Life Extension Vitamin C and Bio-Quercetin Phytosome
by Life Extension
"Vitamin C with enhanced quercetin — 1000mg C + bio-enhanced quercetin phytosome for immune and antioxidant synergy"
Overview
Life Extension Vitamin C and Bio-Quercetin Phytosome combines 1000mg of vitamin C with a bio-enhanced quercetin phytosome that provides 15mg of quercetin with dramatically improved absorption (up to 50x more bioavailable than standard quercetin). Quercetin is a flavonoid antioxidant that synergizes with vitamin C — it helps regenerate oxidized vitamin C back to its active form, extending its antioxidant activity. The phytosome technology wraps quercetin in phospholipids for enhanced intestinal absorption.
