Recently, Vitamin C has been forced into the backseat as other antioxidants have stood in the limelight.  Vitamin C is the grandfather of antioxidants and it has clear health benefits.(1)

Dr. Ronald Hunninghake is well known for being an expert on this vitamin.  He joined Dr. Hugh Riordan over twenty years ago and conducted research on I.V. administration of vitamin C for cancer patients.   Though his clinic is the leading expert on vitamin C therapy for cancer, that hasn’t stopped others from completing similar research.(1)
New study builds on prior work of Dr. Hunninghake and shows that vitamin C kills colorectal cancer cells!

A recent study found that vitamin C could help fight colorectal cancer.  The equivalency of vitamin C found in 300 oranges was found to kill colorectal cancer cells.  Colorectal cancer is the third most common cancer in the United States.  Approximately 50 percent of cases are more aggressive and do not respond to conventional therapies.(2)

The new study from Weill Cornell Medicine in New York discovered that in these cases, that high-dose vitamin C caused oxidation in the cancer cells and impaired the growth of the tumors.(2)

Vitamin C is generally thought to improve health because of its antioxidant effect, which prevents or delays some types of cell damage.(2)

The studies findings may also be helpful in treatment of renal cell carcinoma, bladder cancer and pancreatic cancer.  The authors of the study report that that dosage would most likely need to be through I.V. as oral doses are not absorbed efficiently enough through the intestine.(2)
High doses of vitamin C do not absorb efficiently through the intestine and should be administered intravenously

Dr. Hunninghake recommends an average person take 1 gram of vitamin C twice per day.  If you are suffering from chronic infections or fatigue you can gradually increase the does to a bowel tolerance dose.  For most patient, oral dosages are fine but if you are fighting a serious illness, Dr. Hunninghake recommends I.V. vitamin C therapy.(1)

If you are seeking to increase vitamin C consumption through food, consider increasing your fruit and vegetable intake.  Many eat oranges for their vitamin C content, but red and yellow bell peppers have the highest vitamin C coming in at 306 percent of daily value.  Other fruits and vegetables are guavas, dark leafy greens, kiwi, broccoli, berries, tomatoes, peas, papaya, and of course oranges.(3)

As winter approaches, don’t forget about vitamin C!  Start eating more fruits and vegetables and consider adding a high quality supplement.  If you are battling cancer or another chronic disease, consider intravenous vitamin C therapy!
