What
is OPC? ( OPC = Oligomeric Proanthocyanidins )
OPCs stands for the term Oligomeric Proanthocyanidins
which is also known as “PCOs” for procyanidolic oligomers
or Proanthocyanidins. OPC is a member in the bioflavonoid
family. Some researchers also call these molecules “pycnogenol.”
OPC (Oligomeric Proanthocyanidins) became famous in the
early 1990s. It is now known as a key element to antioxidant
activities, stabilization of collagen and maintenance of
elastin. OPCs are wildely used in many anti-aging supplements
today around the globe.
OPCs were first noticed by Dr. Jack Masquelier
of the university of Bordeaux (France) back in the mid 1900s.
He first discovered this magical element from an ancient
native American's tea recipe. This tea recipe uses pine
barks and needles as a main fragrant component. The tea
surprisingly saved a crew of explorers from scurvy. Dr.
Masquelier found that pine bark contains oligomeric proanthocyanidins
(OPCs), which boosted the activity of vitamin C (now recognized
as a primary anti-scurvy nutrient) present in the bard and
also offered its own independent health-promoting properties.
He soon found the similar material from the grape seed and
started to study the OPCs in grape seeds and red wines.
Quite recently, analysis of the molecular structure of red
wine have now isolated one particular type of flavonoid
in red wine - OPCs - as being particularly beneficial for
protecting the heart and blood vessels. OPCs are now know
as the most effective element in fighting against the free
radicals which make them to be the main source in all antioxidant
supplements.

What
is Free Radicals (Oxidation Process)
In the early days of medical research,
free radicals is defined as the molecules in which the electrical
charge is not balanced. These molecules contain a free electron
which makes them to be negatively charged. This unbalanced
electrical energy makes the free radical highly reactive.
It seeks out balanced molecules from which it attempts to
acquire an electron in order to attain electrical equilibrium
for itself. While the free radical may have attained its
electrical equilibrium by gaining the electron, it creates
a new free radical out of the previously balanced molecule,
which then sets off on its quest to snatch an electron and
so on. Although this type of activity is necessary in that
is supplies the biochemical electricity from which our cells
produce energy in order to carry out the body's most basic
biological processes, an excess of free radicals can attack
the structure of our cells.

What
Causes Oxidation in Human Body?
Modern-day society has created an environment
in which our bodies are overloaded with free radicals. The
everyday sources of free radicals includes:
- Food preservatives increase free radical levels; highly
processed foods have little antioxidant value. In another
word, people who always eat well cooked food such as BBQ,
Deep Fried, Steamed, Boiled foods are likely to have less
antioxidant in their body because they do not get enough
from the daily food.
- Ultra Violet radiation induces free radical formation
in our skin, which may lead to skin cancer. So, for people
who always get exposed to the sun light, you may need extra
vitamin E and other extra antioxidant to keep your skin
healthy.
- Daily electronic radiation sources
such as cell phone signals, microwave and x-rays promote
increased free radical activity.
- Fatty foods increase levels of LDL
cholesterol in blood, which are readily oxidized by free
radicals. Dr. Ursini and colleagues from University of Padova
once conducted a convincing experiment. He fed a group of
men and women a high fat meal, and some of them drank red
wine as they ate. Dr. Ursini found that the level of oxidants
- substances that lead to clogging of the arteries - was
raised immediately after the meal. However, those who drank
the wine had comparatively lower oxidant level than the
ones did not drink. This is because there is rich OPCs in
the red wine that can help to neutralize the unbalanced
molecules in order to be beneficial for protecting the heart
and blood vessels.
- Excessive exercise promotes free radicals
activity by increasing the body's consumption of oxygen.
This is another reason for heavy work out programs does
not necessarily guarantee them from getting seriously ill
or develop the modern day killer diseases. In fact, excessive
exercise may possibly cause the body to generate more free
radicals which will leads to serious health problems.
- Daily stress press key defense mechanisms
of the body and leaves us vulnerable to the effects of free
radical activity. This is also one of the major reasons
for people who lives in a high stress environment or works
in a stressful environment are likely to develop modern
day killer diseases such as cancer.
- The industrial pollution, auto waste
gas and furnishing chemicals all emit free radicals as they
dissipate into the air.
- Cigarette smoke is dense with free
radicals, one type of which lasts several days in the air.
There have been many cases in people that are working in
smoke permitted environments develop deadly diseases like
cancer. The second hand smokers are the victims of cigarette
smoke triggered oxidation.

What
Does Oxidation Leads To? Oxidation and Aging.
Free radicals can cause disruption of
DNA and RNA synthesis (necessary for cellular repair and
replication), disturbance of protein synthesis (necessary
for cellular energy), and destruction of cellular enzymes
(necessary for chemical processes). Free radical disruption
of cell metabolism contributes to cellular aging. The free
radical theory may explain many of the structural features
that develop with aging - including the lipid peroxidation
of membranes, formation of age pigments, cross-linkage of
proteins, DNA damage in cell nuclei and mitochondrial chromosomes
and decline of mitochondrial function.
Age related impairment of enzymes enhance
production of reactive oxygen species (ROS) through increased
electron leakage. More than 100 human clinical conditions
are now associated with elevated levels of ROS - including
atherosclerosis, heart disease, cerebrovascular incidents,
diabetes, arthritis, autoimmune diseases, cancers and aging
itself.
Free radicals and ROS both cause oxidation.
In the body, degradation results from oxidation. We need
oxygen to survive, yet our breathing allows the diffusion
of free radicals and free radical-inducing chemicals into
our lungs that help along the aging process. Cumulative
oxidative damage to the cells and tissues of the body is
an unfortunate adverse result of the normal course of oxygen-based
metabolism. Left unchecked, oxygen would cause unlimited
oxidation and, ultimately, death. Fortunately, the body
is equipped with a way to counteract oxidation - through
antioxidants.

