Proanthocyanidins
NEW ANTIOXIDANT DEFENDS AGAINST FREE RADICAL DAMAGE
-
UNLIKE VIRTUALLY ALL OTHER DIETARY ANTlOXIDANTS, PROANTHOCYANIDINES
READILY CROSS THE BLOOD-BRAIN BARRIER TO PROTECT VITAL BRAIN AND NERVE
TISSUE FROM OXIDATION THUS HELPING TO PREVENT SENILITY.

In vitro studies have shown proanthocyanidins to be 50 times more effective
as an antioxidant than vitamin E and 20 times more effective than vitamin
C. This powerful antioxidant action has also been demonstrated in human
and animal studies. Unlike virtually all other dietary antioxidants proanthocyanidins
readily cross the blood-brain barrier to protect vital brain and nerve
tissue from oxidation thus helping to prevent senility.

FREE RADICALS
-
Free radicals are molecular structures which contain
an unpaired electron. This unpaired electron has the ipetus to combine
with fatty acids and other substances within the
body. Each free radical is capable of destroying
an enzyme or protein molecule or complete cell. Allowed
to increase without control, free radicals can multiply geometrically.
This chain reaction can damage cell structures so badly that DNA codes
are altered and the result is what we commonly
call aging. To combat the destructive effects of
free radicals, antioxidant nutrients "donate" electrons to stabilize the
molecule and prevent its reaction with body tissues.

Oligomers ProanthoCyanidin (OPC)
-
Professor Dr. Jacques Masquelier is truly the father of OPCs. He searched
for them and discovered them following an obscure lead in explorer, Jacques
Cartiers log book from 1534. Masquelier went on to patent increasingly
refined extraction techniques for the isolation of OPCS from plant material.
His first patents were granted in 1948 (OPC from peanuts skills) and 1951
(OPC from pine bark) in France, with others following both in France and
other countries (e.g. U.S. 1969).
-
Professor Masquelier went on to fully characterize the various
oligomeric proanthocyanidins and name them both individually and as a group.
In 1979, Masquelier et. al. argued in one of their published works that
the flavonols (those polyphenols or bioflavonoids with a flavan nucleus)
"should no longer be regarded as a subcategory of flavonoids but rather
as a separate, independent class of its own."
-
Professor Masquelier labeled the small condensed forms of flavan-3-ols
"pycnogenols" a word that means "substances which deliver condensation
products". He used his word throughout his scientific writings and
wished it to become a generic term for the unique class of flavonols, the
OPCS.
-
Despite Masquelier's wishes, his word "Pycnogenol" has been trademarked
in various countries by a number of different marketing companies. The
professor has retained control over his intellectual property (the word
"pycnogenol") in only France and a few other countries.
-
Because of the loss of the name in North America, the original
"pycnogenols" invented by Masquelier must travel under the pseudonyms.
These extracts are endorsed by Masquelier, and manufactured by Berkem,
the company Masquelier selected to produce his invention in commercial
quantities.

Standardized OPC from Grape Seeds and from Pine Bark
-
Arguably this combination is the most powerful natural anti-oxidant
yet discovered.
-
OPC from grape seeds contains the gallic esters of Proanthocyanidins
(in particular:
-
Proanthocyanidin B2 - 3'-0 - gallate). These proanthocyanidin-esters
have been recently described as the most active substances in the battle
against free radicals.
-
OPC from grape seeds is marketed in France as a pharmaceutical product.
From 1972 to 1978 intensive analytical, toxicological, pharmacological
and clinical studies have been performed with OPC from grape seeds to obtain
authorization to market the product as a medicine.
-
Pine bark from the European coastal pine, Pinus Maritima, a concentrated
storehouse, not only of proanthocyanidins but nearly 40 other biologically
active compound such as naturally occurring organic acids. Arguably this
combination is the most powerful natural antioxidant yet discovered.

Proanthocyanidins Defined
-
The proanthocyanidins consist of flavan-3-ols, which are also
known as catechin and its stereoisomer spicatechin, plus "condensed" forms
of flavan-3-ols. In the world of flavan-3-ols, to "condense" means to join
together in new molecular configurations. One flavan-3-ol alone is a monomer;
two together make a dimer; three make a trimer; and so oil. Proanthocyanidins
are then, by definition, monomers, dimers, trimers and few tetramers and
penatamers of the flavan-3-ols, a special class of flavonoids formed from
catechin and epicatechin. Large condensation, or polymers, are known as
tannins and fall outside the realm of pproanthocyanidins.
-
NUMEROUS HUMAN AND ANIMAL STUDIES HAVE PROVEN THE RAPID UPTAKE AND
DISTRIBUTION OF PROANTHOCYANIDINS THROUGHOUT THE BODY. BEING WATER SOLUBLE.
THEY ARE ABSORBED ALMOST INSTANTLY. Within 20 minutes, much is absorbed
and on its way to the tissues. WITHIN ONE HOUR OF INGESTION, PROANTHOCYANIDINS
CAN BE DETECTED IN THE SALIVA. EXPERIMENTS TRACING RADIOACTIVELY TAGGED
PROANTHOCYANIDINS SHOW THAT ThEY ARE RAPIDLY ABSORBED AND FIXED TO CELL
MEMBRANES IN ThE VASCULAR SYSTEM AND CONNECTIVE TISSUES. They remain
in the tissues for about three days before being gradually eliminated,
primarily through the urine.
-
Being part of the flavonoid family, proanthocyanidins are also
active transporters of vitamin C and are known to potentiate
its antiscorbutic effects. (1) New Antioxidant Defends against Free

