High Dose Vitamin C Formula

Energize | Reduce Fatigue | Support Health

Adjunctive cancer treatment with high dose vitamin C by intravenous delivery is focused on improving the side effects commonly seen with cancer treatments. Studies that evaluated for the use of high dose vitamin c to patients undergoing concurrent cancer therapies have found that the IV high dose vitamin c reduces nausea and fatigue, and helps to improve energy [1-5]. 

 

Intravenous Vitamin C is more effective at raising the concentration of the vitamin in the blood than taking an oral supplement. IV Vitamin C can achieve concentrations 50x or more higher when compared to oral supplementation. The high concentration of vitamin c is believed to be beneficial for cancer therapies as it increases the production of hydrogen peroxide in the extracellular compartment, and this can cause cell death in cancer cells, while normal cells seem to show little sensitivity to the hydrogen peroxide. It also has a pro-oxidant effect which creates free radicals (contrary to the usual antioxidant effect of low dose vitamin c) [6-8].

 

High dose vitamin C may help to slow cancer progression when used adjunctively to conventional cancer treatments. There are observations in studies that the disease process of cancer depletes the body of Vitamin C, and why its administration may be crucial during treatment [9].

High dose vitamin c is never used as a monotherapy (on its own), but only adjunctive to conventional care. To date, there are limited high-quality clinical trials and the utility of high-dose vitamin c remains uncertain. Although, the limited trials done thus far demonstrate benefits and good tolerability [9].

 

Prior to starting any therapies it is important to discuss with benefits and risks with your oncologist and a naturopathic doctor.
