Powergrape® is a plant extract from the grape, rich in polyphenols, flavanols and flavanol monomers.
 Powergrape® is obtained from the grapes of Bordeaux vines, guaranteeing a high quality raw material.
As for all the extracts offered by the NAT lifeTM range of NATUREX, Powergrape® is obtained by a traditional extraction process aimed at preserving the intrinsic qualities of the plant, in accordance with the recommendations of the French food safety agency (AFSSA).
Powergrape® has a unique composition, which guarantees its efficacy. To ensure that the quality of the extract remains constant, the composition of Powergrape® is guaranteed through analysis of the active components:
- Total polyphenols (> 90%),
- Total flavanols (> 50%)
• including flavanol monomers (> 12%).
Flavanols, often wrongly called OPC1, are a very special family of polyphenols. They are the polyphenols most studied by the scientific world owing to their many properties beneficial to health. These molecules have in addition been the subject of many studies that have confirmed their bioavailability.
1 The family of flavanols is comprised of the flavanol monomers and flavanol oligomers, still called oligomeric proanthocyanidins, or more currently OPCs. |
