Life Extension Vitamin C and Bio-Quercetin combines 1,000 mg of high-potency vitamin C with an ultra-absorbable form of the flavonoid quercetin. Vitamin C is a water-soluble antioxidant that the human body cannot produce on its own, and it supports healthy immune function, collagen formation, healthy iron uptake and cardiovascular health. Quercetin complements vitamin C by helping the body manage oxidative stress and maintain a healthy inflammatory response. The Bio-Quercetin® blend uses soluble fibres (galactomannans) from fenugreek seed to raise quercetin absorption by up to 62 times compared with standard quercetin, so a small 15 mg dose delivers meaningful support. Each bottle contains 250 gluten-free, non-GMO vegetarian tablets — a 250-day supply at the recommended serving.
