Nutritional Supplements: The Amazing Vitamin
C

The real facts about Vitamin C
may surprise you. First of all what is Vitamin C? Vitamin C is
a water soluble vitamin. Unlike the oil soluble
vitamins such as A and E, Vitamin C cannot be stored by your
body. Since Vitamin C is not
stored by your body, we need to get it from our diet or from
supplements.
But Can't Our Bodies Just Make Vitamin C?
Great question! Most animals have the ability to make their own
Vitamin C. And make it they do... lots of it. It is estimated
that if we had the ability to make our own Vitamin C we would
make between 3000 an 10,000 mg every day... and 3 to 4 times
that amount if we were being stressed by infection.
Unfortunately, humans along with guinea pigs, fruit bats and
gorillas are the only mammals that need to ingest our daily
dose of Vitamin C. The only vitamin we humans have the ability
to make is Vitamin D... and we need the sunshine to help us do
that.
Some very exciting facts about Vitamin C have sprung up within
the last few years. First off, Vitamin C along with Coenzyme
Q10 (CoQ10), have been called the most essential of the
"essential nutrients." That is, without an adequate supply of
these two, you die. Maybe not today or tomorrow, but certainly
years sooner than the folks with optimal levels of both in
their bodies.
Arrrrr!!! Shiver Me Timbers!
Remember the stories about the sailors of old and the disease
they contracted during long voyages called scurvy? Scurvy was
nothing more than not having enough Vitamin C in their bodies.
Without an adequate supply of Vitamin C, the blood vessels did
not have enough collagen to repair themselves. Some of these
sailors literally bled to death through cracks in their blood
vessel walls.
Fortunately, in 1747 a Scottish doctor got a clue about Vitamin
c and linked citrus fruits with a decreased incidence of
Scurvy. Towards the end of that century, the Brits began
sending along lime juice with their sailors on long voyages.
Now you know why British sailors are called "limeys."
Facts About Vitamin C and its Antioxidant Properties
If you've read the section of my site on the
facts about Vitamin E, you've no doubt read about what an
antioxidant does. If not we can review quickly.
The cells of your body are under a lot of stress... oxidative
stress. Oxidative stress occurs when highly unstable molecules
called free radicals roam freely throughout your body.
Free radicals are a by-product of not only the normal metabolic
processes of your cells but also your environment... things
such as air pollution, sun exposure, industrial chemical
exposure, ozone, nitrous oxide (from auto exhaust), cigarette
smoke, alcohol consumption and so on.
Free radicals damage cell membranes and DNA and can result in
changes to your cells that cause life threatening chronic
diseases down the road. When your cells are being damaged by
these free radicals, we say your cells are experiencing
oxidative stress... and one of the facts about Vitamin C is
that it is an antioxidant and can significantly neutralize the
free radicals and the damage to your cells that cause oxidative
stress.
Facts about Vitamin C and Heart Disease
One of the facts about Vitamin C that we feel is most
significant is the role Vitamin C plays in the production of
collagen.
Collagen is a protein. It is the connective tissue that holds
our bodies together and keeps us from falling apart. Collagen
is found in your skin, bones, ligaments, tendons, liver,
cartilage, bone marrow and blood vessels.
Collagen is essential for the repair of our bodies. Without
collagen our bodies don't heal. And without Vitamin C we don't
make collagen.
What Does Collagen Production Have to Do With Heart
Disease?
Remember the facts about Vitamin C above and the sailors with
scurvy? They weren't getting any Vitamin C. So when their blood
vessels cracked, no collagen was being produced to repair the
cracks.
Why do your blood vessels crack in the first place? Well
consider this. Your heart beats about 4000 times every hour.
That's 96,000 times a day and 35,040,000 times every year (yes
that's million)! The blood vessels of your heart are being
squeezed and released that many times as well.
Imagine you were to run over a garden hose laying in your
driveway that many times. Do you think it might soon develop
some cracks?
Although your body has a difficult time repairing those cracks
in the complete absence of Vitamin C (and hence scurvy), most
folks in the developed world get just enough Vitamin C to keep
scurvy at bay... but not much more.
Problem is, as this sub-optimal amount of Vitamin C in their
body is repairing with collagen, it's not quite enough. Your
liver then determines that the repairs are not being made quick
enough and sets about to produce a special form of LDL called
lipoprotein-a.
Lipoprotein-a is very sticky and acts as a putty to fill in the
cracks that the lack of collagen left behind. Great right? Leak
stopped.
Well the leak is stopped yes, but being as sticky as it is,
lipoprotein-a catches and glues down all the other LDL (bad
cholesterol) that floats by. This action results in plaque
build-up inside the vessel walls and can eventually close off
these blood vessels... and we all know what that means!
Facts about Vitamin C and Cholesterol
Can Vitamin C lower cholesterol? A relationship has been shown
experimentally between high levels of Vitamin C and low levels
of cholesterol. An article appearing in the National Library of
Medicine shows that Vitamin C provides the same mechanism for
inhibiting the production of cholesterol as do cholesterol
lowering statin drugs.
The American Heart Association also reported that Vitamin C
lowered LDL cholesterol in children who were predisposed to
high cholesterol.
The facts about Vitamin C also show that Vitamin C lowers
cholesterol without the dangerous side effects of these statin
drugs. Statin drugs have been shown to inhibit the production
of another essential nutrient called Coenzyme Q10 (CoQ10).
Decreased levels of CoQ10 result in significant muscle myopathy
(wasting away). And since the heart is a muscle, statin drugs
have been linked to Congestive Heart Failure (CHF).
More Facts about Vitamin C
Vitamin C has been shown to lower blood pressure, reduce the
risk of Alzheimer's when taken with Vitamin E and cut your
chances of having a stroke.
Why is that? Remember the facts about Vitamin C above as an
antioxidant? Well, most researchers agree that Vitamin C's
powerful antioxidant properties are responsible. By
neutralizing the cell damaging effects of those free radicals
running around in your body, Vitamin C works to keep your cells
healthy and free of damage. And if your cells are healthy, you
are healthy!
Vitamin C is also known to protect the immune system. Vitamin C
aids in the manufacture of white blood cells. White blood cells
destroy viruses and bacteria.
Also remember the facts about Vitamin C as aiding in the
manufacture of collagen? Well collagen being the connective
tissue that holds our skin together, our skin is what keeps
pathogens out in the first place.
Yeah, But I Drink My Glass of Orange Juice Everyday... Well
Almost
What are the facts about Vitamin C concerning the amount you
should take? Well who do you want to believe? The official U.S.
Government RDA for Vitamin C is 60 to 90 mg. Some would argue
that this level does nothing more than ward off scurvy. They
would also argue that these levels do nothing to prevent
chronic, long term, debilitating diseases.
An article in the American Journal for Clinical Nutrition
reports on a study done on antioxidant vitamins and coronary
heart disease risk. The study looked at 9 other studies which
included participation by Harvard School of Public Health and
Tel Aviv University, Tel Aviv, Israel.
Conclusions: "The results suggest a reduced incidence of major
CHD (coronary heart disease) events at high supplemental
vitamin C intakes."
How high was the daily Vitamin C intake of the 293,172 patients
during this ten year study? Above 700 mg!
Ok, But Is Vitamin C Safe?
In an article titled "Vitamins E and C Are Safe Across a Broad
Range of Intakes" published in THE AMERICAN JOURNAL of CLINICAL
NUTRITION, a large study concluded that Vitamin C supplements
of up to 2000 mg per day were safe for most adults. Exceeding
that limit could result in gastrointestinal upset or mild
diarrhea.
