The Power of Vitamin C Therapy in Pets
Twenty-five years ago, I published an article about Vitamin C as a natural means of cancer therapy. At that time, there were several studies investigating how Vitamin C, given in high doses and intravenously, had positive outcomes in various therapies, including cancers. High-dose Vitamin C has been studied in cancer patients since the 1970’s. Nobel laureate Linus Pauling published a book in 1970 claiming high-dose Vitamin C could prevent the common cold, the flu, and cancer. Studies at that time showed that much higher blood levels are reached when Vitamin C is given intravenously than when taken by mouth. Some of those studies showed that in animal models, high-dose intravenous Vitamin C blocked tumor growth in pancreatic, liver, prostate, sarcoma, ovarian, and malignant melanoma.
Current statistics tell us that 50% of dogs and 30% of cats over 10 years old get cancer. This personally bothers me. Over the years, it has become more difficult to get injectable Vitamin C (Ascorbate). Recently, it has become available to me. As such, I am officially announcing that High- Dose Vitamin C infusions will be available at Animal Wellness Center in Chadds Ford, Pa. 610-558-1616. This will allow me to, once again, be able to provide comprehensive treatment for cancer and other diseases.
My most recent search of PubMed revealed over 82,000 publications on Vitamin C. Over 7,800 publications were on Cancer and Vitamin C. This is encouraging, but a lot more research is necessary to get this kind of treatment into the mainstream. Evidence is growing that indicates that Vitamin C has the potential to be a potent anti-cancer agent when administered intravenously and in high doses. It is very important to understand that this treatment must occur intravenously. Giving your pet Vitamin C tablets by mouth does not affect your pet the way intravenous infusion does. Too much Vitamin C by mouth will cause severe gastrointestinal upsets, vomiting, and diarrhea.
Many mechanisms have been proposed, particularly pharmacokinetic research, as to exactly how Vitamin C works. This is an extraordinary undertaking and will take time and a lot of money. Reports in the literature suggest that angiogenesis, which is the formation of new blood vessels towards and into the tumor, is inhibited by IVC (intravenous Vitamin C). Many studies support the idea that High-dose Vitamin C infusion appears to boost production of hydrogen peroxide in the bloodstream, which kills cancer cells, leaving perfectly healthy cells alone (Mussa, Ali et al, 2022). Other publications show that IVC in high doses exhibits anti-tumor effects. This includes “immune modulation”, “pro-oxidative cytotoxicity”, and “anti-cancer epigenetic regulation” Zhao, H. et al, 2025). A study was done in mice (Zhao, Xixi et al, 2024) that showed that high-dose vitamin C suppressed tumor growth and enhanced T-cell infiltration and function in the tumor microenvironment. Studies also suggest that High-dose Vitamin C infusions can act synergistically with numerous chemotherapy therapies and reduce
the toxic side effects such as loss of appetite, fatigue, depression, sleep disorders, dizziness, and diarrhea.
Inflammation is the hallmark of disease. It is involved in tumor development and metastasis. We can now measure markers of inflammation in the body. Intravenous high-dose Vitamin C will significantly reduce these markers of inflammation. This characteristic of Vitamin C allows it to be a treatment for multiple conditions. Vitamin C is an immune system booster with anti-bacterial, anti-viral, and antihistamine properties.
Vitamin C is a strong water-soluble vitamin that is involved in the body’s utilization of collagen, bones, blood vessels, muscle, normal growth and development, adrenal function, hormone production, cholesterol metabolism, bile production, detoxification, iron absorption, protecting cells from free radical damage, and immune function. There is no doubt that Vitamin C is essential to life itself; therefore, it can affect a multitude of issues within your pet’s body.
I am proud to be able to once again add this to my armamentarium!