Double-blind study of Proanthocyanidin in chronic
venous insufficiency
-
This article reports a double-blind study comparing procyanidolic oligomers
(Proanthocyanidin) with semi-synthetic diosmin in 50 patients with symptoms
of chronic venous insufficiency. Both substances were effective in peripheral
venous insufficiency but there was a statistically significant advantage
In favor of procyanidolic oligomers (Proanthocyanidin) with regard to rapidity
and duration of action.

Questions & Answers About Pycnogenols
-
Q: What are Pycnogenols?
-
A: Pycnogenols are a natural plant product made from the bark of the
European coastal pine. Pinus Ivaritima. or from grape seeds.
-
They have. beyond question. been shown 10 have powerful free radical
Scavenging activity. and can counter act the effects of aging.
-
They are a concentrated special class of waler-soluble bioflavonoids
that are almost instantly bioavailable in man.
-
Q: What are Bioflavonoids?
-
A: Bioflavonoids are a group of low molecular weight plant substances
with recognized antioxidant (free radical scavenging) properties and with
the ability to inhibit the cenlain enzymes which cause inflammation in
the body.
-
Q: Are all bioflavonoids the same?
-
A: No. there are over 20.000 bioflavonoids. Some are more active than
others. some are more valuable than others. A few which have shown biological
value in the laboratory have not performed well when manufactured in commercial
quantities and when tested in living aniimals.
-
Q: What makes Pycnogenols different?
-
A: They are bioavailable. Numerous human and animal studies have proved
the rapid uptake and distribution of Pycnogenols throughout the body. Being
water soluble. they are absorbed almost instantly. The bioflavonoids that
make up Pycnogenols are special. They are called proanthocyanidins. Pycnogenols
are 85% to 95% proanthocyanidins.
-
Q: How pure are Pycnogenols?
-
A: Very pure. They are 85% to 95% pure proanthocyanidins. The few remaining
percentages of Pycnogenols have been fully identified as plant fibers.
nutrients and trace amounts of harmless plant substances such as cellulose.
Practically no other natural plant material has been so fully analyzed.
There are no solvent residues. natural or synthetic additives or other
dilutents in Pycuogenols.
-
Q: Are Pycuogenols at all toxic?
-
A: Not at all. Pycnogenols have gone through extensive testing at prestigious
research centers such as the Pasteur [Institute.
-
Huntington Institute. and others over many years to confirm their purity
and safety. Pycnogenols are non-toxic. non-mutagenic. and
-
non-carcinogenic.
-
Q: How quickly do Pycuogenols act in man?
-
A: Within 20 minutes most are absorbed and on their way to the tissues.
Within one hour of ingestion Pycnogenols can be detected in the saliva.
-
Q: How long do Pycuogenols remain in the body?
-
A: Three days. What comes in circulates in bodily fluids and is held
in the collagen for 72 hours. It is then gradually eliminated through the
urine (primarily) and perspiration (secondarily).
-
Q: How much should I take?
-
A: The amount varies from person to person. Larger people can use more.
Therapeutic doses are usually 10 milligrams per bIbs of body weight This
means a 160 pound man or women would take about 160 mgs. at first to reach
tissue saturation. Saturation is reached in 7 to 10 days. Then the dosage
can be cut back to one-half or less - about 50 to 60 mgs. per day - to
simply replace what is eliminated each day.
-
Q: Are Pycnogenols acidic like ascorbic acid or alkaline like some minerals?
-
A: Pycnogenols are acidic. They have a low pH of 2.5 to 4.0. A healthy
stomach will carry a pH of 1.5 to 2.0. The pH of a mixed meal in the stomach
is commonly between 4.5 and 5.5. These numbers tell us Pycnogenols are
beautifully compatible with human digestion
-
Q: Who discovered Pycuogenols?
-
A: Dr. 1. Masquelier of the University of Bordeaux isolated, identiified,
and characterized Pycuogenols. He, in fact, invented the name Pycuogenols
to denote the highly bioavailable, water soluble, class of special bioflavonoids
he had discovered.
