Vegan and made in Germany: the production of OPC capsules takes place in Germany and is therefore subject to the strict German guidelines for the production of dietary supplements. We use a purely vegetable capsule shell and therefore the OPC capsules are 100% vegan.
Supply for 8 months: We recommend taking one capsule of OPC grape seed extract daily and in this way supplying the body 375 mg of valuable OPC. One can contains 240 capsules and is therefore sufficient for 240 days or a full 8 months.

In this way, our OPC grape seed extract capsules ensure an optimal supply of secondary plant substances.
Grape seed extract: grape seeds rich in natural plant substances such as oligomer proanthocyanidins. Thanks to a gentle extraction process, the high-quality OPC grape seed extract is produced from the grape seeds - the 500 mg grape seed extract per capsule was obtained from 12.5 g grape seeds.
Certified 75% OPC content: For our grape seed extract OPC capsules, we use a high-quality grape seed extract with real 75% OPC content. The OPC content has been determined by an independent food laboratory using the modern and accurate HPLC process. Each capsule of OPC grape seed extract thus provides 375 mg of pure OPC - analysis certificate see 5. Image in the picture gallery.
