What are OPCs?

OPCs (plural) are complex phytonutrients that nature produces in many different types and variations. They take the form of 29 different molecules. However, not all 29 OPCs are present in every plant, and some plants have more of one specific OPCs-molecule than others. For example, not all 29 different OPCs-molecules are found in all Vitis Vinifera grape seeds.

Even if for example, the same OPCs-molecules were found in all the different grape seeds, they might not be present in identical amounts. This is because they are grown in different areas or are different varieties. For example, while two different plants may produce OPCs-molecule 21 and 22 (out of the 29), the amount of each OPCs-molecule may differ between the seeds of the two varieties.

Qualifying OPCs

For most commercially available OPCs ingredients analytical methods that tell the different types of OPCs molecules apart when measuring a specific extract are not used or available. Analyses performed today that lead to OPC-percentage or milligrams claims on most labels are imprecise and don’t describe the actual efficacy of the OPCs. These “mislabeled OPCs supplements” reinforce the false impression that all OPCs are alike, as if OPCs are a single synthetic molecule like, for example, vitamin C. A comparison based on the declaration of milligrams or percentages of OPC(s) on a food supplement is meaningless. It is a bit like comparing two cars on how they look, rather than on their actual performance.

Reliable consistency & quality

When making MASQUELIER’s® OPCs ingredients it is essential that the exact ratio between the different OPCs molecules is monitored and remains consistent, because it is only this precise composition that produces benefits. These OPCs compositions are of the highest quality with the most stringent controls, based on the efficacy of the total composition and dosage, substantiated by scientific research, are sure to deliver benefits. The only meaningful comparison for such complex phytonutrients as OPCs is a comparison based on all these elements and measured with the same analytical methods employed by MASQUELIER’s® OPCs ingredients.
