New study on Vitamin C and cancer indicates at least one powerful mechanism of action

There has long been controversy over Dr. Linus Pauling’s work indicating extremely safe high doses of intravenous vitamin C often killed cancer cells and saved lives.   Other researchers in follow up studies used oral vitamin C not intravenous.  When these different protocols failed to show the same effect, it was concluded Dr Pauling was wrong and indeed he was often branded a crack-pot.  We now know that blood levels from intravenous vit C reach 100-500 times those possible with oral use.  Leaving aside the puzzling question of why researchers didn’t duplicate the original protocol, this understanding opened the door for many integrative MD’s and oncologists to use Dr Pauling’s protocol to this day as one of their life saving tools.

A recent study by researchers at the University of Iowa using live cell arrays has identified at least one of the ways vit C can kill or weaken cancer cells. Oral vit C acts like an anti-oxidant, but When high dose vitamin C breaks down it releases H202; commonly known as hydrogen peroxide.  Healthy cells produce catalase; an enzyme that renders the highly oxidative properties of hydrogen peroxide harmless.  Many types of cancer cells produce little catalase leaving them open to the fatal or damaging effects of H202 at high enough levels. Meanwhile the healthy cells keep on trucking with no or little injury.

A newer form of liposomal vitamin C is now available for oral use. Dr Brad Weeks MD informs me it’s able to produce blood levels at least as high as those commonly used in intravenous treatments; without the same degree of cost, discomfort and inconvenience.

The above is not intended as medical advice. Neither do I suggest vitamin C is a magic bullet to cure cancers. I do however believe in people having access to information; even if it can’t be patented and generate blockbuster profits. As always, consult with your trusted healthcare professionals before making changes to your treatment.
