Vitamin C for Cancer: Miracle or Mirage?

Dr. Greger Takes on Vitamin C for Cancer in New DVD

Vitamin C is no stranger to controversy. It took 40 years between when citrus fruits were shown to cure scurvy in the 1700’s and their widespread application. Is it possible we’re in the midst of a similar 40 year lag between vitamin C discovery and implementation? Research in the mid-70’s by Linus Pauling (considered the greatest chemist of the 20th century) purported to show that terminal cancer patients treated with vitamin C lived four times longer, and sometimes even 20 times longer than those who hadn’t. Alternative medicine practitioners continue to treat thousands of cancer patients with vitamin C, but why isn’t it the standard of care in mainstream medicine? Has it been successfully debunked or is it a Big Pharma conspiracy to suppress the truth? Find out what the science shows in my three-part video series coming soon to

  • Intravenous Vitamin C for Terminal Cancer Patients
  • Vitamin C Supplements for Terminal Cancer Patients
  • The Role of Vitamin C in the Treatment of Terminal Cancer

If you want to watch all three videos now, though, they are available as a video download as part of my new Latest in Clinical Nutrition volume 28 (all proceeds go to charity). It can also be ordered as a physical DVD. The vitamin C videos are all scheduled to go up on next year, but you can download and watch them right now.

Other topics I take on in this volume include preserving immunity in athletes, how to change your microbiome, the French paradox, the use of fennel seeds and ginger for menstrual cramps. The one that most changed my own family’s diet was Lead Contamination of Tea, in which I do a breakdown of the risks and benefits for green, white, black, and oolong tea for children, pregnant women, and adults in general.

The current batch of videos from volume 27 on just ran out, so starting next month and running until February, I’ll be rolling out the videos from this new DVD, volume 28. The DVDs give folks the opportunity to sneak-preview videos months ahead of time, watch them all straight through, and share them as gifts, but there is nothing on the DVDs that won’t eventually end up free online at If you’d like the works–50+ hours of video–you can get the complete DVD collection.

  1. I’ve watched so many videos now that I always think I’ll be bored by the next volume. Nope. Once again I am sucked in and devouring the information. So, so interesting!

      1. :-) I go back and forth. I take the information in much better when I watch one video each morning. And I enjoy the fun of getting the next installment in the mornings. But since I get the volumes mailed to my house, sometimes I can’t wait. (tsk, tsk on me)

  2. My daughter is doing a course in Podiatry, and her nutrition lecturer stated that only 25mg of Vit C can be absorbed at any time; the rest leaves the system………….just wondering about this. On the other hand, I read about 10 years ago, that taking 13g of Vit C can actually eliminate cancer cells……

  3. i used to look forward to viewing the short, informative videos that i ot in my emails from dr. mcgregor; but now it seems that i have to pay for them. i can’t afford that, so i’ll be canceling my subscription to his emails i’m sad.

    1. The emails are free but if you want to buy the DVD to get the information sooner than you are able to do that. Otherwise stay tuned and enjoy the information in small videos like always.
