Although grapes are already rich in essential nutrients,
the extract of its seeds is even more powerful. The extract of seeds of
Grapes comes from the oil made from crushed whole red grapes and is a
excellent source of antioxidants.
Because unlike oil, it contains these antioxidants
exceptional: oligo-proanthocyanidins or OPCs .
The OPCs :
The story of oligo-proanthocyanidins only begins
However, not with grape seeds. It all began in 1534 with a
expedition of the navigator Jacques Cartier . While the nautical expedition is
stuck in the ice of the Saint-Laurent, the crew of Jacques Cartier is
victim of scurvy. He was then treated by the Amerindians . They concocted
infusions made from pine bark.
More than 400 years later, a French scientist seeks to
discover what could have saved the French sailors. He then discovered some
compounds of the flavonoid class. In the 1950s, he developed a
method of extracting oligoproanthocyanidins (OPCs) present in the bark
of pine. He later became interested in grape seeds in which he
finds similar compounds. Grape seeds being more easily
accessible in France, the professor then began intense research.
These make it possible to highlight the value of
oligo-proanthocyanidins and this since the 1970s.
Since then, scientific advances have made it possible to better
identify the virtues of these molecules. It is now proven that
Oligoproanthocyanidins have real health benefits.
Grape seed extract has been the subject of numerous
studies that have made it possible to determine its various effects on health.
Oligoproanthocyanidins are even more powerful antioxidants than
vitamins E and C and in addition, potentiate the latter. They play a role
plays an essential role as a bulwark against free radicals.
The qualities of this extract are very disparate on the
market. It is absolutely necessary to choose a grape seed extract that is sufficiently
titrated in OPC to make it active. The OPC content can be up to 75%.
Beware of manufacturers who confuse consumers
voluntarily polyphenols and OPCs. OPCs are part of the family of
polyphenols. The most concentrated extracts are 96% polyphenols, including
75% OPC (and not 96% OPC).