Where
do we get Antioxidant? Why OPC?
Our bodies produce antioxidants, however
we do not carry out these syntheses of chemical protectants
to a sufficient extent. We get additional antioxidants through
food, specifically fruits and vegetables. All plants produce
abundant quantities of antioxidants. Plant based antioxidants
are known as "flavonoids" (a term that is now
used interchangeably with "bioflavonoid"). Scientists
have identified over 4,000 different flavonoids to date,
and they are the most readily absorbed by the human body
type of natural antioxidant.
It is a fortunate and also an unfortunate
for use using technology based farming activities. The fortunate
part is that we have much more selections in vegetables
and fruits on our table. The unfortunate part is that all
the fertilizers, excess storage (from farm to storage then
to market), less mineral based soil all effects the vitamin,
mineral and bioflavonoid. Plus an additional selections
on non-fruit / vegetable food sources (meat, diary products
etc.) leave us even less room for bioflavonoid intakes.
Therefore, nutritional supplementation of antioxidizing
nutrients becomes essential to our wellness. Scientists
have discovered that their free radical scavenging activities
of antioxidant nutrients can be quite varied, largely due
to the structural differences. Thus, the benefits of supplementation
with these nutrients can be quite varied. For best results,
each of us should, first an foremost, make an effort to
consume a daily diet that is as high in fresh, unprocessed
fruits and vegetables as possible. Then, we can get an extra
boost of antioxidants by supplementing with a high-quality,
natural dietary supplement, the selection of which should
be matched to our individual health needs.
OPCs (oligomeric Proanthocyanidins) are
becoming recognized as one of the most potent categories
of antioxidants discovered to date. Leading OPC researcher
Dr. Bagchi, along with colleagues at Creighton University,
has published numerous scientific studies on the free radicals
scavenging activity of Grape Seed Proanthocyanidin Extract
(GSPE). Dr. Bagchi and colleagues have remarked that GSPE
is "highly bioavailable and prodies significantly greater
protection against free radicals and DNA damage than vitamins
C, E, and beta-carotene." Earlier work by Dr. Bagchi
documented that GSPE inhibited 78-81% of free radicals exerted
on cells in the lab setting, whereas vitamin C inhibited
by a mere 12-19% and vitamin E inhibited by only 36-44%.
OPCs become active antioxidants in the
bloodstream in a remarkably short time period. Dr. Nuttall
and team from University of Birmingham (United Kingdom)
found that a five-day course of GPSE was able to significantly
raise blood levels of total antioxidants. Moreover, on the
last day of the study, Dr. Nuttall found that GPSE raised
total antioxidant activity by over 11% in just one hour
after supplement was consumed.
Some evidence suggests that OPCs can
reduce the discomfort and swelling of varicose veins and
decrease the edema (swelling) that often follows injury
or surgery. OPCs are also marketed for preventing heart
disease, revitalizing aging skin, treating allergic conditions
and reducing the tendency toward easy bruising, but there
is little meaningful evidence as yet that they are effective
for these purposes.

OPCs
(PCO) Supplements
Because OPCs are frequently destroyed
when foods are processed, it is unlikely that most Americans
get this level of OPCs by consuming foods in the everyday
diet. Here are some tips for selecting a high quality, efficacious
OPC supplement.
- Extraction sources: Currently, there
are three major sources for OPCs supplement formation. They
are Grape Seed, Pine Barks and Red Wine. Grape Seed extracts
is know to be the best source out of all three.
- Extraction process: it is very important
that the OPC supplement you select delivers a high degree
of oligomeric proanthocyanidins (OPCs). Scientists have
found that the method by which extracts of grape seed, red
wine, and pine bark can greatly affect the ratio of OPCs
to simpler catechism.
- Daily Dosing: OPCs do not last long
in the bloodstream, so we need to ingest them daily in order
to maintain their protective effects on the blood. Consequently,
it becomes important to select an OPC product that is easy
for us to take and is proven to give us a useful does of
OPCs.
Among many selections of OPCs supplements,
I personally suggest the Grape Seed (PCO) Phytosome from
Enzymatic Therapy. It contains procyanidolic oligomers (PCOs)
which meet or exceed the quality of Pycnogenol from pine
bark. PCOs extracted from grape seeds are the preferred
form recommended by health care practitioners in France.
Grape Seed (PCO) Phytosome surrounds the water-soluble PCO
molecules with fat-soluble phosphatidylcholine molecules.
This combination is easily absorbed and highly bioavailable,
so more PCOs are delivered to body tissues.
