Grape Seed Extract supplement, 100 mg
Standardized 95% Polyphenols
60 Grape Seed Extract Capsules
Grape seed extract is a Dietary Supplement.
Each capsule of this grape seed extract supplement provides 95 mg of potent polyphenols.
Grape seed extracts have compounds called procyanidolic oligomers (PCOs). Other sources of PCOs are berries, green and black teas, and red wine. PCOs are powerful antioxidants, perhaps much greater than vitamins C and E. They also inhibit a number of enzymes that degrade connective tissue such as elastase, collagenase, and hyaluronidase. This grape seed extract is of extremely high quality full of potent antioxidants called polyphenols. Polyphenols include anthocyanins, procyanidins and related beneficial compounds. Grape seed extract is a natural plant product made from the grape seed (or pip). Grape seed extract is rich in procyanidins, a special class of water-soluble bioflavonoids. *

Grape seed extract product questions
Q. Have there been any studies with grape seed extract supplements in humans that people have taken for several years to see what benefits and grape seed extract side effects can occur?
A. We are not aware of long term, human grape seed extract supplement research. As with most herbs and natural products that have not had long term trials, it is best to take breaks from use, for instance one week a month. Grape seed extract supplements appear to be safe, but just to be cautious, it is a good idea to take a few days off each month.
Q. Which is more
potent as an antioxidant, grape seed extract, mangosteen, goji berry,
acai berry, carnosie, acetyl l-carnitine, pomegranate extract or cacao
A. Rather than focusing on comparing the antioxidant benefits of different supplements, we prefer people alternate their use rather than relying on one particular supplement. All the herbs and nutrients you mention are healthy additions to one's supplement program, but taking them all together may not necessarily be healthy. You can take 2 or 3 a day and alternate their use.
Q. Thank you for
the information you have made easily accessible. I appreciate that you
make supplements available not easily purchased elsewhere. I have been
using TwinLab Grape Seed Extract for years and have been consistently
impressed with its quality. I had some experience with an inferior,
substandard version. Now I am perhaps confusing "inexpensive" with
"inferior." When I read the Club Natural label and compare it to the
TwinLab label, it seems that the products should have equivalent
quality. Yet because the Club Natural version is so much less expensive
than any price for which I can buy the TwinLab, I seem to think that
means the product itself is inferior to TwinLab's. Can you explain why
this grape seed product could be high quality, yet not expensive?
A. The price of a supplement does not necessarily reflect the quality. Big companies such as Twinlab may have a high overhead to cover corporate costs. Club Natural is a smaller company and since web site sales are very competitive, we keep our prices low to build a strong customer base. It is possible that as we gain more customers and market share, we could raise our prices.
