Grape Seed Extract powder is obtained after the process of extracting, drying, crushing and refining whole grape seeds from the vitis vinifera tree or simply the common grape. Its most important chemical content are the OPCs or oligomeric proanthocyanidins which possess a broad spectrum of health-promoting properties.
Proanthocyanidins
are the principal vasoactive polyphenols in red wine responsible for
significantly reducing the risk of heart disease and maintaining a healthy
heart. They are present at higher concentrations most especially in wines
coming from the areas in southwestern France and Sardinia with physical
manifestation on longer life expectancy of the people in the area. lancer

Previous
research showed the total oligomeric proanthocyanidin content in red wines
including catechins is substantially higher than that in white wines
Vitamin
C and vitamin E are some of the best known antioxidants that we have been
exposed to but studies show that the antioxidant properties of
proanthocyanidins are 20 times more potent than vitamin C and 50 times more
powerful than vitamin E. antracol
Grape
seed extract powder, with its powerful OPC content is able to protect us from
the harmful effects of environmental degradation such as air and water
pollution, cigarette smoking, and harmful emissions from vehicles and
factories.
The
beneficial effects to people may include healthy blood fat, decongested blood
vessels, low blood pressure, low cholesterol level, preventing blood vessel
scleroses, dropping blood viscidity and preventing thrombus formation. mahyco
Additionally,
studies have shown that OPCs may prevent cardiovascular diseases by
counteracting the negative effects of high cholesterol in the heart and blood
vessels
The
proanthocyanidin content in pine bark and grape seed extracts is known to
strengthen our blood vessels and promote efficient delivery of oxygen to the
cells. Proanthocyanidins also protect cell membranes by providing the nutrients
necessary in reducing capillary permeability and fragility. The
proanthocyanidin compound is most abundantly found in the bark of the maritime
pine and in grape seeds called pips.
Grape
seed extract powder can be used as a treatment option for skin disorders by
stabilizing collagen and maintaining the elastin in the connective tissues that
support our organs, joints, blood vessels, and muscles. madhulika
Pycnogenol,
an OPC obtained from pine bark extract was shown to delay the progress of
retinal edema and visual acuity especially in the infancy stage of diabetic
retinopathy.
Proanthocyanidins
are known to suppress the production of a protein called endothelin-1 that
causes constriction of blood vessels. Endothelins are proteins that cause blood
vessels to constrict and blood pressure to rise and normally works with other
mechanisms to maintain its balance but causes hypertension when the balance is
lost. Thus the use of Grape seed extract powder with substantially high OPCs
will significantly lower down blood pressure, reduce the risk of a heart attack
and minimize migraine attacks. rasi
seeds
Many
plants like apples, cocoa, cinnamon, grape seeds, grape skin, red wines and
pine bark are known to contain substantial amounts of proanthocyanadins but the
berries of the chokeberry plant are known to have the highest concentration of
these antioxidants. Bilberry. cranberry, black currant, green tea, black tea
also contain these flavonoids.
Apples
also contain, on average per serving, eight times the amount of
proanthocyanidins found in red wines with the highest concentration found in
the Red Delicious and Granny Smith apple varieties. Proanthocyanidins have long
been sold as a nutritional supplement in Europe since the 1980s. It is only
recently that it was introduced in the US market.
