Swanson Resveratrol & Quercetin combines three well-regarded plant-derived compounds — Quercetin, Grape Seed Extract, and Resveratrol — into a single convenient vegetable capsule. Each ingredient is carefully sourced and standardised to ensure consistent quality: the Grape Seed Extract is standardised to 90% polyphenols, while Resveratrol is derived from Polygonum cuspidatum root extract, a traditionally used botanical source.

Quercetin is a naturally occurring flavonoid found in many fruits and vegetables, while Resveratrol is a polyphenol associated with a range of plant foods. Grape Seed Extract is a concentrated source of proanthocyanidins and polyphenols. Together, these compounds provide a complementary blend of plant polyphenols in one easy daily serving.

Formulated with a clean ingredient profile — including a hypromellose vegetable capsule shell and rice flour as a filler — this product is suitable for both vegans and vegetarians. With 30 capsules per pack, it offers a convenient one-month supply when taken at the recommended dose of one capsule per day.
