Intravenous Vitamin C vs Oral/Liposomal Vitamin C
There is some evidence that high dose vitamin C effectively weakens or outright destroys cancer. However, the evidence is mixed. Years ago the Mayo clinic conducted a well controlled study and concluded that vitamin C is worthless in the fight against cancer. However, they primarily used oral forms, and recently wrote: “vitamin C given through a vein (intravenously) has been found to have different effects than vitamin C taken in pill form. This has prompted renewed interest in the use of vitamin C as a cancer treatment. There’s still no evidence that vitamin C alone can cure cancer, but researchers are studying whether it might boost the effectiveness of other cancer treatments, such as chemotherapy and radiation therapy.”
I started Intravenous vitamin C (IV-C) treatments shortly after my diagnosis. At lower serum levels vitamin C acts as an antioxidant and this does not kill cancer cells. However, one way to kill cancer cells is to expose them to pro-oxidants. In high serum levels vitamin C becomes a pro-oxidant. Many chemotherapy drugs act on the same principle. The majority of the IV-C cancer fighting action is due to the pro-oxidant effects (via reactive oxygen species or ROS). Although I think that IV-C treatments are effective they are expensive and inconvenient so I tried to find an alternative that would increase the serum levels of vitamin C up to the levels that I obtain with IV-C. I found a decent amount of research that led me to entertain the possibility that a combination of oral and liposomal vitamin C can increase serum levels considerably (albeit not as high as IV-C) and has the advantage of remaining in the body for a substantial period of time, as well as being more convenient and less expensive.
However the National Institute of Health (NIH) states that IV-C can increase serum levels up to 14,000 uMol/l and oral can only get you to about 220 uMol/l.
Rather than jump to any conclusions I attempted to test serum C levels myself so that I could compare both methods. I came up with 4 methods: 1) urine test strips – I attempted to use those for blood serum measurements – they didn’t work properly. 2) Iodine/starch measurements – more accurate but I needed high quantities of blood. 3) Lab serum C analysis – accurate but very expensive to conduct my tests. It is also very difficult to coordinate 30 minute or 1 hour lab test intervals. 4) Diabetes glucometer. I spoke to Dr. James Spurgeon about this and he said that vitamin C mimics glucose, uses the same pathways, and falsely raises the level of glucose seen by the meter.
So I proceeded forth with the glucose measurements.
To summarize the results, the increase in serum C using oral and lipsomal vitamin C and some synergists is negligible. I measured up to about 220 uMol/l (.22 mMol/l) and this is exactly what the NIH stated. Note that I’m not positive about the exact number since the resolution of the meter probably comes into play and blood glucose measurements are likely not as accurate as lab serum vitamin C measurements. Certainly MUCH less expensive – $60 for a glucose monitor that can be used for 100 tests vs $100 for a single lab test. Regardless, the serum C levels appear to be fairly low.
The increase from 50 grams of IV-C is considerable. I measured up to about 10,000 uMol/l (10 mMol/l) and the peak was quite likely more than that – agrees closely with the NIH. The serum levels apparently remained high for hours. Contrary what some of the literature suggests. So I am continuing the IV-C once per week and discontinuing oral and liposomal vitamin C protocols. I do, however, get much more than the RDA from my diet; which includes a fair amount of fruit and vegetables.
To take advantage of the pro-oxidant affects of vitamin C it is important to note that research has shown that you can kill most cancer cells in the laboratory with values between 0.5 to 3mMol/L.
Antioxidants counteract the pro-oxidant affect of IV-C so I discontinue use of supplemental antioxidants and molecular hydrogen (also an antioxidant) on the days that I do IV-C. I am currently following a “burst” method. I do IV-C 3-5 straight days during one week each month and then only once a week for the remainder of the month.
I encourage you to use a blood glucometer to do your own testing. They are inexpensive and simple to use. As of the time of this writing the Contour Next is one of the most accurate ones. If you’re like me you want to see things with your own eyes…
These are the results of my testing:

Here is another result. Some oral vitamin c, rose hips, bioflavanoids, 75G IV:

Selenium supposedly potentiates vitamin C. So soon I am going to add 10% of the RDA (recommended daily allowance) into the IV and see if it makes a difference.
I am also going to see if the peak is precisely when the IV is done (important to know the peak value because we need to get to a therapeutic dose). To this end I am going to measure glucose every minute after the IV is finished.
I’ve spoken with a couple of doctors about my measurement technique. Both doctors think that a glucometer test is more accurate than a lab test (C degrades in serum and the sample needs to be frozen – any delay after thawing or before it freezes affects the result).
