Here we quote the slogan of some other vendors
"OPC 95 - the strongest antioxidant in the world, most likeley the best OPC in the world""unbeatable value for your money". Now, let’s look at this in more detail: Other providers label their product as OPC 95. This term is also used by raw material suppliers who promise 95% OPC, but when questioned about the tested OPC content, it is found they usually tested the polyphenols. It should be clarified that these are two very different claims! Likewise, e.g "105 mg of OPC per capsule"is declared. At 95 % OPC, this would amount to 110.5 mg grape seed extract per capsule. The OPC content has not been verified with an analysis certificate. A provider from Switzerland labeled his product as 300 mg of OPC, but after analysis of the product only 5 mg were found. It is not know where the grapes came from. Often grape seeds that have been cultivated in China are used, leading to extremely low prices. In comparison, Biotikon offers 450 mg grape seed extract per capsule, increasing the quantity by four times. The OPC content (240 mg) is based on an analysis. The analysis is published. The grape seeds come from France which provides the highest quality of grapes.
Conclusion: By taking a closer look at the cheaper product, you may find that it might not have a better price performance ratio (performance to cost ratio).

OPC 300 mg: the advertising made by competitors promises 300 mg of grape seed extract content, meaning that the OPC content would have to be 100 %. Here the grape seed extract and OPC content are claimed to be equivalent.

The term OPC 95 %:  OPC 95 is used by many manufacturers to describe their OPC quality, but actually it usually indicates a lower OPC quality. Often this does not refer to the OPC content, but to the analysis value according to "Bate Smith", stating the ratio value which is not applicable to measure the exact amount of OPC. Otherwise he refers to the polyphenol content. The term OPC 95 % does not mean that 95 % of OPC is contained. When buying OPC, ask for the original certificate of analysis (CoA) from an independent German Analysis Institute which identifies the OPC content.

OPC 400 mg, 450 mg, 500 mg: Again, you should make sure that these statements do not refer to the capsule weight, but to the actual OPC content.

OPC Analysis, OPC Verification

OPC is a worldwide recognised substance, but few mastere the difficult subject of OPC analysis. The OPC analysis certificate should always identify the OPC. It is important that the OPC content is measured directly by analysis in the grape seed extract. We also recommend to confirm the OPC content through a German certificate of analysis from a German laboratory. It is also important that the residence of the OPC provider is in Germany, as in other countries sometimes verifications are not required.
