Grape Seed

Discover why grape seed extract is valued for its naturally occurring proanthocyanidins and why concentrated extracts are used in food supplements.

Grape seeds come from the fruit of the grapevine (Vitis vinifera). While often discarded during winemaking and juice production, the seeds naturally contain a rich source of plant compounds known as proanthocyanidins (OPCs).

In food supplements, concentrated grape seed extracts are commonly used to provide higher levels of these naturally occurring compounds than whole grape seeds alone.

The Basics

Understanding Grape Seed

Grape Seeds

Grape seeds are the small seeds found inside grapes. They naturally contain a variety of plant compounds, including polyphenols, flavonoids and oligomeric proanthocyanidins (OPCs).

Grape Seed Extract

Grape seed supplements are available as whole grape seed powder or concentrated extracts. Extracts are produced by concentrating the naturally occurring compounds found within the seeds, allowing consistent amounts to be provided in every serving.

95% Proanthocyanidins (OPCs)

Proanthocyanidins, often referred to as OPCs, are naturally occurring polyphenols found in grape seeds. Our grape seed extract is standardised to 95% proanthocyanidins, providing a concentrated source of these naturally occurring plant compounds.

Frequently Asked Questions

What are grape seeds?

Grape seeds are the small seeds found inside grapes. They naturally contain a variety of plant compounds, including polyphenols, flavonoids and proanthocyanidins (OPCs).

What is grape seed extract?

Grape seed extract is produced by concentrating the naturally occurring compounds found in grape seeds. It is commonly used in food supplements because it provides a more concentrated source of these compounds than whole grape seeds alone.

What are proanthocyanidins (OPCs)?

Proanthocyanidins, often called OPCs, are naturally occurring polyphenols found in grape seeds and several other plants. They are well known for their antioxidant properties and are commonly used to standardise grape seed extracts.

What does 95% proanthocyanidins mean?

A 95% standardised extract means the grape seed extract has been concentrated so that 95% of its composition consists of naturally occurring proanthocyanidins (OPCs). Standardisation helps provide a consistent level of these compounds in every serving.

What foods naturally contain proanthocyanidins?

Proanthocyanidins are naturally found in grapes, grape seeds, cranberries, blueberries, apples, cocoa and certain other fruits and plants.
