Overview

Life Extension Vitamin C and Bio-Quercetin Phytosome provides 1000mg of vitamin C with 15mg of quercetin phytosome per tablet. The bio-quercetin phytosome technology (quercetin bound to sunflower phospholipids) increases quercetin bioavailability by 50x compared to standard quercetin. Quercetin is a flavonoid with potent antioxidant and anti-inflammatory properties that synergizes with vitamin C — quercetin helps recycle oxidized vitamin C back to its active form, while vitamin C enhances quercetin absorption. The 250-tablet count provides over 8 months of daily immune support.
