Superior Absorption for Maximum Benefits
Oligomeric proanthocyanidins (OPCs) are the powerful health-promoting nutrients in grape seed extract.* Researchers have found that grape seed extract is one of the most promising botanical extracts in the world for a diverse array of health applications.
Clinical OPC features French grape seed extract VX1, which is backed by 6 groundbreaking scientific studies and provides a strong ORAC value of 2,103,300 per 100 grams. This unique extract is never adulterated and is standardized for only small sized OPCs to better ensure absorption.
Clinical OPC supplies only low molecular weight, tannin-free OPCs for high absorbability.
Many other grape seed extracts include high levels of tannins—OPCs with a high molecular weight—which have limited absorption and few health benefits.
† Supports healthy levels already within normal range
^ Protection from oxidative stress and damage
†† In conjunction with a healthy diet and exercise regimen

Frequently Asked Questions
Tannins are a form of proanthocyanidin (another OPC) found in grape seeds, stems, and skin. As a result, they are found in many grape seed extracts. However, they have a high molecular weight, which makes them very difficult for the body to absorb, and in any case, they don’t provide significant health benefits. Clinical OPC provides only low-molecular weight OPCs, including a complex mixture of flavanolic monomers (catechin, epicatechin, epicatechin gallate) and flavanolic oligomers (dimers, trimers and tetramers).
ORAC, or oxygen radical absorption capacity, is the measurement of the free radical fighting strength of an antioxidant. The higher the ORAC value, the more ability it has to reduce oxidative damage to the cells.
Adulteration is a way that unscrupulous companies cheat consumers. It usually means that a cheap ingredient has been substituted for the expensive one listed on the product label. In other words, consumers believe they are paying for one thing but are getting an inferior substitute instead. Unfortunately, adulterated products—and specifically adulteration of grape seed products—is increasingly common. In fact, an investigation published in the journal of Food Chemistry in 2015 found some alarming results. After testing 21 commercially available products claiming to contain grape seed extract, they found that 70 percent were subpotent extracts or contained no grape seed at all.
- Only 6 were potent grape seed extracts
- 9 were low potency--barely any OPCs (the key beneficial compounds in grape seed), and were probably grape seed mixed with peanut skin
- 6 had NO grape seed extract, but were entirely peanut skin extract, which could be potentially harmful for individuals with allergies
That’s not something you have to worry about with any of our Clinical OPC supplements. Our French grape seed extract VX1 is verified by independent testing to be real grape seed extract, and we guarantee what is listed on the label is what is in the product. Your good health deserves it.
