Do you know that Vitamin C depletes your body of many mineral and trace mineral nutrients?
The truth is that your kidneys cannot excrete Vitamin C at all without combining it with an important mineral nutrient such as calcium or magnesium or zinc. Every single molecule of excess Vitamin C that gets dumped in your urine steals from you an important mineral nutrient.
Do you know that Vitamin C will particularly cause a deficiency in the essential trace mineral copper?
Do you know that excess Vitamin C will actually cause high cholesterol?
Do you know that excessive Vitamin C can destroy the pH control of certain patients making them more susceptible to certain physical and mental conditions?
Do you know that Vitamin C depletes the body of important minerals such as calcium and magnesium?
Do you know that Vitamin C can so deplete a person of copper that the blood vessels begin to break down and the heart is weakened?
Do you know that Vitamin C can elevate cholesterol in certain patients?
Do you know that excess Vitamin C can damage the DNA (the genetic material inside each of your cells) and also damage cell membranes because of its oxidant (not anti-oxidant) activity?
Do you know that because it is such a strong oxidant (not anti-oxidant) more than 500 milligrams of Vitamin C will cause the formation in your DNA of oxoadenine, a powerfully damaging toxin which particularly will harm the heart and other organs?
Do you know that Vitamin C will convert the mineral iron to a form that damages the blood vessels and leads to hardening of the arteries and heart blockage?
Do you know that Vitamin C can auto-oxidize, and instead of being an anti-oxidant to protect you against free radical damage, will actually cause free radical damage?
This oxidation of Vitamin C occurs most easily in the presence of minerals such as iron, manganese, and chromium. When excess Vitamin C is taken with these mineral nutrients you are particularly likely to suffer free radical damage.
Do you know that excess Vitamin C will cause the formation of the toxic chemical pentosadine, a marker of premature aging and tissue destruction?
Do you know that Vitamin C causes destruction of proteins in your body that will accelerate the aging process?
This acceleration of aging by Vitamin C is particularly pronounced in anyone with a diabetic tendency. The protein destructive effects of Vitamin C are particularly associated with cataract formation.
Do you know that Vitamin C in doses greater than 180 milligrams is a total waste of money because it is not absorbed and tends to cause gas and bloating in your intestinal tract?
Eighty to ninety percent of Vitamin C is absorbed up to a dose of 180 milligrams, but beyond that, absorption decreases rapidly so that at 5000 milligrams doses only 24% is absorbed, while the rest just irritates your digestive system.
This is apparently from a Chiropractor's member-only site?!? Ronald J. Grisanti ? YourMedicalDetective.com? Although your link works.
We looked over his web sites (free portion) and I would agree with about 90% of the stories this fellow has posted. He does not appear to be overly influenced by Big Pharma. He has simply fallen for much of the false information posted by "naturalists" and others around the Internet. And vitamin C causing harm is always big news and makes people curious.
I suppose we should take the time to debate each and every point.. Big sigh..
#1 Do you know that Vitamin C depletes your body of many mineral and trace mineral nutrients?
The inaccurate word is deplete
. A better word is regulate or balance. As Ralph points out, most living beings make their own vitamin C 24/7 and they would all suffer such imbalances if vitamin C actually depleted minerals.
#2 The truth is that your kidneys cannot excrete Vitamin C at all without combining it with an important mineral nutrient such as calcium or magnesium or zinc. Every single molecule of excess Vitamin C that gets dumped in your urine steals from you an important mineral nutrient.
If true, same logical inconsistency as #1 and same problem with all the other animal species.
Searching for any support for the assertion that "kidneys cannot excrete vitamin C at all without combining it with an important mineral" I found this excellent description http://www.exrx.net/Nutrition/Antioxida ... aminC.html
(Does not answer this particular question, but is a great reference.)
Medicine rarely studies more than 200 mg of vitamin C making it difficult to find a scientific reference for these assertions regarding higher dosages. When Pauling describes the vitamin C "pumps" in the kidney, he does not mention a requirement for a mineral, but it is likely that most ascorbate in the blood is bound to something, e.g. sodium, so that any excreted via the kidney above the threshold would be attached to some negatively charge ion. If anyone finds more information on the renal threshold, please post.
Rather than itemize, does anyone have a particular question? Yes, Vitamin C regulates cholesterol, so that in people making too little, it would actually raise cholesterol to around 180 mg/dl. (See Ginter in Clinical Studies). So the statement that "vitamin C elevates cholesterol in some people" is true, but a fairer assertion is that it lowers cholesterol in the vast majority, etc. All of these assertions fail for the same reason, they are not balanced.
The not absorbed argument has been dealt with too. If not absorbed, vitamin C causes gas and diarrhea, so the 18,000 mg I take daily is "absorbed". The argument is utilization.
Oh and if you read his 4 references - abstracts - there is no support for any of his assertions. The first showed a slight depletion in copper - but only in copper deficient monkees. Actually, I found this study reassuring as there is no strong effect of higher vitamin C on copper levels.
