Immune & Antioxidant Support Vitamin C and Bio-Quercetin

Vitamin C on its own is water-soluble and used up by the body relatively quickly — a fact that explains why pairing it with a compound like quercetin can make a meaningful difference in how well it's retained and used.

That's the chain worth noting: quercetin is a plant compound known to work alongside vitamin C, supporting antioxidant activity and immune defence more effectively than vitamin C taken alone.

Life Extension Vitamin C and Bio-Quercetin delivers 1,000 mg of vitamin C plus enhanced-bioavailability quercetin per serving, combining both in a single, clearly dosed formula.

It reflects the same research-driven approach Life Extension has applied to its formulations for decades.
