Grape Seed Extract

Grape seed sits among the richest natural sources of OPCs, and the standardisation is the whole story here: ours is 90%, so 270 mg of every 300 mg tablet is the antioxidant compound itself, not plant bulk. Vegan, non-GMO, clean and third-party tested, with the active content printed on the front.

Proudly made in the USA and the UK to the strictest of standards

A concentrated source of OPCs

Grape seed extract is a concentrated source of oligomeric proanthocyanidins (OPCs), flavonoid compounds present in the seeds and skins of grapes. The purpose of an extract is that most of the tablet is the defined active rather than plant bulk, which makes the standardisation percentage the determining figure. This extract is standardised to 90% OPCs, so each 300 mg tablet provides 270 mg of OPCs.

Standardised to 90%: 270 mg active per tablet

A tablet standardised to 90% is a defined product in a way that an unspecified '300 mg grape seed' is not, because it states precisely how much of the OPC fraction is present. That figure is declared on the front of the label as the only sound basis for comparison.

Vegan, with the active content declared

Manufacturing is cGMP-certified with clean excipients, suitable for vegans and non-GMO, free of artificial colours and fillers. An independent laboratory confirms the OPC standardisation and screens each batch for contaminants, with the exact active content declared.
