High Dose Vitamin C and Cancer Research

Can Intravenous High Dose Vitamin C Be an Effective Cancer Therapy Treatment?

From the time we’re young, we’re told to take vitamin C to fend off and fight illness. Today,high doses of vitamin C are used to address a variety of health conditions including certain cancers. The benefits of high-dose vitamin C on quality of life for cancer patients has long been argued, but emerging clinical evidence supports high-dose vitamin C given intravenously as part of a treatment plan to fight certain cancers.

There is significant evidence to support that vitamin C can improve immune function and support general health. Research has indicated that alongside radiation and chemotherapy methods, high-dose vitamin C can enhance treatment outcomes.

Using high doses of vitamin C to kill cancer cells began back in the 1970s, when it was discovered that some properties of vitamin C may make it toxic to cancer cells. Researchers are studying the effectiveness of high-dose vitamin C IV when used along with other cancer treatments like chemotherapy and radiation therapy.

Intravenous High Dose Vitamin C (IVC)

IVC is a commonly used therapy among naturopathic doctors and integrative oncology healthcare practitioners. Studies have shown a correlation between the frequency of high dose vitamin C treatments and tumor growth, with decreased PSA levels as IVC treatment frequency increased.

“While research is still ongoing, the existing evidence does suggest that IV Vitamin C can have a significant impact on patients, without any adverse side effects on health or wellbeing,” says Dr. Manfred Eggersdorfer Professor of Healthy Aging and Chair for Healthy Aging at the University Medical Center Groningen.

“Studies by Welsh (2014) and Yun et al. (2015) are just some examples of trials that have indicated an improvement in quality of life and physical, mental and emotional functions, as well as symptoms of fatigue, nausea, vomiting and pain in cancer patients, although it is widely recognized that therapy is needed over a longer period of time to maximize efficacy,” said Eggersdorfer.

Laboratory studies have shown that IVC along with other therapies can slow the growth and spread of prostate, pancreatic, liver, colon and other types of cancer cells. Studies also show IVC can improve quality of life for cancer patients.
