How are we different?
The quality of different OPC products on the market varies greatly because OPC values vary according to the method of measurement. Common laboratory tests such as the DMAC or vanillin test can also yield misleading or inflated OPC values of up to 400% of the actual OPC content, whereas the HPLC method shows far more accurate results.
Particularly important for the value of OPC is the content of so-called di- to tetrameric proanthocyanidins. Standard extracts often only achieve a content of 10-20% here. Our OPC 2000 Di- to Tetra Forte from the premium extract of unripe apples shows an extraordinarily high content of these particularly active di- to tetramers of OPC (HPLC method) at 50%. Moreover, the extract also has a unique profile of valuable apple phenols: phenolic acids, flavonoids, flavonols and anthocyanins, which form a synergy as a total complex. In addition to the OPC, the catechins (EC and C), the chalcones and the chlorogenic acid are particularly noteworthy.
Unlike many other OPC supplements, our product is derived using water and edible ethanol without any other chemical solvents. The resulting ultra pure extract is completely natural and has no residues from chemical solvents such as n-hexane, methanol, or acetone. All of our products are guaranteed free from additives such as maltodextrin and peanut powder, which are often mixed into OPC but not required to be disclosed on the label.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

OPC
OPC
OPCs (Oligomeric Proanthocyanidins) named also as vitamin P, are a group of substances belonging to the flavonols, which consist of polymers of catechins and epicatechins. Proanthocyanidins are present in a whole range of fruits and plants, including the seeds and skins of grapes, in berries and citrus fruits, but also in the protective bark layer of trees.
The various proanthocynidins are categorised by their number of units (e.g. monomer for one unit, dimer for two). The exact definition of OPC is unclear and may include only di- to tetramers, di- to pentamers, di- to hexamers, or even all proanthocyanidins except monomers.
For a long time, only the dimers, i.e. consisting of two, and the trimers, consisting of three units, were considered to be bioactive. However, this has since been disproven, allowing a complex interaction of all components of the grape seed extract (including the polymeric proanthicyanidins such as hexamers and heptamers) to be used. OPC compounds are contained in large quantities, especially in pine bark and grape seeds, in which the individual proanthocyanidins differ from each other both in form and in their effect. There is also a notable amount of vital proanthocyanidin-B3-3'-O-gallate in grape seed extract.
