slow helps to mitigate any issues. A rare enzyme deficiency (G-6PD) can lead to hemolysis, or red blood cell membrane breakage, with high dose IV-Vitamin C. This can be tested for prior to treatment. Also, end stage kidney disease is a contraindication for IV-Vitamin C and fluid overload conditions such as congestive heart failure are conditionally contraindicated. A doctor trained and experienced in IV therapy will ensure the safe use of this therapy.
For comprehensive scientific reviews and therapeutic uses of Vitamin C watch documentaries and lectures by the experts in the field on You tube or other podcast platforms such as: Dr. Thomas Levy: “Vitamin C and Antioxidant Therapy” (or read his book, “Vitamin C, Infectious Diseases, and Toxins”), and Dr. Suzanne Humphries, “Lecture on Vitamin C”. Also view lectures from the Riordan clinic which has collected decades of experience and conducts research around the use of Intravenous Vitamin C.
Andrew Saul is a prolific researcher of the biological effects of Vitamin C and has authored many books on the subject. He has reviewed the history of vitamin C which you can view on his website:
