OPC-rich grape seed extract (Vitis Vinifera) Leucoselect®

Leucoselect® grape seed extract (Vitis vinifera) is a plant-based ingredient derived from the by-products of the French wine-growing industry. The seeds, harvested locally, are processed and extracted in France using a standardised method that ensures a high concentration of OPCs — oligomeric proanthocyanidins —, polyphenolic compounds naturally found in grape skin and seeds. OPCs belong to the flavonoid family and are recognised for their significant antioxidant properties. They contribute to neutralising free radicals and help protect cells against oxidative stress. Studies have also highlighted their role in supporting vascular wall integrity and contributing to normal circulation. Supplementing with OPC-standardised grape seed extract is of interest to those looking to boost their antioxidant intake, particularly when diet alone is insufficient to meet daily needs. The Leucoselect® format provides a rigorously controlled OPC content, ensuring consistency and quality with every dose.
