How are we different?

Our natural pine bark extract is derived from the bark of wild growing, pesticide-free pine for a particularly high OPC content in natural combination with valuable polyphenols, catechins, and taxifolin. 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.

Furthermore, for the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found on the market, are 100% free from controversial additives such as carrageenans and PEG. We do not use gelatine or pullulan and completely avoid the use of release agents such as magnesium stearate, which is often used in the production of capsule and food supplement powders. We use environmentally friendly amber glass bottles for the packaging of this product.

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.
