Buy OPC – High-Dose Extracts from Grape Seed & Pine Bark

OPC (oligomeric proanthocyanidins) belong to the polyphenol group and are therefore classed as plant compounds. They are obtained mainly from the seeds of red grapes and from the bark of the French maritime pine, better known as pine bark. In this category, you'll find high-dose OPC products from Scheunengut – standardised to a defined OPC content, vegan and lab-tested.

Origin & Production

There are essentially two sources: grape seed OPC is extracted from grape seeds and is the classic, well-researched raw material. OPC from pine bark (French maritime pine, often standardised as an extract) is considered a particularly pure source. Both variants are gently extracted and then adjusted to their content of oligomeric proanthocyanidins.

Standardisation & Format

What matters most when buying OPC is the standardised OPC content – high-quality extracts often show a content of around 95%. OPC is usually offered as capsules or powder and is often combined with natural Vitamin C. Look for a clear statement of the milligrams of OPC per daily serving, so you can compare products properly.

Häufige Fragen zu OPC

What is OPC and what is it used for?

OPC (oligomeric proanthocyanidins) belongs to the polyphenol group and is therefore classed as a plant compound. It's obtained mainly from grape seeds and pine bark.

What's the difference between grape seed OPC and pine bark OPC?

Grape seed OPC is extracted from the seeds of red grapes and is the classic, well-researched raw material source. OPC from the bark of the French maritime pine (pine bark) is considered a particularly pure source. Both are gently extracted and standardised to their content of oligomeric proanthocyanidins – ultimately, the choice comes down to personal preference.

How can I tell high-quality OPC apart?

What matters most is a standardised, clearly declared OPC content per capsule or serving – it's the only way to know how much active plant compound you're actually getting. Our OPC products are high-dose, standardised, vegan, and lab-tested. Look for a transparent statement of the pure OPC content, not just the overall extract weight.

How is OPC taken?

OPC is usually available as a capsule or powder and is typically taken once a day. Many people like to combine OPC with vitamin C. Follow the recommended intake stated on the product. As a purely plant-based product, it's also suitable for a vegan diet.
