Buy Grape Seed – Extract from Grape Seeds

Grape seed extract is obtained from the seeds of red grapes (Vitis vinifera) and is one of the polyphenol-rich plant extracts. It is characterized by a high proportion of OPC (oligomeric proanthocyanidins), a subgroup of secondary plant compounds. In this category you will find grape seed products from Scheunengut – standardized, vegan and lab-tested.

Origin & Extraction

The seeds are a byproduct of grape harvesting and juice pressing and are dried, ground and gently extracted. This raw material yields a concentrated extract that is adjusted for its polyphenol and OPC content. Grape seed is therefore botanically closely related to other grape extracts such as resveratrol.

Standardization & Form

What matters is the standardized content – high-quality grape seed extracts transparently state their OPC proportion, often around 95%. Grape seed is mostly offered as a capsule or powder, often in combination with pine bark or natural vitamin C. Look for clear amount and content information per daily serving.
