The Question of Vitamin C and Porphyria
Porphyrin loss of hydrogens from the porphyrinogens generally
turns them into porphyrins. These are which are the cause of the
porphyrias.
Hydrogen or electron donors, such as vitamin C, are believed to
inhibit the transformation of porphyrinogens to porphyrins. Also,
vitamin C will facilitate the conversion of the products to
cytochromes. Another name for Vitamin C is that of ascorbic acid.
There is also the conversion to hemoglobin, reducing the buildup
of intermediate products in the above pathway.
Some forms of porphyria are believed to involve the mitochondria.
This causes a reduction in energy conversion. This can cause a
spirt of chronic fatigue. Many porphyrics talk about having
chronic fatigue.
One of the things to be aware of in the use of large amounts of
vitamin C is that Vitamin C is thought to be one of the causes of
kidney stones. Researchers think that anything in excess of 1,000
grams of ascorbic acid in one day may lead to the production of
kidney stones.
It is interesting to note that porphyria patients sometimes talk
about losing salt or craving salt. Salt is conserved in the
kidneys by the exchange of the sodium ions for hydrogen ions.
During every acute attack it is important to be sure that you
maintain your electrolyte balance. Sodium is a part of that
electrolyte balance. One may consider that as sodium levels
decrease, additional stress is placed on the hydrogen ion
sources. This will cause an increase in the generation of
susceptible individuals.
One such stress may be the need to generate more cytochromes
during exposure to environmental toxins or therapy with
inappropriate pharmaceuticals.
Studies show that about one -fifth of all pharmaceuticals are
detoxified by the cytochromes. This will then place additional
burdens upon the porphyrin related pathways. Fun right?
So the bottom line is that individuals with porphyria may be
seriously harmed by doctors without specific training and
information related to porphyria. Be sure to interview physicians
before you allow any testing or consultation. Most will allow a
short interview. Be specific and ask the right questions geared
at your specific needs.
Not all porphyria victims report benefit from high doses of
vitamin C, but there are often other issues involved, such as
yeast infections. Many women porphyrics have expressed the burden
of the continuous strong of yeast infections. These other
conditions need to be addressed before benefits of high dose
(bowel tolerance) vitamin C therapy can become evident.
Yeasts are a particular problem.
When a porphyria patient utilizes a high carbohydrate it can at
the same time encourage yeast overgrowth.
Sometimes various C Salts are useful. If one listens to what
one's body is saying, one stands a better chance of doing the
right thing.
Porphyria patients often report that doctors, particularly those
in HMO's, are not well versed, and sometimes appear unwilling to
run all the proper tests to confirm a diagnosis of porphyria.
Even in private care, misdiagnosis and improper treatments are
not uncommon.
Indeed as many porphyria patients say improper and often
dangerous treatments are the rule, not the exception, when
dealing with doctors who have no special training for dealing
with porphyria. Unfortunately for porphyria patients a great
majority of physicians still do not know about this disease.
As porphyria patients, each of us must take personal
responsibility in sharing all porphyria information with the
physicians who treat us. Through such exchanging of ideas comes
knowledge and eventually help for the porphyric patient!
