What is High Dosage Vitamin C ?

High-dose intravenous vitamin C (IVC) refers to the administration of vitamin C at significantly higher doses than those achievable through oral supplementation. In the context of cancer treatment, high-dose IVC has shown promising potential as a multi-targeting agent. Clinical trials have demonstrated its safety and suggested its efficacy in eradicating tumor cells. High-dose IVC is believed to exert its effects through various mechanisms, including pro-oxidative cytotoxicity, modulation of epigenetic regulation, immune modulation, and synergistic action with standard therapies. However, further research and clinical studies are needed to establish its clinical benefits conclusively.

What is Vitamin C?

Vitamin C is the most important water-soluble vitamin in the human body, because it is a cofactor for various enzymes, collagen, cholesterol metabolism, and synthesis of neurotransmitters in the body. Vitamin C, also known as Ascorbic Acid, also plays an important role in the function of immune cells.

Most mammals can synthesize vitamin C from their bodies on their own, but humans cannot make it by themselves due to lack of such genes. They must get enough vitamin C from other sources (such as food/nutrition supplements). Due to the instability of vitamin C in food, storage, high temperature or over-cooking will destroy many vitamin C. Eating natural foods alone may not be able to meet daily needs, so some people choose to take vitamin C-rich nutrition supplements, or pursue high dosage vitamin c therapy.

Limitations in Oral Intake of Vitamin C

It should be noted that the human body has a very strict regulatory mechanism for the absorption of vitamin C. Therefore, despite the high oral dose of vitamin C, the concentration of vitamin C in the blood is still maintained at tens of micromoles (μmol/L), making it unable to achieve optimal results. In addition, orally intake high-dose vitamin C may cause stomach irritation, nausea, vomiting, abdominal pain and diarrhea and other gastrointestinal symptoms.

High dosage vitamin c therapy drip, which is more common in Europe and the United States, a method that supplements vitamin C through intravenous injection, allowing vitamin C to be taken directly into the blood. This method helps elevate blood concentration of vitamin C to a level that is around 100+ times higher than having oral administration of vitamin C. In addition, this method can bypass the digestive system and avoid gastrointestinal irritation, and there are no obvious side effects. Therefore, some people choose to take high dosage vitamin C through IV drip.

Background of High-Dosage Vitamin C Therapy (IV Vitamin C)

As early as half a century ago, vitamin C has been used to prevent common colds and scurvy (Scurvy). Dr. Linus Carl Pauling, an American chemist who won the Nobel Prize twice, discovered that high dosage vitamin c therapy has a supportive effect on the overall cancer treatment plan. He and his team discovered that not only IV Vitamin C drip has the opportunity to enhance the immunity of cancer patients and promote the health of patients, but also may help on their life expectancy. Since then, more laboratory and clinical studies have discovered that applying high dosage vitamin C in cancer treatments has the potential to reduce the division of a variety of cancer cells, reduce cancer recurrence and improve the quality of life of patients (More studies are needed to verify such claims).

Therefore, high dosage vitamin c therapy, in Hong Kong and abroad, has widely been used in integrative therapy.

High Dosage Vitamin C as Supportive Therapy

Vitamin C is an antioxidant nutrient that is beneficial to the body. It is originally an essential nutrient for the body to reduce toxins and defend against infections. In addition to the fact that IV Vitamin C Drip can help increase the level of vitamin C in the blood, studies have also discovered that having a corresponding dose of IV Vitamin C has a supportive effect on radiotherapy or chemotherapy.

High dosage vitamin C in cancer treatment, has the potential to (1) reduce the side effect in traditional treatment (including nausea, loss of appetite, fatigue, depression, insomnia, dizziness, low immunity, weakness, etc.), and (2) support cancer patients for a better life quality.

Studies' viewpoints on High-Dosage Vitamin C

Different concentrations level of vitamin C have different functions in the human body. If the concentration of vitamin C in the body reaches 0.1mM, vitamin C , it could become an effective antioxidant, a molecule that can effectively slow down or prevent oxidation. At high concentrations of vitamin C, hydrogen peroxide (a type of reactive oxygen species) is produced during the breakdown of vitamin C, which can damage tissue and DNA. Normal cells have multiple pathways to remove hydrogen peroxide, keeping it low level to avoid injury. Compared with normal cells, the ability of cancer cells to remove hydrogen peroxide is relatively weak, so hydrogen peroxide may be able to destroy tumor cell tissue.

Studies have shown that tumor tissue has abnormally high levels of redox-active iron molecules (a byproduct of abnormal mitochondrial metabolism) that react with vitamin C to generate hydrogen peroxide and free radicals derived from hydrogen peroxide. These free radicals are thought to selectively cause DNA damage in cancer cells, potentially causing cancer cell death and increasing the sensitivity of cancer cells to radiation and chemotherapy.

Tumor angiogenesis is critical for tumor growth and metastasis, as it provides a nutrient supply and waste removal system. Studies have shown that high doses of vitamin C can help the synthesis of collagen, thereby strengthening the structural layer between cells, and have the opportunity to prevent cancer cells from penetrating the structural layer, thereby inhibiting the formation of new blood vessel tubules, preventing tumor growth and reducing spread. .

