Swanson Grape Seed Extract, Maximum Strength – 60 caps

Grape Seed Extract Maximum Strength from Swanson comes in a 60-capsule pack, with each capsule delivering a concentrated extract standardised to 90% polyphenols. The extract is sourced from California grapes, ensuring a consistent and verified level of this naturally occurring plant compound in every capsule.

Polyphenols are a class of compounds found widely in plants, fruits, and vegetables, and grape seed is recognised as a particularly rich natural source. Swanson’s standardisation process means the polyphenol content is guaranteed at a fixed concentration rather than varying batch to batch — a mark of quality that reflects the brand’s long-standing reputation in nutritional supplements.

These capsules suit those who follow a varied supplement routine and prefer a straightforward, unflavoured format. They are equally well suited to people who prioritise ingredient quality and traceability, given the specified California grape source and the confirmed 90% polyphenol standardisation.