A study examined the clinical utility of intravenous vitamin C in terms of quality of life, conducted a prospective observational study of changes in quality of life caused by intravenous vitamin C, and evaluated its safety in cancer patients. The results showed that after 4 weeks of intravenous vitamin C treatment, the collected [Global Health Status Score] and [Functional Scale Score] showed significant improvement; in addition, subjective symptom scores, especially fatigue and insomnia scores were significantly improved . Based on these results, the study suggests that intravenous vitamin C can safely improve the quality of life of cancer patients.

A study published in Japan in 2012 showed that vitamin C drips can help improve or maintain the quality of life of cancer patients. Cancer patients who received intravenous vitamin C for 2 weeks experienced a significant reduction in the severity of some symptoms, including fatigue, insomnia, and constipation. After 4 weeks of treatment, pain began to significantly ease, and overall quality of life scores also improved significantly.

Who Shall Consider to consult a doctor for high dosage Vitamin C Therapy (IV VITAMIN C)

The following types of people may consider consulting a doctor for more information with regards to High dosage Vitamin c therapy, or for cancer treatment support:

  • People with Tumor 
  • Cancer survivor
  • Patients with chronic diseases and immune system diseases
  • Patient Arthritis

Clinical Safety of High Dosage Vitamin C
(IV Vitamin C)

The following people shall not consider having high-dosage vitamin C therapy in HK:

  • Patients with glucose-hexa-phosphate dehydrogenase (G6PD) deficiency
  • Patients with renal failure requiring artificial dialysis
  • People who are malnourished
  • People with symptoms of dehydration

The following side effects may occur:

  • Irritating pain at the area of injection
    There may be irritating pain at the site where the drip is injected (Decreasing the drip rate can relieve symptoms.
  • Dry mouth
    There is a chance of a diuretic bodily response to IV injections, you should drink plenty of fluids during or after your IV session.
  • Possibility of causing hypoglycemia
    At the chemical level, vitamin C has a very similar structure to glucose, and when the infusion is in progress, the body secretes insulin, causing blood sugar to drop and hypoglycemia to occur (although this is very rare). So try to avoid Take the infusion after a meal when the stomach is full.

Notes:

  • High dosage vitamin c therapy – be cautious of osmotic pressure, drip rate, synergistic nutrients, dietary coordination, and possible discomfort during the injection
  • Carefully monitor the dosage of Vitamin C
  • Generally speaking, some people may experience discomfort during the process of high-dosage vitamin c therapy in Hong Kong, mainly due to dosage level, such as headache, stomach cramps, dizziness, nausea, feeling thirsty, etc.

    Patient Testimonials

    Ms. Huang, 83 years old, stage 4 lung cancer

    Condition before consultation:

    She had undergone chemotherapy and targeted therapy. When she first visited the doctor, she was too weak to walk and unable to speak due to breathlessness. She also experienced severe side effects from chemotherapy and targeted therapy, including severe skin eczema, loss of appetite, and chronic diarrhea.

    Medical treatment status—2023 to present

    Since receiving treatment at BMS Clinic starting in 2023, her cancer markers have remained stable and within the normal range. She is now able to eat normally and walk on her own.

    She stated:

    “The biggest change in my body is that I feel energetic and strong. This is the best I have felt throughout my cancer treatment journey—sometimes, I even forget that I have cancer.”

    Ms. Zhang, 82 years old, bladder cancer, lung cancer metastasis

    Medical treatment status—2022 to present

    In 2022, she visited BMS Clinic accompanied by her daughter. 

    She had undergone partial bladder resection, but due to her lung condition, she was not suitable for radiotherapy or intravenous chemotherapy. Over time, her condition gradually improved. She undergoes an annual cystoscopy, and her cancer status has remained stable. 

    She is now able to maintain the best possible quality of life—she can walk, eat, and sleep well.

    Both she and her family expressed:

    “We are very satisfied with her current quality of life and overall health condition.”

    Mr. Chen, 80 years old, terminal liver cancer

    Medical treatment status—2018 to 2023

    diagnosed with terminal-stage liver cancer in 2018. 

    The doctor recommended palliative care. His son accompanied him to seek medical consultation. After undergoing a series of intravenous nutritional therapies, his cancer markers remained at normal levels during follow-up visits, despite imaging scans still showing late-stage cancer. He continued nutritional therapy for six years, from 2018 to 2023. 

    In 2023, he was hospitalized due to pneumonia and passed away while in isolation. 

    During his treatment period, he stated:

    “I could walk, eat, and sleep well. I felt very satisfied.”

    Ms. Chen, 50 years old, breast cancer

    Medical treatment status

    She was very resistant to chemotherapy and radiotherapy. After a series of nutritional drips and immune-adjuvant therapies at the clinic, combined with RGCC drugs and nutritional sensitivity tests, she successfully found targeted drugs for treatment and successfully shrunk her breast cancer. The breast tumor originally grew to 5-8cm in diameter and had been oozing a lot of pus, but now it has been successfully shrunk and her skin has returned to normal without the need for surgery.

    Self-report

    “Don’t underestimate nutritional drips and immune-assisted treatments, and think you made the right choice”

    Ms. Mo, 42 years old, breast cancer

    Medical treatment status

    I was very reluctant to have surgery because I would have to have a complete mastectomy. I wanted to seek nutritional drips and immune-assisted therapy to shrink the tumor before considering surgery. It was shown that with a series of therapies, the tumor was successfully shrunk by 10% and is no longer growing.”

    Self-report

    “I want to continue with the IV drip and then consider other treatment options, because the tumor is shrinking steadily.”

    Miss Zheng, 40 years old, brain tumor

    Medical treatment status

    After the brain tumor surgery, I was always prone to dizziness, headache, weakness, low iron and low platelets. After a series of nutritional drip treatments, I was finally able to exercise normally and return to a normal life. Now I travel everywhere and come to the clinic for drips every 2-3 months.

    Self-report

    “I have always paid attention to nutritional therapy, but I didn’t expect that my gastrointestinal absorption was very slow and I didn’t know whether it was absorbed into the body. Now I am receiving intravenous drips, which are very effective and my body functions have recovered quickly.”

    Ms. Jiang, 72 years old, breast cancer

    Medical treatment status

    After breast cancer surgery, I did an RGCC blood circulating tumor cell test, and the CTC value was 7.3 cells/ml. I was worried about the risk of metastasis and recurrence, but my family and I did not want chemotherapy and radiotherapy. We wanted to cooperate with nutritional drips and the RGCC nutritional sensitivity test results to cooperate with high-sensitivity nutritional vegetarian therapy. After half a year of hard work, the CTC value was successfully reduced to 2.7ls/ml. My family said they were very happy and would continue to cooperate with nutritional supplements and nutritional infusions. Now they are scheduled to come to the clinic every two weeks or every week for nutritional drips.

    Self-report

    “I am very satisfied with my current condition. If I had chosen chemotherapy, I might not have been able to survive the entire chemotherapy and maintain my current quality of life. At least now I can do whatever I want without my family’s care.”

    Highlight on High Dosage Vitamin C:

  • Study of high-dosage vitamin C and cancer cells: Vitamin C is easily broken down, and hydrogen peroxide will be produced in the body in the process –   a type of reactive oxygen that can damage tissue and DNA. The study also showed that tumor cells are much less capable of clearing the hydrogen peroxide than normal cells. Therefore, using high doses of vitamin C is expected to generate a substantial amount of H2O2 (hydrogen peroxide) in cells, and cancer cells are not capable of excreting H2O2 (hydrogen peroxide), resulting in apoptosis of cancer cells.
  • Some human trials have shown that high doses of vitamin C may help ease chemotherapy side effects including (fatigue/nausea/quality of life/appetite)
  • Whether oral consumption of vitamin C can achieve the effect of causing apoptosis of cancer cells? Studies have shown that vitamin C must be injected intravenously in order to escalate the concentration of vitamin C in blood to reach 20mM.
  • Some experiments have found that high dosages of vitamin C has antioxidant effects and reduce the division of prostate, pancreas, liver, large intestine, mesothelial, and neuroblastoma cancer cell lines in Petri dishes in the laboratory.
  • Some animal experiments have found that high dosage of vitamin C can slow down the growth of tumor cells.
  • Two human studies have found that high doses of vitamin C (intravenous) may help patients with end-stage cancer in their quality of life and have the potential to reduce side effects (such as nausea, vomiting, etc.) of cancer treatment

    ASk US Anything about IVC

    The cost of high-dose vitamin C varies across different countries. In Hong Kong, the price ranges from HK$2,500 to HK$3,500 per session (varies by dosage), typically charged in a treatment course of 10-session.

    Due to the fact that the administration of high-dose vitamin C injections is a procedure that requires supervision by healthcare professionals, it must be conducted by qualified medical personnel to ensure the accuracy of infusion and the safety of the process.

    High-dose vitamin C Therapy cannot replace traditional/conventional mainstream treatments such as chemotherapy, radiation therapy, cellular therapy, or immunotherapy. It is important to consult with your doctor to plan an appropriate adjunctive treatment plan and to coordinate with the treatment plan of mainstream conventional medicine.

    The recommended dosage, duration, and frequency of treatment may vary depending on the individual’s condition and tolerance.

    Typically, a single infusion of high-dose vitamin C ranges from 300ml to 500ml, and the administration time is approximately 60 to 90 minutes.

    After diagnosis, the doctor will advise on the appropriate dosage, duration, and frequency of treatment.

    High-dose vitamin C therapy can enhance immune function, and there are studies suggesting a potential reduction in the risk of developing cancer or its spread (further research is needed). It may also contribute to improving the effectiveness of chemotherapy and radiation therapy (further research is needed). Cancer patients, individuals in recovery, those with chronic diseases, or immune system disorders can consult with healthcare professionals and doctors to learn more about this treatment method.
